Public bug reported:
I "upgraded" to Gutsy by doing a clean install a couple of days ago and now
have noticed a strange screen flickering bug.
I have a radeon mobility 9000 on a Dell Inspiron 600m, and did not have this
problem previously with Feisty Fawn.
The bug is screen flickering in text consoles _and_ X. Interestingly, though,
this bug does not occur if I boot into splash and then
it goes straight to X. I am able to log on and use desktop effects and such
without any flicker. However, the moment it has to
switch to a text tty/vt, whether through a Ctrl-Alt-Fn or after I log out when
X restarts, it starts flickering and the flicker makes
everything pretty much unusable (well quite annoying at least). I tried booting
with vga=normal but that doesn't change anything. No splash on boot doesn't
help.
I believe this has something to do with the new text tty changes in Gutsy vs
Feisty, but am not sure exactly what these are, so if someone has some advice
maybe on something I can do to try to mess with these that would be great (I'm
pretty sure it's not
an X issue per se b/c it does not seem to happen the first time X starts and I
log on after splash; oh yeah also it does _not_ happen when BIOS is starting
and in the initial splash; however after we go to tty I can't get the flicker
to stop).
Thanks a lot
Misha
