Only when I manually boot to the 6.14 kernel is the GPU operational.

root@proxmox:~# uname -r
6.8.12-11-pve

you are not using proxmox-boot-tool to manage the ESP (which is okay) - the kernel should be picked up automatically..

could you run

Code:
update-grub

and post the output here?

so it does add an entry, if you reboot you should boot into the new kernel.. do you get an error?
 
I restarted Proxmox via the web interface and added the log starting from “-- Reboot --”. I do see some errors, but they’re not related to not using kernel 6.14, are they?

could you post the generated grub.cfg?
 
and you /etc/default/grub ?
 
yeah, your /etc/default/grub contains a boot entry pinning.. (GRUB_DEFAULT=..). set that to "0" and re-run update-grub, then your system should boot the newest kernel..
 
Dear Fabian,

Thank you for your help. I use the Proxmox as a hobby to frigate three cheap security cameras. The minimum price of €115 is too expensive for me. Does that mean I can't ask any more questions?

Best regards,
Freek
 
Note that that price is also before taxes but does not get you any support tickets. Feel free to ask questions on this forum regardless. Most people here are volunteers and there is no guarantee that Proxmox staff will answer your particular question. Then again, there are some very knowledgeable people here that have used Proxmox is all kinds of ways, from who I still learn every day.
