XORG crashed after waking up from sleep

[Logan D. Johns]

Laptop: HP DM1Z
Xubuntu 14.04

I close the lid to enter a sleep state. When I come back, I open the lid an the unlock screen appears. I enter my password, press enter, then screen goes blank. The display shows nothing and the back light appears to switch off. Next, the laptop reboots.

Status changed to 'Confirmed' because the bug affects multiple users.

I am experiencing this in Xubuntu 14.04 too. I have substituted lighdm with xdm. What information I can provide to help fixing this?

[Bryan Morrison (skeeter-mcbee-y)]

I'm Experiencing something similar to this in 14.10. Instead of sometimes, every time I wake my laptop from sleep, my entire x server crashes and cannot be restarted. I cannot log in, and the GUI is unrecoverable without a restart.
