Installation time attempt to start up the X server for the ATI Mach 64 PCI graphics board in an AlphaServer 2100 fails to start up the X server regardless of manually entered values for various settings. DEC UNIX Xdec -screen0 1280 works fine on same hardware but RH 6.0 X server will not start up even at 1024 @8bit.
this tested fine on a lx164 with a Mach64 and XFree86 3.3.5, which is a forthcoming piece of errata. Please test again with this new X server and re-open the bug if you are still having issues. Thank you.
