Unable to change brightness after kernel upgrade: Sams. R540

Postby nrslmz » 11/11/2012, 14:31

After my last update, I'm unable to change the backlight. I've previously installed samsung-tools 2.16 from the AUR and added
acpi_osi=Linux acpi_backlight=vendor
to /etc/default/grub. I am using the kernel version 3.6.6.1.
There have also been some other problems with glib and glibc. I am also using mate, and the thumbnailer caused 100% memory load. I downgraded them and the problem is solved, but I still can't change the brightness.
Any help is appreciated

Here is the log of my last upgrade

Re: Unable to change brightness after upgrade: Samsung R540

Postby nrslmz » 11/11/2012, 14:54

I've found out that I can change the brightness by echoing to

Code: Select all

/sys/class/backlight/samsung/brightness

So there is no problem with the kernel, but probably mate?
When I use the function keys to change the brightness, it displays the slider, but it doesn't move. Something with permissions maybe?
Anyway, the day is saved for now :)
