I have observed this problem for some time on my Dell Inspiron E1705. The few references I can find to it have a commonality of Dell laptops with NVIDIA-based graphics.
I independently bisected the regression to kernel commit b99da31ed8521eb78d5d6930f3128f8ecdb75fae. This was also indicated by Tim Gardner in this thread: http://comments.gmane.org/gmane.linux.kernel/1298379 However, the commit in question is supposedly correct but may have unmasked bugs elsewhere. Determining what this bug may be has eluded me thus far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1101919 Title: Display brightness is stuck at lowest setting on GeForce Go 7900 GS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1101919/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
