[Bug 1418295] Re: Black screen after resuming from suspend
I don't know, if this one helps, or is even a correct additional info: I
believe, that this freeze here (blank screen with just mouse pointer)
happens, when I touch the touchscreen during the initial parts of the
resume process. I've learned to keep my fingers off the screen directly
after resume, and it seems, that since then, this problem has been less
often.

Title:
Black screen after resuming from suspend
Status in xserver-xorg-video-intel package in Ubuntu:
Incomplete
Bug description:
Using Ubuntu 14.10 on a Lenovo Yoga 2, when I resume the laptop from
suspend I frequently (around 50% of the time) get a blank black screen
with a mouse cursor on it, and am unable to login or interact with the
desktop at all. Often (also about 50% of the time) switching over to a
text terminal and killing "unity-panel-service --lockscreen-mode"
causes it to snap out of it and prompt me with the unlock dialog when
I switch back to X.
