 |
|
Hello,
I never was able to change brightness level of my laptop screen, a HP EliteBook 8560w.
It's using the last 6.6.16 kernel.
After trying the differents things reported in the wiki, it just doesn't works, no matter which brightness file is edited.
On #gentoo, someone told me I might need the HP WMI support in the kernel, compile it and try.
Despite having now:
| Code: |
laptopGentoo ~ # uname -a
Linux laptopGentoo 6.6.16-gentoo-dist #1 SMP PREEMPT_DYNAMIC Fri Mar 15 00:32:59 CET 2024 x86_64 Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz GenuineIntel GNU/Linux |
| Code: | | laptopGentoo ~ # modprobe hp-wmi |
| Code: | laptopGentoo ~ # lsmod | grep hp
hp_wmi 20480 0
sparse_keymap 12288 1 hp_wmi
platform_profile 12288 1 hp_wmi
rfkill 32768 6 hp_wmi,bluetooth,cfg80211
hp_accel 28672 0
lis3lv02d 28672 1 hp_accel
wmi 36864 5 hp_wmi,video,wmi_bmof,mxm_wmi,nouveau
|
So, if hp_wmi was needed, what it is missing now ?
Shortcut as the Plasma GUI doesn't change it too, by the way.
Any ideas ?
Regards,
GASPARD DE RENEFORT Kévin

And maybe that is relevant, but at this point I'm lost:
