I am having trouble with Unity after an upgrade to 14.04 (and still there after another update to 14.10 which was due to me not paying attention)
I have no unity or anything else and only have Firefox because being the very nice app that it is it loaded for me to carry on where it left off.
I can drop to TTY1 and
DISPLAY=:0 unity --replace but the error message I get is
compiz (opengl) - error: FBO is incomplete: GL:FRAMEBUFFER UNSUPPORTED
What is it trying to tell me and how can I fix this?
UPDATE 1: I tried following the advice here: upgraded to 14.10 and no unity no dash but this was not the answer I was looking for.
UPDATE 2: Using
DISPLAY=:0 ccsm I was able to enable to the Unity plugin for compiz and disable Framebuffer Object in OpenGL
DISPLAY=:0 compiz then gives me the unity sidebar although the top bar is pretty limited and lacks menus etc.
