I know there is a lot of material regarding these problems, but much of it seems outdated and nothing seems to be working for my situation:
- ThinkPad W520 (Intel 3000 and Nvidia 1000M chipset)
- OS: Ubuntu 12.04.3.
- BIOS graphics card setting:
- BIOS OS Optimus auto-detection:
I used the Bumblebee wiki below to install and setup Bumblebee: https://wiki.ubuntu.com/Bumblebee#Installation
After setting my BusID for the graphics card to "PCI:01:00.0" (see config files below), I am able to run
optirun firefox and the virtualgl tests like
optirun glxspheres64 and
glxspheres64. So, I believe all is well with the Bumblebee installation, except I cannot connect to my external monitor (via VGA). Any ideas on how to do this? The W520 has the VGA (and DisplayPort) hardwired to the Nvidia card, as described by Zachary Sunberg:
So, I believe this makes things a bit tricky when trying to connect the VGA to an external monitor. I believe that I have to use a server/screen clone, described in my attempts documented below:
I tried the following post to configure the external monitors,
But rebooting after step 7, causes the OS to completely crash (black screen after the bootloader that says "Could not write bytes: broken pipe"). I believe this is due to the xorg server disrupting my system somehow.
I tried a similar approach in the following tutorial, but I had the same crash as in (1) during the reboot after installing xorg-dev:
As of now, I am wondering where to go from here. I have a couple leads below, any ideas on what the problem is, or what I can do? Is there a better suggestion? http://zachstechnotes.blogspot.com/2012/04/post-title.html
Also, here are some of my files (let me know if there is a better configuration - the only change I made was uncommenting the "BusID PCI:01:00.0" in the
