Hi,
    I am trying to configure framebuffer for X on redhat linux 7.2 .
I have done the following things.
1. I installed the rpm XFree86-FBDev-3.3.6-42.rpm and XFree86-fonts-4.2.rpm.
2. Created a softlink :
    ln -sf /usr/X11R6/bin/XF86_FBDev /etc/X11/X.
3. In the XF86Config file, i set the :-
    Driver    "fbdev"
    Modes  "default".
    Depth    8
    FontPath   "unix/:7100"
 
Also using 'make menuconfig', in 'console drivers', enable:
  [*] VGA text console
  [*] Video mode selection support
  [*] Support for frame buffer devices (EXPERIMENTAL)
  [*] VESA VGA graphics console
  [*] Advanced low level driver options
  <*> 8 bpp packed pixels support
  <*> 16 bpp packed pixels support
  <*> 24 bpp packed pixels support
 
With all these set. I start the startx. And it gives the following output:
************************************************************************************
