I am getting “X startup failed” before the installer screen on my Lenovo ThinkBook 15 IIL. I have tried a couple of alternate startup lines to no avail.
The installer script suggests “try again with the inst.text bootoption to start text installation”. I tried appending --inst.text to the startup line, but got the same error as before.
Someone else had graphics driver issues and replaced vesa with intel (and removed
nomodeset). My machine has Intel graphics, so I tried that, but got the same error as before.
