Hi,

I'm currently running Ubuntu 10.10 on our lab computer. The system was working fine until a labmate tried to install updates (he wasn't super clear on what he did... can't seem to figure it out), since then it's had a string of issues with gdm. I managed to uninstall the nouveau drivers and replace with the proprietary drivers for my graphics card, which is what everything was working smoothly in. I come back 2 days later, and now I can't launch gdm anymore.

When I do sudo /etc/init.d/gdm start

I get


Rejected send message, 1 matched rules; type="method_call", sender=":1.21" (uid=1000 pid=3236 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))

Can someone help? I've tried uninstalling and reinstalling this driver and the nouveau driver and had no luck... I tried to run apt-get update and --fix-missing

and no luck..... =/

Any thoughts/ideas?

As soon an you login to root in single-user mode, issue command
to see if there's an xorg.conf.back file, if so
if no xorg.conf.back you'll have to create 1.

I had to create an xorg.conf files... no problem loading gdm after I installed after that.


But when I rebooted the computer, boom, same stuff all over again. :/


Help?

I had similar problem with debian wheezy, solution was to execute tis command and reboot.

If you're not dual-booting, press "ESC" on power-up to enter Grub menu, select "Rescue Mode", run XFIX. This has corrected a lot of errors with Ubuntu for me in the past, from failed updates to swapping HDD into a different PC.
