E.g.: insmod bttv vidmem=0xfb0 remap=0xfa0 - - If the video memory is found at the right place and there are no address - conflicts but still no picture (or the computer even crashes), - try disabling features of your PCI chipset in the BIOS setup. - - Frank Kapahnke <frank@kapahnke.prima.ruhr.de> also reported that problems - with his S3 868 went away when he upgraded to XFree 3.2. - - -- I still only get a black picture with my S3 card! - - Even with XFree-3.2A some people have problems with their S3 cards - (mostly with Trio 64 but also with some others) - Get the free demo version of Accelerated X from www.xinside.com and try - bttv with it. bttv seems to work with most S3 cards with Accelerated X. - - Since I do not know much (better make that almost nothing) about VGA card - programming I do not know the reason for this. - Looks like XFree does something different when setting up the video memory? - Maybe somebody can enlighten me? - Would be nice if somebody could get this to work with XFree since - Accelerated X costs more than some of the grabber cards ... - - Better linear frame buffer support for S3 cards will probably be in - XFree 4.0. - -- Grabbing is not switched off when changing consoles with XFree. - That's because XFree and some AcceleratedX versions do not send unmap - events. - -- Some popup windows (e.g. of the window manager) are not refreshed. - - Disable backing store by starting X with the option "-bs" - -- When using 32 bpp in XFree or 24+8bpp mode in AccelX 3.1 the system - can sometimes lock up if you use more than 1 bt848 card at the same time. - You will always get pixel errors when e.g. using more than 1 card in full - screen mode.
