I have a Mitac P100 touchscreen PC running Ubuntu (I have tired 18.04 and 20.04) and the touchscreen works fine for everything except IA client programs. I have tried it with the Vision Client and Perspective Workstation. None of the buttons will respond to presses. If I hook a mouse up everything works like a charm. Has anyone run into this issue before? Any solutions out there? ---

What event are you trying to use on the buttons (actionPerformed, mousePressed, mouseReleased, mouseClicked, etc…)? Touchscreen drivers generally just turn presses into mouse events of some kind. ---

I’m having issues within the program itself not my projects. For example I can’t click on the “Add Application(s)” button or if I have already added an application I can’t select it and click “Open Application”. If I plug a mouse in I can launch a project and within a project I seem to be able to click on things just fine. I made a quick test project and put a multiStateButton on the page and I can click through all three states no problem. Also all the buttons on the app bar respond to presses. EDIT: Quick additional test I just did. I added a button with an onActionPerformed refresh event and it works no issues. I changed it to an on-click event and it also worked ---

Support for the on screen keyboard was added recently (the nightly from 2/24/2021) which also included a fix for this issue. you could use the nightly version if you need this functionality immediately, otherwise you could add `-Djdk.gtk.version=2` to the `perspectiveworkstation.sh` script in the app directory to get touches to work in Workstation on the management side. If you launch a perspective session you may hit some inconsistencies without the changes that were brought in for that nightly. ---

Ok Awesome. I will spin up the nightly on my dev server and see if that fixes my issue
