Weird error: display and crtc error

Hello,

Just like every day, I turned on my Debian Squeeze machine this
morning. While I don't think I asked for upgrade yesterday, it appears
something has changed in the system.

The X server won't boot. In place, after all the booting process,
I'm left with many
==
[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc
f5fec000
[drm] nouveau :01:000: no space while disconnecting DAC
[drm] nouveau :01:000: no space while hiding cursor
[drm] nouveau :01:000: no space while blanking crtc
==

As the X server does not start, I booted in recovery mode (X server
does not start neither). Anyway, I checked the Xorg log in recovery mode,
which contains, at the end:

==
(EE) NOUVEAU(0): failed to set mode: Invalid agument
==

Typing startx or xinit results in (after traditional messages):

==
sh: /usr/bin/xkbcomp: not found
(EE) Error compiling keymap (server-0)
(EE) XKB: Couldn't compile keymap
XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect
setup of xkeyboard-config.

Fatal server error:
Failed to activate core devices.

xinit: No such file or directory (errno 2): unable to connect to X
server
xinit: No such process (errno 3): Server error.
==

I therefore wanted to install x11-xkb-utils, which contains xkbcomp. However,
x11-xkb-utils is already installed. Therefore, xkbcomp should, but I
however get
==
# /usr/bin/xkbcomp
No such file or directory
==

I saw on various forums that 
==
[drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on crtc
f5fec000

was probably linked due to a lack of free disk space. However, df tells
me I've only used 23 % of capacity; there is still lot of free space for
/.

This could also be due to a permission problem, but /var/tmp and /tmp
permissions are OKAY (did a chmod 1777 meanwhile in order to be sure).

I tried with another kernel (being given GRUB choices), to no avail.

Removing x11-xkb-utils (in order to install it after) removes gnome,
gdm, etc., so I would prefer avoiding that (and I'm even not sure it
would solve the issue).

I also tried disconnecting the keyboard, but it changes nothing. I also
tried Xorg -configure then reboot, but that does not change anything.

Is there a solution to that problem?

Thanks.

Problem solved.

I solved the problem by reinstalling x11-xkb-utils; no harm to remove all the 
gdm  gnome stuff if reinstalled directly!
