Hah! At least you got it to work. OTOH on my old GT725 w/4850/Ubuntu x64 the installer and everything usually worked unless the install script was borked in some fashion, but the driver itself was of pretty poor quality at best. Video tearing up the wazoo. Bugs, bugs, bugs with more bugs(some nasty ones like hardlocking the GPU in certain rendering scenarios, which I narrowed down to either a hw design defect or a driver defect as it would do it cold start or running hot) added with every new crapalyst release.

Now moving on to the present in a fit on insanity(must've been as you'll see) I decided to try out current AMD/ATI hw by building an FX-9590(thx microcenter cost 8350), ASROCK Extreme9(not many choices for that insanely overclocked/overvolted CPU) coupled with an R9 280X(wasn't going to spring for a 290 given my past ATI experiences), win 8.1 pro x64(16GB) so builds all fine, old pre-mantle catalyst drivers install fine and imagine my surprise to find that they figured out how to unload the old vid driver AND then LOAD the new one restoring by display(there was MUCH rejoicing, although IIRC nVidia's always managed this feat, yes after the GT725 I pretty well swore off ATI). Now feeling all giddy about how catalyst almost seems to kinda sorta be decentish now I again insanely decided to try out the latest window beta(alpha or gamma would be more accurate IMNHO). Use the ATI driver removal tool to scrub the old driver(yes I know guru3d DDU, but wait), OK reboot try to install 14.4 "beta" ok driver loads, and then promptly craps out trying to install their feeble attempt at GF experience or the control panel.
Start over, scrub, reboot, and again driver installs, control panel appears to install then craps out again. OK ATI xp not there, no big loss, try control panel, oops sorry crash bang.
Start over, vid driver again installs, control panel craps out, but ATI xp installs.
Gave up at that point for the moment, next try will be via Guru3D DDU scrubbing, so I stopped there not even wanting what I FULLY expected to be a worse experience trying to do the same under linux and shoved the box back into it's corner again.
(Main desktop is a 3930k/780 Ti which just works(even the nv "beta"s) win 7 pro x64/Ubuntu 13.10 x64. As mentioned above I swore off ATI after the miserable GT725 experiences, and sadly am still glad of doing so, although the fx-9590 is pretty much a dog or maybe it's more the combo of AMD CPU and ATI GPU w/crappy drivers making everything feel so sluggish. Notebooks are 780m and 765m as well, as I'll re-iterate I swore off ATI and there was no way that I was going to experiment with them in a nb again where it's difficult at best to swap a GPU and might not even be possible if it's soldered(e.g. 765m, 780m's an MXM card).)
All of that said it sounds like surprisingly that the linux catalyst drivers are in better shape than their windows drivers other than overall perf...
