I installed Kubuntu yesterday, and when I logged in I noticed that the resolution was stuck at 1024x768 and lower.
So I added a new resolution via the GRUB config text file (1366x768 @60). But when I added the resolution and used it, it stayed in a 4:3 aspect ratio like 1024x768 in Display Configuration. I am new to Ubuntu/Kubuntu and Linux in general. I have no idea what is happening.
Device specifications:
