Question White bars on LUbuntu

[henning-po]

I've recently installed LUbuntu on a computer of mine and it looked as nice as it could on a TV screen. I then installed my GPU drivers and restarted my PC then these bars showed up on the left and right side of my screen. They are in the foreground of everything.

What is the specs of your computer - and most important: what GPU do you have?

I found out what the problem was. I somehow activated some sidebars, but I got rid of it by righ-clicking on the bars and deleting them.
