Alright, thank you for setting me straight.

OK. 

I have a Sun Blade 2000 here with dual 1.2GHz processors, 2 x 73GB FC-AL
disks, 4GB of RAM and a XVR-500 graphic adapter. I am quite happy with
the machine, but for one very small problem. 

It seems that the XVR-500 console driver has a few problems. If I use
the X11 fbdev 0.4.2 driver with xorg-server 1.7.7, in 8 bit colour
depth, the X11 display looks quite corrupted. I have checked and the X11
server is definitely running in 8 bit depth, same as the console. I am
using the machine in 1600 x 1280 @ 76 video mode, set from PROM. After
exiting from X11, console gets restored normally, everything works, I
just get a severely corrupted display - but I can move the mouse and use
the keyboard to log in as normal. Any ideas why what might be wrong? 

As a temporary workaround I just log onto the Blade via GDM from my
laptop and everything looks OK in 24bit @ 1600x1200. 

I cannot even get the X11 fbdev driver to start in 24 bit as the X11
fbdev driver fails with errors. Is it even possible to force the PROM to
start in 24 bit depth? 

Perhaps I could do a nouveau and find how how the XVR-500 graphic
adapter works? Just thinking things out here.
