[bug #25534] remote execution of applications via ssh -X doesn't work

[Sebastian Reitenbach]

Follow-up Comment #12, bug #25534 (project gnustep):

I've here my notebook and the desktop, both i386, and just retested again.


 * I ssh from desktop to the notebook
 * throw away all my defaults, rm -rf ~/GNUstep
 * start Gorm, that works well then via ssh and also works well locally

then test the other way around:
 * I ssh from notebook to desktop
 * throw away all my defaults, rm -rf ~/GNUstep
 * start Gorm, and it does not work via ssh, but works well when using it
locally

problem:
 * The main menu is not usable, nothing happens on clicks
 * right click in a window, then the context main menu appears
   a) not below the mouse, but on the left border of the screen, and is also
not usable
 * pulldown menus seem to have the same problems, 
 * buttons, and switching between pallets works

setup on the notebook and desktop are the same:
openbsd 4.4, i386
gnustep-make-2.0.8
gnustep-base-1.18.0p0
gnustep-back-0.16.0 (using xlib)
gnustep-gui-0.16.0
gnustep-gorm-1.2.8
libffi-3.0.8

on the desktop, there is a ati-radeon driver used, on the notebook intel.
display resolution on the notebook: 1280x768
display resolution on the desktop: 1920x1200

on both sides, in sshd_config, X11 forwarding is configured like this:
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes

Then I tried an xhost + on the notebook
again logged into the desktiop from the notebook
and change the DISPLAY variable to <notebookIP>:0.0 and started Gorm, and it
started and was behaving well.
however, when I logout, and login again, without changing the DISPLAY
variable, then start Gorm, it doesn't behave correctly anymore.

below the log output when starting it, and clicking on the main menu once:
Xlib:  extension "MIT-SHM" missing on display "localhost:10.0".
