Asus ACPI: Error reading brightness
Last modified: 2008-05-06 12:55:44 EDT
Description of problem: Error Message is "Asus ACPI: Error reading brightness Version-Release number of selected component (if applicable): Kernel 2.6.18-1.2239.fc5 How reproducible: Every time on logon to KDE. Steps to Reproduce: 1. Boot up into KDE (rpm kde-base3.5.5-0.2.fc5) 2. log on any account 3. Switch to a konsole screen (e.g. control-alt-f1) 4. Continuus scrolling of above error message 5. Switch back to KDE (control-alt-f7) 6. Switch back a konsole screen (e.g. control-alt-f1) 7. Message has stopped scrolling Actual results: Scrolling error message on konsole screen Expected results: No error message Additional info: This occurs on dual-boot (Windows XP/Linux FC5) Sony Vaia portable VGN-A115B. In addition, whilst message are scrolling on the konsole screen, on the KDE display screen a "brightness 7%" message block occassionally flashes up on the screen. As its format seems to be different to KDE/Fedora etc, I assume it is coming from the low level BIOS? Apparently this portable has a light sensor that is uses to control the screen brightness under Windows and I assume it is something to do with that. I've tried disabling automatic control of brightness whilst booted to Windows then booting to Linux, but to no avail.
A workaround is to put ACPI=off a a parameter in the grub conf file, which stps the message. However it, of course, stops correct power down of portable.
A friend has sent me the following ubuntu link which appears to be the same problem. https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/17125
