I wanted to install Ubuntu on my tablet pc as main operating system but it was really hard to make it working with touch screen.
The system reacts on touch and mouse click differently and it produces bugs which make it hard to use at all.
I tried all major desktops - Unity, Gnome, LXDE, KDE etc, and only Unity works relatively good with touch screen. But Unity also has touch screen bugs - for example, it is impossible to use Firefox or Chrome. When I tap on menu button in Firefox (it is rightmost button, contains zoom, print, history, full screen command etc) it does nothing. When I tap on any combobox in Firefox, it blinks for a moment and disappears - so it is impossible to use comboboxes. Tabs in Chrome also dont work - if I tap on tab Chrome does not switch to the tab. Note that if I use mouse everything works. If I switch to other desktop, for example, KDE, Chrome and Firefox start working with taps, but KDE has more serious bug - it stops reacting on taps after some time passed, I cannot say the reason. Also on-screen keyboard works very bad in KDE - it does not show up automatically, sometimes it even does not show up on login screen. It is not a problem if you have keyboard, but if you have only touch screen....
So I reverted back to Windows on the tabled and continue to use Ubuntu on my desktop as there are no such problems.
I would be very glad if someone could help me with taps on Unity.
Thanks, Oleg.
