It uses the 19Amiga abstract graphic driver (grfabs) functions for the low-level 20display management. 21.Pp 22Currently it does not support running X. 23It can however coexist well enough with grf0 to make possible running 24X the old way, but be warned, you cannot switch screens while 25in X and when quitting it, it seems to hang. Switching a screen 26then will bring up the text console. As always, we apologise for 27the inconvenience. 28.Pp 29What it does support is hilite (bold), underline, reverse and 30foreground/background colors. 31.Ss Virtual terminals and screen types 32The number of virtual screens is limited only by 33the available chip memory. 34.Pp 35Each virtual screen can have a different screen type. 36A screen type defines the following things: height and width 37in pixels, number of colors, and font size. 38The supported screen types are listed below. 39.Bl -bullet -offset indent -compact 40.It 4180x64 - display size 640x512 with 8 colors, font size 8x8 42.It 4380x51 - display size 640x510 with 8 colors, font size 8x10 44.It 4580x50 - display size 640x400 with 8 colors, font size 8x8 46.It 4780x40 - display size 640x400 with 8 colors, font size 8x10 48.It 4980x32 - display size 640x512 with 8 colors, font size 8x16 50.It 5180x31 - display size 640x248 with 8 colors, font size 8x8 52.It 5380x25 - display size 640x400 with 8 colors, font size 8x16 54.It 5580x24 - display size 640x192 with 8 colors, font size 8x8 56.It 57default - same as either 80x64 or 80x50, depending on the presence 58of GRF_NTSC and GRF_PAL in the kernel configuration. 59.El 60.Pp 61The grfabs code determines the actual screen mode that is used. 62The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine 63what kind of chipsets/modes are available. 64.Ss Fonts 65Fonts of width 8 and any height are supported. 66Fonts can be compiled into the kernel by specifying "options FONT_[fontname]" 67in the configuration file, or loaded with the 68.Xr wsfontload 8 69utility runtime. 70.Sh SEE ALSO 71.Xr wscons 4 , 72.Xr wsdisplay 4 , 73.Xr wsfontload 8 , 74.Xr wsfont 9 75
