Hi,
I have problem in running three screens in X window with separate
session
managers. Your advices will be greatly appreciated.
I am able to run two screens with Matrox G550 with separate session
managers without any problems. I can also run the three screen
configuration
in xinerama mode, without any problem. However, whenever I try to start
session manager in the third screen, X will crash. X will also crash, if
I
try to start an X client from the other two screens, e.g., with a
"xterm -display :0.2".
The third screen is using a ATI Radeon card and a Viewsonic monitor.
When
this combination is used on a different machine as the second display, I
don't have any problem either.
I suspect I am not invoking the session managers for the second or
third
screen correctly. Currently I do
"gnome-session --display=:0.1 &"
in :0.0. (Note that it works fine for the second screen) Probably I
should
start the session managers simultaneously and before I am already inside
the
the first screen. Or there might be something else I am missing. Any
comment is welcome. However, using xinerama is not an option.
I am running a dual MP2000 Tyan Tiger m/b with 1 Gb RAM. The
XF86Config-4 file and the output of xdpyinfo are enclosed below.
Thanks a lot in advance.
