Can I install Ubuntu on a PC that has a touch screen?

Question

Specifically the HP ENVY TouchSmart All-in-One 20-d003la - All in one - 1 x Core i3 3220 / 3.3 GHz.

I mean, if the touch screen will recognize the 5 fingers?

Solution

Try booting LiveUSB on it. If it doesn't work, check if the touchscreen is listed there:

You can also check info at https://wiki.ubuntu.com/Multitouch , especially https://wiki.ubuntu.com/Multitouch/Testing that contains descriptions of tools to check multitouch devices. You can install them in the live session in the same way as on an installed system.
