How to change the display resolution?

Question

Screen resolution

I got a Raspberry pi 3 the other day with a 3.5 TFT LCD display. It connects to the board via GPIO. I was able to connect. Can you tell me how to increase the resolution, otherwise at 480 × 320 the windows are not completely displayed and I do not see the command (reducing the size of the windows themselves does not help either). UBUNTU MATE operating system. I'm just getting started with Linux in general.

Answer 1

It is possible to change the permission through the xorg.conf configuration file,
another way to change it is through xrandr -s 800x600

Answer 2

Most likely you won't get anything. There are 2 options - use optimized software (in this situation, I advise you to try Raspbian) or play with scaling)

Answer 3

It looks like you made a mistake, bought a display not suitable for your tasks. If you need a full-fledged desktop operating system, then the display had to be taken in the appropriate size and, most importantly, the appropriate resolution. Or even use a regular monitor / TV. And this three-inch kid is suitable, for example, as an indicator for homemade products based on Malinka - some kind of control device, player, watch with a thermometer, etc. Well, or, as already said, try using Raspbian. There seems to be versions for such a display.

Answer 4

after all, a lot of time has passed, but if suddenly someone searches, go to the file /boot/config.txt and at the end add the lines
framebuffer_width = 1024
framebuffer_height = 768
save the file (edit only from root - for this, right-click and select Open as superuser)
Pick the numbers that are comfortable for you. You will be happy. I searched for a long time until the dude suggested it on the forum. In this file, a lot of interesting things are stored by the way.
