Hi/True Color mode for X ! please help

["Linh Dang" <Linh.Dang.linhd@nt.com>]

I have just installed ham from SLS. Everything is fine except X
in Hi (16bits) or True (24bits) color.

I have a Sony CPD 200sf and a PCI ATI 3D Rage II+ with 8Mb on board.
I have an excellent 1280x1024@74Hz in 8bits depth but when I switch to
a 16/24/32 bits mode, I get an 1-inch-wide column of noise at 1/4 of 
the screen on the left side. All the other area of the screen is OK 
except for that column.

- I configured X with XF86Setup and tuned it with xvidtune.
- Windog95 has no problem in 1280x1024@74Hz in 16bits.

Please Help!
