I've downloaded the 14.4 driver for Linux on my fresh installed Ubuntu 14.04, installed the Catalyst with GUI and rebooted.

I'm using ATI 7850 2GB.

The problems were:

  • the top 1/3 of the screen was tearing when moving windows, scrolling, etc. Tried all the settings possible with Tear Free and VSYNC, no solution.
  • no hardware acceleration for videos in any player. works totally fine with open source radeonsi drivers + VDPAU in SMplayer, but not with fglrx.
  • edited::: Docky has a weird glitch when set to 3D mode.


Any solution for these issues available/how to debug?


edit: somehow, after reinstalling the driver, the game performance is okay now. Also, when I enable tear-free desktop, the top third of it doesnt tear anymore...but all windows actions have slight lag, like moving the window start moving 100ms after I really move the window. Didn't happen with open source drivers...So either I have totally laggy desktop without tearing, or my top part of monitor is tearing like hell, but everything is fast and snappy.

Michael on Phoronix is testing this driver and hasn't reported issues like this, even though he used multiple cards. You may want to ask around there, maybe on some Ubuntu forums, maybe on Steam for linux forums, as you will hardly find linux users here, even the windows sections are mostly deserted.
