Hello everyone,
I have a HDMI monitor connected to mini PC with Celeron N4100. The monitor turns off after suspend or when screen is locked as it should be. But when a key is pressed or mouse is moved, the monitor turns on and there is nothing on the screen.
I am able to login through SSH from another PC. I did not know what to look for. The lsusb works but lspci does not return, when the screen is blank. I do not have this problem with other distributions. How do I find the root cause?
Hi, couple days ago a user also reporting same problem with Celeron N4100. May be you could check there.
But I’m not sure the solution works permanent or not. I prevent him to mark it as solved in case the problem come again in the future. Because there, on internet, some users also reporting the same problem (also happen on different distro).
I do not know if I have the same problem. The system is not going in to sleep or hibernate, as I am still able to SSH in to it. And also the monitor connected over HDMI wakes up, but there is no GUI or console.
I do not have any problems with reboot. Force power-off (holding the power button for long) and power-on brings back everything to normal.
As other distros work, I think it’s a bug with particular version of either the Kernel or GNOME.
I suspect the Kernel, as lspci command is not working during the issue.
I have dug a little bit.
I used the lspci -v before the screen lock and there is this device:

Kernel driver in use: snd_hda_intel
Kernel modules: snd_hda_intel, snd_soc_skl, snd_sof_pci_intel_apl
After wake-up, if I do lspci -s 0e, the shell hangs. Every other PCI device prints info, except the above one.
I tried echo 1 > /sys/bus/pci/devices/0000\:00\:0e.0/removeand the shell hung-up
That should be expected since you said the HDMI monitor is blank after suspend or screen lock. Since the HDMI connection failed, it should also impact the sound driver that control the sound trough HDMI connection.
But I’m not sure, maybe you could try to blacklist those three modules snd_hda_intel, snd_soc_skl, snd_sof_pci_intel_apl during the boot and see what happen when you wake up from suspend.
By the way, I’m interesting with your lspci info above. It’s out of topic, but would you like to give info about your soundcard hardware aplay -l and aplay -L? Thank you.
When the snd_hda_intelis blacklisted, the blank screen issue is gone. Of course there are no sound devices available when the driver is blacklisted. Blacklisting the other two drivers didn’t change anything.

Maybe you could create /etc/modprobe.d/alsa-custom.conf and add options snd-intel-dspcfg dsp_driver=1 to the file. Then blacklist only the snd_soc_skl.
If the bug still happen, please report it to https://bugzilla.redhat.com specific to alsa-sof-firmware packages.
If I’m not wrong, the sof firmware technology allowing some modules to assign to same hardware address, that’s why it happen.
Other thing, there a way to run custom systemd service to run before sleep target and after wakeup target. Maybe you could create custom script to remove the module before the system go to sleep and load again after the system back to live. Or maybe it will lot easier to disable the sleep and wait for the bugs fixed.
Btw thank you for sharing the aplay -l and aplay -L. I need this references related to sof firmware if other user here have a problem.
@oprizal , thanks a lot for your help. I have found the solution. According to your advice I wanted to file a bug report and ended up finding the solution.

Solution is to add the following Kernel boot argument:
snd_hda_codec_hdmi.enable_silent_stream=0

My Kernel version is 5.15.11-200.fc35.x86_64. I will try to find out why this version still has the bug.
Awesome!
