System spec - Ryzen 3700X CPU - AMD RX 7900 XT GPU
I got an AMD GPU specifically because I wanted to switch to Linux. I’ve done a bunch of testing over the last year while I still had an nVidia card. Now I’ve got an AMD GPU I feel ready but it has not gone well.
When I use multiple monitors I get a range of odd behaviours, including a white screen, lock ups, failure to display anything on second screen. I’ve unplugged the second screen for now and all is OK except that adaptive sync does not work properly.
When I set adaptive sync to “Always” in the settings the screen sort of flickers when I move the mouse. To be more precise the screen gets a bit brighter when the mouse is moved, then returns to previous slightly dimmer brightness when the mouse is stopped. There are no errors that I’ve found.
Both of those issues happen in fresh Fedora 38 and Arch Linux installs. I’m running KDE-plasma (using Wayland not X) so it seems like a KDE issue. Though I’m about to test it with a Fedora and gnome install next, though I doubt it will be any different.
I have the same gpu (and intel 8700K)
I got audi running to my monitor which then sends it to my speakers, in mint its stuttering and tertible, but smooth as silk on windows.
It runs fine though, in terms of games (only tested CSGO though) in 144hz. Not entirely sure about other features (freesync etc)
I had to update the kernel to get multi monitor and proper resolutions to work
I’d like to explore messing with custom kernels but I’ve got a bunch to learn first. In the mean time it kinda feels like I’m stuck with no straight forward or standard way to ensure multiple monitors works at least. I’ve spent 2 days on this and still found no answer so I’m hoping someone will post a helpful hint or 2.
