I'm having very similar problem with Xubuntu 6.10 beta desktop-CD and Voodoo3 2000 agp - Xserver tries to start, but only gives a black screen with the standard X-shaped cursor in the middle of the screen. The cursor cannot be moved, and the system is totally unresponsive, requiring reboot.
No chance of actually installing the system and getting logs right now, but see the following upstream bug report pertaining to the tdfx driver version used also in Edgy beta: https://bugs.freedesktop.org/show_bug.cgi?id=7967 -- X doesn't launch with voodoo 5 5500 https://launchpad.net/bugs/63796 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
