I have been loosing quite a lot of hair over this one.
I am trying to get a second x-session behaving exactly as the default one provided by ubuntu.desktop. So here is what I did:
- copied ubuntu.desktop to custom.desktop
- edited custom.desktop so the name line now reads "Name=Custom" (full content pasted below)
When I log with the ubuntu session from lightdm login page, everything goes as expected.
But if I try to log with custom, I am ending up with a wallpaper only (no side bar, not top menu, no way to launch a GUI terminal).
I cannot figure out what is special about ubuntu.desktop, that custom.desktop fails to replicate ?
custom.desktop
[Desktop Entry]
Name=Custom
Comment=This session logs you into Ubuntu
Exec=gnome-session --session=ubuntu
TryExec=unity
Icon=
Type=Application
X-LightDM-DesktopName=Unity
X-Ubuntu-Gettext-Domain=gnome-session-3.0
~/.xsession-errors
When using the provided ubuntu session, .xsession-errorsis almost empty.
When using my customsession, it fills up with warnings ans criticals, ending with those lines:
(zeitgeist-datahub:2481): GLib-GObject-WARNING **: invalid (NULL) pointer instance
(zeitgeist-datahub:2481): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failded
