Is this still a problem?

[isi (isiupisi)]

It worked for a time,but now the touch is only recognised on the upper-left half of screen, using Unity or KDE on Trusty and Unity on a Utopic's live-DVD;
so: yes there is still a problem ;-)

[Andrea Azzarone (azzar1)]

@isi, does it happen after few clicks or all the time? Did you change the scaling settings in Control Center -> Display panel?

[isi (isiupisi)]

@Andrea, after a test with windows, it seems that it's the screen itself that doesn't work well, so the bug can be claused...
thx for help anyway
