(i915) Black screen resuming from suspend

[Nikke]

Similar to Bug #1336227 and Bug #966744, intermittedly when resuming from suspend I get a black screen with only a visible mouse pointer. Sometimes I can move the mouse pointer. I have the feeling it occurs more often when disconnecting an external monitor while in suspend.

I can always switch to a VT, and sometimes I'm able to get everything going again by killing compiz and restarting unity:
>>> killall -9 compiz
>>> unity --replace &

But most oft, only way is to restart the lightdm service...

All the best,
Niklas

Nikke, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

As this is the computer I use for work, I don't dare to fiddle around with new kernels...

But, I can add that it seems that 'unity-panel-service --lockscreen-mode' may workaround the issue.

All the best,
/Niklas

EDIT:
"But, I can add that it seems that 'unity-panel-service --lockscreen-mode' may workaround the issue."
should be
"But, I can add that it seems that /KILLING/ 'unity-panel-service --lockscreen-mode' may workaround the issue."
