If everything seems to have installed without error, reboot one last time. You can see a copy of my nf for reference here. Now, as explained here, you’ll need to make the following modifications to /etc/bumblebee/nf: (Thanks again to liskin, the developer of screenclone). Next, you’ll need to install screenclone, which copies the VIRTUAL display to your external display. This indicates that everything has installed correctly up to this point. At this point, if you execute xrandr in terminal, you should see two displays listed, one of them will be named VIRTUAL. Now, patch and install the Intel Graphics Driver to allow it to support a virtual display.
Next, you’ll install some dependencies for later parts. This gives you the ability to switch the nvidia card on/off in Optimus Mode (make sure this is set in BIOS).
Instructionsįirst, go ahead and install Bumblebee. I’ve been able to successfully perform them multiple times on a clean install of 12.04 圆4 on my W520. Additionally, if you’re running Arch Linux, check out Gordin’s adaptation of this guide for Arch.įor guaranteed success, you should follow these instructions to the letter.
None of this would have been possible without his original guide, which can be found in the sources at the end of this page. If you’d like to learn more about how the graphics are wired and why these workarounds are necessary, check out Zachary Sunberg’s post here. This setup, combined with thinkdisp will get you:Ģ) Working 3D Acceleration on all displays (so compiz effects work)ģ) Power saving when mobile (Nvidia card off)Ĥ) Safe updating without killing the multimon setupĥ) The ability to use VT-x (which has to be disabled in BIOS in discrete-only mode due to a bug) Optimal Ubuntu Graphics Setup for Thinkpads Motivation These instructions are available here for archival purposes.
