Hey, Ruslan, I have a dv6-3160us with the same graphic cards: 4250 and
5650. I've tried every Ubuntu version and Catalyst version and I
couldn't make the 5650 works on Linux with proprietary drivers. I use
Ubuntu 12.04 and Catalyst 12.04 and the 4250 works perfect (only that
card). It's the way I use this computer.
I had the same problem. I wasn't able to run X with proprietary drivers,
getting black screen and couldn't figure out what's the problem. But
the idea of using old Catalyst, because it requires old X, so I wasn't
able to use
other new software.
Once, I could boot on 5650 with open source drivers... but I need 3D
acceleration. CONCLUSION: 5650 with open source drivers was slower
than 4250 with proprietary drivers.
Did you try to use open source drivers and use DRI_PRIME
<https://wiki.archlinux.org/index.php/PRIME>? It works well for me.
Test with glxgears shows that 4250 gives me ~60fps and 5650 gives me
I'm going to do the VERY LAST test installing Ubuntu 13.10 and the
last version of Catalyst (13.12 and 14.3beta) and see. But I have no
hope at all.
With 4250 won't work with the new versions of Catalyst. You might be not
able to simply install new drivers. Catalyst might be unable to detect
because default open source drivers do not turn on discrete card, so
might say that it didn't find any supported hardware.
Do you have any other information about this fucking laptop and using
I'm suffering from this laptop for a few years now. The only good
solution that I
find is using Archlinux with the newest open source drivers.
Even Windows works quite bad with this stupid combination of graphics cards
(yeah, thanks HP). Because of stopped support of 4XXX cards, I'm not able to
make new catalyst work properly. My laptop is hell-hot with proprietary
On linux everything gets better and better. Every new kernel works better
than previous one(i think these hp laptops have some problems with bios
Also every open source driver gets better every new release.
It's the reason why I use arch, it provides the most recent soft, so my
life with this
laptop becomes easier.
Yeah, next time I will be choosing my laptop much more carefully=)
So I recommend to use the newest kernel with the newest open source ATI
Then, you should turn discrete card on by using vgaswitcheroo:
# echo ON > /sys/kernel/debug/vgaswitcheroo/switch
Then, logoff and logon to restart X(don't reboot!), and then do what is
told here <https://wiki.archlinux.org/index.php/PRIME>.
As a result, you will be able to run 2 cards simultaneously! So X will
use 4250 and
some performance-hungry, for example, game will use 5650.
I hope it will work for you. If won't, you can ask me or ask guys on the
channel, they helped me a lot.

Did anyone try to use similar thing for OpenCL?
I've tried to use both open driver and catalyst.
With open driver, I've tried to use opencl-mesa, but any of test
programs didn't work. They all end up with clGetPlatformIDs() -1001,
although there was mesa.icd at /etc/OpenCL/vendors.
As for catalyst, new versions do not support my 4XXX card, but do
support 5XXX one. With old drivers I didn't succeed in making X
work. But, maybe I should take a better look at xorg configuration
The only implementation of OpenCL that do work is Intel SDK. It does
programs using CPU, but many programs doesn't work, saying that
there are no
If someone tried and succeeded/failed in making OpenCL work on
