Hi Adaplas,

I am unable to activate the X server on my Desktop after inserting the
i810fb driver as follows.

	modprobe i810fb vram=2 xres=1024 bpp=16 hsync1=30 hsync2=55
vsync1=50 	vsync2=85 accel=1
After that I get no GUI on the Desktop & when I say startx, I get some
errors & I have attached the relevant Xserver_log file as well as the
configuration file to this mail.

I am specific to i810fb driver as I want to rotate the screen using X
server

After that on trial basis when I modies the Device section as follows,
trhe GUI is working with a light shift in the screen. I thing that can
be rectified with modification is resolution but what is "fbdev" which
made my GUI work.

	Section " Device"
		Identifier "videocard0"
		Driver "fbdev"
		VendorName "videocard vendor"
		BoardName "Intel 810"
		VideoRam 16384
	EndSection

How do I solve this problem? 
Thanks in advance.

Regards,
Mukund jampala
