Looked at the bios updates:
Fantastic news. Where did you look? You mean Lenovo’s bios updates? I’ll look into this and make this forum know.
I did the BIOS update (29 Jan 2021) but the issue remains even though slightly different. The screen is not black now but it get stuck on the LEGION + Ubuntu loading screen.
If I connect a 2nd screen (HDMI) I can see the login screen on the 2nd screen whilst builtin screen is black (but with backlight on).
I tried an apt-get dist-upgrade, I disabled Secure Boot in BIOS. No luck.
I am able to log into the machine via ssh.
What shall I do from here??
ps: I uninstalled nvidia drivers for now and the builtin screen came back. Obviously not what I want but I think it’s important info
Please update SBIOS to latest release and then try with latest nvidia driver.
Will await for test results.
你好，我也遇到了你这个问题，可以方便加个联系方式私聊一下，我的是华硕天选2的，cpu是R7-5800h,RTX3070的显卡，安装了nVidia-460的驱动或者其他版本的驱动重启就是黑屏的想象，试了好多办法都不行
but… that’s what I did in my previous post. I updated to the latest available BIOS (Lenovo Legion 7i) and installed the latest available Nvidia drivers. My previous post reports the result: login screen shows up only when a second (HDMI) screen is connected.; if only the built-in screen is present, it boots but it gets stuck on “LEGION / Ubuntu” loading screen
@spacewarper I’m having the exact same problem you have.(Lenovo Legion 7i / nvidia-driver-460 → Black screen appears on built-in monitor. But second monitor connected with HDMI works fine) Have you solved the problem?
I solved the problem. I hope it helps.
Setting “Dynamic Graphics” on bios menu
Reboot → enter BIOS by pressing F2 → Select “Dynamic Graphics” → Exit
Install nvidia-driver using “ubuntu-drivers autoinstall”
sudo ubuntu-drivers autoinstall
sudo apt-get upgrade
sudo apt-get update
sudo reboot
