Display doesn't wake up from sleep

English Applications
1

Notice this after booting up this morning (my time). I can’t wake the monitor after leaving it for some time when it goes to sleep by itself. I also have a keyboard shortcut that triggers

sleep 0.5; xset dpms force off

After hitting it I can’t wake up the monitor either. It’s connected via hdmi and I have only KDE desktop installed here.

The only thing that works is hard reset with a power button.

On the internet someone once suggested running

xrandr --auto

to check whether it’s a bug or not. This doesn’t work for me. When screen goes off I can run this command by opening terminal with a Ctrl-Alt-T shortcut and then typing it blindly or going back in bash history with arrow up. Nothing happens and I, of course, can’t see the messages. I can ssh into the machine and it still works, but xrandr fails with “Cannot connect to display” message.

On trying to wake up the monitor with keyboard some light comes on - it changes color from black to dark grey.

I’ve updated the system with a bunch of new packages getting installed but the issue persists.

For now I’ve disabled Screen Energy Saving Switch off in KDE Power Management settings but this is not ideal.

2

I’ve created a custom shortcut to capture xrandr output into a file and run the same command in terminal when monitor is not waking up - it appears that no keyboard input registers at all. Custom shortcut doesn’t trigger the action and terminal doesn’t open with Ctrl-Alt-T, so cycling through bash history does not work either.

Keyboard itself still has it lights on and hitting it still brings up some kind of backlight to the display so it looks like its trying to wake up but can’t.

I reinstalled Tumbleweed last night and I have the same situation on my computer.

Probably you were hit by this problem:

By all accounts - yes. Takashi Iwai’s suggested workaround works - I added

snd_hda_codec_hdmi.enable_silent_stream=0

to boot options, first manually, then permanently with Yast Boot loader, and the system wakes up again. I can’t decipher what the problem is exactly and when it can be properly fixed. Something to do with old Intel hdmi sound drivers, which I never got to work on this machine anyway.

Thanks Susejunky, this has been very helpful.

PS. I tried blacklisting it as suggested in a link in bugzilla:

# /etc/modprobe.d/snd_hda.conf
options snd_hda_codec_hdmi enable_silent_stream=N

but was unsuccessful. For single monitor N should be 0, I guess, and I created /etc/modprobe.d/snd_hda.conf file with the line “options …” but it didn’t work. Maybe I wasn’t doing it right.

6

What should I do?
Do I add a file /etc/modprobe.d/snd_hda.conf and edit there a line *options snd_hda_codec_hdmi enable_silent_stream=0 *?

7

Hi
Add it to the grub kernel boot options, YaST -> bootloader

8

URL: SUSE Paste

Sorry, I have a Finnish version of Tumbleweed …

You mean Yast2 and bootloader?
And there ‘core parameters’?
And ‘Kernel Optional Command Line Parameters’?
That line now has ‘splash = silent quiet’.
Do I put a comma-separated line on that line (options snd_hda_codec_hdmi enable_silent_stream = 0)?SUSE Paste

URL: SUSE Paste

Hi
Yes after the ‘splash = silent quiet’. So this worked for you?

10

I have done some testing.

  1. The setting on Yast did not work. Act as before.

URL: SUSE Paste

  1. I edited a line options snd_hda_codec_hdmi enable_silent_stream=0 to */etc/modprobe.d/snd_hda.conf *file.
    This work for me.
**localhost:~ #** nano /etc/modprobe.d/snd_hda.conf
**localhost:~ #**
**localhost:~ #** cat /etc/modprobe.d/snd_hda.conf
options snd_hda_codec_hdmi enable_silent_stream=0
**localhost:~ #**

URL: SUSE Paste

ps. I am also studying adding an image to a site.:wink:

I have done some testing.

No comma, only a blank space to the command before.

12

Still works same way. On the other words don’t work for me.

URL: SUSE Paste

ps. I prefer images because text don’t need to be translated :slight_smile:

13

Only add snd_hda_codec_hdmi.enable_silent_stream=0 DO NOT add options and there must be no spaces before or after the =.

The input field in YaST should look like this

splash=silent quiet snd_hda_codec_hdmi.enable_silent_stream=0

susejunky

14

Thank you!
I finally understand what to do.

It’s embarrassing to ask the same thing many times when you don’t understand the text. :shame:

15

Finally, the Yast2 trick works as it should.

16

Thank you for your information.
I’m experiencing the same issue, but the solution does not work for me.

I have tried the


cat /etc/modprobe.d/snd_hda.confoptions snd_hda_codec_hdmi enable_silent_stream=0

and the kernel option to boot with


hda_codec_hdmi.enable_silent_stream=0

Both options do not work.

After I wake up my system. The first monitor start, but the second one stays black.

If I run

 xrandr --auto --output DP-3 --mode 1920x1080 --right-of DP-1-1

then the second monitor will wake up and the desktop will extend to the second monitor.

I have to run this command every time my monitors wake up.

I tried both Wayland and Xorg servers when logging in.

Do you have any other options to try?

This is a laptop with a USB-C docking station with 2 HDMI monitors connected to it.

Could be a different problem.
What is your DE

The following command usually gets the second monitor to wake up:

xrandr --auto --output DP-3 --mode 1920x1080 --right-of DP-1-1

The following command avoids the issue, but obviously disables EnergyStar:

xset -dpms
