Adjusting screen brightness to lowest level turns screen off and doesn't turn on again

sour · 17 June 2021 10:53

I am using a Dell XPS 9310 (intel i915 driver) with KDE Plasma and when adjusting the brightness to lowest level, the screen turns off (I guess?) and doesn’t come back on when brightness values are increased. I have to shut the laptop and then open it again causing it to go into sleep and then resume, at which the screen will turn back on.

I am running linux513 5.13.rc5.d0606.g614124b-1, but had the issue on linux512 5.12.9-1 as well.

I think it might have been fixed in rc4, but the system was crashing very frequently and I went back to 5.12 until rc5 came through.

I’m on linux-firmware 20210518.r1928.f846292-1.

Can anyone guide me in the right direction please?

Here is the journalctl logs of the event where the power settings tries to dim/shut off (?) the screen causing it to blackout and not return.

Have you tried one of the LTS kernels already? (5.10 would be high on my list)

What’s the output of:

ls /sys/class/backlight
inxi --admin --verbosity=7 --filter --no-host --width

sour · 18 June 2021 12:14

I haven’t tried a LTS kernel due to how new the hardware is. I was worried more things would stop working, but I will give it a try.

Ensure all files are saved and nothing important is running!
Execute the following:
```
sudo e /usr/local/bin/test-brightness
```

copy-paste this in there:

#!/bin/bash

echo "Current brightness:"
cat /sys/class/backlight/intel_backlight/actual_brightness
cat /sys/class/backlight/intel_backlight/brightness
orig_brightness=$(cat /sys/class/backlight/intel_backlight/brightness)
sleep 2
echo "Setting brightness to 10"
echo 10 | sudo tee /sys/class/backlight/intel_backlight/brightness
cat /sys/class/backlight/intel_backlight/actual_brightness
cat /sys/class/backlight/intel_backlight/brightness
sleep 2
echo "Setting brightness to 1"
echo 1 | sudo tee /sys/class/backlight/intel_backlight/brightness
cat /sys/class/backlight/intel_backlight/actual_brightness
cat /sys/class/backlight/intel_backlight/brightness
sleep 2

echo "Forcing monitor on"
xset dpms force on
echo "Rebooting PC.  Hit [Ctrl][C] to prevent your computer from rebooting"
sleep 10
sudo reboot

Ctrl+X Y Enter to save
Execute the following to make this file executable:
```
chmod a+x /usr/local/bin/test-brightness
```
Now execute the file by typing:
```
sudo test-brightness
```

If:

Your computer reboots without the monitor waking up, just tell me
Your monitor comes up and you see:

- hit Ctrl+C repleatedly untill you see your prompt again.

I had to fix the script a bit, but the screen brightness drops from 282 to 10 to 1, at which the screen is still on but very low. Then the brightness drops to 0 and the screen is off. I waited a bit, 10 seconds or so, screen doesn’t come back on so I closed the lid and opened it again to bring the screen back on (I disabled the reboot part of the script).

↳ sudo bash test-brightness.sh

Looks like a bug:

should have read:

So file a bug with the Linux kernel development team if none of the LTS kernels work.
