The globals subsection specifies the configuration to apply globally to Screen.
This section must begin with begin globals and end with end globals.
There can only be one globals section. Parameters that are set in this section are applied to all pipelines.
Below is an example of a globals section of a graphics.conf file.
begin globals blit-config = pvr2d blits-logsize = 4096 end globals
The following are valid parameters that can be configured under the globals subsection:
| Parameter | Description | Type | Possible value(s) |
|---|---|---|---|
| alloc-config |
The name of the module used for buffer allocation. Screen uses the
following algorithm to determine the blitter module to load:
"screen-" + <value of alloc-config> + ".so"This configuration is platform-specific, and it's already set in the graphics.conf provided to you for your platform. We don't recommend changing this configuration from its original value. |
string | imx6xbuf |
| blit-config |
The blitter used when your application explicitly calls
the native blit API functions (screen_blit() and
screen_fill()). Screen uses the
following algorithm to determine the blitter module to load:
"screen-" + <value of blit-config> + ".so" Note:
Only one blitter can be configured. The selection of valid blitters depends on your platform; there can be multiple blitter values available for your particular platform. This parameter differs from the blitter specified in the usage parameter under your class section in graphics.conf. The blitter specified in the usage parameter is the blitter that Screen uses for composition. |
String |
sw (default) pvr2d bv-j5 gles2blt |
| blits-logsize | The size (in bytes) of an internal working ring buffer. | Integer |
0 to 4,294,967,295 |
| default-display |
The primary display. Identify the primary display by using the display_id that's used to define your displays in the display section of graphics.conf. This is typically a port number, or you can specify a string value. This parameter is valid only if your system supports displays. |
String | A numeric value specifying the port number or one of these string values:
|
| gesture-logsize | The size (in bytes) of an internal working ring buffer. | integer | 0 to 4,294,967,295 |
| idle-timeout | The number of seconds after which the system will enter an idle state. | long integer | 0 to 4,294,967,295 |
| input |
Human interface device (HID). This parameter can be configured with multiple values. If you don't specfiy input at all in your configuration file, Screen defaults to include all input (i.e., the same as if you had specified input = gamepad joystick keyboard mouse). Specify none (with no other valid input string) to explicitly disable all input. Note:
If you specify any valid input string other than none,
you must ensure that you have io-hid running before starting screen;
you must also have libhiddi.so in your LD_LIBRARY_PATH.

String |
gamepad joystick keyboard mouse none |
| input-logsize | The size (in bytes) of an internal working ring buffer. | Integer |
0 to 4,294,967,295 |
| joystick-logsize | The size (in bytes) of an internal working ring buffer. | Integer |
0 to 4,294,967,295 |
| keyboard-logsize | The size (in bytes) of an internal working ring buffer. | Integer |
0 to 4,294,967,295 |
| keymap | The location of all keymap files and/or the name of the default keymap file to use when a new keyboard device is created. This parameter is applicable only to HID keyboards. This parameter is optional. If keymap isn't set, then Screen uses /usr/share/keyboard/en_US_101. | String | /usr/share/keyboard/en_US_101 (default) |
| pointer-logsize | The size (in bytes) of an internal working ring buffer. | Integer |
0 to 4,294,967,295 |
| queue-start-size | The size of the event queue per context. Events for the context, such as input events, are put into this queue. This queue size doesn't grow if there are more events than the queue size specified. This means that applications may lose events if they aren't handled before more events are queued to beyond the queue's capacity. | Integer | 20 (default) |
| requests-logsize | The size (in bytes) of an internal ring buffer. | Integer | 0 to 4,294,967,295 |
| shortcuts | The string to append to the keymap name before the .kbd extension. The keymap name, this string, and the .kbd extension altogether identify the filename of the keymap file that's used when a window isn't in text-entry mode. | String | 0 to 65535 |
| stack-size | The stack size (in units of bytes) that Screen is to use for its threads. This stack-size must be configured appropriately for blitters/compositors that are using Mesa (e.g., gles2blt). The default stack size of is insufficient for these types of blitters/compositors. | Integer | 0 to 4,294,967,295 Example: 2097152 |
| touch-logsize | The size (in bytes) of an internal working ring buffer. | Integer | 0 to 4,294,967,295 |
