Programs on Ubuntu 22.04
« on: March 01, 2024, 12:21:03 am »
Hi, I was using lazarus without problems, then installed LazPaint and it look like this, as well any lazarus app (including the IDE), black menus and strange font rendering.

I'm using a VM of Ubuntu 22.04 64.bit

The problem is that I do not know what is ubuntu default... I did a quick search but the answer was inconclusive whether or not ubuntu 22.04 uses wayland by default. In case it is then you have your answer. In that case there is usually a switch in the configuration setting/setup that allows you to switch to xwayland (or x).

Because I constantly stumble on pages like this I can only assume that wayland is the default server (and the page also shows you how to switch  :) )

check export, i.e. type export in a terminal. You will see if wayland is used or not. Look for this line:
Code: Bash  [Select][+][-]
  1. declare -x WAYLAND_DISPLAY="wayland-0"
or similar.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Yes I found that line. So it is wayland.

FYI.
I encounter many problems related to Wayland (and also GTK2) on modern Linux systems.
I have switched to QT5/QT6. Now, all apps run wonderful on any display server.
