Netbook Screen Suddenly Goes Black
Hi all!
I’m running an up to date CentOS-7 on my Acer Aspire One netbook. have been for, well, ever since C7 was released.
Just had an event today that also happened 2 or 3 times with earlier systems installed, but I never pursued it.
What happens is that suddenly while working away on the desktop the display suddenly goes black… not black as in turned off, I can see that the backlight is still on, but no image is displayed.
Nothing I can do fixes it except a reboot. I’ve tried CTRL-ALT-BKSP, CTRL-ALT-DEL, alt+printscreen+r+e+i+s+u+b. none of them do anything noticeable.
I’ve been looking at system logs and don’t find anything that gives me a clue what is going wrong when that happens.
neither dmesg, /var/log/Xorg*, nor /var/log/messages contins much. I’ve tried digging thru “man journalctl” and ultimately reading thru the output of journalctl with no arguments.
Can anyone of you provide further hints on what I should be looking for or at?
thanks!
Fred

I’m typing this on my Acer Aspire One netbook running CentOS 7.
Haven’t encountered that, ever.
Have you checked to insure that your bios is up to date? I have a vague memory of re-flashing the bios on this netbook at some point in the past….
Try with CTRL-ALT-F2 (go to the console) and CTRL-ALT-F1 (go back to the X-Window). This may help…

I’m not suggesting its a CentOS problem, I’m just looking for advice on where to look to get hints as to what is failing.]
hmm. no, I haven’t. I’ll look into that.
oh, sorry, I did try that, but failed to mention it. No, it makes no visible difference at all.
Is it trying to hibernate?
gosh, I hope not! I was in the middle of using it, playing solitaire and moving the mouse around a lot.

Motherboard time. Netbook is probably a throw away issue. Cost more t to repair than buy new.

I might have missed the beginning of this thread: when the screen goes black can you still SSH to the machine (you may need to enable ssh, and switch from DHCP to static IP for this test). If you can ssh, this will mean kernel is still happily running, if not, then kernel might have panicked. I would do what Mark suggests: clean it to avoid overheating
(but don’t do it yet, until you pinpoint the place where it fails). BIOS
turns the machine off completely when temperature threshold is tripped, so tripping temperature sensor threshold is not your case as your screen backlight is still on. However, overheating video chip may do what you see. And it also may open some micro crack. I also would do the following:
attach external screen, make them both ON, and see if only internal panel goes black or both of them do.
Tell us what your experiments reveal.

I recently had the opposite problem. I’d comback to a laptop I knew I had turned off and it was up and running.
Turns out the bios had a setting to automatically power up at 1:30 AM. Perhaps your bios has a “shut down at …”
setting?

thanks for the suggestion!
but I kinda doubt that’s it, this has been highly rare, and doesn’t do it when e.g. I’m at work and leave it on all day.

Hooold on thar! I came into this thread really late (like, today). You’re saying it’s fine at work, but not at home?

No. I’m saying it’s only happened once since I installed C7, not long after it was released. While I haven’t kept records of dates and times, I don’t think it was at any specific time.
I saw it 2 or 3 times previously, probably some Fedora version,… my tired old brain won’t divulge that info right now.
It seems reasonable that it’s some kind of hardware issue but I don’t see anything in the logs I’ve thought to check.
I inquired, hoping some of you could suggest other places to look for info, in retrospect.

Ok, then at that point, I like Valery’s suggestion. Try looking at

OK, it just did it again. The system is still up, I just can’t do anything on the built-in keyboard/screen, but I CAN use SSH to log in. Doing so, I’ve captured a bunch of stuff from journalctl that looks like its probably related, which I’ll paste in here. I will also go look at the Xorg log files to see if they contain anything further of interest.
[later: xorg.0.log doesn’t contain anything that appears related to this failure. the last thing in it is recognition of the USB wireless mouse I had plugged in some minutes prior to the failure (10-30 minutes, as best I can recall). It’s hard to tell what is going on since Xorg.0.log does not display the actual time the reported events occurred.]
BTW, this is CentOS-7, probably up to date, or at least if not, no more than a few days from there, running kernel 3.10.0-327.18.2.el7.x86_64. This system has some generic Intel video chipset, and is an Atom N570, dual core, 64-bit processor, running at a _screaming_ 1.6 GHz. Oh my! :)
I’m looking around in /proc to see if I can find out which generation of Intel video it has. I don’t see it in /proc/cpuinfo, can someone advise me where to look for this info? LATER: this site: http://www.cpu-world.com/CPUs/Atom/Intel-Atom%20N570.html says its graphics engine is GMA-3150. lsmod shows that we have the i915 module loaded
(is that correct for a GMA-3150 graphics chipset?) along with drm_kms_helper and drm. I’ll let it stay in its current (broken) state for a while in case any of you smart guys can suggest other places to look, or things to look for.
thanks in advance!

God made him who had no sin
to be sin for us, so that in him
we might become the righteousness of God.”

I’ve done a lot of searching for this error message, online:
kernel: vblank wait timed out on crtc 1
or
WARNING: at drivers/gpu/drm/drm_irq.c:1141 drm_wait_one_vblank
and find a lot of places where people have had reported the same thing
(most were “crtc 0” instead of “crtc 1”). it seems to have happened to a lot of people, for several years, many on ubuntu, and some of them on a 4.x kernel. I think that most, if not all, of them were reporting using an Intel video chipset, so it is likely an Intel driver bug.
Most of them, however, did not report that they lost video output. In my case, the laptop console becomes useless. I cannot switch to a text console, and nothing I input on the keyboard makes any difference, other than that the screensaver seems to have turned the screen black if I leave it alone long enough, and touching the keyboard turns it gray (i.e., black with backlight on).
what I haven’t found, so far, is any mitigation.
Some reports were that it occurs when switching to or from the X
virtual console, but as far as I can see that isn’t what triggers it in my case. I can’t tell, actually, ’cause I’m just moving along doing random-seeming stuff when suddenly kaboom.
Some reports did show how to turn on drm debugging, boot with:
drm.debug=0x1e
since it happens to me so rarely, I’m not sure I could capture any useful info by doing that.
I’m still open to suggestions, if anyone has any. thanks!
