2lxfb - AMD Geode LX framebuffer driver
3======================================
4
5This is a graphics framebuffer driver for AMD Geode LX based processors.
6
7Advantages:
8
9 * No need to use AMD's VSA code (or other VESA emulation layer) in the
10 BIOS.
11 * It provides a nice large console (128 cols + 48 lines with 1024x768)
12 without using tiny, unreadable fonts.
13 * You can run XF68_FBDev on top of /dev/fb0
14 * Most important: boot logo :-)
15
16Disadvantages:
17
18 * graphic mode is slower than text mode...

21How to use it?

24Switching modes is done using lxfb.mode_option=<resolution>... boot
25parameter or using `fbset` program.

34XF68_FBDev should generally work fine, but it is non-accelerated.

37Configuration
38=============
39
40You can pass kernel command line options to lxfb with lxfb.<option>.
41For example, lxfb.mode_option=800x600@75.
42Accepted options:
43
44================ ==================================================
45mode_option specify the video mode. Of the form
46 <x>x<y>[-<bpp>][@<refresh>]
47vram size of video ram (normally auto-detected)
48vt_switch enable vt switching during suspend/resume. The vt
49 switch is slow, but harmless.
