Fedora 30 Video Driver(s)
by andymck from LinuxQuestions.org on (#4T0PJ)
A little background first: a week or two ago I did a 'dnf upgrade' which, among other things, put me on kernel 5.3.xx (5.3.4, I think it was, but I'm not sure) and rebooted. As soon as it went past the grub screen, the monitor went blank, the amber 'No Signal' light went on, and it stayed that way. I rebooted, same thing. The only way I could come up functional was to select the kernel 5.2.xx option in my grub list. Not coming up with any better options, I did a backup of my /home directory and installed a new system.
Guess what? SAME THING -- except that now my version 5.2.xx kernel was gone, so I could do nothing!
After a little floundering around, I happened on doing an installation in rescue mode, which apparently didn't sense my video hardware and so installed some lesser-capability drivers, but did (and do) work correctly. I restored my /home directory, re-created my various users, re-installed the packages that I use but weren't part of the installation, etc., etc., etc.
So, now I'm back to normal, EXCEPT that, every time I boot up and/or log in, I get a pop-up notification that says (quote):
----------------------------------
Check your video drivers
Your system is currently running without video hardware acceleration.
You may experience poor performance and high CPU usage.
----------------------------------
The CPU usage isn't an issue, as I have a 6-core Dell Inspiron, but I do see a slight video degradation. I did replace my VGA cable with a DVI-to-HDMI cable, but that didn't help. Can anyone tell me what my options are to re-enable hardware acceleration?
