/var/log/gdm/:0.log looks interesting. While I've attached the whole log, notice the following:
FATAL: Module mach64 not found. [drm] failed to load kernel module "mach64" and Errors from xkbcomp are not fatal to the X server xkb_keycodes { include "xfree86+aliases(qwerty)" }; xkb_types { include "complete" }; xkb_compatibility { include "complete" }; xkb_symbols { include "pc(pc105)+us+level3(ralt_switch)" }; xkb_geometry { include "pc(pc105)" }; The XKEYBOARD keymap compiler (xkbcomp) reports: > Warning: Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols > Ignoring extra symbols Errors from xkbcomp are not fatal to the X server These last messages occurred while moving from installer step 3 to 4 (I had tail -f running against the log in a terminal). Then, as noted, when moving from 4 to 5, the screen went dark (and I never see 5, except under the strange circumstance described above). Note that the attached log has messages for two complete runs (start the system, run the install, restart X, run the install again). BTW, FWIW my selections were English, Toronto, US English. ** Attachment added: "/var/log/gdm/:0.log" http://librarian.launchpad.net/5666777/%3A0.log -- Herd1 LiveCD boots, but installer hangs after step 4 https://launchpad.net/bugs/78298 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
