getting gpu logs from linux

[jalavoui]

getting gpu logs from linux requires a special boot flag

 

grub.efi sample config

 

set timeout=0
menuentry "Ubuntu" {
    set gfxpayload=keep
    search --no-floppy --fs-uuid --set=root 60c989ee-b27b-420d-8a17-b541c2605fb3
    linux    /vmlinuz root=UUID=60c989ee-b27b-420d-8a17-b541c2605fb3 ro  quiet splash drm.debug=0x14
    initrd    /initrd.img
}

I'd like to add that enabling verbose logging can produce a lot of data, so ensure you have a way to sift through the logs effectively. Tools like 'grep' are really invaluable for filtering through the noise to find the relevant information.

yes best way is get /var/log/syslog file

 

depending on the flags you get lots of log lines

 

idk where to find those debug flags
