I'm surprised they let you dual boot a managed machine, since the Linux installation likely isn't running any of their management software. At my work, we're not allowed to dual-boot, but at least they support Fedora. (their production servers use CentOS and Fedora is close enough that they can reuse a lot of management infrastructure like Chef recipes across both)

See if there's a setting in the BIOS to always use the Nvidia graphics. It'll use more power but should be more reliable.

Hybrid graphics is notoriously buggy on Linux, especially reverse PRIME. Reverse PRIME is used when the video output port on the laptop (DisplayPort, HDMI, whatever) is physically wired to the discrete GPU, but the system is the integrated GPU. There's a well-known bug with reverse PRIME where the screen only updates at 1fps when only using an external monitor (laptop screen is disabled).
