Title: Screen went blank after changing resolutions (SOLVED)
Post by: JonOfLA on August 03, 2019, 06:04:14 pm
Hi All.

I recently changed my screen resolution using the Peppermint Control Center, but it caused the screen to go black. When I reset it boots but then it goes to the black screen. I am able to use the command line page with control alt F1. I tried using the xrandr command to change the resolution back, but it gives the response can not display. Any ideas on how I can change the resolution back? Or how can I fix xrandr? Thanks.

Does booting the previous kernel make graphics work ?

If you don't know how, just ask.

Hi. I'm afraid I don't know how to boot the previous kernel. Can you help me with that? Thanks.

Immediately after turning on the PC, after the BIOS POST screen hit and hold the "Shift" key .. hopefully you'll eventually see the GRUB menu.

In the GRUB menu move down to "Advanced options" and hit enter.

In the submenu you just entered, select the top item and hit enter to boot.

OK, so please

Only you can do this, and it is done by going back to the first message in this thread, then clicking on the Modify button and then adding (SOLVED) at the end of the Subject: line.  ;)

Thank you.
