This worked for me installing latest AMD drivers downloaded from here -
http://support.amd.com/en-us/download/d ... =Linux+x86
I'm running 17.1 "Mate" I had enabled the included fglrx by mistake before trying to install the latest downloaded drivers. I had to remove them using Synaptic manager.
Uninstall current fglrx drivers using Synaptic -
Use the search box with "fglrx" as the search term.
Mark for uninstall ONLY the already loaded drivers marked with the green square leftmost.
Proceed by clicking the "apply" button.
Reboot the computer.
Download the new drivers using the above link ^ (If you haven't already)
Open the downloads folder and right click the downloaded package and select "extract"
Double click on the "fglrx 15.501.1003 folder icon that appears after the extract.
The AMD driver installer will open, select the 2nd option for installing the drivers, not the custom... I don't remember what it was called.
The app should install the drivers for you.
Reboot the computer.
In the driver manager you should now see "manually installed drivers" checked.
Watch your stuff, these work WAY better than the 13.x drivers that come in the 17.1 package. I have a R7 200 series video card. You can check for your card in the info area on the download link.
If you use VLC make sure you select deinterlace (blend) if your hardware is fast enough. You can toggle using the keyboad key "d" while watching a video to see the effect.
Let me know if I got the procedure right, I'll edit it if necessary...
Cheers
