I've no idea why, I'd not done anything to the graphics, it just ... stopped being able to run at high resolutions over HDMI or VNC.
In the Monitor Preferences this is all that's listed, and this is weird, too, because the monitor is a 60Hz 1440p Benq. Previously everything was fine, I'd followed guidelines (I don't remember where from) after my install to have the following commands in GRUB to ensure that the driver loads with X or something, I don't know, I just know that it made the Radeon Vega 8 graphics do something ... then they seem to have stopped working on a recent restart (system crashed).
I see no errors, and the GRUB line appears to be still OK in the massive file:
Code: Select all
linux /vmlinuz-5.4.0-96-generic root=/dev/mapper/vgmint-root ro quiet splash nomodeset
EDIT - Apparently this is not a factor, also the gpu-manager.log indicates that it is not blacklisted, but that could mean nothing, I dunno.and something blacklists the amdgpu module from time to time, which must be un-blacklisted by editing /etc/modprobe.d/* to work
Could the installation / update of VNC / RDP services be to blame for fiddling with X?
Should I update to 20.3 Una, like this post?
