Thread: T61 opensuse 11 - brightness (fn) keys don't work correctly

  1. #1

    Default T61 opensuse 11 - brightness (fn) keys don't work correctly

    I am running 11 GM on my T61. I use the Fn+brightness keys to adjust brightness and they don't work correctly. I'll press up on brightness and the OSD shows it going down and vice-versa. Also, when plugging back into a dock after going mobile, the brightness doesnt' go back up to 100% as expected.

    Anyone know of fixes for this or do I need to open a bug? Seems like a pretty large issue to have made it through the Alphas and Betas.

    If you installed via the 1cd livecd's you may want to use the dvd image and see if it helps....on my dell laptop function f8 is not switching to the external monitor when docked...I filed a bug on it.

    On my T61 the Fn-keys seem not to work at all. Screen brightness is all the way up all the time. There is no OSD.
    If I pull the plug of the power adapter though, the screen dims a little.

    Surprisingly, the Fn-keys work correctly when the GRUB menu is displayed but stop functioning when OpenSUSE 11.0 runs.

    I don't know how to file a bug but I think I'll have to find out.......

    When I open a console and run

    xbacklight -set 20

    the screen dims correctly.

    xbacklight -set 100

    brightens it again.

    At least a workaround.
    I found this on the Linux-Thinkpad mailing list.

    There was an ongoing problem with thinkpad Fn keys & buttons on the T60/61 and related Lenovo laptops in the betas & RC1 (see bug 382855). While there was some improvement in the thinkpad buttons issue (e.g., volume & mute were fixed in RC1), a number of the Fn buttons were left unfixed before the public release of 11.0 since they were probably deemed not to be show stoppers. The good news is that there is already an open bug on this, so the devs know about it. You can update the bug as not working in 11.0 and add yourself to the e-mail list to follow the problem (the log-in for bugzilla is the same as for this forum btw).

    There have been a number of these types of bugs in testing beta 3 & RC1 on my T60 that have lead me to at least wait a bit for some fixes as updates before jumping from 10.3.

    See if installing the hotkey rpm from Yast Software Management fixes the problem.

    I'm not sure if there's a hotkey rpm suitable for my Thinkpad.

    On my Inspiron 1525, with 11.0 the brightness keys and some other FN-Keys don't work.
    I installed a 10.3 system in parallel, and all the FN keys work. I double checked that the same keyboard layout is used.
    So I think it's a 11.0 bug.

    On my Thinkpad T61p, the LCD dims and brightens depending on whether it is active or not (in both Gnome and KDE4,running on AC or battery).This is done automatically by the powersave software.I have not used all the function keys, though I know that Fn(F4) does suspend and resume. I have another problem, not related to the functions keys, but the wireless antenna button. It does not come come on when connected to a wireless network. This used to work on Fedora 9. I wish I could get it working, though it is not a big deal, it would be nice to have it.
    I'm still looking for the perfect distribution for my laptop, but I like Suse and know that its developers are constantly working on making it the best distribution for laptops, so I'll wait.
