[KOSKERS]

I have installed the bumblebee and nvidia331.20 normally. i can switch between two card normally.
But, when i change to nvidia card in order to play dota2, it is slower than intel card.. WTF.

I can confirm this issue. Running Kubuntu 14.04 and performence in steam game sis owfull. All worked fine on 13.10 and the problem showed up after upgrade.

I'd suggest it's the nvidia driver, as I'm finding the performance of it isn't as good as the previous one. I find I'm getting some tearing on graphics heavy forum pages.

[frekja]

I have a very similar problem with ubuntu 13.10, bumblebee, and nvidia-331 drivers - games run about 10x slower using primusrun and optirun compared to my built-in intel graphics. Nvidia-325 performance was fine.

I can't find any ubuntu-specific advice, but it looks like the problem affects OpenSuse and Arch as well: see http://forums.opensuse.org/english/g...12-kernel.html and http://forum.manjaro.org/index.php?topic=8346.0 . These both seem related but I'm not aware of the equivalent packages for ubuntu. I've already tried purging and reinstalling nvidia-331 using the xorg-edgers PPA, but without success.

[UPDATE] ppa-purging bumblebee and xorg-edgers, and manually removing all nvidia drivers, then rebooting and reinstalling fixed this problem for me.

I have the same problem. Since I have installed 14.04 the video performance is so bad. I had no problems with the nvidia drivers on ubuntu 13.10.

i5 8GB GeForce 310M
Driver: Nvidia binary driver version 331.38 from nvidia-331

Edit: My computer doesn't have dual GPUs, sorry if this is the wrong place to post

@DanyalDenyo, I guess you miseed the blue banner at the top of the page, this sub-forum is for the discussion and troubleshooting of Utopic Unicorn, discussions of released versions should take place in the other support sub-forums. Thread closed.
