Hello,

Since yesterday, the resolution is stuck at 1024x768 and that is now the maximum value offered in the settings, whereas before I was in Full HD (1920x1080).

It started the day before yesterday with the screen switching several times from one resolution to another.

The computer is from 2010, just like the graphics card, which is an AMD Radeon HD 5400.

I don't know how to determine if it's a software issue (AMD driver) or hardware.

Thank you in advance for your help.

Hello,

What is the model of your video card? 

lspci | egrep "3D|VGA"


What drivers are currently installed? 

dpkg -l | grep xserver-xorg-video


Good luck.
