This might be related: On Intrepid after upgrading from 8.04 (after upgrading from Xubuntu 7.10 IIRC), on an IBM x40.
Sometimes when I try to change the illumination (fn+home or fn+end on the x40) nothing happens at first. Sometimes the "illumination bar" shows up in the midle of the screen, sometimes it does not. Usually, after a while (up to minutes), the system "catches up" and replays the whole change in illumination. The "illumination bar" also someimes gets stuck on and stays on the screen for extended periods of time. And I have random changes in illumination while on AC. -- Keyboard unresponsive after changing illumination of screen via keyboard https://bugs.launchpad.net/bugs/292612 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
