Lenovo W520/T520/T530 Boot Instructions for Fedora 17
Raw
gistfile1.txt
In order to get external displays working on Fedora 17+ with recent Lenovo laptops containing Optimus graphics you need to perform a few steps.
1. Enter bios, go to Config > Display
2. Change display to Discrete graphics (disable Optimus since Linux doesn't support it yet)
3. Set the default boot screen to Digital on Dock (if you have one)
4. Reboot
5. At grub2 loading screen, hit e to edit the boot params
6. Find the line that starts with `linux` and add ` nox2apic` to the end of it
7. Boot linux (ctrl-x maybe?)
8. Once booted and logged in, run `sudo nano /etc/default/grub` from the terminal
9. Add `nox2apic` to the end of the variable `GRUB_CMDLINE_LINUX`
10. Execute: `sudo grub2-mkconfig -o /boot/grub2/grub.cfg`
You should now be able to use external monitors with your laptop. Enjoy!

On Ubuntu this is necessary to simply boot the machine.

Change 10 to:

execute: sudo update-grub
