I have a new Thinkpad X1 Extreme which includes NVidia Optimus. For my Linux work, I don't want to use the NVidia card at all, and only use the Intel integrated graphics.
When I try to boot the standard Ubuntu MATE distribution (either my disk from my previous machine, or a fresh USB stick), it locks up when the graphical environment starts.
Things I have tried:
nouveau.modeset=0on my Grub command line.
- Adding a file to my
prime-select intelto (theoretically?) select the Intel card.
- Installing the NVidia closed-source drivers while keeping Secure Boot locked, so they can't be loaded.
I've tried using a System76 Pop OS USB stick. The NVidia version works, but the ATI/Intel version does not. This is even when Secure Boot is enabled, so the NVidia drivers should never have a chance to load.
In short: what magic can I do to match whatever System76 did to get integrated graphics only to work?
System76's ISO creation script is on their GitHub page so it may have clues.
