32bit games in fullscreen?

hey!

i am programming my own games in blitzmax, which is 32bit and therefore i installed a 32bit chroot. everything runs fine and i can compile and run my games. BUT only in windowed mode. if i try to run them in fullscreen mode i will get a black screen and the game stops running.
i think this is not a blitzmax issue so i post it here. do i need a special lib to run 32bit opengl games in fullscreen mode?

Re: 32bit games in fullscreen?

ok here is the debug message i receive if i start a 32bit game in fullscreen mode (windowed mode runs fine!):

Re: 32bit games in fullscreen?

@Danvari: Hmmm...I had a similar error trying to get the citrix client working. Now I can run it with a little script that sets the SLOPPY LOCK environmental variable and that seems to fix the problem

#!/bin/sh
export LIBXCB_ALLOW_SLOPPY_LOCK=1 # Fix for Citrix client
schroot -pc arch32 /usr/lib/ICAClient/wfica $1

Maybe that will help?

Good luck,
Scott

Re: 32bit games in fullscreen?

no that does not work for me :-\

ok i programmed a small program:
http://rapidshare.com/files/150305643/demo.debug.html

it would be nice if you could test it on your arch64 machine. for me it does not work. and it worked quite well under gentoo amd64, so i think it has nothing to do with blitzmax, the programming language (it compiles in gcc)

run:

./demo.debug           for windowed mode...that one works. you will get a simple "Test" in the upper left corner.
./demo.debug --fullscreen      for fullscreen mode....does not work, you have to kill it and you will get an error message :-\

that is the source code (although you need blitzmax):

AppTitle = "Test"

If Len(AppArgs) = 2 Then
    If AppArgs[1] = "--fullscreen" Then Graphics 640, 480, 32 
Else
    Graphics 640, 480
End If

Repeat
    Cls()
    DrawText "Test", 0, 0
    Flip()
Until KeyDown(KEY_ESCAPE)

does not work either in 32bit, 24bit or 16bit, same behaviour..
