You may refer to https://wiki.archlinux.org/index.php/ATI_Catalyst,
Catalyst does not support the newest Xorg servers. They do not update
their drivers much(or someone can say Xorg is changing their driver
interface too much) for what ever reason it won't work with newer
Xorgs. And newer Ubuntu's use newer Xorgs that might be your problem
but I am not exactly sure if you have time and knowledge I recon you
try arch on a separate partition. It gives you more freedom to
configure which version of what you's be using.

I bought a HP laptop a year and half ago. ATI hybrid with MUX and
12 months hw part-only warranty. No official linux support.
Month 0-6 - lots of unsuccessful fiddling and performance with
ATI driver was the same as with Intel opensource. Not worth the
money and effort.
Month 7 - finally ATI driver works as supposed. I was able to
switch with a logoff/logon and it worked at least 3 times faster
then Intel in some tests I did. Unfortunately, gnome3-shell did
not work with ATI driver. I dropped ATI driver and started to
switch off the card during boot.
Month 9 - later ATI driver versions supposedly fixed the problem
with Gnome3, but it started telling me the card is not supported.
Some month or so after, I was informed by ATI staff that MUX are
not supported any more and never will be.
This happened even before the basic hw part only warranty was out.
HP does not care - it was never officially supported.
ATI does not care - it was never officially supported.
I agree with Linus' reaction and extend it warmly and happily
towards HP and ATI, and of course Microsoft where the whole thing
has it's roots.
Hey, Vangel, I have a similar situation.
One year ago, I bought Acer with notebook with Optimus. Then, I
realized that it wasn't for Linux... I changed it for a Pavillion
dv6 3160us, with 4250 and 5650 ATI cards... thinking PowerXpress
DID work on Linux... I couldn't ever used the discrete card with
Catalyst, nor OpenSource Drivers.
The best configuration I was using was: Ubuntu 11.04, Catalyst
11.6. There were some artifacts moving some windows, viewing video
with hardware acceleration and using a 3D engine (Blender)... but
the computer worked for my needs (look at it:
http://vimeo.com/35154176, at minute 1:00 the digital puppet starts).
Since I get the HP, I tested Catalyst 11.7, 11.8, 11.8, 11.10...
Ubuntu 10.04, 10.11, 11.10... Mint... and in any of these software
configs, couldn't use Blender (edit mode) because of visual
errors. In Blender, the display had a ONE-EVENT-DELAY. This mean
that, if I pressed a key, it display the change in the screen not
at the moment, but the next time I press another key (or mouse
click). All the events has that delay... yes, I know, it's very
strange.
I test vgaswitcheroo in Ubuntu 11.04... nothing. There's no way to
use change to the discrete. And the open source drivers are really
slower than the proprietarie's.
Then, Ubuntu 12.04 arrived... and the last version of Catalyst.
The discrete card still does not work, but: The hardware video
acceleration is OK. Blender works OK. Only few artifacts on moving
Blender windows... but now... I HAVE AUDIO PROBLEMS! I'm using
Jack and have XRUNS (buffer under-or-overrun) that I didn't have
before.
(Vgaswitcheroo doesn't work in Ubuntu 12.04)
I repeat... discrete card still does not work. I've used the 4250
integrated card.... but spend so much money to have the 5650.
Fuck you, ATI. Fuck you, HP.
