Hi. I was trying AMD forums, Phoronix forum, Ubuntu launchpad without 1 single response, so I guess I will try here too...
So, I'm using ATI 7850, installed Ubuntu Gnome 14.04. At first I tried fglrx from "Additional drivers", which didn't work (same as the new one, read on). So I reverted back to Xorg drivers, which are awesome. Now that the new version of Catalyst is available, the 14.4 RC1, I convinced myself to give it a try again. So I downloaded the driver from the AMD website, installed, rebooted, and it didn't work again, just like the former fglrx.
So my issues are:
- The top 1/3 of the screen was tearing when moving windows, scrolling, etc. Tried all the settings possible with Tear Free and VSYNC. Currently I have two options: Either I use Tear-free, which removes my top screen tearing BUT the whole desktop is totally laggy and slow. Like moving windows around, resizing, showing Gnome Activities, etc...Or when I disable Tear Free, everything is fast and snappy, just like with the Xorg drivers, but the top of the screen is tearing like hell. This is my personal biggest issue, because the desktop experience is absolutely terrible with fglrx. With open source radeon drivers the desktop is extremely fast and snappy...with fglrx just terrible.
- Docky has a weird glitch when set to 3D mode, like it extends the dock panel more as it should, without textures applied. I can't provide screenshots since I'm back to open source drivers and I'm tired of constantly reinstalling them.
So there are my problems. I really would like to use Catalyst drivers, as I play some games and I noticed the performance is much better with Catalyst (tried Portal2, Dota2) and also with Catalyst, my GPU fan speed adjusts dynamically with load. With RadeonSI drivers, the GPU reclocks itself, but fan speeds are constant, which is really annoying when the card is idle.
Any help appreciated!
