Public bug reported:
Binary package hint: firefox-3.5
Hi,
By default, I had compiz "Visual Effects" = "Normal" selected
(through Jaunty).
When I updated to Karmic, when I would try to start Firefox (or
several other applications), my T41 (actually, two of three units)
would hang with a mostly translucent trapezoid. No mouse/key
press had any effect on anything. I had to power down.
I have three T41s running and experienced this on two of the
three. The third did not suffer this anomoly. I discovered the
only difference was that the working T41 had compiz "Visual
Effects" set to "None".
When I switched the other two to "None", things worked fine.
I am running "/usr/bin/metacity --replace" and getting splendid
response on my machine (with "Visual Effects" = "None").
Later, on one of the T41s, setting gconf-editor->apps->metacity
select compositing_manager ON yielded terrible performace
(for Firefox), but it did not crash. Running with compositing_manager
OFF, things are great.
FWIW, under Intrepid/Jaunty, compiz effects worked but
with karmic, it seems to push the capabilities a bit too hard,
and ends up freezing.
Perhaps the classification of what is discovered in the hardware
is over-estimating the capabilities of the machine somewhat.
NOTE: When karmic+compiz fails, what happens when I
try starting Firefox (for example), a trapezoid shape (small
side on bottom) is slightly visible (like the frame is flipping
down to vertical) but all (mouse/keyboard have no effect on
the cursor or selection of virtual terminal ctl-alt-F#). Only
a power down works.
