Hi all,

    I am trying to use a USB VGA dongle on a XO with release v8.2. The
USB VGA dongle is a
generic USB to VGA adapter listed in the wiki page:

   However, I can not get it work by following the instruction in

   It is my setup:

yum install xorg-x11-drv-sisusb
cp sisusbvga.ko /lib/modules/`uname -r`/kernel/drivers/usb/
sudo depmod -a

  And then edit /etc/X11/xorg.conf

  However , if I follow the instruction from wiki , and just add
additional section of "Monitor" and "Device". It don't load sisusb
at all . Therefore, I have also added "Screen" section and modified
the ServerLayout. This time it could load sisusb driver, but still
not able to launch a X session on the USB VGA. Nothing was shown in
the monitor attached to the USB VGA. The log and
config file are attached in the email.

  Does anybody success to use USB VGA dongle on XO (v8.2)? And could
share the experience with me?
