I'm running RHEL3 WS u4 (installed as u4, rather than an upgrade from <=u3)
on a Dell Optiplex GX280.
I recently upgraded from a 17" monitor to a Dell 2001FP LCD. In addition
to this I also got the Dell DVI adapter card to provide DVI output (has
"Silicon Image" written on it). This is not a graphics card in its own
right, but simply a card which sits in the AGP socket on the motherboard
and presents the DVI output of the graphics chip on the back panel.
RedHat uses the VESA driver to drive the graphics chip and works well with
the analogue output to the LCD. However, plugging in the DVI card only
gives an output works during boot. The boot screen appears, grub appears,
the kernel boots and appears and the initial login prompt appears until X
starts. At which point the display goes blank and the monitor flips into
powersave mode. It does not display an "out of range error" for refresh or
mode. I'm running KDE.
As I said, I can drive the monitor perferctly well at 1600x1200 with the
analogue output, I just can't get X with the DVI card in and using that.
Does anyone know why this the case and what I might be able to do to fix
it?
