Only PCI/AGP based cards are supported, -none of the older Tridents. -The driver supports 8, 16 and 32 bits per pixel depths. -The TGUI family requires a line length to be power of 2 if acceleration -is enabled. This means that range of possible resolutions and bpp is -limited comparing to the range if acceleration is disabled (see list -of parameters below). - -Known bugs: -1. The driver randomly locks up on 3DImage975 chip with acceleration - enabled. The same happens in X11 (Xorg). -2. The ramdac speeds require some more fine tuning. It is possible to - switch resolution which the chip does not support at some depths for - older chips. - -How to use it? -============== - -When booting you can pass the video parameter. -video=tridentfb - -The parameters for tridentfb are concatenated with a ':' as in this example. - -video=tridentfb:800x600-16@75,noaccel - -The second level parameters that tridentfb understands are: - -noaccel - turns off acceleration (when it doesn't work for your card) - -fp - use flat panel related stuff -crt - assume monitor is present instead of fp - -center - for flat panels and resolutions smaller than native size center the - image, otherwise use -stretch - -memsize - integer value in KB, use if your card's memory size is misdetected. - look at the driver output to see what it says when initializing. - -memdiff - integer value in KB, should be nonzero if your card reports - more memory than it actually has.
