I try to start the Xserver manually after disabling the LXDM desktop.
After start up the ps ax | grep X shows me:
And after stopping the lxdm
When i try to start my GTK applikation, it fails because of “cannot open display: 0.0”
Then i tried to start the XServer like this, without any success. The login screen appears in the terminal.
Does anyone have an idea how to correctly start the display driver for a customer application?
Many thanks for hints and helping me with this issue.
