@ -87,23 +87,38 @@ Special configuration for udlfb is usually unnecessary. There are a few
options, however.
From the command line, pass options to modprobe
modprobe udlfb defio=1 console=1
modprobe udlfb fb_defio=0 console=1 shadow=1
Or for permanent option, create file like /etc/modprobe.d/options with text
options udlfb defio=1 console=1
Or modify options on the fly at /sys/module/udlfb/parameters directory via
sudo nano fb_defio
change the parameter in place, and save the file.
Accepted options:
Unplug/replug USB device to apply with new settings
Or for permanent option, create file like /etc/modprobe.d/udlfb.conf with text
options udlfb fb_defio=0 console=1 shadow=1
Accepted boolean options:
fb_defio Make use of the fb_defio (CONFIG_FB_DEFERRED_IO) kernel
module to track changed areas of the framebuffer by page faults.
Standard fbdev applications that use mmap but that do not
report damage, may be able to work with this enabled.
Disabled by default because of overhead and other issues.
Standard fbdev applications that use mmap but that do not
report damage, should be able to work with this enabled.
Disable when running with X server that supports reporting
changed regions via ioctl, as this method is simpler,
more stable, and higher performance.
default: fb_defio=1
console Allow fbcon to attach to udlfb provided framebuffers. This
is disabled by default because fbcon will aggressively consume
the first framebuffer it finds, which isn't usually what the
user wants in the case of USB displays.
console Allow fbcon to attach to udlfb provided framebuffers.
Can be disabled if fbcon and other clients
(e.g. X with --shared-vt) are in conflict.
default: console=1
shadow Allocate a 2nd framebuffer to shadow what's currently across
the USB bus in device memory. If any pixels are unchanged,
do not transmit. Spends host memory to save USB transfers.
Enabled by default. Only disable on very low memory systems.
default: shadow=1

This is a kernel framebuffer driver for SMSC UFX USB devices.
Supports fbdev clients like xf86-video-fbdev, kdrive, fbi, and
mplayer -vo fbdev. Supports both UFX6000 (USB 2.0) and UFX7000
(USB 3.0) devices.
