I can confirm this, and have found a workaround I get a major screen corruption in either step 4 or 5 of the installer, a ctrl-alt-backspace lets me log back in to a normal desktop without having to do a full reboot. I found that switching to a virtual terminal (ctrl-alt-f1 for example) and switching back to the desktop (ctrl- alt-f7) gets me back to where I left off. I tested this about 6 times before going on to the partitioner and completing the install.
nothing in syslog or xorg log indicates anything out of the ordinary my video card is a GF FX5200 -- installer crashes in feisty https://launchpad.net/bugs/78437 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
