[Fra B <frab1215@xxxxxxxxx>]

Hi to everyone,
I've got an Asus 1215N.
I use Mandriva 2010.2 x86_64.

Recently I've compiled kernel 2.6.38 from kernel.org.

In my linux distribution i915 and nouveau kernel module are blacklisted, and
I've uncomment this 2 line in /etc/modprobe.d/blacklist-mdv.
So I can load both this 2 modules:

# lsmod | grep i915
i915                  487045  2
drm_kms_helper         34769  2 nouveau,i915
drm                   215732  5 nouveau,ttm,i915,drm_kms_helper
i2c_algo_bit            5705  2 nouveau,i915
button                  6065  2 nouveau,i915
i2c_core               30375  7
nouveau,videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit
video                  12802  2 nouveau,i915

# lsmod | grep nouveau
nouveau               675181  0
ttm                    66834  1 nouveau
drm_kms_helper         34769  2 nouveau,i915
drm                   215732  5 nouveau,ttm,i915,drm_kms_helper
i2c_algo_bit            5705  2 nouveau,i915
button                  6065  2 nouveau,i915
i2c_core               30375  7
nouveau,videodev,i2c_i801,i915,drm_kms_helper,drm,i2c_algo_bit
video                  12802  2 nouveau,i915


I've this in /etc/fstab:
# cat /etc/fstab | grep debugfs
none            /sys/kernel/debug debugfs defaults 0 0



When both i915 and nouveau are loaded in the kernel I can see this in
/var/log/messages :

I've this in debug fs:
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:04:00.0


so vga_switcheroo seems to be enabled, but if I try to switch whit this
command:
# echo "DIS" > /sys/kernel/debug/vgaswitcheroo/switch
my screen goes in a gray color state, it doesn't off, but I can't interact
with the system
 and I need to poweroff pc with power button.
I've see this in messages:
kernel: fbcon: Remapping primary device, fb1, to tty 1-63
kernel: i915: switched off


Any suggestions to make other steps to enable the nvidia card? What I can do
now?
Thanks
