Hi All,
I've installed F31 + Nvidia driver from rpmfusion on a Thnkpad-P1.
This works reasonably well. However I'm unable to use an external
monitor with this setup.
Checking if anyone has a similar setup - and succeeded in using an
external monitor.
Note: the LCD is 3840x2160, external monitor is 1920x1200 [connected
via hdmi port]
I've tried various things - but no success.
- prevent nouveau, nvidia drivers from getting loaded i.e use only
i915. xrandr sees only 1 monitor. Likely the following reason

>>
The P1 has all external outputs wired to nVidia so
unfortunately there's no way to get Intel to drive external monitors.
<<<
- prevent nvidia - and use nouveau - but then the external display is
not really visible except for the mouse arrow (enlarged). [and
nouveau is unstable on this hardware - crashes pretty quickly]
- use nvidia driver. xrandr lists only one monitor. nvidia-settings
shows the second monitor in one of its tabs though.
However - when I boot with PoP_OS 19.04 NVIDIA image - the external
display works from it. Its using 430.34 driver. And nvidia-settings
shows quiet a few more tabs related to X11 settings - and this
external display. And "Display Settings" has more options regarding
HiDPI.
But I'd like to get this working from Fedora - if possible.
Thanks,
Satish
