How to return to previous Kernel in Ubuntu

[RobertS]

I have installed a new kernel however it made my Steam games not work. To try to return to the previous one, I went into the boot menu, went onto advanced options then selected the previous version. I have been stuck on t a screen that says Ubuntu, and 2 white lights lot up for at least 3 hours now.  What have I done wrong?

what kernel did you install and how?

[RobertS]

I used UKUU and installed 4.19.0.041900 generic

Your graphics driver probably wasn't rebuilt correctly...

 

 

Some helpful thing to tell us if you still need help

uname -a; glxinfo ¡ grep OpenGL

I can't even get into the previous kernel. It is stuck on the screen that I attached when I select the previous one

Do you want me to go to the one that does not work?

uname -a; glxinfo ¡ grep OpenGL

I was stupid here.  I didnt add the pipe, i copied the upside down !.  Here is the output:

My fault, 'uname -a ; glxinfo | grep OpenGL'

 

Nvidia or AMD?  Can you run glxgears?

Appears fine...  does steam crash at launch or game start?  Can you give any debug log or start it from terminal & post the output

It's different for each game.  CS GO shows a black screen for 10 seconds then closes. Rocket League has no textures and runs at 10fps. I have reinstalled the games already and it didn't help

That's what I tried but it just hung on the attached screen

It wouldn't be the game, since glxgears runs, your graphics drivers appear to be working, they're from the ppa right?  You can reinstall the newest nvidia driver
