[Bug 969860] Re: fglrx uses 100% CPU when screen turns off (spinning in glXWaitVideoSyncSGI or glXSwapBuffers)

About the "Can't open ./dstack" error: you need to download the script
first. It's attached on comment #4.

> Also, how can I enter the command when the problem disappears as soon
as I unlock my machine?

Try this:

  sudo sh -c "sleep 5; sh $HOME/dstack compiz" >> compizstack.txt

Launch the command, immediately lock the screen and wait for 10 seconds,
then unlock the screen. This will dump the stack in the middle of the
screen lock.
