Bug Description
When resuming my laptop from sleep via the keyboard, occasionally X will freeze up - this is usually associated with one of my monitors not displaying output. I can't reach a terminal with Ctrl-Alt-F2 and I have to open the laptop and reboot with Alt-PrtScr-(REISUB) (hard reboot) - the USB keyboard won't work in this situation.
This only happens occasionally and will usually happen if I wake the laptop before turning the screens back on.
There are other cases that can also trigger X freezes but I'm not sure if they are related (eg. unplugging screens).
The following is commonly seen in dmesg during normal behaviour:

Will Shackleton, as per http:// www.dell. com/support/ home/us/ en/04/product- support/ product/ precision- m3800-workstati on/drivers an update to your computer's buggy and outdated BIOS is available (A07). If you update to this following https:/ /help.ubuntu. com/community/ BIOSUpdate does it change anything?
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:/ /help.ubuntu. com/community/ ReportingBugs# Bug_reporting_ etiquette .
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.
