I have the same issues with backlight and I would like to stress that this issue is not specific to nVidia adapters, but also Intel.
Following the instructions in this bug, I've managed to make backlight brightness adjustable via Fn-Up/Fn-Down combination and via brightness applet, but Fn-F5 (toggle backlight) and Fn-F9 (toggle wireless) still does not work. Apart from that, the "sticky Fn key" problem is solved only partially and sometimes it still sticks. The sensitivity of Fn-Up and Fn-Down (brightness) is twice lower as the sensitivity of Fn-Left and Fn-Right (volume) which is also not very convenient. Other keys like Fn-F5 (toggle backlight) and Fn-F9 (toggle wireless) still doesn't work, but now they are not reported in /var/log/kern.log Unfortunately, non of the described solutions helped to accomplish this on it's own, so I had to use the combination of them: added setkeycodes to bootmisc.sh, patched the kernel with above patch and added acpi_backlight=vendor to kernel params. I didn't find anything particulary interesting in my logs, but I can provide them upon request. Hope this info helps to fix this issue. -- brightness hardware control on Samsung R510 doesn't work https://bugs.launchpad.net/bugs/297962 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
