$ pacman -Q | grep -E "xf86-video-ati|xf86-video-intel"
if not install them.
]]>lsmod |grep radeon
and
mount |grep debugfs
blacklist radeon
//Edit:
In the wiki it is also explained how to achieve your goal, so blacklist radeon as mentioned above and write this to your rc.local:
modprobe radeon
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
happy hacking
]]>none /sys/kernel/debug debugfs defaults 0 0
to:
debugfs /sys/kernel/debug debugfs defaults 0 0
and reedited my rc.local to contain:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
Yet when I reboot and run:
sudo cat /sys/kernel/debug/vgaswitcheroo/switch
I get:
cat: /sys/kernel/debug/vgaswitcheroo/switch: No such file or directory
Does vgsswitcharoo need to be enabled from somewhere else as well??
anyway thanks for the help so far!
]]># mount -t debugfs none /sys/kernel/debug
or to do this automatically edit your /etc/fstab:
debugfs /sys/kernel/debug debugfs defaults 0 0
Afterwards the rc.local method should work.

This is the first time I have installed arch on my HP dv6t. One of the problems with this laptop is that is has hybrid graphics which has always been to wonky for me so I prefer to just disable the ATI card altogether, and solely rely on the intel integrated graphics. Im just not sure about how to get this to work with Arch. I previously had ubuntu installed and used this method to blacklist and disable the ATI card:
To power off ATI Radeon HD card, as root, edit the file /etc/rc.local and append (before "exit 0") :
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
(taken from http://ubuntucomputing.blogspot.com/201 … n-hp.html)
This doesn't work in arch because of what seems to be the lack of vgaswitcharoo and rc.local support.
Anyone Know how to accomplish this in arch.
