Red Hat Bugzilla – Bug 847090
After resume: screen cannot be woken up i915
Last modified: 2013-01-25 08:44:59 EST
Description of problem:
If I leave my computer and come back to it several hours later, the monitor is unresponsive. I can log into the computer using ssh.
I had a similar problem on an Ubuntu system, also with an i915 graphics card. The workaround was to boot with i915.i915_enable_rc6=0.
I did not have this problem until quite recently, maybe a week or two ago.
Version-Release number of selected component (if applicable):
# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
Would like to request increased severity, since this is a data loss bug: I lose all of the state in the applications I am working on.
This happens after a resume from suspend. Switching consoles does not help. In fact nothing but a reboot helps.
