Some more information: - If I switch my primary display adapter in BIOS to the onboard GPU, I can get all three monitors and two cards working, but the framerate on the monitors attached to the PEG GPU is so low that it's almost unusable. - If I set the PEG GPU as primary display adapter, all three monitors work until it gets to the lightdm greeter where only the monitor attached to the integrated gpu works.

However, both of them display information during boot. Let me know how I can narrow down the bug report.
