Hi,
Coming from #176888 which has been marked duplicate of current issue :
Hardware : sony Vaio BZ11XN (Intel GMA X4500MHD).
I confirm, on latest Intrepid (as of 2008-08-30), that the xrandr manual-call
is *needed* to be able to use xbacklight.
My Fn-keys are not working but this is another pro
Can confirm this problem for an x61s. The workaround with reloading
thinkpad_acpi with "brightness_enable=1" and then writing the number in
the concerning proc file worked for me. However the adjustments keys
still don't. Please fix this.

I'm not sure if this is related, but on the transition from alpha6 to beta, I
also lost the display turning off after the screen saver. This is on a T61, set
with screensaver after 5 minutes and screen off (in power management) after 10.
Can anyone confirm if you have this same new behaviour?

Same problem here on my R61. Brightness stopped working after a Hardy
upgrade a few days ago.
Also, when I press the brightness keys there is a 3 second delay before
the indicator pops up - the level bar goes up and down but the
brightness does not change.
Whenever I press the brightness keys I g
I'm having this same problem with the backlight as I already commented in
#201533.
I got it working with xbacklight by changing the BACKLIGHT_CONTROL from kernel
to native, whatever that means:
$ xrandr --output LVDS --set BACKLIGHT_CONTROL native

Some more info, if I load thinkpad_acpi with brightness_enable=1 set, I
can control the brightness by echoing values into
/proc/acpi/ibm/brightness. e.g.
echo level 10 > /proc/acpi/ibm/brightness

I just looked in the dmesg output when loading the thinkpad_acpi module
and spotted this message. Maybe it helps?

Nope, wasn't that change, instead this one:
ACPI: video: Ignore ACPI video devices that aren't present in hardware

I built the latest kernel without that commit, and now the backlight

Hi,
Yes, it happens with 2.6.24-11. The dimming does not work by using the
power preferences or the keys. I also tried xbacklight, it also doesn't
work.

Hi Dan,
I assume you are then having issues when using the 2.6.24-11 kernel? If
you try to dim using System->Preferences->Power Management does that
work? Per the kernel team's bug policy, can you please attach the
following information. Please be sure to attach each file as a separate
attachme
I'm seeing the exact same behavior using the i386-build on the same
machine. Also using xbacklight from the command line is ineffectual.
