It boots to a blank screen (no monitor signal) unless I use "nomodeset" when booting, in which case it says it's running without video hardware acceleration. Driver Manager says "Your computer does not need any additional drivers."
I switched to the latest kernel 5.8.0-55-generic, did all updates in Update Manager, tried other versions of LM (including 20.2 beta), and tried two different monitors (DisplayPort), but nothing helped.
inxi -Fxxxrz suggests that the graphics driver is not present. But the only answer I found online was that it should work because the Intel graphics driver should already be in the latest kernel. (By the way, I also didn't have an ethernet connection until I manually installed the e1000e driver.)
How can I fix this so I can run LM without "nomodeset"?
