What is gxfb?
This is a graphics framebuffer driver for AMD Geode GX2 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 gxfb.mode_option=
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 gxfb with gxfb.
mode_option - specify the video mode. Of the form
vram - size of video ram (normally auto-detected)
vt_switch - enable vt switching during suspend/resume. The vt
switch is slow, but harmless.
