It uses the 18Amiga abstract graphic driver (grfabs) functions for the low-level 19display management. 20.Pp 21Currently it does not support running X. 22It can however coexist well enough with grf0 to make possible running 23X the old way, but be warned, you cannot switch screens while 24in X and when quitting it, it seems to hang. Switching a screen 25then will bring up the text console. As always, we apologise for 26the inconvenience. 27.Pp 28What it does support is hilite (bold), underline, reverse and 29foreground/background colors. 30.Ss Virtual terminals and screen types 31The number of virtual screens is limited only by 32the available chip memory. 33.Pp 34Each virtual screen can have a different screen type. 35A screen type defines the following things: height and width 36in pixels, number of colors, and font size. 37The supported screen types are listed below. 38.Bl -bullet -offset indent -compact 39.It 4080x64 - display size 640x512 with 8 colors, font size 8x8 41.It 4280x51 - display size 640x510 with 8 colors, font size 8x10 43.It 4480x50 - display size 640x400 with 8 colors, font size 8x8 45.It 4680x40 - display size 640x400 with 8 colors, font size 8x10 47.It 4880x32 - display size 640x512 with 8 colors, font size 8x16 49.It 5080x31 - display size 640x248 with 8 colors, font size 8x8 51.It 5280x25 - display size 640x400 with 8 colors, font size 8x16 53.It 5480x24 - display size 640x192 with 8 colors, font size 8x8 55.It 56default - same as either 80x64 or 80x50, depending on the presence 57of GRF_NTSC and GRF_PAL in the kernel configuration. 58.El 59.Pp 60The grfabs code determines the actual screen mode that is used. 61The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine 62what kind of chipsets/modes are available. 63.Ss Fonts 64Fonts of width 8 and any height are supported. 65Fonts can be compiled into the kernel by specifying "options FONT_[fontname]" 66in the configuration file, or loaded with the 67.Xr wsfontload 8 68utility runtime. 69.Sh SEE ALSO 70.Xr wscons 4 , 71.Xr wsdisplay 4 , 72.Xr wsfontload 8 , 73.Xr wsfont 9 74
