Hello!
Well, this one has me stumped! I have a new touch screen (https://www.amazon.co.uk/gp/product/B07ZD53NVQ) connected to an udoo-x86 single board computer. I've just installed Ubuntu MATE 20.04 and it looks and works fantastic, except a little problem that I can't seem to sort.
I can select menu items on the panel with the touchscreen. Both global menu and app indicator menus pop up, but if I select a menu item it highlights it for an instant but won't select it.
Everything else works exactly as expected - Brisk menu works fine, both Mutiny and Familiar versions. Menus within apps like Firefox and Libre Office work perfectly with the touch screen and the 'onboard' keyboard works great too. It is just panel menu items, and only with the touchscreen - I can connect a mouse and it all works as it should.
I'm stuck as I'm not sure if this is a kernel or software problem. I tried the screen on another single board computer I have running ubuntu Budgie 19.10 and could select everything fine.
have I missed something obvious?!? Thanks loads for any help!
