I have an SL 510 running 10.10 and have this problem too. According to thinkwiki.com(http://www.thinkwiki.org/wiki/Category:SL_Series), SL series notebooks have Ideapad firmware, which may be a good clue for this bug. It also suggests a general solution for Thinkpad(http://www.thinkwiki.org/wiki/Mute_button) but that doesn't work on my SL 510 most likely due to the firmware problem.
However I remember 10.4 didn't have the bug. I suggest that 10.10 be marked as Milestone. To Chris Webb: "SL 410" is not really the model name. 410 just stands for a 14.1in screen. The model number is printed on the back of your notebook, like "TYPE 2847-63C". -- Thinkpad SL510 Mute button not working https://bugs.launchpad.net/bugs/595896 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
