xorg _log

There are odd black/blank/gray screen issues that are occurring with the intel-drm driver in the 3.11.1 kernel.

Sometimes, on a cold-boot the login manager (gdm3 in this case) will properly show but after entering credentials the screen will either produce a black screen or gray screen with thick black lines.

This will happen 50% of the time. About 10% of the time switching to a virtual terminal and back will fix the issue and display the desktop as expected.

This also happens randomly after a suspend/resume cycle.

Xorg log attached and it appears clean, the log does not differ when the bug happens.

I am not passing any relevant kernel parameters at boot but when using the nomodeset option, there are no issues present.

3.12 RC2 kernel was compiled and the issue is still present.

I really wasn't too sure what else is needed for this bug report, please let me know if additional information is needed and I will provide it promptly.

I'm attaching a new xorg, the issue just happened after a logout and an attempted login. I switched to VT1 and back and was able to resume without a reboot.

Update xf86-video-intel for a workaround.
Comment 4 drewvs 2013-09-29 16:06:04 UTC 
Chris, I pulled the driver last night and compiled. Issue is still present.
Comment 5 Chris Wilson 2013-09-29 16:20:51 UTC 
The last logfile is still an old driver from before the Haswell w/a I was thinking of. However, I mistook your 3200 pixel wide eDP for an extended desktop and so the issue is not the same one anyway.
Comment 6 drewvs 2013-09-29 16:24:28 UTC 
Chris, I had downloaded the source tar from the Intel graphics Q3 bundle with a -903 release. I'll pull from git anyway so I'm running any fixes not included in it. 

You are correct, the laptop screen is a 3200x1800 pixel screen--which surprisingly works at that or lesser resolutions.

I've updated the xf86-video-intel driver. Same issue, just resumed and had a blank screen--forced to reboot. Here is the updated Xorg log.

Is there anything else I can provide?
Comment 8 Jani Nikula 2013-10-09 13:31:43 UTC 
Please add drm.debug=0xe module parameter, and provide dmesg from boot to the issue. If it usually takes a long time, you may need to increase log_buf_size. Let's see if there's anything of interest there.
Comment 9 Rodrigo Vivi 2014-01-30 09:24:58 UTC 
Do you still see this issue with latest drm-intel-nightly from http://cgit.freedesktop.org/~danvet/drm-intel/log/?h=drm-intel-nightly
and latest xf86-video-intel from http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/

Could you please provide new xorg log and also the info requested by Jani: dmesg with kernel booted with drm.debug=0xe.
Comment 10 Rodrigo Vivi 2014-03-14 14:27:47 UTC 
Hi there,

It's been a while with no input. Feel free to reopen it with proper logs at any time if you are still facing the issue.

Thanks,
Rodrigo.
