Abstract

A computing system with a graphical windowing server displaying to a display, and a method for setting the resolution of a display to which a computing device displays. The method comprises running a graphical windowing server with a digital connection enabled between the display and a graphics adapter for the display, querying the display with the digital connection for display modes supported by the display, receiving returned mode data, the mode data being indicative of one or more display modes supported by the display, shutting down the graphical windowing server, composing a modeline for the display according to the returned mode data and a desired resolution, running the graphical windowing server with the digital connection disabled and the modeline, and loading a graphics specification corresponding to the resolution indicated by the modeline.

Claims

1. A method of setting the resolution of a display to which a computing device with a graphical windowing server displays, comprising:

running the graphical windowing server with a digital connection enabled between the display and a graphics adapter for the display;

querying the display with the digital connection for display modes supported by the display;

receiving returned mode data, said mode data being indicative of one or more display modes supported by the display;

shutting down the graphical windowing server;

composing a modeline for the display according to the returned mode data and a desired resolution;

running the graphical windowing server with the digital connection disabled and the modeline; and

loading a graphics specification corresponding to the resolution indicated by the modeline.

2. A method as claimed in claim 1, wherein the graphical windowing server comprises an X based graphical window server, the digital connection comprises a Display Data Channel and the graphics specification is contained in an Xresources file.

3. A method as claimed in claim 1, comprising selecting the desired resolution according to a resolution or resolutions identified by the returned mode data.

4. A method as claimed in claim 1, wherein composing the modeline comprises modifying a resolution identified by the returned mode data according to the desired resolution.

5. A method as claimed in claim 1, wherein the mode data comprises a modeline or modelines.

6. A method as claimed in claim 1, wherein querying the display comprises controlling the graphical windowing server to query the display with the digital connection.

7. A method as claimed in claim 1, wherein the graphical windowing server comprises an X based graphical window server, the digital connection comprises a Display Data Channel and the graphics specification is contained in an Xresources file, and wherein querying the display comprises controlling the X based graphical window server to query the display with the Display Data Channel by executing an xrandr utility program.

8. A method as claimed in claim 1, comprising saving the returned modeline data.

9. A method as claimed in claim 1, comprising writing the returned modeline data to a file.

10. A method as claimed in claim 1, comprising conducting a search of the returned mode data for data indicative of one or more supported or desired graphics standards or resolutions.

11. A method as claimed in claim 10, wherein the one or more graphics standards or resolutions comprises VGA.

12. A method as claimed in claim 10, wherein the one or more graphics standards or resolutions comprises a number of columns.

13. A method as claimed in claim 10, wherein the one or more graphics standards or resolutions comprises a number of rows.

14. A method as claimed in claim 1, wherein loading the graphics specification comprises controlling the graphical windowing server to load the graphics specification.

15. A method as claimed in claim 1, wherein the graphical windowing server displays to a plurality of different displays, and the method comprises setting the resolution of each of the plurality of displays to respective different resolutions.

16. A method as claimed in claim 1, wherein the graphical windowing server displays to a plurality of different displays, and the method comprises setting the resolution of each of the plurality of displays to an identical resolution.

22. A method as claimed in claim 1, further comprising executing a computer program code.

23. A method as claimed in claim 22, further comprising storing in a computer readable medium said computer program code.

24. A method as claimed in claim 1, further comprising

transmitting data packets of computer program code;

and

executing said computer program code.

17. A computing system with a graphical windowing server displaying to a display, the computing system arranged to:

run the graphical windowing server with a digital connection enabled between the display and a graphics adapter for the display;

query the display with the digital connection for display modes supported by the display;

receive returned mode data, said mode data being indicative of one or more display modes supported by the display;

shut down the graphical windowing server;

compose a modeline for the display according to the returned mode data and a desired resolution;

run the graphical windowing server with the digital connection disabled and the new modeline; and

load a graphics specification corresponding to the resolution indicated by the new modeline.

18. A computing system as claimed in claim 17, wherein the graphical windowing server comprises an X based graphical windowing server, the digital connection comprises a Display Data Channel and the graphics specification is contained in an Xresources file.

19. A computing system as claimed in claim 17, wherein the computing system is arranged to conduct a search of returned mode data for data indicative of one or more desired or supported graphics standards or resolutions.

20. A computing system as claimed in claim 17, and comprising a gaming machine.

21. A computing system as claimed in claim 17, and comprising a gaming system.
