1 ============= 2 What is lxfb? 3 ============= 4 5 .. [This file is cloned from VesaFB/aty128fb] 6 7 8 This is a graphics framebuffer driver for AMD Geode LX based processors. 9 10 Advantages: 11 12 * No need to use AMD's VSA code (or other VESA emulation layer) in the 13 BIOS. 14 * It provides a nice large console (128 cols + 48 lines with 1024x768) 15 without using tiny, unreadable fonts. 16 * You can run XF68_FBDev on top of /dev/fb0 17 * Most important: boot logo :-) 18 19 Disadvantages: 20 21 * graphic mode is slower than text mode... 22 23 24 How to use it? 25 ============== 26 27 Switching modes is done using lxfb.mode_option=<resolution>... boot 28 parameter or using `fbset` program. 29 30 See Documentation/fb/modedb.rst for more information on modedb 31 resolutions. 32 33 34 X11 35 === 36 37 XF68_FBDev should generally work fine, but it is non-accelerated. 38 39 40 Configuration 41 ============= 42 43 You can pass kernel command line options to lxfb with lxfb.<option>. 44 For example, lxfb.mode_option=800x600@75. 45 Accepted options: 46 47 ================ ================================================== 48 mode_option specify the video mode. Of the form 49 <x>x<y>[-<bpp>][@<refresh>] 50 vram size of video ram (normally auto-detected) 51 vt_switch enable vt switching during suspend/resume. The vt 52 switch is slow, but harmless. 53 ================ ================================================== 54 55 Andres Salomon <dilinger@debian.org>
