Radeon HD 8730M on HP 840 G1

Question

Hi, I'm trying to use an HD 8730M with an Intel HD4000 on a HP 840 G1.
When I instal xf86-video-ati (Open Source drivers) :
If I do an
echo ON > /sys/kernel/debug/vgaswitcheroo/switch
the server won't start, here is the log

Answer 1

Easiest way to make it prefer IGP is to let Xorg handle it, or at least I had no need for any extra configuration. My guess would be that you have leftovers in your config files when you installed Catalyst first, though it's just a hunch. If that's not the case, wiki has all needed configs. Again, chip which has output attached to it should be recognized automatically and preffered over the other one.
Yes it needs to prefer IGP because in muxless systems video output (screen) is attached to  IGP, not discrete card. What PRIME does essentially is offloading graphics from discrete card to integrated card's buffer as IGP is the one who has actual output.
As for performance, I am not a heavy gamer, or at least most of the time  I do not use anything that really requires extra graphics power from discrete card (occasionally give Xonotic a spin, and that's about it).  Therefor I cannot compare performance having no really relevant data. But what I can compare are temperatures, which in case of free driver are substantially higher than those with Catalyst. I'd really love to be able to use free driver on a day to day basis, but I'd rather switch discrete card off than having to listen the fan behaving like turbine all the time.
(P.S. I made a typo in previous message, it's not HD4000, but HD4600, quite a big difference in performance, will fix now.)
