[X2Go-Dev] Bug#150: Cinnamon 2.2 does not work

Sat Aug 9 19:49:10 CEST 2014

I just tested Cinnamon 2.2.13 and it does not work properly with X2Go.

Basically, Cinnamon resorts fo "fallback mode", which is not the same
as Cinnamon2d.

More details are below. Note that GLX is enabled, and I ran the
"Custom Desktop" command: cinnamon-session-cinnamon2d

----

When I connect, only gnome-panel is running. (Basically,
gnome-flashback is running, although package gnome-session-flashback
is not installed) It is very different from cinnamon2d, which works
locally, and there are many bugs in this version of
gnome-panel/gnome-flashback. For example, you cannot even set a
desktop background using the GUIs.

I also see a dialog with the text:
Do you want to restart Cinnamon?
Cinnamon just crashed. You are currently running in Fallback Mode.

If I click yes, the dialog comes back up. If I click No, I the dialog
closes, and the session is usable, but it's very buggy for
aforementioned reasons.

This is just a VM I setup for the specific purpose of testing Cinnamon
compatibility with X2Go.

I have the GLX extension enabled on my test system
(/etc/x2go/x2goagent.options has the line to disable GLX commented out)
- Linux mint 17 qiana (based on Ubuntu 12.04 trusty) 64-bit
- All latest level 1, 2 and 3 OS updates installed.
- cinnamon version 2.2.13
- Custom Desktop specified in x2goclient: cinnamon-session-cinnamon2d
- x2goserver & x2goserver-xsession: 4.0.1.15-0~847~ubuntu14.04.1
- nxagent & x2goagent: 2:3.5.0.27-0~446~ubuntu14.04.1

I've attached the contents of my .xsession-x2go-errors file.

Note the following session files:

(cinnamon:5302): Gdk-ERROR **: The program 'cinnamon' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 172 error_code 16 request_code 147 (GLX) minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
