original kernel: Linux tdlap6 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 2010 x86_64 GNU/Linux No screen brightness adjustment possible. Workaround: "acpi=ht"
Tested upstream kernel linux-image-2.6.34-020634rc6-generic_2.6.34-020634rc6_amd64 Screen boots to 100% brightness, even if set to minimum during BIOS post * with no boot options, hot keys activate screen brightness applet. But screen brightness does not actually change * with "acpi_backlight=vendor" option, screen brightness applet does not show up, actual screen brightness does not change Tested linux-image-2.6.32-02063209-generic_2.6.32-02063209_amd64.deb * screen brightness can be adjusted. Applet doesn't show. But fan running at highspeed and only one processor showing on my i5 !#!?! * system booted with device not found, then disk repair On Mon, May 3, 2010 at 6:48 PM, Jeremy Foshee <[email protected]> wrote: > Hi Tony, > > If you could also please test the latest upstream kernel available that would > be great.
