Alt+Ctrl+F1 restarts x server

pjeeanah · 02-08-2010, 01:15 AM

I installed latest stable debian lenny. However when I want to switch to a virtual console by pressing Alt+Ctrl+F(1-6) the X server is restarted and I get the gdm login screen. When I kill gdm, virtual console switching works fine.

How to switch a to a terminal and return to my X session by pressing Alt+Ctrl+F7?

What happens if you are in a terminal emulator in x and as root run:

Code:

chvt 1

Warning, since Ctrl-Alt-F1 should be the same as this, it may crash your xserver.

After trying to switch to a virtual console and crashing/restarting X, what is in /var/log/Xorg.0.log.old?

/etc/inittab:

set initdefault to 3 and run startx, or edit to make sure consoles run on 2-6 while the X server runs on 1. I use the former method as I prefer the old fashioned consoles to xterms and don't always need X anyhow.

On Debian run levels 2 through 5 are the same, and 2 is the default.

chvt 1 restarts the X server. When I run xev to capture the keyboard, the X server is again restarted.

Puzzles me. Does it have something to do with gdm?

The log tells: caught signal 11

If you want to be without gdm in Ubuntu / Debian :

Ubuntu uses the Debian model, and the default runlevel is 2, unless
otherwise configured - so init 3 won't help, I'm afraid, unless you
enjoy reconfiguring runlevels .

If you have the file /etc/X11/default-display-manager you can edit it or
do

echo "false" | sudo tee /etc/X11/default-display-manager

This will disable gdm/kdm/xdm , or whatever you have in that file

You can put it back with a text editor, or do for example

echo "/usr/sbin/gdm" | sudo tee /etc/X11/default-display-manager

Of course, for a temporary disabling of X you can just do

sudo /etc/init.d/gdm stop then use the "restart" option or the
"start" option of that init.d script to restart it.

Short : open a terminal, do
echo "false" | sudo tee /etc/X11/default-display-manager

Back to work today evo2. I am attaching the Xorg log.

Perhaps you could find the offender.

Thanks

Seems to be a real bug. Looks like it could be related to:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=523529

If it is not the same as the above, you should probably report it.

It's definitely bad, and shouldn't be happening. But you shouldn't be in many of the places you are. A few thoughts.

There's a lot of waffle about vesa in there. Vesa and dri are incompatible, and a widescreen (16:9 ratio) is a problem since the vesa modes are mainly 4:3. I would put in /etc/X11/xorg.conf these lines
DisplaySize 410 256
HorizSync 31.5-whatever
VertRefresh 50-whatever

I believe you can enable SSE because hardly any box these days doesn't do it. The sky won't fall in any harder for trying it.
