UPDATED: video mode changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Based on some feedback, I have modified this patch a bit:

- remove MESSAGE in favor of TRACE
- return 32bpp instead of 24bpp for truecolor modes
- ignore the mode change if we are already in the desired mode
