Unable to change brightness via hotkeys

[yxinolija]

Hi, as title says im unable to change brightness either on installed gecko plasma or live one. Pressing Fn+F12 or F11 doesnt do anything, i have to manually adjust from Energy Saving screen. Machine is a Lenovo Ideapad, OpenSUSE works fine.

Thanks for any suggestions.

Hi, which ISO did you try?

[yxinolija]

GeckoLinux_ROLLING_Plasma.x86_64-999.210102.0

[yxinolija]

And Linux Mint, OpenSUSE Tumbleweed, GeckoLinux Static just now.

@yxinolija Thanks, do those other editions with Plasma have the same issue?

[yxinolija]

Only in Gecko Rolling for some reason, the rest of distros are functional, Plasma or not.

@yxinolija Thanks for reporting this, I can confirm this behavior on my test laptop as well. There must be a "recommended" package that is not being installed that is needed for this functionality. I'll have to track it down. Any suggestions or tips about which package it is would be welcome.

[yxinolija]

I see. I'll see what I can find.

[geckolinux]

Thanks for the help. As a suggestion, maybe try comparing the list of installed packages in the current Tumbleweed live ISO with the GeckoLinux ISO.

when i WinMerged the lists of installed packages i found some not installed. i tried installing missing packages: _intel-media-driver, intel-vaapi-driver, librdrmintel1, ucode-intel, kernel-firmware-intel, acpica, cpupower, libvdpau-nouveau, Mesa-dri-nouveau with no changes.

Also tried creating 20-intel.conf from here, but it renders SDDM inactive(dead) with unable to display on vt7 or something. Deleting that file makes SDDM active again.

Kernel parameters _acpi_osi= , acpiosi=Linux didnt help either.

EDIT:

i tried changing global shortcuts to something else, doesnt do a thing. Only some shortcuts displayed moving brightness bar that its going from 100% and down but brightness was still the same value.

[geckolinux]

Thanks for the attempts. It's definitely a missing or included package that is causing the problem, because the Plasma Energy manager has the brightness slider and it works correctly, so it's not a kernel or ACPI issue.

[geckolinux]

OK, I found the problem, it wasn't a missing package, but rather the config file ~/.config/kglobalshortcutsrc . Try deleting that and it should fix it. I'll generate a new ISO with this fix ASAP, but unfortunately there's currently a blocking issue upstream: http://bugzilla.opensuse.org/show_bug.cgi?id=1181620

Thanks to @yxinolija for reporting this important issue.

[yxinolija]

Yeah, i forgot about that. No problem, glad i could help somehow.
