I got a Startech mini-DisplayPort to 3x-DisplayPort hub. It works, but it is very iffy; sometimes Gentoo recognizes all the monitors, but sometimes not, or sometimes it will not properly detect their resolutions. Worse of all, if I unplug it from my computer, the computer stops responding altogether and needs to be turned off and back on. Has anyone else seen something like this, or are there any ideas that might help?

The freezing and detection problems happen in both Gentoo and Linux Mint.

Ok, no details. This is on a Lenovo Thinkpad T450s with kernel 4.1.15-gentoo-r1.
