I messed something up w/xorg config - can live boot in...

[jzacsh]

after a reboot one day my resolution was set to oddly low, so i was trying to fix it. i found this post on changing screen resolution (http://ubuntuforums.org/showthread.php?t=83973):
http://ubuntuforums.org/showthread.php?t=83973


after a brief (apparently, too brief) look at that post ^ I ran:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
/etc/init.d/gdm restart


this caused my screen to go black immediately. I rebooted the computer (forced shutdown), than when I got to GRUB and selected the Ubuntu install (two drives in this tower: one w/xp, one w/ub), the screen goes black and never does anything - nothing happens.

I tried this IRC #ubuntu channel (http://irclogs.ubuntu.com/2009/09/10/%23ubuntu.html) (ctrl+F my handle "jzacsh" on that page to see). someone said it doesn't sound like the command i ran could've caused this. then it was suggested I try:

chroot into the troubled install while booted w/a LiveCD,

sudo dpkg-reconfigure xserver-xorg


i did successfully chroot in and ran the command successfully w/no errors. unfortunately, it doesn't solve the problem.

anybody have any ideas? this drive has a development server on it w/a lot of work that i'd hate to have to reconfigure/install.

let me know if i'm posting this in the wrong forum (maybe I should be putting this in Multimedia and Video (http://ubuntuforums.org/forumdisplay.php?f=334))

purge and reinstall the X
:)

purge and reinstall the X
:)
oh,okay thanks. so.... would this be right?

sudo apt-get uninstall xorg

[jzacsh]

anyone?

[jzacsh]

oh,okay thanks. so.... would this be right?

sudo apt-get uninstall xorg

for anyone else coming by - I believe its:

sudo apt-get purge x
i'm assuming x, because it was just suggested to me, so I'm taking it literally - i don't know if "x" includes xorg? if xorg has little to do with this... but i'll post here when i fix the problem.

okay, trying to purge x didn't work. so i purged exactly what i originally posted about: xserver-xorg, like so:

sudo apt-get purge xserver-xorg
after of course booting from a LiveCD, and mounting the troublesome drive, then:
sudo chroot /media/disk (disk being what my drive mounted as)

* i've also been ignoring all the errors about /dev/null (because, i guess i don' know how to use chroot to allow fstab to work right?)

I'll see now how installing goes...

Thread moved to Desktop Environments at OP request :)

so purging and reinstalling xserv-xorg didn't do the job.
anymore ideas?? to have to reinstall my development server is really going to.... well, push back development. any more help at all?
