I’ve just downloaded Manjaro for the first time having just moved over from Ubuntu. I’m liking it so far but am encountering a problem, that despite searching and trying multiple answers from the forum I cannot seem to debug.
I’m currently facing an issue when every 2-3 minutes, or when doing certain actions like scrolling in windows or swapping between them, the screen will tear (not exactly tearing but it’s the closest approximation I have). It’s slightly static-like also, however only in a horizontal section of the screen and never across the whole screen.
I had a very similar problem when I first installed Ubuntu 21.04, which was fixed upon switching to the LTS version. I’ve tried the same thing with Manjaro however the problem persists.
For hardware, I am running an i7-8700K CPU, and an AMD Radeon R9 390 GPU.
I have tried both proprietary and open-source drivers, neither of which fixes the issue. I have created a file as /etc/X11/xorg.conf.d/20-intel.conf, and tried adding:
If you haven’t messed with the compositor, try this.
Rename 20-intel.conf>20-intel.conf.bak
Reboot
On your desktop, just start typing “compositor” and krunner should take you to the compositor settings. If not, use the search within the system settings menu.
Try different compositors and or vsync settings.
Something will probably work. I haven’t tried it on AMD though.
I now have a video of the exact visual bug I’ve been dealing with. I haven’t been able to replicate it until now. For some reason, hovering over different games in my Steam library triggers the flickering effect.
Unfortunately, I can’t share the exact link to this video due to forum privileges. If to go to imgur and end the domain with /rzlGaDZ it should take you to it.
//EDIT: Also maybe try to force the use of the amdgpu driver (by using the package amdgpu-experimental or by using the same kind of modification this package does), if it can be compatible (maybe try directly or search).
UPDATE: It appears the card is supported by the AMDGPU driver, but considered “unreliable”. So if you want to try with the newer driver, as @omano alluded, you’d have to force it to ignore “radeon” and use “amdgpu”.
Thanks for the advice. Unfortunately, it’s resulting in the same issue as before; black screen on startup. I have to use the text console on boot and delete the file again to get the system to start normally.
I’ve tried all the settings in the compositor with no success sadly, and yes as far as I know the R9 390 should be a supported card still, although potentially unstable as you mention.
Still no solution as of yet. I’ve attempted various Xorg configs and none have worked (all result in a black screen on boot). Can’t seem to nail this issue down.
I’ve attempted running a few games to see if that exacerbates the issue and it indeed does, however is seems specific to the monitor I’m running the application on.
Also that seems weird that what works for everyone doesn’t for you, I would guess you’re doing something wrong. Share what you are doing, your config files, how you have configured the monitor, things like that.
Hey all. I cross-post this to Reddit and found a solution there. It seems like Shift+Alt+F12 solved the issue, which toggles the compositor. So it seems like I needed to toggle it on and off for it to work! Thanks for all your help thus far.
