[intrepid] After apt-get upgrade, Desktop Effects Cause Blank Brown Screen On Boot

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in compiz.

I believe this is the same bug that I've run into when trying to run the intrepid alpha 2 liveCD on my laptop, which uses an i945GM chipset. When the livefs boots, the desktop background comes up, then everything goes blank. If I switch to VT1, I see that compiz.real is running; if I kill it and switch back to VT7, the desktop appears (sans window manager, of course). Starting metacity in its place, everything works fine.

I have an issue with similar symptoms under VMware, but I'm not able to determine whether it's the same cause since it's not possible to switch VTs under those conditions.

Marked as high-importance and milestoned for alpha-2, since others in #ubuntu-testing are reporting similar problems, and this appears to be preventing any of the available testers to get a good desktop install test for the alpha.

i think this might be a duplicate of #245888

https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/245888

Yep, seems to be te same :-/ Just better well defined :-)

Can these be merged?

I've discussed this bug with Bryce Harrington on IRC, he doesn't see that there's evidence to think this is the same as bug #245823 (brown screen is not the same as a white or black screen). I've unmerged the reports.

haha, well, browny-beige, i could see it being mistaken for white, but not black.

Can't really take a screenshot of it though :-s

Here is the console output captured by starting compiz from a terminal (after doing the kill-compiz-and-start-metacity dance):

I'm unable to get a backtrace from compiz or gtk-window-decorator; attaching to either of these processes in the liveCD environment using gdb just gives me an indefinite hang until I kill gdb.

That is the white screen mesa bug. If it is showing brown for you that is very confusing but it is the same output from compiz.

here is my output (with intel i810 driver):

compiz starts and runs as usual...

the difference is in FBConfig.... whatever that means...

Same happens in my laptop Acer aspire 1644Wlmi. My output with intel i910 driver

So either this bug is a dupe of bug 245888 or all of you are seeing bug 245888 and the original reporter has a different problem. tenof, can you see if you get similar output from compiz?

okay, erm, im hoping im doing this right, i typed

compiz --replace like everyone else seems to, and heres my terminal output:

hope it helps, and if there is anything else i can do / obtain, then do let me know :-S

Ok, I'm not sure why you see brown and the other bug has white but I'm 99% sure they are the same bug. In either case, they are both not compiz problems but mesa problems.

The screen may appear brown if the backlight is dimmed - at full brightness it would be white.

I sometimes get white screens if a window is created while I'm on another desktop. I can minimize and restore from taskbar to make it go away.

I think the brown screen is because the gnome-session isn't starting.
