5 | - The memory of some S3 cards is not recognized right: | |

7 | First of all, if you are not using XFree-3.2 or newer, upgrade AT LEAST to |
8 | XFree-3.2A! This solved the problem for most people. | |
9 | ||
10 | Start up X11 like this: "XF86_S3 -probeonly" and write down where the | |
11 | linear frame buffer is. | |
12 | If it is different to the address found by bttv install bttv like this: | |
13 | "insmod bttv vidmem=0xfb0" | |
14 | if the linear frame buffer is at 0xfb000000 (i.e. omit the last 5 zeros!) | |
15 | ||
16 | Some S3 cards even take up 64MB of memory but only report 32MB to the BIOS. | |
17 | If this 64MB area overlaps the IO memory of the Bt848 you also have to | |
18 | remap this. E.g.: insmod bttv vidmem=0xfb0 remap=0xfa0 | |
19 | ||
20 | If the video memory is found at the right place and there are no address | |
21 | conflicts but still no picture (or the computer even crashes), | |
22 | try disabling features of your PCI chipset in the BIOS setup. | |

24 | Frank Kapahnke <frank@kapahnke.prima.ruhr.de> also reported that problems | |
25 | with his S3 868 went away when he upgraded to XFree 3.2. | |

27 | ||
28 | - I still only get a black picture with my S3 card! | |
29 | ||
30 | Even with XFree-3.2A some people have problems with their S3 cards | |
31 | (mostly with Trio 64 but also with some others) | |
32 | Get the free demo version of Accelerated X from www.xinside.com and try | |
33 | bttv with it. bttv seems to work with most S3 cards with Accelerated X. | |

35 | Since I do not know much (better make that almost nothing) about VGA card |
36 | programming I do not know the reason for this. | |
37 | Looks like XFree does something different when setting up the video memory? | |

38 | Maybe somebody can enlighten me? |
39 | Would be nice if somebody could get this to work with XFree since | |
40 | Accelerated X costs more than some of the grabber cards ... | |

42 | Better linear frame buffer support for S3 cards will probably be in |
43 | XFree 4.0. | |

45 | - Grabbing is not switched off when changing consoles with XFree. |
46 | That's because XFree and some AcceleratedX versions do not send unmap | |
47 | events. | |
48 | ||
49 | - Some popup windows (e.g. of the window manager) are not refreshed. | |

51 | Disable backing store by starting X with the option "-bs" |
52 | ||
53 | - When using 32 bpp in XFree or 24+8bpp mode in AccelX 3.1 the system | |
54 | can sometimes lock up if you use more than 1 bt848 card at the same time. | |
55 | You will always get pixel errors when e.g. using more than 1 card in full | |
56 | screen mode. Maybe we need something faster than the PCI bus ... | |
57 | ||
58 | ||
59 | - Some S3 cards and the Matrox Mystique will produce pixel errors with | |
60 | full resolution in 32-bit mode. | |
61 | ||
62 | - Some video cards have problems with Accelerated X 4.1 |
