Bushtech had a bit of a problem yesterday which we seem to have resolved with a bit of hacking. Thought I'd post the details here in case it helps anyone else or... if anyone can shed light on why it occurred.

Firstly, due to him running out of space on his root file system, his core froze and after a lot of messing about, he decided to re-install.

He did a clean install from iso image. First reboot brought black screen with cursor hanging (I think) at which point he dropped into command line and did an apt-get update; apt-get upgrade; reboot.
This time it came up with "Failed to start X". messages seemed to indicate that the correct nvidia drivers and alsa backports had been successfully installed.

We tried a lot of stuff- many deletes of xorg.conf and reboots with no luck. In the end, we tried a direct "startx" from the command line. This produced the following:
Code: [Select]

We focussed on the critical error - couldn't open rules file /usr/share/X11/kxb/rules/evdev. Confirmed that the folder(s) file(s) didn't exist at all and managed to track down the package that provides them- xkb-data. Package was already installed but folders/files not there so we did a

Code: [Select]
apt-get install --reinstall xkb-data
After which the folders were created, startx worked and took him to kde... a reboot brought up avwiz with badly sized but usable screen.

Not sure what happened but hope this helps someone else who hits the same issue or is trying to figure out the problems.

bushtech - can you post your nvidia card details?

ta.
