User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.4.1)

Nvidia Quattro4 NVS, attached to two analogue or digital monitors.

system-config-display recognises the dual head capability and allows
its configuration.

Restarting the X server it aborts with the error message:

Fatal server error:
Requested Entity already in use

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install Nvidia Quadro4 NVS
2. Use system-config-display to configure for xinerama mode
3. X server aborts with the above error message

Actual Results:  The configuration file which is written by
system-config-display seems to be correct. 

The result doesn't change if you add options which are described in man,
esp. Options "CrtcNumber" and "FlatPanael"

Expected Results:  It should go into xinerama mode

Comment 1 Mike A. Harris 2004-05-10 06:06:14 UTC
The "nv" driver does not support dualhead/Xinerama at all, unless you
are using a single head plugged into the Nvidia card, and a separate
head on a different video card.  If Nvidia provides patches to the
nv driver to support this functionality however, it will be provided
in a future operating system release, and we can also review the code
changes for consideration in driver updates for existing OS releases.
