Standard forum response after months of observation:
Event:
Company is mentioned in relation to some usually peripherally related issue.
Response:
10 pages of conspiracy theory which boils down to I wish I was a full time developer for company x, but since I am not I will show through flawed logic why x is doomed and y is the root of all evil.
My response:
Read and laugh.
Keep it up. Tin foil hats unite on phoronix!

Ubuntu Still Figuring Out How To Handle Hybrid Graphics

Muxless PowerXpress can't do OpenGL on the Radeon card unless there's a BIOS switch for Fixed Mode. Enduro fixed this so OpenGL just works.

By the way, AMD proprietary driver in linux and muxless that work today is more a driver bug than a function.
Most of AMD muxless hardware still dont work. And the ones that work are in grace of the notebook manufacturer not because of amd..

Under windows is not much different if u are using AMD.
Virtually all notebooks purchased before the windows 8 RELEASE and dont have windows 8 manufacturer released for windows 8 are having problems too.
HP is one example.
Every line DV and Envy have problems. some of them same with windows 8 drivers still dont work.

That's history as I remember it...
On my notebook PRIME/DMA-Buf works fine with a HD 7970M. Now the only problem is that the radeonsi driver itself doesn't get much love.

Ubuntu is great, everything they've done is awesome. No one else has done anything that isn't crap.
Oh, something sucks? Well, why didn't someone else fix it? You can't expect Canonical to do anything, can you?
Really, I'm starting to get tired of the fan boys on here. It's not just pro-Ubuntu either, the whole site is crawling with them, and Michael encourages them to drive up page hits and ad revenue.
/sigh....

Originally posted by Ericg View PostOf interesting note is the actual implementation. On Windows when the hybrid kicks in, things flicker or stutter for a half second whenever you change GPU's and then youre good until you change GPU's again. On OS X interestingly, no stuttering or flickering or even pausing. It was either Daniel or David that said they most likely did all of their hybrid stuff inside their GL layer.

There are many different groups putting work into hybrid graphics. Now it's Canonical's turn. If all goes to plan, Lankhorst's fencing work provide the necessary X infrastructure for tear-free Nvidia blob use of RandR 1.4 in Ubuntu 13.10.
Once fencing is out of the way, people will move onto multi-monitor situations and power management. Everything is babysteps.
