I forgot about split_lock_detect=off …I think that fixed the crashing problem, I didn’t use it before because there was no need, everything worked, as soon as my system updated to 6.14.2 it started crashing, it’s why I went on my wild quest of testing to try to resolve it, the weird one was Bazzite, since they stuck with an older Kernel, but it still was crashing, but that might have been already an issue with that OS.
Anyway I tested a bunch of steam games played them all for a while 30min+ no crashing, will keep testing to be sure and re-connect second monitor.
UPDATE: At least 1 game still locks up… FFXIV and im not sure why, the rest of the 15+ games I tried run perfectly.
I figured out something, games ignoring the screen that is set to primary appears to be a wayland issue…
I was messing around on Linux Mint and it’s still using X11 and games perfectly launch on the correct screen, the one set to primary, I decide to switch to wayland, and now I keep having this issue again, the screen thats set to primary is ignored and games always launch on the opposite screen… until I force it with xrandr in the terminal.
Cool, im on the 6.15RC3-1 kernel, I assume it’s not in that version but good to know.
I switched to cachyOS to try to resolve crashing issues and the monitor issue and so far it’s been perfect using Wayland, 6.15RC3-1 kernel and MESA 25.0.5. Can’t wait to try FSR4 finally.
For various compatibility reasons with other packages, I have vanilla Ubuntu 25 on my 9950X3D - 9070 XT machine. As of mid-May 2025, the kernel is 6.14.0-15-generic and mesa-common-dev 25.0.3 comes preinstalled, which is higher than what Wendell suggested in the first post.
Just out of curiosity, what tests could I run to see if the features of the 9070xt work as expected?
(I game on this machine on a Win dual boot; Ubuntu is my work OS on this box. Also, insert pages of rants about how Ubuntu’s Gnome is horrible/terrible/bad-bad-bad.)
Well, that’s one reason to install and start playing it.
