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. l...@bogus:~/FWSLC/Billing-Xylo$ lsb_release -a No LSB modules are available.
