Right, the current hal patch only fixes this for the LENOVO series, since I had no other data from the bug trail. On the other hand, Adam Conrad has an IBM T43 without hardware brightness buttons, and current edgy works fine for him.
So I am reopening this for edgy+1. Everybody: Please check if this affects you, and give me the output of lshal|grep smbios.system ** Changed in: hal (Ubuntu) Status: Fix Released => Needs Info Target: ubuntu-6.10 => None -- Screen brightness buttons don't work properly on Thinkpad Z61T https://launchpad.net/bugs/61184 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
