Bug#625211: linux-image-2.6.32-5-amd64: Can no longer control backlight

Followup-For: Bug #625211

No, with the radeon driver it works, sorry for not having checked that.
There  is already a bug open against fglrx-driver, as brightness is concerned:
719536.
The problem remains that one need to specify the kernel attribute in the grub
configuration file, it would be nice if that could be handled during
installation.
Thanks, Carlo.

Bug#625211: linux-image-2.6.32-5-amd64: Can no longer control backlight

2013-08-13 Thread Carlo Marchiori
Package: src:linux
Version: 3.9.8-1
Followup-For: Bug #625211

Dear Maintainer,

there still problems related to backlight. At first I could not control it at
all. Then, following forums and wikis on the net i tries to pass the
acpi_backlight=vendor parameter to the kernel, and know it work... a little
bit.

What works is that all methods, the keyboard special keys, xbacklight, gnome-
control-center, all udpate the same file, in my case
/sys/class/backlight/samsung/brightness.

But. First that file is reset to the maximum value at every restart. I worked
around this by echoing something into it in /etc/rc.local.

Second, and worst, when I change the file value at runtime (by any of the above
methods), the value is applied... sometimes. I mean, I keep changing the value
and once in while the brightness changes, after 2, 5, 10 seconds, and I have to
be lucky that it happens at the right brightness. If you just change the value
without keeping trying, the value is not usually applied.

Regards, Carlo.
