Set optional EGL configuration specfiers. These optional configuration specifiers are set using a comma-separated list. The specifiers may include the following: pixel format and/or multi-sampling specifications, or an EGL configuration number. If you're using an EGL configuration number, it must not be specified with other specifiers.
Specify pixel format as one of the following:
where "a" indicates alpha bits and "x" indicates ignored bits.
Specify multi-sampling as:
[rate]x
where rate is a valid sampling rate (e.g., 2, 4, 8, ...).
For example, the following are all valid ways of specifying the EGL configuation option:
If no specific EGL configuration is provided, this utility gets the RGB pixel format with the smallest bit depth supported by the hardware.
Set the display, as an integer to show content. Use the EGL display ID that's been configured in the khronos section of your configuation file, graphics.conf.
If no EGL display ID is provided, then this utility uses the default display.
The gles2-gears binary is a command-line tool that can be used to confirm that screen is running, and that all necessary drivers for OpenGL ES 2.x are in place, and can start successfully.
To run gles2-gears:
# gles2-gears
