System get's dark on videos randomly

Support Graphics & Display
1

Hi everyone,

today i am seeking for some ideas how i solve an intermittent problem.

Device is an HP ZBook G5 15" with an Intel Core i7-9850H
The system is equipped with 32 GB RAM and a second decidated NVIDIA Quadro graphics adapter, but this one i never use (i haven’t even installed the driver) because for my tasks the internal Intel (Intel CoffeeLake-H GT2 [UHD Graphics 630] ) is sufficient.

Every now and then while watching a video, the system crashes. The screen turns dark, keyboard is not reacting at all.
I have to long press the power button, then the little LED in the Shift-Lock is flashing for a second.
Once this is done, i can restart the device and it works as if nothing happened.

The problem can occur totally random once or twice a day, sometimes the device runs for days.
It is also not impacted
There is nothing in the logs as far as i can see.
Installed is Manjaro latest stable and properly updated with KDE on Wayland.
But it also crashes after a fresh install and/or on X. It also does not depend if it’s browser based (e.g. Youtube) or a locally installed Video via VLC Player

Any ideas where i can start troubleshooting are much appreciated.
Thanks

Are you running out of RAM after some hours? Uptime only 1h41 and 12.3% in use, presumably being used mainly by the browser.

I assume of course you are watching the videos using a web browser? :wink:

Worth keeping an eye on it with a Terminal window running e.g.:

watch -n30 free -h

Hi,

never had RAM problems. It’s completely independent how long the system is running.
There are 32 GB RAM installed, most of the time it runs with less than 20% of it.
Currently two browser instances open with seven tabs in total.

              gesamt       benutzt     frei      gemns.  Puffer/Cache verfügbar
Speicher:       30Gi       4,5Gi        23Gi       781Mi       4,0Gi        26Gi
Swap:             0B          0B          0B

I watch most videos via browser. But even locally copied files from a different source are having the issue intermittently playing it via VLC.
As i am not doing that often, it happens less than in a browser session.
Oh, and it doesn’t matter which browser i am using. Chromium, Firefox, Brave, Opera…

EDIT: I sometimes edit 4K videos or larger pictures where RAM is required. Never had a single issue there so far.

Thanks
Uwe

How about the log

journalctl --no-pager -b-1

That gives the full log of the last boot.

Maybe use -e to get to the end directly.

Yes, but the problem occurs before that boot which is required after the system got stuck. I don’t think there is much helpful in it.

EDIT: scrolled back and found this, followed by the dump itself:

But i am not sure if this was caused by the issue i am talking about, because the time in between was too short for a full reboot with power down.

You could try different VLC outputs to see if that makes a difference.

Tools > Preferences → Output

Some are better than others, depending on your system, but be warned – some of these may actually cause a crash while you’re experimenting.

I use SMPlayer, which always seems lighter than VLC – The default theme looks rather ugly, but can be changed if desired.

sudo pacman -S smplayer smplayer-skins smplayer-themes

There is also KDE’s Dragon Player which is lighter still.

sudo pacman -S dragon

Dragon is a very simple player, without many settings to bother with.

If neither of these players demonstrate any improvement, it could be that the UHD Graphics 630 isn’t quite as sufficient for your needs.

I’ve tried different players. As i do not play local videos often, i think there is no evidence which works best.
However the majority of my videos are either Youtube or a different online source via browser where none of the locally installed players would help.

The graphics adapter shouldn’t be the problem playing random HD videos.
As said, it is working fine sometimes for days, even if the device was running for many hours. And the next days it occurs 2-3 times within hours.

EDIT:
Forgotten to mention something, maybe it’s important:
When the crash occurs, it happens everytime when a video tries to start. It never happened so far while the video is already running.

One more idea:

As i am not able to find anything useful in the logs, could it be that the system didn’t crash but simply darken the screen and disable the keyboard but keeps running in the background?

Sounds stupid, but i have no idea otherwise…

11

UNIX systems are quite convoluted in that regard. There is a pecking order when it comes to keyboard input, but most people don’t realize that.

A keyboard is a hardware device. Therefore, keyboard input is handled first and foremost by the kernel, albeit that the kernel can’t really do anything with it unless they are effectively kernel commands, i.e. the one-key System Requests — the “REISUB” thing, even though there are more System Requests than just those seven. For the kernel to interpret these one-character commands, the keyboard needs to be put in unraw mode first by way of the AltSysRqR System Request.

As such, with the above in mind, the kernel forwards the keyboard output to the console — in practice, this means the tty (terminal), even though they are actually not the same thing. The terminal understands a number of keyboard inputs of its own, but those are usually inputs by way of a control character — commonly by pressing Ctrl or Alt (or both) in combination with another key.

If the keyboard input is neither a System Request nor a terminal command, then the terminal will forward the input to the active process in the terminal. If you’re in a GUI environment, then that active process will be X11 or your Wayland compositor.

If the input still does not match the X11 server or Wayland compositor, then it gets forwarded to the active application on the desktop.

The bottom line is that if the system does not appear to respond to keyboard input, then there are several layers where the input fails to reach the system. A locked up application can effectively freeze your keyboard while your desktop environment is still running, or while the kernel is still running.

The System Requests are therefore the only way to test whether your system is still alive, because even though the keyboard may appear to be frozen, each of the System Requests will at least provide some feedback if you give it a few seconds, even if it’s only through the drive activity light.

Let’s assume for a moment the plasmashell process actually crashed (as mentioned in your log). Then a black screen will be the logical result.

In this case you can still switch/login to another tty (for example Ctrl+Alt+F4). From there you should be able to restart the plasma session.

systemctl restart --user plasma-plasmashell.service

Please note this is just a workaround for the actual bug - not a solution.

That is not the preferred method. KDE recommends… :backhand_index_pointing_down:

kquitapp6 plasmashell && kstart plasmashell

Thanks for the suggestions, will give it a try once it crashes again

As far as i see, the keyboard is not responsive, in the past i was only able to push the power button (long) to get a full system reset and then restart again (wrote it in the initial post).
Even the Shift-Lock/Num-Lock buttons (with LEDs in it) aren’t responding.

However, i will try all of the given options.

This means that the kernel is dead. In that case, a hard reset is indeed the only option. :man_shrugging:

Thanks for your reply.

Have you tried updating the kernel?

Is this going to my problem? I am using this one on stable release. Seem to be the latest one there:

6.12.73-1-MANJARO #1 SMP PREEMPT_DYNAMIC Mon, 16 Feb 2026 21:36:06 +0000

Which one should i use?
EDIT: Currently updating to 6.18.12-1 because it is shown to me as “LTS” Kernel

Yes, 6.18 is the latest LTS kernel, and will be supported until at least December 2027. :wink:
