Installing a newer kernel for AR9485 driver breaks display

[ahmed]

Hello:

I'm trying to install Atheros AR9485 wireless card driver on debian, and I had no luck.

I followed this http://forums.debian.net/viewtopic.php?f=7&t=95848 to install backports kernel version. The wireless card worked, however, intel display driver displayed the color in the wrong way.

Red pixels are green, and green are yellow. It was displayed like when someone try to connect a PAL system to a TV that supports only NTSC.

This is my lspci output:

Code: Select all

Is there is a way to compile only AR9485 module from the kernel?

Edit: Solved! Add the following

Code: Select all

i915.i915_enable_fbc=0

to your GRUB_CMDLINE_LINUX_DEFAULT= in /etc/default/grub so you would have something like that

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT=" i915.i915_enable_fbc=0 nomodeset quiet splash"
