tested with Ubuntu natty if I boot the live session and wait for gdm starts, the only graphical display I have is white and black horizontal static lines.
after a few seconds, the computer totally freezes. As soon as GDM is started, I must quickly switch to the first terminal (ALT+F1) before the computer freezes, now, i've the time to work, the computer will not freeze anymore. once here, i can create an xorg.conf file to properly restart gdm, here is the xorg.conf created file (from my remember, maybe I've made typo mistakes since I'm not near the computer anymore) : ##### --- /etc/X11/xorg.conf --- #### Section "Device" Identifier "card" Driver "nouveau" Option "NoAccell" EndSection Section "Monitor" Identifier "monitor" Option "DPMS" EndSection Section "Screen" Identifier "screen" Device "card" Monitor "monitor" defaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubsection EndSection Section "ServerLayout" Identifier "serverlayout" Screen "screen" EndSection ##### --- END /etc/X11/xorg.conf --- #### once this file is created, i can kill all "X" existing session by a kill -9 and make a start gdm (don't know why the "stop gdm" command does not kill "X") now, I've a functionnal live session and I can install ubuntu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/820461 Title: graphical issues with nvidia Geforce4 ti4200 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/820461/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
