Thank you Erik. I have tried in parallel to compile the source package that I had manually downloaded (including the patch). Roughly, here (http://www.berthon.eu/wiki/foss:ubuntu:wikishelf:hal:feisty) is an history of what I executed. After rebooting, I issued the modprobe command to load the dcdbas module and added the LCD brightness applet. It did not work (I guess this is due to the problem you mentioned about the libsmbios version). It reset my brightness to the minimum and I could not changed it after. Also the applet does not show the current brightness level and is not able to raise or lower it.
I will wait for libsmbios to be backported from Gutsy. Do you know if there is already a Live CD of Gutsy that I could play with? Once again thank you for your very quick reply :-) -- Dell Laptops don't talk to HAL about brightness correctly https://bugs.launchpad.net/bugs/43572 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a direct subscriber. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
