So when ever I print something to the console the first line (and only
the first) starts with some cryptic characters and I don't know how to
fix the issue. I am on Ubuntu and installed the latest lazarus-ide
version (1.8.4). The issue only surfaces when I use the CRT package,
if it isn't included no problems arise. What can I do to solve this
problem?

Hello dankmarius,
Welcome to the forum.

The binary created using Lazarus/FPC works perfectly. Just don't run
it using Lazarus Terminal Output (Ctrl+Alt+O), you should run it using
the Terminal provided by your Ubuntu.

Just curious, what was the correct text in the first line?

Below is the code and the console output using Lazarus Terminal
Output.

The bug already existed since first time I used Lazarus on Ubuntu. But
because I think it wasn't critical and I do not write console program,
I just ignore it. The result binaries will show correctly if I run
them using the Terminal provided by Ubuntu.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i program
Project1; uses  Crt; begin  WriteLn('Hello');  WriteLn('World.'); 
ReadLn;end.

Thank you!

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
//Laz\fpc\3.0.4\source\packages\rtl-
console\src\unix\crt.ppInitialization...   { Get current X,Y if not
set already }     GetXY(CurrX,CurrY);     if (CurrX=0) then     
begin        CurrX:=1;        CurrY:=1;        ttySendStr(#27'[H');  
  end;   {Reset Attribute (TextAttr=7 at startup)}     
ttySendStr(#27'[m');..

GetXY(var x,y:byte);...  s:=#27'[6n';  fpWrite(0,s[1],length(s));..
Edit:
ESC 0 J: clear from cursor to end of the screen.
ESC 1 J: clear from cursor to beginning of the screen.
ESC 2 J: clear entire screen.
