Public bug reported: On raring (and precise) the display brightness keys (fn+f4 and fn+f5) on my Dell Inspiron 14z turned the brightness up and down. After a saucy upgrade this no longer happens (I don't see the popup brightness bubble either). The other, similar keys (volume adjustment, etc) still work fine.
Changing the values in /sys/class/backlight/intel_backlight/brightness works (temporarily - it gets reset after the screen lock kicks in) I tried following the instructions in https://wiki.ubuntu.com/Hotkeys/Troubleshooting but this appears to be out of date (it references /usr/share/doc/udev/README.keymap.txt which does not exist) $ lsb_release -rd Description: Ubuntu Saucy Salamander (development branch) Release: 13.10 $ apt-cache policy udev udev: Installed: 204-0ubuntu12 Candidate: 204-0ubuntu12 Version table: *** 204-0ubuntu12 0 500 http://gb.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages 100 /var/lib/dpkg/status ** Affects: udev (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1229591 Title: display brightness keys stop working after saucy upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1229591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
