Could not make context current (beta 4)

Swackhammer1 · December 12, 2006, 05:21:49

Hi,
I just installed the latest version of lwjgl and tried to run the command given in the installation instructions and got the following on my screen (along with a box that kept fading in and out)

C:\lwjgl-1.0beta4>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

The following keys are available:

SHIFT-F:        Toggle fullscreen with Display.destroy()/create() cycle

Then I pressed 'F' to get into Fullscreen mode and got the following error:

I'm using a Dell Inspiron 9400 with Windows XP SP2 and a Nvidia 7800 graphics card. My resolution is set to 1920 x 1200. (If you need that info)

Do you have your drivers installed

Swackhammer1 · December 12, 2006, 06:06:00

My video card drivers? Yes, they're installed.
I've run OpenGL programs on my machine before albeit using C++ and OpenGL directly.

Matzon · December 12, 2006, 11:55:53

wonder if it's a screen resolution thing?
can you try and append -Dorg.lwjgl.util.Debug=true ?

Swackhammer1 · December 12, 2006, 13:46:55

Well, I ran the command again, and this time I pressed 'F' right after it started. It went to Fullscreen mode without any problems.
I ran it a third time, repeating the steps I did the first time, i.e., pressing L to list all the modes then pressing '0' for 640 x 480 then pressing '3' for 800 x 600, pressing '6' for 1024 x 768 and finally pressing 'F' for Fullscreen mode and once again I got:

        at org.lwjgl.test.WindowCreationTest.main(WindowCreationTest.java:285)

btw, this was with the debug command added in.

And when I press 'L' only 0,3,6 are available modes (the ones I stated above). All others are 'null'. The available modes are x16 @60Hz. My video setting are set to 32 bit color.

Matzon · December 13, 2006, 11:38:10

might be a 16 bit vs 32 bit thing
not sure it's an lwjgl bug - probably more a bug in the test for not handling inability to set fullscreen.

Swackhammer1 · December 13, 2006, 17:31:01

so does that mean that lwjgl will run fine on my machine the way it is currently set? Or will I have to change something?

Hi

I have a similar error when trying to initialize 1024x768 24bits:

But the program runs very well on other machines and the graphic card drivers are installed. This is a WindowsXP SP2 machine. I have noticed of this issue in a set of machines with the same configurations and only is present in a subset of them.

Is this a problem of the machine or of my code?

I have another issue but I'm very surprised with it, look at the images, I only find this issue in one machine:

The configuration of this machine is:

Quoteso does that mean that lwjgl will run fine on my machine the way it is currently set? Or will I have to change something?

Could you print out the results from Display.getAvailableDisplayModes()? It looks like your card only supports 16bit color and the test is looking for 24 or 32 bit colors. So it should work fine if you just select 16 bit colors (just a guess

)

QuoteI have a similar error when trying to initialize 1024x768 24bits

My guess is that the display modes are listed as 32bits instead of 24bits.

QuoteI have another issue but I'm very surprised with it, look at the images, I only find this issue in one machine

Looks like a Unicode normalization issue, or a font issue... Does the the machine have the font you used? I would be surprised if it was a Unicode normalization issue, but that is what it looks like. I'm not sure how to normalize characters in Java, unfortunately.

Non-English characters can be nasty sometimes

Swackhammer1 · December 13, 2006, 21:38:32

My card does support 32 bit colors. That's why that was the default setting. Regarding the Display.getAvailableDisplayModes() could you tell me exactly what to do since this is the first time I'm using lwjgl.
Thanks.

paco · December 14, 2006, 14:31:56

I noticed that the "color tinting" issue and transparency occurs only in machines with Intel Graphics cards. It's very curious! The font is bitmap font, so no normalized font nor unicode transform ;-) The images show the tinted images in black and red (they are full color) issue.

I'll check the "getAvailableDisplay" ;-) and I will back with the results ;-)

Thanks very much.

Paco.
