[Bug 36885] Re: Asus laptop hangs on TFT/VGA video switch (Fn-F8)

[mach6]

[PARTIALLY RESOLVED]

I am running Ubuntu 8.04 with up-to-date 2.6.24.23-generic SMP kernel,
on an Asus W7J.

I' ve found a partial solution for Fn+F8 key that works for me, but I
need more help to close definitively the problem.

After some searches (over nights)....the solution for me is to disable
"video" module :

sudo rmmod video

and then

sudo su

echo 5 > /sys/devices/platform/asus-laptop/display

EUREKA!!!

My Desktop is on TV screen with wonderful colors and simultaneously on
my laptop-display.

But that's not the real solution.... : - (((

When I did in console:

(as root) echo 1 > /sys/devices/platform/asus-laptop/display ---> ONLY
laptop-display at correct resolution working!!!

(as root) echo 5 > /sys/devices/platform/asus-laptop/display --> not
LCD+TV with correct resolution as I expected, but LCD at correct
resolution and TV in BLACK and WHITE at little resolution (I think
640x480)

Notes: After restart of X the problem is solved....but only for the first time I pass "echo 5 > /sys/devices/platform/asus-laptop/display"
...then the same situation descripted above.

I hope my step over is useful for someone, but I need help to completly
correct this bug.

Thanks all for consideration.

I'm sorry for my bad english

Good day
