2013-11-24 15:46:21 Christopher M. Penalver description I just updated to Ubuntu 11.04 Beta to find that the backlight of my monitor is off (or very low) and I can't turn it on. The backlight intensity control never worked on any previous version of Ubuntu (the Fn key controls responded, and changed a bar on screen, but never really changed the backlight). The Fn key On/Off worked before. In the new kernel, the backlight is off (or very low) by default and the controls does not work, so I can't turn it on. Now I am using the old 2.6.35-28-generic kernel to report this bug. I hope enough info on the system has been gathered. My laptop is an eMachines E725. lspci report the following about the video device: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device 0212 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d0000000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 50f0 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: linux-image-2.6.38-8-generic 2.6.38-8.42 ProcVersionSignature: Ubuntu 2.6.35-28.50-generic 2.6.35.11 Uname: Linux 2.6.35-28-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.23.
