myunity reports unity is in 2d mode when it isn't

[Anton Piatek]

Trying to use myunity to disable the seconds launcher bar on my second screen, it pops up message saying that Unity is running in 2d mode, and most options are greyed out.

I believe unity is in 3d mode because neither the user or system lightdm config mentions 2d, and because of the following data I have tried to gather:

$glxinfo | grep rendering
direct rendering: Yes

$/usr/lib/nux/unity_support_test -p
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 7300 LE/PCIe/SSE2

Thank you for taking the time to report this bug and helping to make ubuntu better.
According to your findings, looks like you ar actually using unity-2d. You can infer this assumption from ps:

$ps -ef|grep "meta\|unity\|compiz"
anton 5795 5709 3 11:20 ? 00:00:47 unity-2d-shell
anton 5796 5709 1 11:20 ? 00:00:17 unity-2d-panel

unity-2d-{shell,panel} are binaries related to unity-2d, hence I guess myunity is right saying you that myunity is running in 2D mode.

I'm closing this bug as invalid. If you think this is wrong and it's an actual bug, please feel free to revert its status and reopen it to investigate further.

[Anton Piatek (anton-piatek)]

Are you sure that is enough to determine it is 2d? Others on #ubuntu+1said that they had unity-2d process running, and that the presence of the compiz processes meant that it was running 3d:
anton 10340 10336 0 11:32 pts/0 00:00:00 /bin/sh -c compiz --replace
anton 10342 10340 32 11:32 pts/0 00:03:18 compiz --replace
anton 10379 10342 0 11:32 ? 00:00:00 /bin/sh -c /usr/bin/compiz-decorator

Please, would you issue this command in the terminal:

echo $DESKTOP_SESSION

and paste the output here?

$echo $DESKTOP_SESSION

Thank you for your follow-up.
This is pretty weird, since looks like you are actually using a unity3d session, despite unity2d-related processes are running on your system.
I'm seeing right now that a "/usr/bin/unity --reset" command has been issued. Did you tried to respawn a unity session manually?
Please, would you paste here the result of "ps -ef | grep unity" immediately after a reboot?
Since we need to investigate further about this bug, I'm reopening it right now.

[Anton Piatek (anton-piatek)]

Ok, so I think it is something rather odd on my system. Rebooting produces a similar result, but I do get and X crash (possibly in the nvidia driver) and a unity crash on logging in. both recover and let me continue, but I think it is dropping me down to a partial unity-2d interface.

I have just disabled acpi with acpi=off on my grub options to work around another issue where my cpu was stuck at 800mhz scaling. This time, I no longer got crashes on login, and myunity now sees me as not being 2d.
ps also no longer shows any unity-2d processes.

If VNC is running you could have 2D running even if the console is 3D...
