# Oolite

From ArchWiki

Oolite is a space trading / sim game based on the well-known Elite game from the 80's.

## Installation

Install the ooliteAUR package.

## Troubleshooting

Oolite uses shaders extensively which may not work well with all drivers, especially the gallium OSS drivers.

By default Oolite starts with full shaders, if it hangs on the title screen please follow these 3 steps:

### Testing for shader problem

Run Oolite from terminal with this command:

    LIBGL_ALWAYS_INDIRECT=1 oolite

If Oolite works, the problem is with the shaders. In case this does not help, you have a different problem. Post about this on the Arch Linux forums or register a bug.

### Verify which setting works

Open `~/GNUstep/Defaults/.GNUstepDefaults` in an editor, scroll down and to the bottom, and look for these lines:

    <key>shader-mode</key>
    	<integer>3</integer>

Try changing the value of this key to 2 and 1 and test if Oolite runs normally (WITHOUT LIBGL_ALWAYS_INDIRECT stuff).

Note: The lines with shader-mode key are not always present, but it is safe to add them.

### Feedback

For the value of shader-mode that works, please post `~/.Oolite/Logs/Latest.log` on the Oolite forum, along with the highest shader-mode value that works for you.

This info will be used to determine the correct default shader setting for Oolite for your card/driver combination. This will then become part of the Oolite graphics configuration data in a later version.

Reason: Fixed as of Oolite 1.84 (Discuss in Talk:Oolite)

Mesa 8.0.2 has no problems i am aware of running oolite with shaders, but Oolite 1.76 still disables shaders for this driver.

If you wish to use shaders:

1. Execute `cp /usr/share/oolite/Resources/Config/gpu-settings.plist ~/.Oolite/AddOns` as USER
2. Edit `~/.Oolite/AddOns/gpu-settings.plist` and replace SHADERS_OFF (2 times) with SHADERS_FULL in the section shown below

    "ATI R600/R700 family (X/Gallium3D)" =
    {
    	/*
    		We have reports of Oolite hanging when using Gallium3D on AMD R600/R700 family GPUs with
    		shaders enabled. As a stopgap, we forcibly disable shaders on affected systems.
    		See http://aegidian.org/bb/viewtopic.php?f=9&t=9416
    	*/

    	match =
    	{
    		vendor = "X\\.Org";
    		renderer = "Gallium .*(?:AMD|AT[Ii]) R[A-Za-z]?[67]\\d{2}(?!\\d)";
    	};
    	maximum_shader_level = "SHADERS_OFF";
    	default_shader_level = "SHADERS_OFF";
    };
