I'm filing this bug report (with severity minor) to see if there are any
other users with similar condition.

I have an nvidia optimus capable hardware, which I intend to make use of
for the external display (Projectors and External Monitors)

Following the howto at
http://tuxicate.blogspot.in/2013/01/optimus-and-ubuntu-1210-part-3.html

When trying to fire-up the secondary X server running with the nouveau
driver, I get the following error:

[  1006.460] (II) GLX: Initialized DRI2 GL provider for screen 0
[  1006.461] (II) NOUVEAU(0): NVEnterVT is called.

 for help.
[  1006.461] (EE) Please also check the log file at "/tmp/Xorg.1.log"
for additional information.
[  1006.461] (EE)



The full log for the secondar server is attached. Also attached is the
script and the nouveau xorg config file.

Is this a known issue on nouveau driver ???
