Problem Opening X-Clients in Solaris

mahatma · March 3, 2006, 9:27am

Hi,

I use hummingbird exceed9.0 to open active X-Server Sessions to Solaris(Sol9 SPARC) machines. I m able to open "Solaris desktops(CDE)" for all Solaris machines except a specific machine.

Initially the XDMCP display manager chooser did not display (that) server in the list. I had to execute /usr/dt/bin/dtconfig -daemon command to get it displayed. Clicking on this opens a blank screen though.

However, I m able to invoke that server's GUI applications from a simple telnet session by

opening a passive/dummy X-Server session in my windowsXP PC
Setting the DISPLAY variable in the telnet session.
Invoking the command.

But unfortunately, I cannot live with this kind of GUI invocation alone.

Can someone help me in getting the CDE to work?

FYI. The problem occurs when connecting to that specific Solaris machine using any Xserver software, not just Exceed. This made me doubt that it had something to do with the Solaris machine.

Thanks.
M.

I happened across the following while looking at another issue - remembered your issue and thought it might help.

From sunsolve:

To run dtlogin on a headless system (a system without a frame
buffer), do the following:

copy /usr/dt/config/Xservers to /etc/dt/config/Xservers

edit /etc/dt/config/Xservers and comment out the last line
(insert the # character at the beginning of the line):

# :0 Local local_uid@console root /usr/openwin/bin/Xsun :0 -nobanner

This will prevent the console from starting an Xserver or an X-windows
display manager, but will allow X-windows applications to be run on the
system and be remotely displayed to other systems.

If you are using the XDM login manager on your system, comment out the last
line of /usr/openwin/lib/xdm/Xservers:

# :0 Local local /usr/openwin/lib/xdm/StartOW :0

This will prevent the console from starting OpenWindows.

Note: dtlogin and XDM, besides displaying the login banners on the console
of a machine, also allow remote machines to connect their displays to this
system (and also allow eXceed or other X-emulator applications to connect to
this system)

Thanks for the reply.

What is a headless system (you mean without a video card/monitor?). Yes my server is headless! Anyhow, I was already able to access Xappls by opening dummy Xserver session in my PC)...

The contents of my /usr/openwin/lib/xdm/Xservers file:

:0 Local local /usr/openwin/lib/X11/xdm/StartX

I have tried after commenting this line too. It still doesnt work!
