Re: [JAVA2D] vertical synchronization in full screen exclusive mode problem
I use the default xorg.conf on my ubuntu 8.04, on a system with Nvidia chip. Note that I _don't_ use the NVIDIA's proprietary drivers, and the default window manager is used. I have the following relevant extensions (as reported by xdpyinfo) DOUBLE-BUFFER RANDR In this configuration the full screen exclusive mode (including display mode changing) is supported and works fine. However, the OpenGL pipeline couldn't be enabled, the proprietary drivers are required for that. The vsync doesn't seem to be working (in 6u10) in this config. Our experiences starting to converge now. With the 6u10 I got both ubuntu and Fedora go into FSEM. Display mode change is possible. Only vsync still fails. But somehow even with the proprietary NVidia module and opengl extensions, I was able to get FSEM. I guess you have a point that there are so many possible configurations options on Linux... If you feel that this change in behavior is something that needs to be addressed, I encourage you to contact IcedTea guys, see if they could come up with a fix which we can incorporate into the openjdk source base.

Re: [JAVA2D] vertical synchronization in full screen exclusive mode problem
My latest version of VSyncApplet toggles between the use of Image and BufferedImage for simple drawing. Both are rendered to the screen with BufferStrategy. I see disturbing results. BufferedImages are half as fast as Image for simple drawing. I'm probably doing something wrong. Any improvement in the code will be appreciated.

Re: [JAVA2D] vertical synchronization in full screen exclusive mode problem
I think you misunderstand my intentions. The applet shows a profound defect in the Java2D API. Either the applet is wrong or the Java2D API needs work. I'm trying to illuminate the problem with my applet. If the applet uses the Java2D API wrong when I use standard programming strategies, then let's figure out why and fix it. If you think you are contributing to a constructive dialog with your comment then maybe you should rethink your perspective. Or not. I really don't care much what you think.

Re: [JAVA2D] vertical synchronization in full screen exclusive mode problem
I've done (redone the wheel likely) a fake full screen code. I'm not going to
spam the forum again with it. The only thing that changed is that the
construtor now starts with the correct (hopefully) size:
...
setExtendedState(MAXIMIZED_BOTH);
Insets i = getToolkit().getScreenInsets(getGraphicsConfiguration());
Rectangle max = new Rectangle(getToolkit().getScreenSize());
max.x += i.left;
max.y += i.top;
max.width -= i.right;
max.height -= i.bottom;
setBounds(max);
...
and the awteventlistener is now:
public void eventDispatched(AWTEvent e) {
WindowEvent evt = (WindowEvent) e;
if (PROCESS_WINDOW_EVENTS evt.getID() ==
WindowEvent.WINDOW_DEACTIVATED evt.getWindow() == JFrame.this
evt.getOppositeWindow() == null JFrame.this.isFullScreen()) {
JFrame.this.setExtendedState(JFrame.ICONIFIED);
}
I haven't seen problems with on linux java 1.6 with the additional
evt.getWindow() == JFrame.this, but i'm not sure about 1.5 anymore (don't have
it).
There is a small problem with the order on the alt-tab on windows (it doesn't
move to the selected aplication, but keeps on the last - i have no idea why).

[JAVA2D] vertical synchronization in full screen exclusive mode problem
Hi all,
I can get vertical synchronization in full screen exclusive mode with JDK1.5
but not with JDK1.6. I am using the strategy outlined at
http://java.sun.com/javase/6/docs/api/java/awt/image/BufferStrategy.html. I
tested this on two systems and the outcome is the same. The systems are:
System 1:
OS: Linux-x86_64 (Fedora 8)
Graphics card: NVidia Quadro FX 570M
NVIDIA Driver Version: 173.14.09
X Server: Xorg version 1.3.0.0
System 2:
OS: Linux-x86 (Ubuntu 8.04)
Graphics card: NVidia GeForce Go 6400
NVidia driver version: 169.12
X Server: Xorg 1.4.0.90
I tested the same code on these two systems enabling/disabling opengl pipeline
(-Dsun.java2d.opengl=True/False) and with jdk1.5 and jdk1.6. The only
combination where I get the correct behavior is jdk1.5 and opengl pipeline
enabled (on both systems). (Note on a Windows XP machine it works with both
JDK1.6 and 1.5)
Here is a part from the code:
createBufferStrategy(2);
bs = getBufferStrategy();
for (int j = 0; j nRepeat; j++)
for (int i = 0; i = getWidth() - bi.getWidth(); i += bi.getWidth())
displayImage(i, y, bi);
...
public void displayImage(int x, int y, BufferedImage bi) {
do {
do{
Graphics g = bs.getDrawGraphics();
g.setColor(getBackground());
g.fillRect(0, 0, getWidth(), getHeight());
g.drawImage(bi, x, y, null);
g.dispose();
}while(bs.contentsRestored());
bs.show();
}while(bs.contentsLost());
}
Expected outcome is a bar smoothly moving from left to right (bi is just that,
a vertical bar) on a black background.
Any ideas? Thank you.

Re: [JAVA2D] vertical synchronization in full screen exclusive mode problem
Do you feel like posting the whole code? I'd like to
turn it into an applet for test purposes. It
would be an excellent test program.
I'll repost it as an applet.

Have you tried windowed mode on the same systems with 6.0 or 5.0?
Do you get vsync then?

Well, I made an applet that I don't think really demonstrates much. It just moves a bar across the screen -- 1 pixel per draw. The numbers in the lower left is the approximate number of frames per second. You can enter fullscreen (exclusive?) mode by pressing F1 and exit with ESC.
