Framebufer - jak zvysit refresh

[Petr Simek]

Zdravim,

rozbiham si na svem novem stroji X (ATI RAGE128) a tedy i framebuffer.
Precetl jsem Vesa-FB howto a X mi bezi, ale na 48.2kHz/59.8Hz pri 1024x768 
coz je pro mne prilis malo - ve W98 to udela v pohode 1152x864-100Hz .

Jenze at s tim zapolim jak s tim zapolim nic se nedeje. V X86config mam:

Section "Monitor"
   HorizSync   30.0-95.0
   VertRefresh 50-160
   Mode "fb1024x768"
      # D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz
      DotClock 78.654
      HTimings 1024 1056 1184 1312
      VTimings 768 772 776 792
      Flags    "-HSync" "-VSync"
   EndMode
EndSection

Section "Device"
    Identifier  "My Video Card"
    VendorName  "Unknown"
    BoardName   "Unknown"
    #VideoRam    8192
    # Insert Clocks lines here if appropriate
EndSection

Section "Screen"
    Driver "fbdev"
    Device "My Video Card"
    Monitor "My Monitor"
    Subsection "Display"
      Depth    24
      Modes    "fb1024x768"
      Virtual  1024 768
      ViewPort 0 0
    EndSubsection
EndSection

a nic. Rozliseni to ma, ale refresh neodpovida. Zkusil jsem tedy fbset.
Do /etc/fb.modes jsem dal :

mode "test"
    # D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz
    geometry 1024 768 1024 768 24
    timings 12714 128 32 16 4 128 4
endmode

a prikaz 'fbset -v -a test' vypise :

Linux Frame Buffer Device Configuration Version 2.0-pre (28/10/1998)
(C) Copyright 1995-1998 by Geert Uytterhoeven

Opening frame buffer device `/dev/fb0'
Reading mode database from file `/etc/fb.modes'
Using video mode `test'
Setting video mode to `/dev/fb0'

jenze se nic nezmeni ?!@ . Zkratka nenasel by se nejaky dobrodej, ktery
by mi poradil co kam napsat a jaky prikaz spustit abych mel refresh na
vyssi frekvenci ? (na 59.8 se neda koukat pri 1024x768) Nebo rovnou
jaka cisla pouzit pro 1152x864-100Hz kdyz uz mam ten dobrej monitor . :-)

S pozdravem
