Bug#770660: mate-screensaver: resume from suspend fails in certain circumstances

[tony mancill]

Package: mate-screensaver
Version: 1.8.1-1
Severity: normal

Dear Maintainer,

This could be considered minor, but it is reproducible and slightly
annoying.  To reproduce:

1) Suspend the laptop while docked in a docking station (with
   multiple monitors, if that makes a difference).

2) Eject the laptop from the docking station and resume the laptop.

3) The X display will be hung and no unlock mechanism is visible until
   switching to a Linux console (Ctrl-Alt-F1) and killing the 
   /usr/lib/mate-screensaver-gl-helper process.  At this point,
   switching back to console 7 displays the expected lock dialog.

Some other windows managers can handle this - it would great if the MATE
environment didn't get confused.  If it makes a difference, the laptop
has an Intel HD 4000 chipset.

Thank you,
tony
