IMHO, if you want stable use of notebook, choose some with ONE vga adapter, nvidia is better, and stay away from Optimus Technology to use with Linux.Hi, I am in the market for a new laptop and I am trying to learn more about the current graphics situation so as to not make a mistake with my purchase.1. I looked at the Ubuntu Community Documentation for hybrid graphics at https://help.ubuntu.com/community/HybridGraphics. It has given me the impression that even if I buy an Optimus Sandy Bridge laptop, I can use vga_switcheroo to use my nvidia card, and perhaps the problem is with real-time switching of cards without restarting X. Is this correct? Can I just configure things so that the nvidia card is always in use? I don't care if the Intel IGP also stays on and eats power. Or is it possible that I won't be able to use the nvidia card at all and will have to settle for the Intel IGP at all times? 2. Is there a list or a wiki page with a compatibility list and or machine specific gotchas with bumblebee / ironhide? 3. How is the graphics performance when using ironhide / bumblebee? How big is the hit because of VirtualGL etc.? 4. Is there a list of laptops with hardware muxes / switches or BIOS options to only use the discrete graphics card? 5. I am having a dilemma about value for money between similarly priced i7-2630QM and i7-740QM notebooks. Any opinions on whether it is a waste of money to buy Clarksfield i7-740QM at the same price as a Sandy Bridge i7-2630QM notebook, only because the former will have hassle-free graphics? Thanks a lot for all your responses, and for all the work you guys are doing to bring hybrid graphics to linux. it is a shame the manufacturers won't put out proper drivers. Regards, Sarang
Remember, IMHO. Good Luck in your choice. -- -- Zhu Sha Zang _______________________________________________ Mailing list: https://launchpad.net/~hybrid-graphics-linux Post to : [email protected] Unsubscribe : https://launchpad.net/~hybrid-graphics-linux More help : https://help.launchpad.net/ListHelp
