Description of problem:
Nvidia Quattro4 NVS, attached to two analogue or digital monitors.
system-config-display recognises the dual head capability and allows
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):
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
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.
