    Default intel 945 GM issue on tablet pc

    Hi,

    after days of trying and upgradig to Opensuse 11 I'am daring to write here and ask for help. I am stumped at all.

    I try to switch my Fujitsu-Siemens (FSC) Lifeboo P-1610 to Linux.
    The only problem is the display.

    According to Fujitsu P1610 Graphics Card -- Intel 945GM Suse should support the display. I followed all instructions but it stays at 1024x768.

    My "/etc/X11/xorg.conf" contains this
    Code:
    # SaX generated X11 config file

    my /etc/sysconfig/videobios contains the lines
    Code:
    VIDEOBIOS_PATCH="yes"
    VIDEOBIOS_PARAMETERS="58 1280 768"
    and this works because the output of "915resolution -l"
    Code:
    Intel 800/900 Series VBIOS Hack : version 0.5.3

    Mode 61 : 1280x770, 16 bits/pixel
    Mode 62 : 1280x770, 32 bits/pixel
    but SaX2 constantly keeps 1024x768 resolution

    and this doesn't surprises because "xrandr" outputs:

    I tested many other tips on the internet but nothing helped.
    So could anybody give me a hint or even tell me the right terms to google for?

    kind regards

    Hey,

    the problem is solved.
    After Hendrik gave me the Lifebook I tried a lot of different possibilities to configure the resolution. The most promising method of resolution i traced was to change the VIDEO BIOS with 915 resolution.
    But searching for the problem in the configuration was the basic error...
    To cut a long story short: I finally checked the BIOS for wrong settings and tried to set "Compensation" in Advanced->Video Features to "Enabled". Now it works...

    with kind regards

    Bastian Neubarth

    @Hendrik: Thank's for the coffee
