    ACPI Problems on Fujitsu Laptop

    On my new laptop (Fujitsu Biblo NF/A70) Hardy seemed to run fine.
    Later i found that I can not adjust brightness of the screen. Neither by hotky nor by command. The brightness can be adjusted while booting. As soon as the kernel is loaded I can not adjust it anymore.
    Next thing which bugs me is the fact that KSysGuard tells me that my processors run at 800MHz all the time. KInfoCenter tells me same. The CPU Core 2 Duo T8100 should be able to reach 2.1GHz.
    When i use "powersave -r" the CPU seems to reach this speed under load. I wonder which application tells me truth. I guess the problem is that the ACPI is not recognised correctly. The whole folder /proc/acpi only contains empty files.
Working...
