| Cannot set Wine prefix to location of steam game's prefix on Pop!_OS 20.04. Why? Posted: 30 Sep 2021 10:47 AM PDT So, I'm a regular player of the game Geometry Dash. Which (as some of you fellow GD players reading this know) doesn't have a Linux version, but it can be run with Proton. Now, there's a very popular hacked client in the GD community called Mega Hack, which (yes) does have hacks for cheating like no-clip or speedhack (v6 only). But it also has some useful non-cheating hacks like Practice Music Hack (which plays the level's music in practice mode instead of OcularNebula - Stay Inside Me) and much more. I've found a thread on the MegaHack GitHub repo saying, you can get megahack to work by changing the wine prefix but... it doesn't seem to work for me. The command I tried is: and the result was that it didn't work and the console spat out output way too long to put into this thread so here's a pastebin link. How can I possibly fix this? I really want to get MegaHack running.  |
| Why is the command called which and not where? Posted: 30 Sep 2021 10:38 AM PDT Logically, you would want to search for the location of the executables, hence "where" are they, but not which.  |
| Executable doesn't run on boot-up when changed to write the logs to a file Posted: 30 Sep 2021 10:43 AM PDT I am running an executable on boot-up, and the executable prints logs via So to see the logs, I changed the application such that it writes to a file instead but the executable doesn't seem to run on boot-up after this change, even though the service that's supposed to run this executable is running. Writing to a file works perfectly fine when run manually and not on boot-up.
Did a sample test - when there's a loop, and the executable is pushed, on boot-up it runs but as soon as the loop is commented out, the executable no longer runs.  |

| Android emulator crashing ubuntu when interacting with panel Posted: 30 Sep 2021 10:03 AM PDT I am using ubuntu 20.04. I recently installed android studio, and the emulator seems to be buggy at best. Specifically when I interact with the side panel of the AVD instance, it crashes. Inspecting and crashes the application. Android studio yields following error: Most suggestions with the error seems to revolve around old/updated drivers for graphics, however my machine does not have any graphics card and I have chosen to use software to emulate graphics. I am not sure what to make of the error.  |
| GNOME/gdm disable reveal password button Posted: 30 Sep 2021 10:03 AM PDT On the gdm login screen and on the GNOME lockscreen in the password entry box there is this little password reveal button at the right side. Since this is a toggle some classmates were able to trick me into showing a good portion of my password by just pressing this button while I was away and watching me typing my password in. Now is there any way to remove this button or show the password only while it is pressed? I've found really NOTHING on this topic on the internet except this askubuntu article asking for exactly the opposite what I want.  |

| Raspberry Pi OS for PC not booting up Posted: 30 Sep 2021 09:03 AM PDT I downloaded Raspberry Pi OS for desktop (2021-01-11-raspios-buster-i386.iso, Debian Buster with Raspberry Pi Desktop from here, Kernel version: 4.19, Release date: January 11th 2021). My computer is an HP 15-db1000AU notebook with 64 bit AMD Ryzen 3 2.6 GHz with Radeon Vega Graphics, 4GB RAM. I made a bootable USB using Rufus 3.15, using all default settings provided when the iso was loaded. I tried booting from the USB, both with persistence and without persistence. In both cases there is some text in the beginning, then the computer boots up to the raspberry pi logo, then goes into a blank screen with a blinking cursor and nothing else happens. If I forcefully turn off the laptop by pressing the power button, there is text saying something like could not mount/unmount removable media and the computer suddenly turns off. How should I troubleshoot this? Is this a live OS? Is there any way to try out this OS without actually installing it on a hard drive?  |
| AMD Epyc 7452 having CPU base clock as max clock speed & not boosting to boost clock? Posted: 30 Sep 2021 09:01 AM PDT I have an AMD Epyc 7452 CPU on an ASRock Rack ROMED6U-2L2T board running Proxmox 7 a linux system and running This CPU however is, according to its data sheet, able to boost to 3.35ghz, which I think I have never seen it do. In the Bios I can only set the Core Performance Boost to 'Auto' or 'Disabled' (it is set to 'Auto') and looks like this:
Is there anything I can do to get the CPU to boost to its (advertised) max clock speed and/or where could the culprit be.. is it the bios that's causing this or is it a missing configuration somewhere in Proxmox / linux?  |
| Is it possible to customize grub using grub-customizer in Fedora? Posted: 30 Sep 2021 08:46 AM PDT I recently switched from Ubuntu to Fedora, and I installed
Few topics are opened on Fedora's forums but they keep circling to other topics. Some resources I've tried looking at: https://ask.fedoraproject.org/t/grub-customizer-fedora-entry-not-visible/12526 https://www.reddit.com/r/Fedora/comments/epqg4j/how_can_i_install_grub_customizer_on_fedora_31/ https://www.reddit.com/r/linux4noobs/comments/gvumqx/no_options_of_fedora_in_grub_customizer_help_to/ https://docs.fedoraproject.org/en-US/fedora/rawhide/system-administrators-guide/kernel-module-driver-configuration/Working_with_the_GRUB_2_Boot_Loader/ After some reading, I came to know that from Fedora 30 and above, there has been changes in BLS(no idea what that is).

| GNOME limited refresh rate with dual monitors Posted: 30 Sep 2021 08:37 AM PDT I recently installed Pop_OS! on a new disk in my computer, coming from Arch (which I can still boot to). There are a few kinks I need to work out and one in particular seems to severely limit my monitor refresh rate. I have:
While the GNOME display settings allows me to set the refresh rate to 240 on my primary monitor, the actual DE is clearly still limited to 60, presumably due to the other monitor. If I disable the other monitor in settings, I get a smooth 240 Hz rate on my primary monitor, in regards to the DE animations and games. Otherwise, only the mouse cursor moves at a higher rate, and everything else slumps to 60. Is this fixable or is this some limitation in GNOME? In Arch, I used Cinnamon. I was able to use 240 Hz on my primary monitor and 60 on the secondary (but only after disabling V-sync in the DE settings). If I run  |

| Posted: 30 Sep 2021 09:04 AM PDT What is the easiest, most vanila way to restore a saved ipset rule in centos7, without needing to install any extra packages or plugins? Background... I have googled this but I seem to be going around in circles (articles telling people to google it, articles with steps which don't apply to my distro, articles with steps which simply don't work (example I have recently created a list using ipset for whitelisting a group of IPs. I added the list into my firewall rules ( Come to days after I find that the firewall is not running. On investigation it has failed to start, with the error that my rule doesn't exist. So I now know that ipset rules aren't persistent on reboot I need to reload them. As I said I have tried to find out how to do this via google, but all of the page 1 results just don't really work for me for various reasons. One particular guide suggests editing the ifcfg-eth0 file and adding a Basically is there a simple way to restore an ipset set from a file in centos7 so that it exists before the iptables service tries to use it?

| Pip breaks when switch to Python3.7.9 using update-alternatives on Debian Posted: 30 Sep 2021 08:39 AM PDT I am on Debian 11 which comes with python3.9. But I don't need it, I need python3.7. So, I installed pythonn3.7.9 and updated the alternatives. The problem is that when I switch the python version to 3.7.9, I can't install anything using pip. I get the following error in But when I switch back to Python3.9 then Pip works. I don't know how to fix this. I looked it up on Google, but couldn't find an issue where anyone faced a similar problem.

| Lowering/Disabling touchpad acceleration in GNOME 40 (Wayland) Posted: 30 Sep 2021 10:53 AM PDT I have set the touchpad speed slider to ~50% in Mouse & Touchpad Settings. I find this good enough most of the time but if I move my finger a bit too fast, the pointer flies to the edge/corner. If I set the touchpad speed too low, the small movements require multiple swipes. I want to lower the acceleration to match it with the "precision touchpad" of Windows, which is perfect (or disable acceleration if acceleration can't be lowered).

The disk (not by partition-level, but the whole disk itself) is encrypted using VeraCrypt. The partition I stored the files is using Btrfs. What is the way? Here are the things I have tried on my own: First, the web search result said Then, I tried to use the "Check filesystem" context menu on the volume of the VeraCrypt. But it showed an "fsck" window saying "If you wish to check the consistency of a BTRFS filesystem or repair a damaged filesystem, see btrfs(8) subcommand 'check'" and exited.
