Joseph, I have here a kind of mystic.
I have just restarted my system. Now it is able at random to switch trough the values for the backlight. Everytime I strike a key it goes go maximum, when I wait some seconds it is going down the values step my step, until the monitor is black. I am since some weeks on raring. There was no special bughandling on linux bugtracker upstream. This is the first time I observe this behaviour. The only things that have changed are a actualisation of libfree...? from yesterday, and I have installed some alien packages(converted with alien to .deb) which are color associated. cinepaint-0.25-14.2.x86_64.rpm liboyranos0-0.9.1-33.1.x86_64.rpm libXcm0-0.5.1-21.1.x86_64.rpm all from http://download.opensuse.org/repositories/medical/openSUSE_12.2/x86_64/ designed by Sascha Manns There where also some trouble with mounting during this reboot(have not seen exactly). ------------------------------------------- Anyway of the long story, the kernel3.7.0ubuntu flavor seems to be able to control the backlight in any random way. ** Tags added: raring ** Description changed: I could not adjust the backlite of my HP 655 laptop. Original vendor website: http://h10010.www1.hp.com/wwpc/us/en/sm/WF05a/321957-321957-64295-3740644-3955548-5225017.html?dnr=1 The gnome-brightness applet is startable and the keys for brightness adjustment (F2 for less and F3 for more) are recognized by the system and can set the Software values, but also there is no real effect. A check of /sys/class/backlight shows a redirect to acpi_video0 which contains different entries like files for brightness. So it is a bug of the type: "Backlight control does not work, but there are entries in /sys/class/backlight" The laptop was originally delivered with a SUSE Linux Enterprise desktop 11 on Service Pack 2, which has contained kernel 3.0.x. On this kernel version the Backlight was working. Unfortunally the SLED 11 SP2 was a obvious adapted one by HP with poperitary Software components. Following this the vanilla 3.0.x kernel may also not be able to handle the backlight with success.
