Occasionally, when I recover from power save mode I get a black screen with just a cursor. I can't see the desktop or any applications but, according to ps, they are still running. I have to kill X to recover from this bug.
Currently, I am running KDE using GDM but it has happened to me previously using Unity and lightdm and Unity and gdm. I am running a two-monitor setup. One is connected via displayPort and the other is DVI.

Stephen Rasku, thank you for reporting this and helping make Ubuntu better. As per http://
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https:/
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.
Once the BIOS is updated, and the information above is provided, then please mark this report Status New.
Thank you for your understanding.
