Good to know. I'm currently in 15.04 on ...Oooh. Good to know. I'm currently in 15.04 on a W520, with primus installed and (shockingly) working. (And using some absurd new-version driver.)<br /><br />There are a couple of tricks here.<br /><br />I used: http://rajat-osgyan.blogspot.com.au/2015/03/how-to-install-bumblebee-on-ubuntu.html (beware his typos though. Commands should be inspected, not simply copy-pastaed.)<br /><br />The driver name will be annoying.<br /><br />The bit that was tedious for me was getting the bumblebee.conf set up right:<br /><br />KernelDriver=nvidia-346<br />PMMethod=auto<br /># colon-separated path to the nvidia libraries<br />LibraryPath=/usr/lib/nvidia-346:/usr/lib32/nvidia-346<br /># comma-separated path of the directory containing nvidia_drv.so and the<br /># default Xorg modules path<br />XorgModulePath=/usr/lib/nvidia-346/xorg,/usr/lib/xorg/modules<br /><br /><br />is what I ended up with in the annoying section.<br /><br /><br />And the final thing that made it click (and be useful) is to ignore primusrun, but used the prime indicator http://www.webupd8.org/2014/01/prime-indicator-lets-you-quickly-switch.html that literally allows me to swap intel/nvidia states.<br /><br />Anyways, thanks for the heads up. Which nvidia drivers are you using? <br />Brian Ballsun-Stantonhttps://www.blogger.com/profile/09506402044183009177noreply@blogger.com
