Please help, How install AMD driver on Neon?

hi.
neon is based on ubuntu 16.04
so it ships open sources amd driver as default and no need to install additional driver mostly.

what is your amd gpu model?
enter this command in terminal and put results here :
lspci
or
lshw

I have notebook ASUS K53 with AMD 6*** cart
Open source driver not work, I constantly blinks Screen, work only fglrx driver.
Kubuntu 16 not work too.

Dude, look this tutorial: https://help.ubuntu.com/community/RadeonDriver

Its not for Neon/Kubuntu 16.10

Yes I know, but KDE Neon comes from Kubuntu and this from Ubuntu. Usually what works in Ubuntu wheel here too

AFAIK, only open source driver stack can be used. No Catalyst/fglrx video driver is available at 16.04. You may check https://wiki.ubuntu.com/XenialXerus/ReleaseNotes for details.
