1 [This file is cloned from VesaFB/aty128fb] 2 3 What is lxfb? 4 ================= 5 6 This is a graphics framebuffer driver for AMD Geode LX based processors. 7 8 Advantages: 9 10 * No need to use AMD's VSA code (or other VESA emulation layer) in the 11 BIOS. 12 * It provides a nice large console (128 cols + 48 lines with 1024x768) 13 without using tiny, unreadable fonts. 14 * You can run XF68_FBDev on top of /dev/fb0 15 * Most important: boot logo :-) 16 17 Disadvantages: 18 19 * graphic mode is slower than text mode... 20 21 22 How to use it? 23 ============== 24 25 Switching modes is done using lxfb.mode_option=<resolution>... boot 26 parameter or using `fbset' program. 27 28 See Documentation/fb/modedb.txt for more information on modedb 29 resolutions. 30 31 32 X11 33 === 34 35 XF68_FBDev should generally work fine, but it is non-accelerated. 36 37 38 Configuration 39 ============= 40 41 You can pass kernel command line options to lxfb with lxfb.<option>. 42 For example, lxfb.mode_option=800x600@75. 43 Accepted options: 44 45 mode_option - specify the video mode. Of the form 46 <x>x<y>[-<bpp>][@<refresh>] 47 vram - size of video ram (normally auto-detected) 48 vt_switch - enable vt switching during suspend/resume. The vt 49 switch is slow, but harmless. 50 51 -- 52 Andres Salomon <dilinger@debian.org>
