Re: [Hybrid-graphics-linux] Nvidia responds to Linus
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. On Thu, Jun 21, 2012 at 1:44 AM, Mario Mey mario...@gmail.com wrote: El 19/06/12 18:43, Vangel V.

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 discrette 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 discrette. And the open source drivers are really slower than the proprietarie's. Then, Ubuntu 12.04 arrived... and the last version of Catalyst. The discrette 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... Discrette 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. ___ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : hybrid-graphics-linux@lists.launchpad.net Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp ___ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : hybrid-graphics-linux@lists.launchpad.net Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp
Re: [Hybrid-graphics-linux] Nvidia responds to Linus
in fairness that is a sound response - after all its a business BTW did I say thanks for the hardware Bumblebee Devs put in! I know precisious little about how things work but would love to get involved somehow. I use Bumblebee for running Graphics apps such as Blender and because later this year I start learning C++ openGL. I have started the C++ bit already so I know very basic stuff. Is there anyway in which I can get involved?

Re: [Hybrid-graphics-linux] Nvidia responds to Linus
It's a fair response - except that it completely avoids the issue that 90% of laptops shipped with NVidia chips ( estimated statistic, don't quote me ) are using an Optimus configuration, rendering the fantastic NVidia driver completely moot. I realize that X is in no state to support switchable graphics, but at least a solution to provide using either one chip or the other would be MORE than sufficient. :) Cheers, David On Tue, Jun 19, 2012 at 9:54 AM, jason peel jason.pe...@gmail.com wrote: in fairness that is a sound response - after all its a business BTW did I say thanks for the hardware Bumblebee Devs put in!

Re: [Hybrid-graphics-linux] Nvidia responds to Linus
IMHO, this just avoids the bad that nVidia has done and highlights the good they've done, anyone can do business with Linux no said thats bad, even though developers hate binary blobs most users love the performance gains from them instead of the pains of maintainability. The problem here is that nVidia is still not even thinking of bundling the binaries for switching! They've let the community figure it all out by reverse engineering and what not, and might even sue for some ludicrous reason like these people have unveiled/published some super technology that is patented by nVidia , Just a bundle of official support won't hurt anyone. And will make a lot people not waste their time configuring graphics cards! Xorg might not support seamless card switching: but who asked for seamless? People just need a way to switch the cards on Linux *some how* without getting in to details. nVidia is now riding the Xorg bandwagon for optimus, soon they'll be presented with Wayland, if I'm not mistaken they've announced that they are not planning for Wayland. - Madura A.
