[This file is cloned from VesaFB/aty128fb] 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.txt for more information on modedb resolutions. X11 === 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. |
