Games fullscreen is distorted, but video fullscreen is fine - older laptop
 

Hello, I have a toshiba 4600 and am running antix on it.

I can watch video files fine in fullscreen, but when i run emulators like zsnes or snes9x or fceu, it goes fullscreen, but the picture does not cover the entire screen.

It's weird...it is like it just stretches the picture vertically, but there are black bars all around the sides. And the image isn't even centered. There is a huge black bar to the right and a smaller one to the left.

The video card is a cyberbladeXP.

Any ideas on what i can do here?

-Thanks

Videos in fullscreen are different from (most) other applications because they don't change the resolution in fullscreen mode (at least all video apps that I tried). Maybe try setting different resolutions in zsnes?

I've tried all the resolution options i could up to 1024x768 which is my screens native resolution. Only the resolutions that use open GL work, but when i use opengl it is so slow, like 2-3 fps.

Also, this behavior is exactly the same with all three of the emulators listed in my post.

Any other ideas?
-Thanks

Looks like bad/non-installed video card drivers to me. Please post the contents of the file /etc/X11/xorg.conf here; that should give some info about your graphics configuration.

Here is my xorg file. Some of the stuff in there has nothing to do with my video card, but this is the only xorg file i could find where i am able to use tv out on my laptop.

-Thanks for any help you can provide.

That's a lot of configuration in your file. Did you try starting X without any configuration file at all (with back-up(s), of course) ?

I see
on the posted xorg.conf. Is this the correct driver? The output of lspci can help determine the exact make/model of your video chipset. This may also explain the slow OpenGL (although some chipsets, namely SiS ones, are known not to support OpenGL acceleration under Linux. This may or may not be the case, though).

Another thing to note is that most laptops (for some time now) have wide-screen displays. The machines ZSNES, FCEU and such emulators emulate were designed for standard 4:3 TV screens. So the black bars on the sides of the screen may be there exactly to AVOID image distortion caused by wrong aspect ratio.

Hope this helps.

Hello and thanks for the replies. Starting up without an xorg file gives me a nice error. The driver should be trident as far as i can tell, since i'm using a Trident CyberbladeXP video card in this laptop.

It's an old laptop, and the screen is a 4:3 screen. Also, it's more than just black bars...you totally miss out on the bottom 150-200 pixels as they are below the screen. And the rest is squashed, so it's clearly tweaked.

-Thanks for any help.
