Is this supposed to be fixed? I have XPS13 (Feb 2013 edition, i7) with latest saucy 3.11.0-15 and problem is still there. Last kernel that works properly is
Linux slap 3.8.0-29-generic #42-Ubuntu SMP Tue Aug 13 19:40:39 UTC 2013 which I am running right now, while the system is upgraded to Saucy and the kernel is one used in the 13.04 series. To be precise: the brigthness buttons make the brightness bar appear on screen and go up and down correclty, but actual brightness is always at the lowest possible level, never changes. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1163720 Title: Brightness control broken on XPS13 and 3.8.0-16, 3.8.0-22 and 3.11.0-12 Status in The Linux Kernel: Incomplete Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Precise: Fix Released Status in “linux” source package in Quantal: Fix Released Status in “linux” source package in Raring: Fix Released Status in “linux” source package in Saucy: Fix Released Bug description: Since 3.8.0-16, the brightness control doesn’t work anymore. The popup is displayed, so the shortcut keys do work correctly, but it has no effect on the actual brightness of the screen. Switching back to 3.8.0-15 solves the issue.
