Cannot start (most) sessions with Edubuntu 14.04.1

[andygoossens]

I am having issues with the combination of BerryTerminal 20131225 and Edubuntu 14.04.1. When I try to start a session the display becomes black and only the X mouse cursor remains visible.

I see on the LTSP server that the user is actually connected and that some processes were started. But it won't go further than the "gnome-session --session=ubuntu" step. However, of all the possible sessions I have tried so far, the only ones I found working where "xterm" and "openbox" (not part of the default installation). Other sessions just hang.

Starting a PXE client in Virtualbox (connecting via host-only netwerk to Edubuntu, which is running as well in Virtualbox) works fine. Using BerryTerminal in combination with an older Edubuntu release (12.04.4) works as well.

I have no idea to fix this. It looks like I am not the only person that is affected as these reports look similar:

Think it concerns an Ubuntu/GNOME bug where it fails when connecting from a computer that runs an X server without hardware acceleration

For now:

• Stick with Ubuntu 12.x

Or install a desktop environement that doesn't use GNOME.

E.g. on the Edubuntu server execute "sudo apt-get install lxde"
And add "LDM_SESSION=lxsession" to Berryterminal's cmdline.txt to make it the default.
