Comment 47 for bug 28326

I just hit this bug on my 945GM-equipped macbook. On return from sleep I instantly get the evil behaviour described in the initial report. Similar Xorg log:

Could not init font path element /usr/share/fonts/X11/TTF/, removing from list!
Could not init font path element /usr/share/fonts/X11/OTF, removing from list!
Could not init font path element /usr/share/fonts/X11/CID/, removing from list!

...go to sleep here...
