Unbound brightness up and down keys

[dadim]

My hp netbook (with amdgpu) has marked f3/f4 keys as related to brightness down & up respectively. I have managed to trim the brightness with either xbacklight commad, or the powerkit slider. However, even when I enable XF86MonBrightnessUp/Down keys via obkey, I can't find the actual keys bound. fn+f11 is volume max and fn+f3/f4 seem to be unbound. The acpi_listen command displays nothing to these key combinations, as well as the xev command.

The xev output to the single pressing of f3/f4 (without the combined fn), is the following:

Code: Select all

KeyRelease event, serial 28, synthetic NO, window 0x2800001,
    root 0x6a7, subw 0x2800002, time 5225626, (42,23), root:(59,309),
    state 0x0, keycode 70 (keysym 0xffc1, F4), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyPress event, serial 28, synthetic NO, window 0x2800001,
    root 0x6a7, subw 0x2800002, time 5229395, (42,23), root:(59,309),
    state 0x0, keycode 69 (keysym 0xffc0, F3), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

I would be grateful for any suggestions.

Thanks, I've already seen that and helped my to install acpilight. My current problem is no more the powerkit brightness slider, or the xbacklight command. It is that the up/down keys seem to relate to no actual key combinations from the keyboard. I don't know if it actually a BIOS problem, I'll try to find it out.

The arrows (up, down, right,left) keys has no action here also in lenovo g510 intel i3.

HP laptops used to bind all function keys to multimedia, brightness, etc by default (and they probably still do so). This caused all shorts of problems. There should a BIOS setting to turn this off and make function keys behave normally, with multimedia functions bound to Fn+F<number> instead of F<number>. But I guess you tried that already; I mention it just in case.

Actually I was not talking about the up/down keys but about the XF86MonBrightnessUp and XF86MonBrightnessDown keys, but I was too lazy to write the full name. Concerning the BIOS settings, they're very primitive and I didn't find anything related there...

Did you remove xbacklight first?
After installing the acpilight package
did you run this ?

Code: Select all

sudo cp /etc/udev/rules.d/90-backlight.rules.new /etc/udev/rules.d/90-backlight.rules

Then reboot.
After login typing xbacklight -50 in the lxterminal is there any respond in brightness ?

Also did you touch the obkey utility?
there the settings are for XF86MonBrightnessDown command xbacklight -10 , enabled: checked, Actions Execute
for XF86MonBrightnessUp command xbacklight +10 , enabled: checked, Actions Execute

Apart from removing the xbacklight package, I had already done these, following your advice in the previous post. Both the xbacklight command and the PowerKit brightness slider are effective. The only problem is that the XF86MonBrightness[Down|Up] keys although they're enabled in obkey seem to be unbounded from the actual keyboard combinations. I've provided some details in my first post above.

Today I removed the xbacklight package as well and rebooted. Nothing changed. My kernel version is 5.15.8 (x86_64). I don't know if it has something to do with the problem.

copy /usr/share/X11/xorg.conf.d/10-amdgpu.conf to /etc/X11/xorg.conf.d/ and then rebooted
I have read that a kernel upgrade may fix the problem.
what is the output of
inxi -G
and
neofetch

what is exactly your HP model laptop ?

I copied it, no changes.
