What happens if you don't have X running? Does it always work? It seems you're using Debian, so you can try to use the "text" Kernel parameter to test this. Thanks, Paulo Please close, I returned the laptop. Sent from my mobile, please pardon the brevity.

Did you conclude somehow that the problem was happening because the hardware had a problem? I was expecting this bug to be our fault since we don't have many users of 3200x1800 yet :( It was not the hardware, I returned it, twice. Sent from my mobile, please pardon the brevity.

Thanks for the report. If you get the machine again, please reopen the bug. 3200x1800 sounds too exciting to not work :) Hi I'm re-opening this since the issue I'm seeing sounds very similiar, I'm also on haswell HD4400 (Dell Latitude 7440) and I'm seeing the issue running everything from 3.12 through to 3.14rc7, though my LVDS is just 1080p not exciting 3200x1800. I'm basically having the screen go black at random times or as random as I can tell since there seems to be no correlation with what I am doing, if the laptop is in the eDock, connected by HDMI or with no external display. I'll attach the dmesg snippet of what I got the last time this happened a few min ago, though when it did, I'm sorry I instinctly did ctrl-alt-f1 to switch virt console then alt-f7 to go back to X as I have noticed that once in a while, doing this brings the lvds screen back on (but this time it didnt).

dmesg snippet with "drm.debug=0xe" set
Sorry I should have also said that I am usually running with the patch from https://bugs.freedesktop.org/show_bug.cgi?id=73694 applied, though I have seen this happen when running with kernels without the patch applied. Also sometimes this occurs, even a reboot does not resolve the problem - even the firmware ("bios") splash screens dont show and I have to pull out the battery and reboot - this has only happened when I've been out and not has an external screen to connect to, as when this same thing happens when docked in a Dell eDock or connected to HDMI via laptops own HDMI port, I see the firmware boot screens show up on the external monitor. Also since I'm building my own kernel already I'm happy to try out any patches or alternative git branches that people could point me to test. sorry forgot to include from lspci -v in case it helps:

full dmesg shwoing issue happening soon after boot
Hi, sorry, being a dev myself, I realised how annoying it would be to just have the log snippet, so I managed to get a full dmesg, with the laptop scree going black a little after a boot, with a ext monitor connected via laptops own hdmi port (not edock).
I didnt notice exactly when it happended, but I think it was around the 09:19:53 mark in the dmesg log attached.
Hope this helps.
First things first, please check your kernel build process and make sure your kernel and modules aren't tainted. Grep for "taint" in the dmesg. This one you'll need to figure out yourself. One thing to try is i915.i915_enable_fbc=0 (or i915.enable_fbc=0 on drm-next). Thanks Jani. I did and I do get: dmesg|grep taint [Tue Apr 1 08:13:41 2014] videodev: module has bad taint, not creating trace events [Tue Apr 1 08:13:42 2014] kvm: module has bad taint, not creating trace events I thought "taints" were something to with using binary only (non gpl'd) kernel modules but I guess this is something else since I'm running a mainline kernel I built myself - as you say I'll google and try to educate myself on this. And thanks for the suggested kernel params, I'll try them too. Also would I be better off trying to compile from the drm-next branch instead of Linus's master branch? (In reply to comment #13) > Also would I be better off trying to compile from the drm-next branch > instead of Linus's master branch? The released v3.14 is fine for now. We're in the middle of the merge window so Linus' master might be a bit too volatile right now. Hi, Ok having read this LWN article http://lwn.net/Articles/588799/ I'm assumming this output: dmesg|grep taint [Thu Apr 3 11:41:39 2014] sdhci: module verification failed: signature and/or required key missing - tainting kernel [Thu Apr 3 11:41:40 2014] sunrpc: module has bad taint, not creating trace events [Thu Apr 3 11:41:40 2014] nfs: module has bad taint, not creating trace events [Thu Apr 3 11:41:40 2014] cfg80211: module has bad taint, not creating trace events ...etc is just because of the bad re-use of the taint flag that will be fixed in 3.15 So given I'm building my own 3.14 kernel with just 1 patch applied from Daniel (bug #73694), I'm pretty sure I dont have any tainted modules. I'm rebuilding the 3.14 released kernel now (instead of rc7), will try using "i915.i915_enable_fbc=0" and will report back. Ok maybe I got the wrong end of the stick there - I just tried: cat /proc/sys/kernel/tainted 2 and according to this (http://kmaiti.blogspot.com.au/2011/09/how-to-check-whether-current-running.html) it means I have done a forced module load, but I have just booted (ubuntu 12.02.3) and done no such thing myself - does ubuntu to this for some reason in a init script for some reason? More to the point: I have found my trial&error that doing a switch from virt console 7 to 1 then back into X again and then suspending the laptop and waking it again immediately does seem to bring the screen back on again. Doing jsut one of those 2 actions does not. Though it seems that after 3 or 4 times of doing that, that stops working too and then nothing short of force powering down, pulling battery and restarting fixes it. Save your breath it seems things like this never get solved, I returned the laptop and bought a different one... I had the same behavior with tty terminals too... Sent from my mobile, please pardon the brevity.

Even though this is a *VERY* annoying issue when I'm using the laptop without an external monitor, I'm hoping that if I can provide the kernels devs where with enough information, they can figure out what the issue is or at least a workaround. sorry to waste everyones time - this has turned out to be a hardware fault with the laptop. In the future please file a new bug report, even when you're fairly sure that the symptoms match. GFX bugs are tricky and bugzilla is a pain when unrelated issues are mixed together in one report. |
