However, the clock rates of the NVS 4200M in the Dell Latitude 6420 is similar to the GT 520M. The NVS series is optimized for business applications and stability and may therefore perform a bit worse in games due to the special drivers and BIOS optimizations. The gaming performance may be a bit worse.

Forgive me if this is the wrong place, but I'm having some issues getting Ubuntu Desktop 10.10 64-bit working on my new Dell Latitude E6520. It has the NVIDIA NVS 4200m graphics card. I am able to get it booted and working, but it must be using a default driver, since all the graphics are very slow even with all settings on minimum. There is nothing listed in the 'Install Proprietary Drivers' list. From what I can find on the NVIDIA Website (it's not supported yet. Does anyone know if there are plans to support it or if there is a way I can get them working at a decent level without the proprietary drivers?

From the specs here the Dell Latitude E6520 is Optimus enabled. Crashday Download Pc Completo Restaurant. In that case unless you have a BIOS option to disable Optimus.--I don't think the Dell offers that,-- you won't be able to use the Nvidia card in Linux even if the card is 'supported'. We are seeing more and more these days as most new laptops with Nvidia are Optimus enabled. This means Nvidia has effectively stopped supporting Linux laptops even though the cards may be 'supported' by Nvidia drivers. But worse, even though you cannot use the Nvidia card that you paid for (stuck with the crappy Intel card), the nvidia card would still eat your battery and generate heat. Better return your computer if you still can. Otherwise the least undesirable outcome out of all horrible alternatives would probably be to turn off the Nvidia card (so that it becomes a paperweight instead of sucking system resources) Please add your voice here.

I don't expect Nvidia to support gpu switching for Linux, but it is ridiculous that Linux users wouldn't be able to use the Nvidia cards at all,-- the cards that they pay for, and Nvidia supports with Linux drivers. Maybe you would also want to write to Dell asking it to provide the BIOS switch to disable Optimus. Hi again, Well having got the graphics working great with the Nvidia card, sound was now an issue. Spent ages looking around and then followed instructions on After much messing about.to no avail I got sound at reboot and nothing else. Disabled Nvidia sound card in 'System >Preferences >Sound' Hardware tab and enabled built in internal sound and all burst into life, so graphics and sound just my 'reboot' to sort out now and then I will have a working version of a Dell Latitude E6520 with 10.10. Thanks all in this thread helping me configure my Dell Latitude E6520. I thought I'd contribute back by providing a concise description of my system and setup and how I arrived at a working system for this notebook.
