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’ve been considering upgrading from my gaming laptop (intel/nvidia) with a secondary monitor to a monstrously specced out Thelio Major with a Ryzen 9 and RX7900. I have more money than time to build, I like the idea of coreboot and supporting system 76 as a company.
I’ve dealt with a slew of multi monitor issues already and my big hope for this new machine (aside from it being a gaming rig with some longevity spec wise) was that most of these display issues would be a thing of the past.
Reading this has me feeling a little crestfallen. Is this what I should expect from newer team red components? I usually run EndeavourOS and would probably install it before even booting Pop! which I’ve used and don’t really care for.
