Comment 6 for bug 1730211

This is still an issue on Ubuntu 18.04 using Xorg.

Interestingly, capital letters now work on the login GDM screen.

But on the desktop, it does't work.
Touching the virtual shift key still produces lower case letters.

Also, when I select the symbols key to bring up the symbols keyboard layout, not all the keys work.
The keys below the top row number of number keys actually produce numbers instead of symbols.
Some of the virtual symbols keys do nothing.
