Public bug reported:
Binary package hint: nvidia-glx
I have a geforce FX5200 and a 19" 1280x1024 DVI LCD monitor.
I experienced this behavior in gutsy's liveCDs, tribe 1 to 3. I guess
that if it's still not fixed, nobody must have noticed.
Starting the liveCD in "normal mode" will get me to GDM but the X session will
never start.
The TTYs do not allow me to login to use them and diagnose the problem (this is
the most frustrating part: I can't provide debug info to you).
Starting the liveCD in "failsafe graphics mode" will sometimes (one out
of four times maybe) get me fully logged into a functional desktop. The
3 other times, I will get the computer in an unusable "hung" state,
meaning that it stops logging in either after hearing the login sound,
after seeing the splash, or the panel, or nothing at all except the
beige background and the mouse cursor.
The mouse can always move but I cannot interact with anything in the gui.
The TTYs are still frozen.
The only thing that can respond is the magic system request keys
(alt+sysrq+s/u/b).
I checked my ISOs and my CDs. And these liveCDs work 100% correctly with
my intel-based laptop (they work exceedingly well).
My only hypothesis for the "normal session" would be that it tries
starting compiz-fusion while using the "nv" driver. I cannot explain why
the "failsafe graphics mode" can hang and I sometimes need multiple
boots to make it work, looks like a race condition of some kind (but
then, I never saw this in previous ubuntu releases). What the? Please
enlighten me!
