[Linux-fbdev-users] ATI Mach64CT

[Henry J. <sl...@ya...>]

Hi there,

I am trying to install qt/embedded on my Debian box, after compiled it, =
I started the sample program and found the screen is "in green". The =
sample program requires a 16-bit color, I tried 1024x768 and 800x600, =
both are in the same color tone.

It's a PentiumPro 200 box, the display adapter is based on ATI Mach64CT =
chip. The machine runs Debian potato with kernel 2.4.19, with atyfb =
compiled as a loadable module.

I was trying to test it with X frame buffer to see if this is a problem =
of qt or atyfb, but I don't know how to change the color depth and the =
resolution for X.
My best guess is that the rgba 555 should be 565 for that display card. =
I try to set rgba to 565 with setfb, it does not work. setfb --info =
still shows rgba 555.

How can I solve this problem? Thanks in advance.

Henry
