[Mageia-discuss] New install - nearly black screen after reboot - Laptop

[Renaud (Ron) Olgiati]

Reposting with a different subject line, since I found, when browsing for a 
solution, that this problem affects many more laptop models (and also other 
distributions).


A solution:

When installing Mageia (1 or 2) on a laptop, and you end up with a nearly 
black screen, and the Fn + v and Fn + ^ keys doing nothing :

Reboot with the install DVD, and go for "Upgrade Mageia"

When the install reaches the post-install config step:
Go to Bootloader => Configure => Next

You are now shown the various entries of the Grub menu and can modify them one 
by one.
Just do that, adding acpi_osi=Linux to all the 'Mageia' lines.

If you know that your laptop has this problem, you can do all this as part of 
the original Mageia install process, saves time  ;-3)

Be aware that for reasons unclear, the Fn keys for more or less backlight are 
inverted: Fn + ^ for less light, Fb + v for more.
 
Cheers,
 
Ron.
