Comment 10 for bug 346310

I think I found what's causing my problem: npviewer.bin.

I've tried suspending several times in a row, and every time npviewer was left running in the background, Xorg woke up using 100% CPU, and thus ignored all keyboard and mouse input.

If npviewer was killed before suspending, it seems to work all right. I'll try to do some more tests but, if I'm right about this, all I have to do is kill npviewer on suspend.
