Public bug reported:
On some sony vaio laptops xbacklight 1.1-1 (latest release) on Ubuntu
8.1 detects no display with a backlight. I have a Sony Vaio vgn fw290
with an ati graphics card which cannot have its backlight settings
changed. I expected that querying xbacklight would allow me to change
I am using the flgrx driver and I have the ATI mobility radeon hd 3650.
I think it is part of the Ati radeon hd 3000 series.

I tried installing radeonhd driver but after restarting it told me that
there was an error in my config file. I'm assuming that is Xorg.conf
because in the direction you gave me in the link I was confused at that
part but I went ahead and made some changes.
See if I did anything wrong, I would app
In the system>adminstration>hardware drivers, it still shows that flgrx
is activated, probably due to the fact I messed up the installation
process.
I think the problem has to do with the sections in the device section of
the config file being nested.

Here is what I changed my Xorg.conf file to now:
Section "Device"
Identifier "Configured Video Device"
# Driver"fglrx"
Driver "radeonhd"
EndSection
Section "Driver"
...
Driver "radeonhd"
Option "DRI"#Only works for X1k card
Ok, it still didn't work!

System locked up the first time I restarted and open firefox to post, but I am
assuming right now that I am using radeonhd because in the hard panel it says
flgrx is deactivated right now.
I installed the brightness applet on my top panel but when i tried to change
the brightness of the screen m
I tried to test dri support by putting glxinfo | grep direct into the
terminal and got an error:
X Error of failed request: BadRequest (invalid request code or no such
operation)

Minor opcode of failed request: 19 (X_GLXQueryServerString)

So I used xbacklight -set 50, it didn't work. Using xbacklight -get, it
returned:
49.803922
49.803922
It seems like it thinks it decreased the brightness but on the display
nothing changed.

Yeah, so I can confirm the backlight doesn't work with Ubuntu's
proprietary driver (one that it installs with), fglrx, and radeonhd. The
problem is that Vista gives me twice the battery life of Ubuntu just
because it dims the backlight, Ubuntu is kind of unusable for me unless
I am on a charger.

I think this should just be an issue with xbacklight and sony laptops in
general. I have an ati card and the backlight doesn't work.
