I have a dual video adapter system:
Primary: ATI Rage 128
Secondary: NVidia Geforce2
System boots on R128 and then runs X on Geforce.
If I run ddcprobe from a virtual console (on R128) it
works fine. If I run it on an xterm it fails (see
below).
What should the correct behavior be? I would have
expected it to give me the DDC data for the NVidia
card/monitor that it is the active console.
nvidia vs nv driver doesn't make a difference. Same
results for both.
ddcprobe not working wouldn't be a big deal except
that Redhat's redhat-config-xfree86 calls ddcprobe.
Because of the error the Probe button in this app is
disabled. Without the probe button there is no easy
way for a user to rewrite the XF86Config file after
changing a monitor.
ddcprobe is using VESA support to the get the DDC
data. Should the VESA vectors be modified to point to
the Gefore when X is activated on the Geforce? Or
should ddcprobe be modified to use another scheme for
getting the ddc data?
