Boot issues, tty accessible

Support
1

Hello,
when I started my PC today, I choose my usual kernel in GRUB and ended up with a blinking cursor - instead of the login screen. I tried all alternative boot-options, all leading to the same situation. Since this is not the first time this happened, I supsected the graphics driver (I use the non-free nvidia drivers). So I uninstalled them and installed video-vesa instead. Same result.

Below is my system info, including a journalctl-log that show some failures. Can you please help me to troubleshoot? I do not umderstand the journslctl output…

kernel 6.0 is EOL ( no more support ) as nvidia drivers for this kernel version
if possible add kernel 6.1 & 6.2

sudo mhwd-kernel -i linux61 
sudo mhwd-kernel -i linux62

reboot and remove kernel 6.0

sudo mhwd-kernel -r linux60

also you should use nvidia drivers ( current ) not nouveau

sudo mhwd -a pci nonfree 0300

you may need to add on boot
“iommu=pt”

and think about update your UEFI motherboard

Installing kernel 6.1 went smoorth. 6.2 gave some feedback about my win boot partitions and the unknown device type nvme0n1 (there is only 1 disk in my pc). To be on the safe side, here is a screenshot.

After installing the kernel, I boot into 6.2.9-1 (still not GUI) and remove kernel 6.0.

Inan attempt to install nvidia ends like this:

I do not understand what to do with this iommu=pt. Could you pls elaborate?

Is this what you suggest?

so you will have to remove kernel EOL ( end of Life – no more support )

sudo mhwd-kernel -r linux519 
sudo mhwd-kernel -r linux60

boot on kernel 5.15

sudo mhwd-kernel -i linux61
sudo mhwd-kernel -i linux62

check after if some file ghosts stays ( keep only linux 515 , 6.1 and 6.2 )

for iommu=pt see this

I have now installed the kernels you recommended. All other kernels are removed.

The symlinks seem ok:

I’d rather get your confirmation, before srewing up my grub:would this be ok?

Rebooting => same situation.

Attempting to install nvidia-drivers, it refuses to do so because of to files: one is related to wayeland, one to the nvidia/utils. I move them by adding “.bak” to the filename, and restart the installation. During installation, the screen turns black, and I eventually have to perform a hard shutdown. However, afterwards the GUI starts, pretending nothing happened.

Thank you very much for zour support, Stephane. Though I have backups in place, the thought of having to reinstall everything and download 2TB of data from backup… ouch…

did you removed the vesa config? post output from:
find /etc/X11/ -name "*.conf"

(base) [dejhost@Workstation ~]$ find /etc/X11/ -name "*.conf"
/etc/X11/mhwd.d/nvidia.conf
/etc/X11/mhwd.d/vesa.conf
/etc/X11/xorg.conf.d/90-mhwd.conf
/etc/X11/xorg.conf.d/00-keyboard.conf

Should I remove the vesa.conf?

11

yes remove the conf, but first check with:
mhwd -li
and only video nvidia should be listed, if you still have video vesa remove it…
