I was having this flickering screen on the TTY1 prompt problem. My fix for a Dell E1750 with an ATI Mobility Radeon X1400 Card:
(ssh into the machine if possible, or boot in recovery mode) su - service stop gdm apt-get remove xorg-driver-fglrx xserver-xorg-video-radeon xserver-xorg-video-ati apt-get autoremove apt-get install xserver-xorg-video-radeon xserver-xorg-video-ati libdrm-radeon1 Xorg -configure cp /root/xorg.conf.new /etc/X11/xorg.conf init 6 This will blast your current xorg.conf away. Sorry. Back it up if you're sentimental. The big problem I had, besides the initial graphics floundering, was that when the xserver-xorg-video-radeon package was installed, it didn't install libdrm-radeon1. This caused Xorg -configure to spit out a nasty segfault. -- upgrade breaks graphic drivers and x, preventing login or startx https://bugs.launchpad.net/bugs/464591 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
