It's different for each kernel driver. This works on Intel for me: sudo apt install drm-info sudo drm_info | grep bpc -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069741 Title: [amdgpu]

None of these seem to help fixing the problem, so I don't really know what to do. The only thing that comes to mind is to try to set max bpc to really low numbers to check if that is what causing the problem. Is there a way to get the current value of this variable via terminal? -- You received

You can find more amd64 debs in: https://kernel.ubuntu.com/mainline/v6.8.12/amd64/ https://kernel.ubuntu.com/mainline/v6.9.3/amd64/ And yes you can force a lower bandwidth signal with something as simple as: xrandr --output DVI-D-0 --set 'max bpc' 8 -- You received this bug notification

Well, it did not work. I heard that 6.8.9 should work, but there are no .deb files in the repository for amd64, so I'm not sure how do I install it. Also, you said about different color schemes, is there a way to use a lower-bit one? In case that causes the problem. -- You received this bug

Display cables matter a lot because they have to transmit gigabits per second and small imperfections can interrupt that randomly, leading to a temporarily black screen. The reason a cable might work on Windows but not Linux could be slightly different signalling, if for example Windows is using

But why would the cable be the reason if it works properly on windows? And I would like to change kernel if it fixes the problem, the thing is I'm kind of new to Linux so I don't get a lot of Linux related stuff, but I already can install packages and do other simple actions. -- You received

Since it involves installing a lot of packages repeatedly and you don't sound confident, I will no longer recommend trying other kernels. Other than that, I can only suggest trying a newer HDMI (or DVI?) cable. -- You received this bug notification because you are a member of Ubuntu Bugs, which

All kernels available in the repository (not really sure which though, that's what said in the guide at least) are 6.8.0.31 and 6.8.0.35 and both of them have this problem. Probably there is a way to install other kernels, though I'm unsure which version should I install, how do I do that and does

Thanks. The only message I can see that might be related is: kernel: amdgpu :03:00.0: amdgpu: Disabling VM faults because of PRT request! which some googling suggests is caused by the GPU being under load. Certainly Steam was running at the time. It might pay to try some older and newer
