hooray, i found my credit card again and did a donation to Arch Linux :D paypal would have been much easier for me, i don't usually use credit cards but now i can tick this off my todo list :D in case anyone is using the full hd screen on the aspire E5-571G that normally uses a lower resolution screen, my Period setting is 061A, it only flickers once every 4 minutes :D couldn't find any more precise setting

@kingcreole. Thanks for your kind words. No, there is no way to buy me a coffee unless you live in Washington DC or around :)

If you wish to express your gratitude, consider instead donating to Arch Linux please.

hey edio, i'm so gratefull that you made this, my screen was flickering so badly, now it just flickers once every 4 minutes or so :D is there a tip-jar or an organisation i can express my gratitude to monetarily? i'd love to gift you a bag of coffee for having fixed my replacement laptop screen :D

Thanks for fixing it!

@Franek, fixed shebang. Thanks for noticing

Franek commented on 2018-08-27 13:50 (UTC)

Please change the shebang of the script to require bash instead of sh. After symlinking /usr/bin/sh to dash on my system, intelpwm fails with:

/usr/bin/intelpwm: 8: /usr/bin/intelpwm: source: not found
Warning: register spec not found in '/usr/share/intel-gpu-tools/registers'. Using builtin register spec.
read: no registers specified
/usr/bin/intelpwm: 11: /usr/bin/intelpwm: Bad substitution

(The warning is normal, the rest is not.)

Changing the shebang to

#!/usr/bin/env bash

fixes it.

This fixes the rule for me. Now it could be used alongside rules that depends on ACTION=="change"

 KERNEL!="intel_backlight", SUBSYSTEM!="backlight", ACTION!="change", GOTO="backlight_pwm_rules_end"

@sheinz, thanks a lot! This way makes backlight controls in various DEs (like GNOME) actually aware of the new PWM frequency!

I solved the problem not using udev at all. I used modprobe.d config file. /etc/modprobe.d/i915-pwm.conf: install i915 /usr/bin/intelpwm; /sbin/modprobe i915 --ignore-install This will call intelpwm before i915 module is loaded.

99-intelpwm.rules blocks 85-tlp.rules from execution. After installing this aur tlp stopped auto mode switching. As far as I can see this 99-intelpwm.rules brakes any rule that uses ACTION="change"
