Hello yes, printenv shows
DISPLAY=:0.0 and tomp@ThaiTowerD10:~$ echo $DISPLAY :0.0 UPDATE: I replaced my pyvcp-widgets with one from master and get same err so I think the err is misleading and caused by my test.hal or .xml thanks TomP On 11/19/23 20:37, Chad Woitas via Emc-developers wrote:
If you run "printenv" do you have a display in there ? Or "echo $DISPLAY".
