Assuming this is the same bug that I see on my Acer Travelmate 5735Z, it's reported as kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=31522 and was introduced after 2.6.38-rc8. The responsible kernel developers investigated this, and it turned out that on this notebook the BIOS/ACPI LBPC value is backwards: 0xff means dark here, whereas normally it means brightest, and 0x00 means bright, when it should mean dark. There are ways to work around it on this machine: either use nomodeset, or set acpi_osi=Linux and press the "Backlight Darker" key once when the screen got dark. Not proper fix has been suggested yet. m. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
