# Nemate nekdo skusenost s grafikou ET4000W32 alebo TGUI32DGi na linuxe ? Obe
# by mali byt podporovane v XFree86-SVGA a aj su, ale nejde mi viac ako 8bpp,
# aj ked kamosovi na woknax hej. Mne pise, ze :
# SVGA: Linear addressing is required for 16bpp
# Kde to mozem zapnut ? Da sa to? Alebo je to hardware problem ?

Zdravim,
  ach jo:

`man XF86Config`
  ...
  The Device sections are used to define a  graphics  device
  (video  board).   More than one Device section may be pre­
  sent in an XF86Config file.   The  entries  available  for
  this section are:
  ...
  Option "optionstring"
    This optional entry allows the user to select cer­
    tain options provided by  the  drivers.   Multiple
    Option entries may be given.  THE SUPPORTED VALUES
    FOR OPTIONSTRING  ARE GIVEN IN THE  APPROPRIATE  X
    SERVER !!MANUAL!! PAGES  AND/OR THE CHIPSET-SPECIFIC
    README FILES.

  => `man XF86_SVGA`

  ...
  Option "optionstring"
    allows the user to select certain options provided
    by  the  drivers.  Currently the following strings
    are recognized:
  ...
    linear - Attempt a linear mapping  of  the  frame­
             buffer  into high memory. Currently only supported
             for some Cirrus  and  oti087  configurations,  the
             ET6000,  the  ET4000W32p  rev  C  and  D  and  the
             ET4000W32i.  Automatically selected (and hence the
             option  is ignored) for the clgd5462 and clgd5464,
             C&T, NVidia, and the ARK chipsets.  This  is  also
             true for Tseng chips, except for 8bpp modes, where
             this flag allows linear mapping to be  forced  (it
             defaults to banked mode at 8bpp).

  => z toho celeho plyne, ze si vyeditujte /etc/X11/XF86Config a v
     sekce device (Section "Device") dopiste radek: Option "linear"


  S pozdravem,
