My brightness keys don’t work which is expected since there’s no way on the gnome to configure the brightness as well. What do you suppose I do? I’m not sure what kinda information you guys need but on other distros I fixed the brightness by modifying grub.
I saw great replies elsewhere in a kernel parameters kind of post. Maybe try detailing what you did to get grub to make it work? Then one of the devs familiar with systemd boot may be able to help.
I was stunned that everything worked on my very new architecture laptop - even touch screen. I previously ONLY bought year-old model laptops to minimize linux flakiness.
I set the line below like so.
GRUB_CMDLINE_LINUX = “acpi_osi=”
This enabled me to change brightness on other distros.
I’m still a linux noob, so I don’t know how one would go about doing this on clear linux to get adjustable brightness.
I’m not a linux noob and don’t know how one would go about doing this on clear linux. Been a *buntu fanboy for over a decade… always thought it could be better. Oh dang, just remembered I installed redhat on a PC in 1995 or so when in college. I’ll never forget the first time I saw terminus . That makes me a crusty old one…
So how would one achieve brightness control in systemd-boot?
This thread explains adding kernel parameters to boot How do you pass a boot parameter to the kernel on boot?
acpi_osi= is just a kernel boot parameter
Thanks! That worked a charm.
I assume I can now remove the kernel directory now that it’s applied?
No. Every time the kernel is updated it will take the default parameters that are shipped by Clear in the kernel bundle and then add to that what users have added in
/etc/kernel as you’ve done. If you remove the files you’ve created the option will no longer be added next time
clr-boot-manager is run. Hint this will be next time a kernel is updated, so likely 1-2 times per week, so will be gone pretty quickly. In the same way, if you ever need to change them, they will get updated pretty quickly, but running
clr-boot-manager manually ensures it is updated for next boot on all kernels.
