I can confirm this bug in Karmic Koala. I've got a similar videocard, namely a 7800 GT based one: 01:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7800 GT] (rev a1)
My motherboard is the same too: ASUS A8N-SLI Deluxe The Ubuntu 9.10 final LiveCD won't boot with either default settings nor safe mode. With the default settings, before X starts, the graphical output is fine. When X starts, the screen is filled with seemingly random coloured dots. In safe mode, when X gets started no graphical output is seen whatsoever. But, more annoyingly, the non-graphical screen keeps flashing (text gone and back and gone and back...), and while the text output is gone, characters typed don't appear to get through to the system. Meaning that you basically can't type anything meaningful: I tried to start creating a /etc/X11/xorg.conf file, but only 1 out of 30 characters typed appeared on the screen. The only useful thing I could do was reboot. -- Corrupt graphics on boot with 7800GT/nv https://bugs.launchpad.net/bugs/62230 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
