Same (or similar) problem with ASUS X5DIJ running ubuntu-10.04-desktop- amd64. Strange, since worked OK with 9.10 64 bit (ubuntu-9.10-desktop- amd64).
Neither the function keys nor the panel applet actually affects the brightness. The power management centre also has no effect. Brightness-changing commands, issued using the function keys, appear to get stacked, if issued in (not particularly) quick succession. I surmise this because the brightness slider bar graphic randomly shows on the top-right of the screen, several times, long after I have ceased playing with the keys. Other funny things: when I use the panel applet, I cannot slide it with the mouse button, only by using the keyboard's up and down arrow keys, and sometimes, when I have clicked upon the applet, the slider bar shows at the top left of the screen, instead of above/below the applet. I had allowed the 9.10 to 10.04 upgrade to run, which seemed to break brightness control, as described. Subsequently, I resorted to a clean 10.04 installation, from the ISO image, but the behaviour remained the same. Thanks in advance to anyone who works to resolve this. -- Cannot change brightness Asus UL30VT https://bugs.launchpad.net/bugs/542296 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
