Ubuntu 20.04 freezes when I connect external monitor through USB-C

in flag

When I connect an external monitor through USB-C my system freezes completely and the fans start spinning full speed and I can't do anything. It was working before but now all of the sudden it has stopped working. I used to be able to connect 2 extra external monitors (through HDMI and USB-C)

P.S. When I connect the monitor and then turn on the computer then it hangs at the splash loading screen.

Here is my setup:

Laptop - Lenovo Legion 5 (1 HDMI port and 1 USB-C port)
Intel i5 10th gen
NVIDIA GeForce GTX 1650 (with NVIDIA proprietary driver installed)

What I have tried so far but did not help

apt update && apt upgrade

What's dmesg says ? (`/var/log/dmesg*`). Simpler way is to run `dmesg -wT > ~/file.log` before plugging in ; you'll get the last logs in `file.log` after reboot. Also, a more complete setup could be helpful (drivers, etc) > `$ inxi -SPARM -GCDN -v1 -xGCRS` with inxi package

I'm coming too late to edit my comment, you can also explore full journal logs with `sudo journalctl -b -1 -e` (-1 for previous boot, -2 for the one before, etc)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
