Try New Technology

If you are using Flatpaks on Manjaro KDE (probably any distro you use flatpaks on) and switch from an NVIDIA to AMD GPU in the system you will need to search through the install flatpaks to find all any NVIDIA drivers that are bundled. On my system I found that Protontricks, Heroic Game Launcher, and Wine (WineHQ) will still have NVIDIA drivers installed and will need to be removed manually.

• From Konsole run: sudo flatpak list | grep nvidia
• Then you can run: sudo flatpak uninstall [PACKAGE] (do this each time for all the entries found with the list flag.

NOTE: Using Flatpak

inxi -Fza


-F, --full
Show Full output for inxi. Includes all Upper Case line letters except -W, plus -s and -n. Does not show extra verbose options such as -d -f -i -l -m -o -p -r -t -u -x unless you use those arguments in the command, e.g.: inxi -Frmxx

-a, --admin
Admin options are advanced output options, and are more technical, and mostly of interest to system administrators or other machine admins.

Grim Dawn (w/ all DL)C, I was seeing some screen tearing in the upper 1/8 of the screen and the background seemed to stutter even though FPS was solid. The following changes were needed on my setup to resolve this. Posting here and on ProtonDB – Game Details for Grim Dawn in hopes this helps someone else.

Changed desktop from 60Ghz to 120Hz (monitor can do 144Hz)
Edit the games options.txt file at “~/.local/share/Steam/steamapps/compatdata/219990/pfx/drive_c/users/steamuser/Documents/My Games/Grim Dawn/Settings/“:

UPnPEnable = false
forceSingleProcessorMode = false
maxResourceThreads = 8

NOTE: maxResourceThreads should be equal to the number of cores (not threads) the CPU has; default is 1.

Steam Properties >
Launch Options: Play Grim Dawn (x64)
Advanced: RADV_PERFTEST=aco gamemoderun %command%

Compatibility > Force to Using GE-Proton7-55

NOTE: Many have reported random black screen issues unless using “RADV_PERFTEST=aco”

In game I have everything cranked up to max and all options in video turned on (including VSYNC) and Refresh set to 120Hz also.

When doing a “sudo pacman -Syyu” from the terminal on Manjaro (KDE) and you get something like “…signature from Mark Wagie is invalid…(invalid or corrupted package (PGP signature))” then you may need to run an update to import the latest Manjaro keys with the following command “sudo pacman-key –populate manjaro”

If you need to rollback the kernel version within Manjaro KDE, then on boot up tap the “SHIFT” button and you will get the grub menu. Select the Advanced option and then pick the kernel you want to boot to.

NOTE: This was helpful after accessing and interacting with file (rename, opening, etc) started getting laggy and would “pause” after going from Linux 6.1.22-1 (LTS) to Linux 6.2.9-1
