Linux Installation Problems (Ubuntu 7.10)

[Zatarg]

Hello.

After extracting the files, I tried to run

java -cp .:res:jar/lwjgl.jar:jar/lwjgl_test.jar:jar/lwjgl_util.jar:jar/lwjgl_fmod3.jar:jar/lwjgl_devil.jar:jar/jinput.jar: -Djava.library.path=native/linux org.lwjgl.test.WindowCreationTest

from the command line.

A window did appear, but all it did was fade between black and white background.  The title of the window was "Game".

The cmd line said:

The following keys are available:
ESCAPE:         Exit test
ARROW Keys:     Move window when in non-fullscreen mode
L:              List selectable display modes
0-8:            Selection of display modes
F:              Toggle fullscreen
SHIFT-F:        Toggle fullscreen with Display.destroy()/create() cycle

On trying to switch to fullscreen i get

WindowCreation test is kind of Windows centric with its multiple bit depths and what not. On linux, there's only one bit depth so a few modes will not be located and are null, which is perfectly normal.

Failing to switch modes are a real problem, though. Try to enable debugging (-Dorg.lwjgl.util.Debug=true) and see if there's some useful hints before the exception. Also see if xrandr works at all by switching display mode manually (use the 'xrandr' tool or some equivalent GUI).

The native path is probably wrong. Why is -Djava.library.path different than the other runs?

If xrandr is somehow broken on your setup (if fullscreen works immediately after a reboot, you're probably running into a known (but fixed in X 7.3) bug with xrandr) then try disabling xrandr by using the switch -DLWJGL_DISABLE_XRANDR=true.
