LxPlan doesn't work on Pop-os

[piermarco.lunghi]

As in the topic, I've installed lxplan on pop os, with java runtime v19. I can see the icon in the menu but it's not opening the software...please help!

[admin]

Open a terminal window and type the following command:

Code: Select all

java -jar /usr/share/claudeheintzdesign-lxseries/LXPlan.jar

This is the command used by the desktop launcher. Running it in the terminal should allow you to see if there are any error messages. There are a lot of possibilities. If either the java command or the -jar option are unavailable, then there is a problem with your version of Java. Otherwise, you should see what the specific problem with running LXPlan is.

Hi Admin!
What a fast support!! Thanks a lot! I think the problem is that:

Code: Select all

No X11 DISPLAY variable was set,


I think in pop os i'm running wayland, is this the problem?
I use LxPlan on my others mxlinux laptops and it run perfectly...

PS. I'm working as light designer for theater shows, in a linux-based way...not only open software but absolutely linux-based...so...i really need software like LxPlan, and if i can help you to improve it, i'll do what i can! (so let me know, eventually, if i can do something!)

PPS. the complete response is:

Code: Select all

Perhaps someone else knows something about Pop-os or wayland and can answer this. It sounds as though you may have unconventional hardware you are trying to run LXPlan on. If you google, you might find an answr like this one: https://stackoverflow.com/questions/662 ... es-it-mean

It may be that wayland is not compatible with Java:

Can you switch to X11?
