[SOLVED] Ctrl+Alt+F1...6 freezes desktop and unable to get to console

rdav · 2024-12-06 07:28:34

Hi All,

Can you please help with this annoying problemo?

ctrl+alt+f1/2/3/4/5/6 freeze the desktop and the only way to recover is to ssh in and reboot from there.
or ctrl+alt+sys+REISUB to reboot.

I thought it may be the framebuffer resolution in /etc/default/grub.
As in the value for "GRUB_GFXMODE"
However values listed in "hwinfo --framebuffer"
1920x1080, 1600x1200, 1280x1024, 1280x800, 1024x768, 800x600 have no difference and ctrl+alt+f1 freezes the desktop

Unsure how to tackle this.

FYI: /etc/default/grub:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

GRUB_SAVEDEFAULT=true
GRUB_DEFAULT=saved

does it wake up with ctrl-alt-7 ?

if so, which init system do you use? and does it start getty on tty1-6 ?

stargate-sg1-cheyenne-mtn · 2024-12-06 08:23:16

what does "who -a" display?

blackhole · 2024-12-06 12:22:41

First, as part of a process of elimination:

GRUB_GFXMODE=800x600
GRUB_GFXPAYLOAD_LINUX=keep

Comment those two lines, then:

# update-grub

Reboot

If that changes nothing, revert the change and run "update-grub" again.

At that point, the problem is most likely related to the Nouveau driver.

The driver has "power management" listed as "WIP" for NVE0 here:

https://nouveau.freedesktop.org/FeatureMatrix.html

So with a laptop ,you may be better off abandoning the attempt and pursue trying to get the nvidia proprietary driver installed and working instead.

Thanks to all who responded!

ralph.ronnquist: no change on crtl-alt-7, still locked up, still have to use ssh in and reboot from there

blackhole: that fixed it!
removing

GRUB_GFXMODE=800x600
GRUB_GFXPAYLOAD_LINUX=keep

and updating grub, rebooting sorted it out!

Thank you for all!!

blackhole · 2024-12-12 09:50:49

That's good to know. I believe those lines cause display problems with kernel mode setting drivers. With KMS you don't use that method to set the console resolution anymore. Instead you need to set the console font size.

rdav · 2024-12-12 10:27:26

I spoke too soon!

the switch to console with ctrl+alt+f12345 is unreliable and still freezes this laptop.

That's a separate issue. Unfortunately, as per my earlier post, you may have to install the nvidia proprietary driver. To get stable performance, and working power management.

No solution, just wondering: Does "Xwayland" mean something here?

Btw: Interesting inxi switches.
Respective line on my excalibur machine (with nvidia driver and 1920x1080 consoles) is:

rdav · 2024-12-13 04:33:27

blackhole: thanks nvidia drivers are now installed, and the ctrl-alt-f123456 keys are working again!

Note: last time I attempted nvidia drivers on this ancient laptop and gpu combo it didn't work.

This time followed the Debian notes to install the Nvidia drivers https://wiki.debian.org/NvidiaGraphicsD … dia-detect
After removing the previous xorf.conf for nouveau, restarting display manager (slim) the gui login screen came up.
With the consoles all cooperating!

thanks again!
