Ubuntu won't install from CD (Now with pretty pictures!) - Page 5

post #41 of 45
"SLI in Linux is apparently not very well implemented and may cause a lot of instability and general lack of performance."

what? nvidia-drivers = SLI plug and play, no problems, great performance. The nvidia drivers are the same code interfacing with the card as the windows ones, just a port. written by the same engineers. .... not sure where statements like that come from. perhaps you're using noveau, which at this point is not worth using. any driver version v250 and up is fine. i'm currently stuck on v270 due to a bug in v290 not waking up from suspend

Agree. I ran SLI 460's with 6 monitors just fine for over a year, until I dropped it for one card and 3 larger monitors that are about the same size as the 6 old ones.

Although, the 580's may have a bit of trouble being it's somewhat newer, but I still doubt it.

Really? I am reading pretty much the opposite all over Nvidia forums and Google searches. Even as recently as a week ago I am seeing people saying their system runs worse in SLI than with one card. New cards or old cards.

If I am wrong and it's just isolated events then I am pleased as punch because I'd like to run SLI this year in Linux. It's good to hear that you guys are having no issues.

it definitely works fine ... adding the second card allowed me to keep youtube fullscreen in the second monitor while fullscreen gaming on the primary one. prior to the second card they both would bog down and stutter. it was literally add the card, turn the computer back on, and nvidia-settings showed everything all set automatically, no issues. it was "windows like" smile.gifrolleyes.gif

sli + nvidia-drivers = good stuff for sure.
noveau = too buggy at this point. maybe one day that will change.
ati-drivers = too buggy at this point. maybe one day that will change

I am running 295.20 which is the latest version from Nvidia. I have no idea how to try reinstalling the driver as I've never run something as root before...

One of the last installation steps will offer to update your X configuration file. Either accept that offer, edit your X configuration file manually so that the NVIDIA X driver will be used, or run nvidia-xconfig
