Public bug reported:
Both during and after installation (meaning while running the USB iso
and booting from HDD after) ubuntu will rapidly become unresponsive and
eventually hang when my 4k monitor is plugged in. I have 2 monitors, a
1920x1080, and a 4k. Everything works absolutely perfectly if I only use
the 1920 monitor (this is where I am working from right now) but the
moment the other monitor is plugged in I get problems.
When I cold boot into the system from the small 1920x1080 monitor and
then plug in the 4k monitor, the screen on my smaller monitor will
glitch before returning to normal a few seconds later, while the 4k
monitor never displays an image. The OS begins to bog down, the mouse
begins to lag and become less responsive. If I open the display manager
I can see that ubuntu has properly detected the 4k monitor and has the
correct default settings (resolution, refresh rate, etc.) but attempting
to make any changes will result in an immediate crash/hang upon pressing
the "apply" button.
If I cold boot ubuntu with only the 4k monitor plugged in, I see purple
splash screen and ubuntu logo screens (at the correct resolutions) but
the monitor output stops and I see only a black screen before the login
screen is reached.
If I cold boot with both monitors plugged in I see the splash screen and
logo, there is a brief moment where the small monitor glitches, and then
I see only the magenta backdrop of the login screen but there are no UI
elements, and This is only seen on the small monitor; the 4k monitor has
once again lost input and turned black.
