Unable to start xclock in Linux for my oracle reports- for bar code printing

anumoses · 04-15-2011, 11:37 AM

$DISPLAY=localhost:0.0
$ export DISPLAY
$ xclock

It hangs.
When I do xhost + also it hangs.

Without the xclock I am not able to run oracle reports in production for bar code printing as I am not able to start a standalone reports server. Help needed to start xclock and where to look for any help

It's not hung, its running in foreground. If you want your shell prompt back you need to do:

xclock &

Well, put "&" after it , too! "&" means "run in background".

And remember, the terminal is not "hung", it's just that keyboard input now goes to the running program until it exits, and then the shell returns.

To pause a foreground process, use Ctrl+Z. To start it again in the background, run "bg". To start it again in the foregraound, run "fg".

You do not need xhost + unless authentication is being done wrong on your system.
If you own the display, then programs you launch can use it.
