two sequential login windows after resuming from sleep

[Sander Jonkers]

After resuming from sleep, I sometimes (about 50%) get a first (unusual, ugly) login screen, then a short (<1 sec) flash showing my desktop, then the 'normal' login screen

First login window: http://oi59.tinypic.com/ws5uo9.jpg
Second login window: http://oi57.tinypic.com/24xnx4w.jpg

I tried the 4 sudo commands from http://ubuntuforums.org/showthread.php?t=1867733&p=11626298#post11626298, but that did not update anything, so I expect that to change nothing.

Then, based on http://ubuntuforums.org/showthread.php?t=1867733&page=3&p=12566826#post12566826, I installed and selected gdm instead of lightdm. I'll post back the results after a few days of usage.

Update:

After installing gdm (instead of lightdm) the problem did not occur anymore.

So: the problem seems to be in lightdm.
