| pcie_bus_perf : Understanding the capping of MRRS Posted: 01 Jan 2022 05:05 AM PST Quoting the linux kernel documentation for boot parameters : pcie_bus_perf : Set device MPS to the largest allowable MPS based on its parent bus. Also set MRRS (Max Read Request Size) to the largest supported value (no larger than the MPS that the device or bus can support) for best performance. I fail to understand why the MRRS should not be larger than the MPS "for best performance". I mean if a device can do MPS=X and MRRS=4.X then read requests could, in numbers, be less hence the bus less busy compared to a MMRS=X situation, even if the satisfaction of the request needs to be split in 4. BTW, I know the concept of "fair sharing" and understand the impact of large MRRS on that sharing but I never understood fair sharing synonymous to best performance. |
| Raspberry Pi doesn't recognize HP PSC 750xi Scanner Posted: 01 Jan 2022 04:51 AM PST I posted this to raspberrypi.stackexchange yesterday with no responses and only 4 views, so I'm reposting and expanding the original post here to reach a wider/different audience. I have an old Pi-3 running Stretch. I have what apt-get install tells me is the latest version of everything installed. I plug in an old HP PSC 750xi All-In-One USB printer/scanner. The Pi recognizes the printer features of the device, and I can successfully configure CUPS to use the printer. But I cannot get the Pi to recognize the device's scanner. I have a separate laptop running Ubuntu 20. When I plug the USB device into that laptop, I can use hplip's hp-scan tool to successfully scan. But none of the Pi's hplip or sane tools (hp-setup, hp-probe, hp-check, hp-scan, scanimage, sane-find-scanner ...) recognize the USB scanner. Clearly, as the Ubuntu test proves, hplip does support scanning for this all-in-one printer/scanner. And hplip documentation indicates that the device is supported both for the Pi hplip version (3.16.11) and for the Ubuntu version (3.20). I also have an HP 6978 Network printer/scanner that the Ubuntu system sees on the network and can manipulate with the hplip tools. The Pi's CUPS server sees and can use that network printer. But, like the USB device, the Pi fails to 'see' the network scanner. My understanding is that these scanners are supported through use of the libsane-hpaio backend. Yes, I have installed the libsane-hpaio package on the Pi. I've run scanimage on the Pi with SANE_DEBUG_DLL=128 and SANE_DEBUG_HPAIO=128 but the output simply reports no scanners found without indicating any errors of any kind. On the Ubuntu system, the same debug output shows successful discovery of both the network scanner and the USB-connected scanner. But there appear to be more fundamental issues. The full lsusb output is now reporting: theadmin@RASSERVER:~ $ lsusb Protocol spec without prior Class and Subclass spec at line 23291 Bus 001 Device 005: ID 0bc2:231a Seagate RSS LLC Expansion Portable Bus 001 Device 006: ID 03f0:1511 HP, Inc PSC 750xi Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc.

(formerly SMSC) SMC9514 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
It's that very first line I'm concerned about. I'm thinking this is a possible Python version issue as python -V reports Python 2.7.13. But Python3.5 is installed too (though I have no idea which package might have installed it,) and python3 -V reports Python 3.5.3. So, I'm thinking half the packages are using python v2 and half are using v3 and I don't know which is using which. Nor do I know how to configure them to use a different version. Plus, I'm a bit hesitant to even try to reconfigure/upgrade the base python from v2 to v3 for fear of breaking the entire system. And I'm concerned that the libusb and usbutil packages are so old, while hplip and its companions are much newer ... some kind of a mismatch somewhere, but I hardly know where to start. I hate to rebuild the Pi from scratch because I don't want to have to rebuild its LAMP stack, web server, nextcloud server, etc. but that may be my only option. I cannot find any missing packages or dependencies on the Pi. I have tried removing and re-installing hplip and a number of other packages. Clearly, there is some configuration difference between the Pi and the Ubuntu platforms. But after several days of struggle, I'm stumped. Anyone have any ideas? |
| Is have a file-based friendly fuse tool？ Posted: 01 Jan 2022 04:20 AM PST I'm looking for a file-based, size-scalable and mountable fuse. - I trid tar with archiveamount, but fail high probability when update (maybe It's too older?)
- I trid file image with filesystem(ext4, ...), but size-scalable is difficult
- I trid sparse-file but It's only valid in local system, It can't use as a normal file, File will recovery full-size when copy.
- I saw fuse-archive,squashfs but It's readonly
- I trid fuse-zip, It work OK, But I still want to look for others again
It may be that my search keywords are inappropriate, Is have some/more better tool or function to do this usecase? |
| Trigger keyboard shortcut from bash alias/function Posted: 01 Jan 2022 03:45 AM PST Here's the thing: I'm running Windows 10 and I'm using Windows Terminal (WT). In WT there is a shortcut for splitting the pane (SHIFT+ALT+MINUS/PLUS). The issue is that the new pane is on my root directory. I would like to write an alias in my profile.ps1 that navigates to a particular directory, splits the pane, and navigates the new pane to the same directory. I have gotten the navigation part working with: Function path_desktop {Set-Location -Path "C:/../Desktop"} Set-Alias -Name goto_desktop -Value path_desktop
But is it possible to call a keyboard shortcut from within this type of function? Something to the tune of: Function openSplit {cd "path"; SHIFT+ALT+MINUS; cd "path"}
Obviously, this doesn't work. But is there a way to achieve something like this? I hope that made sense... haha. Thanks! |
| iptables port forwarding from external ppp0 to internal server Posted: 01 Jan 2022 03:54 AM PST Actually the same question to this one. But I didn't get answer there either. My scenario is: a Linux box with two NICs acting as a router, running iptables rules for masquerading, firewall, ... etc. I'd like to forward certain port to internal servers which only have LAN IPs. The router server uses ppp0 as external interface and 192.168.212.50 as internal IP. I'd like to forward port 2000 from external (connecting to hostname:2000) to internal 192.168.212.51:8088. The sysctl net/ipv4/ip_forward has been set to 1 since it has masquerade set. Now when I try port forwarding from external ip (hostname:2000) it is always timed out. In the log I could see the packets being dropped. The iptables rules is here: https://pastebin.com/au9QDhQf - If I setup the port forward to LAN only, i.e., not defined
-i $EXT_IF and connect with http://192.168.212.50:2000/ it could work. - I also checked this post. However, since I have already had MASQUERADE set the second rule
iptables -t nat -A POSTROUTING -j MASQUERADE does not work here. Any help will be very appreciated. |
| How to customise the appearance of notify-send? Posted: 01 Jan 2022 03:25 AM PST I am running linux mint and use the notify-send command for various purposes, and of course also receive notifications from regular applications e.g. discord or MS Teams When using Cinnamon DE, they look pretty normal, and I can even add icons to my custom notify-send calls to make it clear what is going on However, I recently started using XMonad WM, and I'm finding that not only are the regular application notifications ugly, but my custom ones which have nice icons in them also follow that same ugly style (please excuse blurry screenshot): 
For example, the above notification should contain an icon as per this command: notify-send --hint=int:transient:1 'Connecting to VPN... Check 2FA Device.' -i myicon

| FreeBSD 13.0 Release package support Posted: 31 Dec 2021 09:44 PM PST I downloaded and installed FreeBSD 13.0 on a old IBM IntelliStation M Pro I have as a spare. My intention was to use it as a file server replacing an old machine running 4.0. I got it up and running except for X11. This machine has an Nvidia GeForce4 Mx440 08x card codenamed NV18. I believe an appropriate driver can be found in /usr/ports/X11/nvidia-driver-390-390.144 but, it seems packages are not available for release 13.0 yet. It seems quite involved to re-compile it from a ports collection as the system source tree needs to be installed. - will "packages" be released for Release 13.0?
- is there a "simpleton" way to get/install my video driver?

| Does zsh have any equivalent to BASH_ENV? Posted: 01 Jan 2022 02:56 AM PST I would like to be able to use something like the BASH_ENV variable in zsh, however I can't find anything like it by Googling. From man bash: BASH_ENV
If this parameter is set when bash is executing a shell script, its value is interpreted as a filename containing commands to initialize the shell, as in ~/.bashrc. The value of BASH_ENV is subjected to parameter expansion, command substitution, and arithmetic expansion before being interpreted as a filename. PATH is not used to search for the resultant filename. Does zsh have something like this? |
| Extrating timestamps from filename to split mp3s Posted: 01 Jan 2022 03:24 AM PST I have a bunch of mp3 files in a folder. They are recorded from cassette tape, and the individual tracks need to be separated out. This is one one the filenames: Gobbolino the Witch's Cat, 10:52 The Hare & Tortoise, 14:52 The Shoe Tree, 24:22 The Emperors New Clothes, 34:11 The Red Nightcaps, 37:07 Aldo in Arcadia (1), 40:37 The Forest Troll.mp3
You can see it has timestamps within the filename, indicating the start of each track. The first track is not timestamped since it always starts at 00:00. And the last track should always go to the end of the mp3. Somehow, I want to extract these timestamps in order to create separate files. If the file above were split correctly the output would be: Gobbolino the Witch's Cat.mp3 The Hare & Tortoise.mp3 The Shoe Tree.mp3 The Emperors New Clothes.mp3 The Red Nightcaps.mp3 Aldo in Arcadia (1).mp3 The Forest Troll.mp3
I know how to loop thru files, and how to cut a file with ffmpeg, but I don't know how to extract the timestamps and track names from the filename. I'm using zsh, and here is my current code: for file in *; do if [[ -f "$file" ]]; then # extract timestamps and loop thru, for each timestamped section ffmpeg -ss TIMESTAMP_START -to TIMESTAMP_END -I "$file" -acodec copy TRACK_NAME.mp3 fi done

| How to avoid audio recording fade in? Posted: 01 Jan 2022 05:30 AM PST Audios recorded from the microphone start with a pop and a fade in. I tried 2 mics from two hardware inputs. I found this solution that describes my problem but Fedora 35 has no default.pa file: In the /etc/pulse/default.pa file, comment out this line: load-module module-suspend-on-idle
It seems this is just default Pulse Audio behavior and essentially tries to save resources by "dimming" sources of audio that become idle for "too long." I haven't really timed it to figure out how long "too long" is, but with the change above, it doesn't matter anyway What would be the Fedora 35 equivalent? Indeed if I start recording immediately after another recording there is no fade in but the pop persists. I found the pipewire-pulse systemd user unit but no obvious setting: [Unit] Description=PipeWire PulseAudio # We require pipewire-pulse.socket to be active before starting the daemon, because # while it is possible to use the service without the socket, it is not clear # why it would be desirable. # # A user installing pipewire and doing `systemctl --user start pipewire-pulse` # will not get the socket started, which might be confusing and problematic if # the server is to be restarted later on, as the client autospawn feature # might kick in. Also, a start of the socket unit will fail, adding to the # confusion. # # After=pipewire-pulse.socket is not needed, as it is already implicit in the # socket-service relationship, see systemd.socket(5).

| Is it possible to permanently disable the gnome-keyring passphrase? Posted: 01 Jan 2022 05:28 AM PST Whenever I login using the fingerprint sensor instead of the login password, a popup is displayed from gnome-keyring to enter the login password in order to unlock the various certificates that are stored there. 
This is quite annoying, because it steals the focus, and doesn't let you do anything else until the password is entered. It won't even let you change the keyboard language, so if you had it in a different language than the password before the reboot, you are screwed. I wasn't even able to take a screenshot of the popup, which is why the quality of the picture is so low - it was from my mobile. A partial solution to this problem is to set the keyring password to an empty string, by opening the Passwords and Keys app (type keyring into the search bar), and using the menu as below: 
But is not a very good solution, because the keyring password keeps being reset, and you have to repeat the same process all over again. I am not sure if this happens on some reboots, or when there has been an update. So my question is twofold: Am I correct in my thinking that the keyring passphrase doesn't add any security, and is redundant, since the system uses secure boot, with UEFI setting that doesn't allow boot from any other disk without an admin password, LUKS full disk encryption, and there are no other user accounts on the laptop? If (1) is correct, then how can I permanently remove the keyring password, in a way that it doesn't get added automatically again? Edit This question is related, but the answer doesn't offer a workaround: Why is my "no password" setting on my login keyring frequently reset? |

| How to restore (normalize) HDD spinoff timeout in LXLE? Posted: 31 Dec 2021 10:46 PM PST After the last update on my system, the timeout setting for turning off the hard disk was broken. This problem manifests itself as a constant shutdown and spinning of the HDD motor at intervals of about 10-20 seconds. The hard drive itself is still alive, but with such treatment it will not live long. I made sure the drive is working, connect my laptop to the charger. Once I did that, the problem with shutting down the disk was gone. It seems the disk didn't turn off at all, but that's not certain. However, as soon as I finished charging, the problem returned immediately. Moreover, this problem does not appear on the account login screen. The drive starts to turn off only after logging into my account. I only have one user, so I didn't check what happens if I log into another profile. However, in any case, it is desirable for me to restore my profile.

I still do not understand why this is happening with the HDD. I have tried: sudo vi /etc/smartd.conf (changing -n mode)- Different numbers in
sudo hdparm -S 129 -B 120 /dev/sda None of this worked. Interestingly, even if I boot with an older kernel version, the HDD shutdown problem persists. At the same time, the Wi-FI adapter, the display driver does not work (the background image is simply stretched), but the problem with the constant shutdown of the disk remains. What is the problem that caused the HDD to instantly (without any timeout) turn off when it is idle? How can I fix this problem? |

| Why do i get “Permission denied” errors from using Weston/Wayland Posted: 31 Dec 2021 11:19 PM PST I have built a Linux system with Buildroot (2021.05) to run on a raspberry pi 4. My graphics stack include using mesa (vc4, v3d, kmro), Wayland / Weston with a DRM back-end. Also installed kmscube, which runs perfectly with the rotating cube reporting a frame rate of 60fps The main application to be run in Weston is a wpewebkit application. So far, the application runs but without any hardware acceleration. The reported frame-rate of the embedded browser is about 5fps. When i exit from the application, i see the following messages displayed on the terminal atomic: couldn't commit new state: Permission denied repaint-flush failed: Permission denied atomic: couldn't commit new state: Permission denied repaint-flush failed: Permission denied atomic: couldn't commit new state: Permission denied repaint-flush failed: Permission denied
...... My system is setup to bypass any login prompts and start as root by editing my inittab file. When i run the who command, i get nothing on the terminal. If i run the command whoami, i get the output root. Can someone point me to why i am getting the "permission denied" errors from Weston / mesa. |

| CentOS does not recognize compiled boost library Posted: 01 Jan 2022 12:00 AM PST I have built and installed boost using the following steps: # Boostrap and install JOBS=`grep -c ^processor /proc/cpuinfo` wget https://dl.bintray.com/boostorg/release/1.67.0/source/boost_1_67_0.tar.bz2 tar xf boost_1_67_0.tar.bz2 cd boost_1_63_0 ./bootstrap.sh ./b2 -d1 -j${JOBS} --with-thread --with-filesystem --with-python --with-regex -sHAVE_ICU=1 --with-program_options --with-system link=shared release toolset=gcc stage ./b2 -d1 -j${JOBS} --with-thread --with-filesystem --with-python --with-regex -sHAVE_ICU=1 --with-program_options --with-system link=shared release toolset=gcc install sudo bash -c "echo '/usr/local/lib' > /etc/ld.so.conf.d/boost.conf" sudo ldconfig
Then, I try to build mapnik which uses boost. I checkout mapnik and run ./bootstrap.sh and ./configure. I get the error "Could not find required header or shared library for boost filesystem".

(Build steps courtesy of keisan) Why doesn't the system find the boost library 1.67? I don't remember installing boost 1.63. I have compiled and installed 1.67, but the build system does not use it. Where does the system look for boost on the system? I deleted all libboost_* files in /usr/local/lib and /usr/lib64, but still don't know where the system looks for boost. Can someone give a tip on how to tell the system about the newly compiled software? |

| Minimal installation of Oracle Java 8 on Debian - headless, with no GUI Posted: 01 Jan 2022 02:07 AM PST In another question here (Minimal Java installation for Linux with no GUI) I found some information about headless installation of OpenJDK, but I would need this with Oracle Java 8. I need Oracle Java, because I use an ARM architecture (Raspberry Pi 2) to run a Minecraft Spigot server, and red many times that ARM version of OpenJDK lacks critical optimalisation to provide suitable performance I want version 8, because Spigot also recommands to use this version for any Minecraft-related purpouses; OpenJDK does not have version 8 yet anyway I want it headless, since I run my Raspberry server in console mode, with all GUI/desktop environment components uninstalled, to save storage place and performance. My current system is the strongly Debian-based Raspbian Wheezy (Kernel ver. 3.18.; released 2015-05-05). This comes with a pre-installed Oracle Java 8, but it was deleted when I wiped out the GUI and desktop components (along with various other useless softwares) to make a minimal platfrom. Then I tried to re-install it using the following command: # apt-get install oracle-java8-jdk
it provided me a huge list of packages to install, which, as I was able to recognize them, contained mostly fonts, icons, language files, and x11 (x-server-realted) libraries, all nice damned GUI staff, what I absolutely do not need - and cried for >200 MB storage space. Finally to my question: is there any way to install an Oracle Java Runtime Environment without these GUI conponents? Maybe I should manually sort out unwanted packages - but how could I know which ones are really need for Java to run on console, or may it cause instability if I miss packages which are in the dependancy list, but functionally would not need to Java? The list of required packages (maybe they will help): fontconfig fontconfig-config hicolor-icon-theme libatk1.0-0 libatk1.0-data libcairo2 libdatrie1 libfontconfig1 libgdk-pixbuf2.0-0 libgdk-pixbuf2.0-common libgraphite2-2.0.0 libgtk2.0-0 libgtk2.0-bin libgtk2.0-common libharfbuzz0a libjasper1 libjpeg8 libpango-1.0-0 libpango1.0-0 libpangocairo-1.0-0 libpangoft2-1.0-0 libpangox-1.0-0 libpangoxft-1.0-0 libpixman-1-0 libthai-data libthai0 libtiff4 libx11-6 libx11-data libxau6 libxcb-render0 libxcb-shm0 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxdmcp6 libxext6 libxfixes3 libxft2 libxi6 libxinerama1 libxrandr2 libxrender1 libxtst6 oracle-java8-jdk ttf-dejavu-core x11-common |
| Match exact string using grep Posted: 01 Jan 2022 03:32 AM PST I have a text file: deiauk 1611516 afsdf 765 minkra 18415151 asdsf 4152 linkra sfsfdsfs sdfss 4555 deiauk1 sdfsfdsfs 1561 51 deiauk2 115151 5454 4 deiauk 1611516 afsdf ddfgfgd luktol1 4545 4 9 luktol 1
and I want to match exactly deiauk. When I do this: grep "deiauk" file.txt
I get this result: deiauk 1611516 afsdf 765 deiauk1 sdfsfdsfs 1561 51 deiauk2 115151 5454 4
but I only need this: deiauk 1611516 afsdf 765 deiauk 1611516 afsdf ddfgfgd
I know there's a -w option, but then my string has to mach whole line. |

| Drivers for HP ScanJet 2400 on Linux Posted: 31 Dec 2021 10:05 PM PST I'm trying to install my scanner "HP ScanJet 2400". I followed the recipe from here: http://www.elcot.in/linuxdrivers_download.php, However, it was not possible at all to detect it, when working in CentOS, Fermi & OSuSE OS. Doess anyone have any suggestions on how to get this scanner working? |
