Ubuntu 20.04 hangs frequently

Just installed Ubuntu 20.04 on a new computer (Ryzen 7 5800H, 16GB, RTX 3050 Ti) alongside Windows 10 and it's hanging very frequently after startup - this started from the very beginning. It's usually only a few minutes and doesn't correlate with anything in particular as far as I can tell. After it hangs, very few things work, although SysRq codes appear to still work. It's definitely not a memory issue (it's only using a couple GB when it hangs), and I usually haven't had time to open anything except a terminal by the time it hangs - nothing resource intensive. I looked briefly at dmesg and syslog and there didn't appear to be anything out of the ordinary. I'm suspicious of the GPU drivers, since some other similar questions had problems with that, but I'm not sure what fixing that would entail.

Được rồi, hóa ra đó là sự cố trình điều khiển đồ họa (theo như tôi có thể nói). vừa chạy sudo ubuntu-drivers tự động cài đặt xuất hiện để khắc phục vấn đề.
