What is tgafb?
===============
This is a driver for DECChip 21030 based graphics framebuffers, a.k.a. TGA
cards, specifically the following models
ZLxP-E1 (8bpp, 4 MB VRAM)
ZLxP-E2 (32bpp, 8 MB VRAM)
ZLxP-E3 (32bpp, 16 MB VRAM, Zbuffer)
This version, tgafb-1.12, is almost a complete rewrite of the code written
by Geert Uytterhoeven, which was based on the original TGA console code
written by Jay Estabrook.
Major new features:
* Support for multiple resolutions, including setting the resolution at
boot time, allowing the use of a fixed-frequency monitor.
* Complete code rewrite to follow Geert's skeletonfb spec which will allow
future implementation of hardware acceleration and other features.
Configuration
=============
You can pass kernel command line options to tgafb with
`video=tga:option1,option2:value2,option3' (multiple options should be
separated by comma, values are separated from options by `:').
Accepted options:
font:X - default font to use. All fonts are supported, including the
SUN12x22 font which is very nice at high resolutions.
mode:X - default video mode. See drivers/video/tgafb.c for a list.
X11
===
XF68_FBDev should work just fine, but I haven't tested it. Running
the XF86_TGA server (reasonably recent versions of which support all TGA
cards) works fine for me.
One minor problem with XF86_TGA is when running tgafb in resolutions higher
than 640x480, on switching VCs from tgafb to X, the entire screen is not
re-drawn and must be manually refreshed. This is an X server problem, not a
tgafb problem.
Enjoy!
