    Setting that option in xorg.conf worked! Thanks!

    Re: ThinkPad T410 Screen Brightness

    I have a similar problem with my Optimus T510 (set to Integrated graphics only): setting the brightness within the session works fine (even without the driver option in the xorg.conf), but on session start it's always at 100% (burning my eyes away ).

    Any ideas?

    The above workaround of changing the brightness from tty1 as well the solution to add brigtness entry under Devices section of xorg.conf file works well.

    I am using 10.10 on T410s.

    This worked for me. Also the FN-HOME/END keyboard brightness adjustment works well now too. Thanks.

    A temporary workaround, just switch to text console by "ALT-Ctrl-F1", adjust the birghtness there and then switch back to graphics console by 'Alt-Ctl-F7".

    Hi,
    I am trying to troubleshoot brightness control on an iMac with the same graphic card as the t410. Could you tell me what driver you used before installing the nvidia drivers (they don't exist for ppc machines).

    Having a similar problem with a Thinkpad T530 in 12.10. There is no xorg.conf anymore so I can't apply that solution. Manually adding it didn't work either. Any other ideas?

    Try it this way (in German, but I hope you get the point).
