 |
|
Hi.
Yesterday my desktop got frozen, so I had to use hard reset button, and now I can't boot into my KDE. xorg doesn't start. When I trying to startx manually X fails with the following message: parse_vt_settings cannot open /dev/tty0 (permission denied)
I read that it may be suid issue, but I can't startx neither as user nor as root. I tried to rebuild xorg-server with suid - no dice (built it back to -suid). As well I tried to rebuild nvidia driver (390.141 here). Still can't boot into DE.
My Xorg.0.log
and dmesg
dbus and elogind are started and running.
Any idea? Why it refuses to start?

In order to avoid the dreaded hard shutdown in case of freezzes and kernel panics
ALWAYS
have
| Code: |
sysrq_always_enabled=1 panic=20
|
in Linux line in /etc/default/grub.
Then when something like this happens you just press
| Code: |
RIGHT-ALT+PRT_SC+REISUB
|
and you get it rebooting.
In case of kernel panic during boot it will auto reboot after 20 secs.
As for the rest [lease see

Solved by updating kernel and rebuilding nvidia driver against new kernel
