[Bug 276237] Re: compiz hangs X server on startup
Thanks for reporting the issue. When the hang happens, if you are able
to ssh into the computer from another machine or if you can switch to a
TTY with Control-Alt-F1, you could help us find the cause. ssh might be
more helpful than the TTY route though.
After starting compiz, waiting until it hangs X, and sshing in or
switching to a TTY, what does the "top" command show you? Is compiz
using a lot of CPU? If so, a compiz backtrace (while it is running)
would be really helpful.
To get a backtrace, first have a look at this page to add the repository for debug packages:
After adding the repository mentioned there, in synaptic hit "reload"
and search for "compiz". When you see the results, for each already
installed package there, install the corresponding -dbgsym package if
there is one.
Here, I have a script to get a compiz backtrace:
After downloading the script, starting compiz, waiting until it hangs X, and sshing in or switching to TTY, you can run the script as follows:
The script should write the name of the backtrace file it dumps.
