The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Also, removed the Maintained by, as requested by Geert.

What is lxfb?
|
|
=============

This is a graphics framebuffer driver for AMD Geode LX based processors.
|
|
|
|
Advantages:
|
|
|
|
* No need to use AMD's VSA code (or other VESA emulation layer) in the
|
|
BIOS.
|
|
* It provides a nice large console (128 cols + 48 lines with 1024x768)
|
|
without using tiny, unreadable fonts.
|
|
* You can run XF68_FBDev on top of /dev/fb0
|
|
* Most important: boot logo :-)
|
|
|
|
Disadvantages:
|
|
|
|
* graphic mode is slower than text mode...
|
|
|

How to use it?
|
|
==============
|
|
|
|
Switching modes is done using lxfb.mode_option=<resolution>... boot
|
|
parameter or using `fbset` program.
|
|
|
|
See Documentation/fb/modedb.rst for more information on modedb
|
|
resolutions.

|
XF68_FBDev should generally work fine, but it is non-accelerated.
|
|
|
|
|
|
Configuration
|
|
=============
|
|
|
|
You can pass kernel command line options to lxfb with lxfb.<option>.
|
|
For example, lxfb.mode_option=800x600@75.
|
|
Accepted options:
|
|
|
|
================ ==================================================
|
|
mode_option specify the video mode. Of the form
|
|
<x>x<y>[-<bpp>][@<refresh>]
|
|
vram size of video ram (normally auto-detected)
|
|
vt_switch enable vt switching during suspend/resume. The vt
|
|
switch is slow, but harmless.
