Try New Technology

Just dropping this here so I can refer back to it myself. From the console type in “sudo winetricks –self-update”

Mostly posting this here to help me keep track of the bug.

Looks like on AMD GPUs have and ongoing bug when you have a monitor using HDMI to connect to the onboard (iGPU) or add-in GPU, where the monitor going into “Input Scan” will causing the computer to wake back up the other monitors and they never turn off. There are some workarounds (none work for me), but ultimately it needs fixed or I need to get away from an HDMI connection to my secondary monitor.

Freedesktop.org’s gitlab issues tracker: HDMI connected monitors fail to sleep and instead turn back on when amdgpu.dc=1

SOLUTION (workaround): is to pickup a Display Port to DVI (computer to Monitor) adapter and stop using the HDMI input. In this case once the screens go to sleep the monitor will still go into an “Input Scan” mode, but when no other input is found the monitor will go back to DVI and go to sleep correctly. I was able to test this without waiting for the Monitor Sleep timer to be reached with the following command from the Konsole – “xset dpms force standby”

To turn off Desktop Effects (Desktop Compositing) in Manjaro KDE this can be done by making the following changes:

1. System Settings > Display and Monitor > Compositor
2. Uncheck “Enable compositor on startup”
3. System Settings > Shortcuts > Shortcuts > KWin (Under System Settings)
4. Click on “Suspend Compositing:” and uncheck the box next to “Alt+Shift+F12”
5. Click Apply
6. Reboot

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.
