Ubuntu 20.04 LTS - 软件更新后 prime-select 不起作用

Prime-select 告诉我我使用的是 nvidia，但事实并非如此

1-2 个月前它运行得很好，但软件更新后，我不能再使用外接显示器了（Acer Nitro 5 - HDMI 仅连接到 nvidia gtx1060）

安装不同的驱动程序 440/435/390 不会改变任何东西。以前的内核也只能在英特尔上运行。尝试重新启动

szymon@szymon-nitro:~$ glxinfo|egrep "OpenGL vendor|OpenGL renderer"
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) UHD Graphics 630 (CFL GT2)
szymon@szymon-nitro:~$ prime-select query
nvidia


... some info below ...
