|
Hello Forum,
I recently switched from Ubuntu to Gentoo and first of all I have to say that I quite like it: It gives me the freedom ubunto promises xD
Okay here now my problem:
I wanted to enable backlight control for my MSI laptop. I found this:
http://www.thinkwiki.org/wiki/How_to_make_ACPI_work#Backlight_problems_with_post-2.6.26_kernels
And when I set
| Code: | Power Management Options --->
[*] ACPI (Advanced Configuration and Power Interface) Support --->
<*> Video
|
maked and copied the kernel to /boot/ and rebooted, I indeed was able to dim the backlight, but my touchpad didn't work anymore.
I tried around a bit and found out that when I disable ony the feature "Video", my touchpad works again, but my backlight don't.
I don't see any link between my touchpad and the acpi video support.
Can anyone help me, please?
Btw: I'm using 2.6.37-gentoo-r4 with menuconfig and I have a
01:00.0 VGA compatible controller: nVidia Corporation G84 [GeForce 8600M GT] (rev a1)
I'm thanking you in anticipation 
Wauzl

This guy has also a MSI Laptop and his touchpad didn't work properly, after deactivating the ACPI video support it worked for him.
EDIT:
It helped me to build the kernel with only modular support for acpi video:
| Code: | Power Management Options --->
[*] ACPI (Advanced Configuration and Power Interface) Support --->
<M> Video
|
When I rebooted with a compiled kernel with this configuration, the video.ko was loaded automatically and I was able to use my touchpad and control my panel brightness.
I hope this helps anyone |
