I have a Thinkpad R50e and i had the same problem as you since Ubuntu 9.04. I though that Ubuntu 9.10 would fix it but it didn't so i search to fix it myself and i find something I got on the thinkpad-acpi website and they say that we should look in the documentation "thinkpad_acpi.txt" which i find on this website : http://www.mjmwired.net/kernel/Documentation/laptops/thinkpad-acpi.txt
On line 219, it says how to enable all hotkey. Here's how i did it : $ sudo -s # echo 0xffffffff > /proc/acpi/ibm/hotkey And it works :) Now, i got the OSD for volume and brightness hotkey :) Hope this is gonna help you ;) -- [KARMIC] Thinkpad T42P volume OSD does not work https://bugs.launchpad.net/bugs/432188 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
