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. I'll forward this, and see if he is willing to test it. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
