Sometimes my entire screen will turn green requiring a reboot. This has happened while gaming but also while watching videos in browser. I’m trying out undervolting/underclocking using LACTL. Have you experienced this? What was the cause and how did you fix it?
Please excuse me dropping off the face of the Earth for a couple days.

I’d suspect power issue, either cpu and/or gpu causing a spike that results in some voltage rail to go unstable. More likely GPU, unless your applications are really thrashing all cpu cores.
How old PSU? how much headroom? how good brand of PSU? Might also be a motherboard power management issue.
Also - it might not hurt just to unplug and reseat every power cable.
Please excuse me dropping off the face of the Earth for a few days. Power supply is Corsair 750 W. Linux 6.14.6-109.bazzite.fc42.x86_64 AMD Ryzen 7 9700X (16) @ 5.58 GHz
That PSU sounds good enough to me.
Could be worth a motherboard firmware update?
and i would double check all the power cables.It looks ike mangohud is an application to monitor stuff. I’ve never used it but you could give that a go - see if you’re ever getting close to the 750W.
Thank you for your reply! I’ll check it out. I need to try remounting and double checking cables still, I’ve just been putting it on the back burner. Oddly enough I experience this problem much less often when using Gnome rather than KDE.
What is your:
- Kernel
- Linux-firmware
- Mesa
Versions?
Additionally, what does the kernel logs tell you when you get a green screen?
Not a 7900 but my 5900 does for sure.
Seems to be a common issue. Lots of posts point to the PSU as the issue. Do a search on your card and green screen + linux and see all the results. Good luck.
