Hi!
I’m having issues with both Kubuntu and Ubuntu. I backed up my windows 10 install and then installed Kubuntu 24.04.2 LTS via usb without any issues, erasing the windows installation on the disk. Started getting everything updated and software installed (Synergy, VPN, etc). No issues at first and then all of a sudden after about 45 minutes the system freezes. Upon reboot I get a handful of error messages before the system fully boots.
DMAR: DRHD: handling fault status reg 3
DMAR: DRHD: [DMA Read NO_PASID] request device [02:00.0] fault addr 0xc0177000 [fault reason 0x0c] non-zero reserved fields in PTE
Then when the reboot finishes I’m able to login but past the login screen the desktop environment is graphically bugged with like a checkerboard pattern. I can access apps and the terminal but trying to actually read anything a nightmare. Moving the mouse over windows sometimes reveals text, but sometimes doesn’t. Attempting to take screenshots has yielded mixed results so I actually took a picture of the display. Some of the those lines are damage to the monitor, ignore that. I tried reinstalling using the same install media, but the same thing happened. Fine for a little bit, then crash and graphical issues on reboot. Then I tried installing regular Ubuntu 24.04.2 LTS. That didn’t make it through to the first crash, immediate graphical issues. So I switched back to Kubuntu but tried using a new USB drive and new ISO created with balena etcher instead of Ventoy. That lasted a bit longer, maybe an hour, but I’ve ended up in the same spot.
