| Touchpad stopped working after hibernate on Thinkpad X1 Carbon 2nd Gen Posted: 26 Jun 2022 07:08 AM PDT So whenever the laptop goes into hibernate the trackpad will stop working. If I restart or shut down it will come back. I have seen a number of posts about this, like this one: Touchpad stopped working after hibernate on Thinkpad X1 Carbon In the answer, they said they have changed suspend from "S3 Linux" to "Windows/Linux", in the BIOS and the touchpad seems to be working just fine after a wakeup. Is someone able to advise how I'd go about changing this, please? System info: X1 Carbon 2nd Gen Ubuntu 20.04.4LTS 64bit GNOME 3.36.8 Windowing System X11 |
| Posted: 26 Jun 2022 07:04 AM PDT I am looking for tips on enhancing the operating system, which is GNU, by modifying the kernel, which is linux, to get extreme gaming performance. I have done a lot of research over the years on this subject matter and have a pretty good setup right now. GNU, is the fastest operating system for gaming right now in 2022, and is lightning fast with modern hardware, so much so that I can interact with the game world faster than all other players, and it even looks like I'm using hacks, when really, I'm just using my hardware like it's meant to be used, with my GNU operating system of course, which is designed to allow me to actually use my computer, instead of my computer using me. The bottleneck for performance I mainly have right now, after having optimized my operating system, GNU, to it's maximum capabilities, is the kernel, which is linux. I have started researching the kernel, and it's potential to be optimized for maximum throughput to my hardware, so I can get extremely good performance, generally, and also for gaming, but I can't seem to find any information on optimizing the kernel for gaming, since everyone is actually just talking about GNU, in reality. So my question is... (and given a generic linux kernel) What are some options for optimizing the kernel to allow maximum throughput/performance for gaming? |
| Network Manager is Not Sending Notification When Connecting to VPN Server in MX Linux Posted: 26 Jun 2022 06:28 AM PDT I am using MX Linux 21 XFCE pretty much unchanged from stock. I manually create VPN connections in Network Manager using Openvpn. Its been pretty much trouble free for the most part. One day I was suddenly not receiving network connection notifications when connecting to either ethernet or wifi and also when connecting to a VPN server (which I do manually). I did not choose "don't show this again!" I asked on the MX forum and they told me how to turn nm-applet back on on using the MX Settings GUI. Normally I would have used dconf, but that is not an option in MX. After turning notifications back on, I marked the request solved because I thought it was fixed. And it was partially. I got notified when connecting to the eth0 or wan0 but not when connecting to a VPN server like I used to. Given the circumstances I assume that a plug-in configuration file (perhaps for OpenVPN?) did not get the message to turn notifications back on. Does anybody know the following:
Goggling for two hours found lots of interesting network problems but nothing about notifications except how to turn them on and off the usual way and nothing about notifications for VPN connections. P.S. I do confirm that the VPN connections are working after connection using {$ nmcli con show --active}. I have not had any problem with VPN connections except when using the VPN provider's software. Works perfectly using Openvpn except for the sudden loss of notifications for no apparent reason. |
| Dualboot : Install Win10 alongside Debian, not the opposite Posted: 26 Jun 2022 06:17 AM PDT I have Linux Debian installed on my laptop for some years (HDD0, sda). I just added a 2nd hard drive that holds Win10 (HDD1, sdb) I would like to setup a dualboot with these 2 OS. I found tons of tutos to implement dualboots but they seem to apply when Windows is installed first then linux in a second step; and I'm not a GRUB specialist... I can access Win10 hard drive and browse within the file system from Linux. I tried sudo grub-install -> no sucess I tried os-prober -> return is empty If I change the boot options in the BIOS, in order to boot Win10/HDD1 first, instead of Debian/HDD0, it does not work : Win10 is skiped and Debian is launched. I guess win10 is not well recognized as a bootable OS... Can any body help me to fix this issue and setup the dualboot ? Thanks Cez |
| Change color of title bar in Konsole terminal emulator Posted: 26 Jun 2022 06:11 AM PDT I'm using Konsole terminal emulator in Debian bullseye. But it's still showing default grey colored tab bar. Thanks in advance. |
| Shouldn't we say Gnu stack exchange not linux or unix [migrated] Posted: 26 Jun 2022 05:47 AM PDT Shouldn't we call this the Gnu stack exchange and not call it the linux or unix stack exchange... We aren't here to ask questions or talk about the kernel We are here talking about the gigantic suite of free programs designed to allow people to use computers, and interact with computers with ethical applications, that aren't inherently deceptive. It should be seen as the ultimate irony, that linux, is the common name, but for something completely different, Gnu which is the basis of "linux" computing in reality, whereas the kernel is really small in comparison. It's more like a suite of drivers that your real, gnu based software utilizes in order to provide us with a complete operating system. It might seem trivial of course, it's the commonly used term to call it linux, and they both work together regardless along similar lines to achieve a similar goal, but I think it's more important to use language that is in the first place, honest, and directly related to the significant information in the first place. I've been starting to study computer science more frequently, and have found throughout the programmatic world, a kind of systematic misappropriation of language to describe all sorts of concepts, which then makes it much more difficult to understand more complex subject matter. I think that fundamentally the ethics of this operating system we all use, are absolutely a part of it's programming, and that that is extremely important to emphasize. |
| How to emulate usb-mtp device with virt-manager? Posted: 26 Jun 2022 05:01 AM PDT I am trying to emulate an mtp device with virt-manager.

How can I configure virt-manager to do this (custom xml welcome)? |
| how to detect memory leak in linux kernel due to slab leak Posted: 26 Jun 2022 04:58 AM PDT How to observe any memory leak in linux kernel due to any slab leaking? I just wanted to analyse how memory leak is detected due to increase in size of the active objects in one of the slabs in /proc/slabinfo. Can anyone explain with any sample driver example on how kernel detect memory leak due to slab leakage. Also which slabs or component need to be taken care of while observing memory leak in kernel in /proc/meminfo and /proc/slabinfo |
| How to Change Default Boot Kernel of Pop OS 20.04 Posted: 26 Jun 2022 04:36 AM PDT I use Pop OS 20.04 and recently the kernel was upgraded and it caused some issues so I had to switch back to my previous kernel version. (More specifically, the kernel was upgraded to As you might know, Pop OS uses Unfortunately in contrast to So I searched for other options to change the default boot kernel and all I found was this article.

| Are Superblock and Master File Tables the same thing? Posted: 26 Jun 2022 03:46 AM PDT What is the difference between a superblock and a Master File Table (MFT)? Both seem to be tables that keep track of files within a filesystem, but are there other differences? The only difference I found was that the first is used for Ext4 filesystems and the other for NTFS filesystems, but are there any others? |
| Debian - Create new partition with fdisk and set size ( Last sector ) Posted: 26 Jun 2022 03:04 AM PDT please could someone help me with my problem of create new disk partition in Debian ? I'am using Proxmox where I have created a few virtual machines. On one of virtual machines where have installed Linux - Debian I have problem with enough free disk space. So I decied that I created new partion on disk just for backup files. Step 1. I resized disk in Proxmox from 100GB to 250GB Step 2. I logged in to the Debian where I would want to create new partition for storage backup files . Partition shoud have 70GB Step 3. I run fdisk to create new partition + I'am attaching screenshot (create-new-partion-fdisk.jpg ) where I mark up few command and option that I select, but I have problem that I can't set size of partition to 70GB (+70G). I when i try it set value "+70G" for "Last Selector" question I get Error "Value out of range"
Please could you help me how I can achieve this the most easy way ? I don't have such experience with Debian so if some kind soul would help me I would be glad for that ! Specific commands would be extremely halpful Thank you ! |

| Touchpad stopped working after hibernate on Thinkpad X1 Carbon Posted: 26 Jun 2022 06:02 AM PDT I've got a Thinkpad X1 Carbon Gen 9. When I hibernate on Ubuntu 21.10 or Pop!_OS 21.10 or Manjaro, the touchpad either stops working after resume or the cursor moves very choppy. Both with Wayland and xorg. Kernel on Ubuntu 21.10: 5.13.0-22.22; Pop!OS: 5.15.5-76051505-generic; Manjaro - unsure. I'm using Gnome. Looking for a way to fix this, so that the touchpad is fully working post-resume. I tried reloading the kernel module with: I also tried dis-/enabling the xinput device: And I also tried removing/loading the In syslog (Pop!_OS): No changes.

Thanks NOTE: I also have W10 installed along side PopOS and W10 is working fine. |
| Build the Linux kernel without gcc optimization Posted: 26 Jun 2022 07:02 AM PDT I follow one of many tutorials found on Google results to build and debug the Linux kernel with gcc and kgdb/gdb. And I end up by discovering that is all waste of time. Since I can't compile the kernel without gcc optimization -O0 neither -Og. There's no config option for removing optimization. And last but not leat, Linus said years ago that is against debugging. Saying that kgdb must exist for some reason. I was wondering if there is a way to get rid of variables/arguments "optimized out" and let the debugger step through the code sequentially and not jumping from everywhere to everywhere? |

| How do I route a spare network interface through an SSH tunnel? Posted: 26 Jun 2022 04:07 AM PDT I just bought a Raspberry Pi and I am wanting to route an ad hoc wireless network interface fully through an SSH tunnel that was created using another wireless interface. I want to do this so that I can have a secured and private connection to the internet at places with public WiFi. I know this would be easier to do all on one computer, but I would like to have it on the RPi too since I use it for other network related things when I am using the internet, and then just simply connect to the ad hoc network from my laptop/phone. This will really help me with my iPhone because it does not support an SSH tunnel locally. How should I go about doing this? Thanks in advance for all of your help. |
