Sometimes "troubleshooting" instructions say
to include nomodeset on the kernel
cmdline. You do not want to do that if you want an acceptable FOSS Xorg driver
to function. Nomodeset can work with the proprietary NVidia driver, but it
blocks use of modeset and nouveau Xorg drivers.
The "Troubleshooting" menu item lets you select "basic graphics
mode".
After a day of futzing, this was the only way to get to the
installation screen. Using the regular install selection yielded disk
accesses (when I was trying with a DVD) and a black screen.
I couldn't find whatever doc you read that in, but
"use a basic video driver"
My assumption was that this would get me through the installation and
not set it forever and ever.
happen. To find out which driver is being used,
inspect /var/log/Xorg.0.log for
a large number of sequential lines beginning around two screens down from the
top of the file. Look for:
fbdev(0)
vesa(0)
modeset(0)
nouveau(0)
I've never been good at deciphering Xorg.0.log files, but ...
[ 1638.443] (==) Matched nouveau as autoconfigured driver 0
[ 1638.443] (==) Matched modesetting as autoconfigured driver 1
[ 1638.443] (==) Matched fbdev as autoconfigured driver 2
[ 1638.443] (==) Matched vesa as autoconfigured driver 3
Who do I tell which one is being used and then how do I manipulate it?
Share Xorg.0.log via pastebin if the above isn't
enough help.
Oh, good idea. Hang on ...
OK, see if this works: https://pastebin.com/bhnUCYSD
