Since not everything runs under Wayland (default of Ubuntu 22.04), such as OpenGLGadget (gl_area not supported) or engine3d, you can change the gdk_backend to x11 for the application.

Also for the problem with the window sizes of PB. (Or use Workaround Wayland)

Without setting the gdk_backend yourself, you can also start a program with it.

Code: Select all

;-TOP by mk-soft, v1.01.1, 25.04.2022

Procedure RunAsX11()
  Protected SessionType.s, GdkBackend.s
  Protected Program.s, Parameters.s, cnt, index
  
  cnt = CountProgramParameters()
  If cnt = 0
    Program = OpenFileRequester("Open Program", "", "", 0)
    If Program = ""
      ProcedureReturn 0
    EndIf
  Else
    Program = ProgramParameter(0)
    cnt - 1
    For index = 1 To cnt
      Parameters + ProgramParameter(index)
      If index < cnt
        Parameters + " "
      EndIf
    Next
  EndIf
  
  SessionType = GetEnvironmentVariable("XDG_SESSION_TYPE")
  GdkBackend = GetEnvironmentVariable("GDK_BACKEND")
  If SessionType <> "x11"
    If GdkBackend <> "x11"
      SetEnvironmentVariable("GDK_BACKEND", "x11")
    EndIf
  EndIf
  ProcedureReturn RunProgram(Program, Parameters, "")
EndProcedure

End RunAsX11()

For example, start the PureBasicIDE to test as x11 programs.
