When the linux-image-extra package was omitted, the brightness control works with v3.7-rc3-raring, but when linux-image-extra was included the brightness control did not work with v3.7-rc3-raring. I suspect that when the linux-image-extra package is missing the display driver does not actually work and the brightness control uses some other magic (maybe BIOS?).
With v3.7-rc4-raring the brightness control works with linux-image-extra package being installed. Thus it seems the bug was fixed in between v3.7-rc3-raring and v3.7-rc4-raring. I did not install any linux-headers packages in any case when I tried mainline kernel builds. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074823 Title: [HP Compaq 2510p] Brightness control FN-hotkeys have no effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1074823/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
