[Bug 1409099] [NEW] after suspend xorg uses very much CPU.

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

After I've had my laptop suspended it got really slow - and it's brand
new and not as slow after fresh boot.

I saw that the xorg process used almost 100% of the CPU. After I've
restarted compiz it got lowered, so it actually might be that instead,
and not the xorg packade.
