@xiaq Ok, from your description we can confirm that in 10.04, thinkpad_acpi driver is not loaded, so the hardware is behaving in its "default" way. This could be programmed in the firmware.
thinkpad_acpi driver also controls many other things, such as brighness adjustment, radio (wifi/bt/wan) toggling, and possibly the external video switch and fan control. Does anyone facing any malfunction of above in 10.04 since in that version the driver is not loaded by default. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/595896 Title: Thinkpad SL510 Mute button not working -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
