I am using AUTODETECT in my program. But it seems that it doesnt work properly in linux. Should I neccesserily use AUTODETECT on all platforms. In linux AUTODETECT fails but GFX_XWINDOWS works fine. What are safe GFX options. though I will allow to pass custom driver through config file. ------------------------------------- |

thats the problem with linux. no standard and/or too many config options. therefore such things as AUTODETECT will sometimes fail. the answer i guess you dont want to hear is.. linux' freedoms are also its downfall. ___________________________ |

What's the error you get with GFX_AUTODETECT? -- |

That's strange. It works perfectly here (and currently, Allegro's Linux port is probably the best tested of all). Quote: Should I neccesserily use AUTODETECT on all platforms. Yes. Quote: In linux AUTODETECT fails but GFX_XWINDOWS works fine. That makes no sense, as GFX_XWINDOWS should be the driver used by GFX_AUTODETECT anyway. There is a way to check which driver is selected: can you print out gfx_driver->ascii_name after calling set_gfx_mode() (ie, printf("%s\n", gfx_driver->ascii_name); - be sure to run your program from an xterm). |

I ma using allegro 4.1.16, X version [cant remember Quote: What's the error you get with GFX_AUTODETECT? A black screen and goes off in a hurry. Quote: [Quote] Yes.</quote> So, I dont need config file to pass custom driver, anyway if I want, where all other graphics driver defined.. in gfx.c I can find only GFX_AUTODETECT Quote: That makes no sense, as GFX_XWINDOWS should be the driver used by GFX_AUTODETECT anyway.

I will do that next time; when I login to linux ------------------------------------- |

You should try to print out allegro_error and see what it says. Quite a few Allegro functions will set that if they fail (the init functions, anyway). -- |

Quote: anyway if I want, where all other graphics driver defined.. In platform specific headers. You really have no need to delve into that unless you're going to change anything in Allegro itself. They're documented anyway (see the platform specific section of Allegro's manual). EDIT: Quote: I ma using allegro 4.1.16, X version Note that there is no such thing as `the X version of Allegro' in the proper sense of the word (although it is sometimes refered to as `the X11 port' what that means is `the UNIX port using the X11 system driver'). The X11 version is the same as the console version is the UNIX version. That means that Allegro will compile fine if you don't have the X11 headers and development libraries installed, but it won't use X, which may not be what you expect. |

Will allegro programs run in terminal without X. Can I compile allegro with some floppy size linux and run a piece of allegro code in fullscreen with fancy graphics. ------------------------------------- |

Yes to (potentially) all. I believe Allegro can do VGA 13h on it's own, but beyond that you'll need SVGALib, fbcon, or VBE/AF (which isn't well supported). -- |

Are you running as root? Then Allegro would pick the DGA(2?) driver, and this one may be failing for you. -- |

Because the X11 driver should be the default one and it does work. |
