Bug description:
In Oneiric, when logging in remotely with XDMCP + VNC and selecting
the "Ubuntu" session, Unity fails to properly fall back to Unity 2D.
Instead the user is presented with just their desktop background, with
no widgets of any kind. Sometimes a Nautilus-like menu bar briefly
appears at the top and then disappears (i.e., File, Edit, View, Go,
Bookmarks, Help). Occasionally the menu bar remains visible and/or the
user's desktop icons can be seen. In no case does the user ever get a
functional Unity 2D session with the launcher.
Manually selecting the "Ubuntu 2D" session results in a functional
Unity 2D session as expected.
Replacing /usr/lib/nux/unity_support_test with a symlink to /bin/false
causes the "Ubuntu" session to fall back to a functional Unity 2D
session as expected. So probably the problem occurs in
/usr/lib/nux/unity_support_test.
I have attached the .xsession-errors from an "Ubuntu" session login
attempt.
Repro steps:
1) Enable XDMCP login in /etc/lightdm/lightdm.conf by adding:
[XDMCPServer]
enabled=true
2) Install xinetd and vnc4server and set up a VNC port to use XDMCP
login by creating a file like this in /etc/xinetd.d:
service Xvnc
{
type = UNLISTED
disable = no
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/Xvnc
server_args = -inetd -query 127.0.0.1 -once -geometry 1920x1200 -depth 24
-securitytypes=none -DisconnectClients=0 -NeverShared
port = 5901
}
3) Restart xinetd & lightdm services.
4) Connect to the chosen VNC port (5901 above) with Vinagre.
5) Login with the "Ubuntu" session selected.
Actual Behaviour:
6) The user is presented with a nonfunctional session.
Expected Behaviour:
6) /usr/lib/nux/unity_support_test should detect that the X11 display
does not support COMPOSITE and GLX and should exit with error code 1
so that Unity 2D is used.
