My question is:
I am using VMware 7.1 and enable vesafb 800×600 ARGB 32
for /dev/fb0 .
Here is my vesafb fb0 setting
http://www.wretch.cc/blog/fatalfeel/655235

If I need /dev/fb1 for directfb using,do I need to buy an USB External VGA Card?

Does any other way to enable /dev/fb1 ?

Please email me fatalfeel@hotmail.com

The make check with Libldo works just fine.
But I found out that I am missing the Framebuffer device files /dev/fb*.

The only change that happens when I connect the device are the usb device files.
/dev/usbdev*.*_ep00 01 02

$ lsusb
BUS *** Device ***: ID 17e9:01ac Newnham Research

$fbset -i
Frame buffer device information
Name : BUFFALO GX-DVI_

When I tried adding framebuffer support in grub menu.lst as stated in https://wiki.ubuntu.com/FrameBuffer
The Xwindows fails to detect all the display devices & starts in low graphics mode.

Also from that thread
http://ubuntuforums.org/showthread.php?t=333657
I tried to enable the Framebuffer support in xorg.conf
when asked during running
$ sudo dpkg-reconfigure xserver-xorg

I even tried the old Gutsy Framebuffer HOWTO
http://ubuntuforums.org/showthread.php?t=652038

But all the same result, no device files & X failure into low graphics.

Any hints will be much appreciated.

TIA

I have DisplayLink based Lilliput UM-70 external 7″ USB monitor. Your post helped me to get it working in Ubuntu 10.04. But it did not involve any source compilation of kernel or modules. But I had to download and use a mouse-wrapscreen utility to get mouse move over both the screens. And also I had removed BusID line from my xorg.conf to get my primary laptop screen to work. Here is more details:

Separately, I’m focusing more now on small modifications to the standard fbdev X server to make it work with udlfb, in the hopes of submitting those patches back and getting rid of the need for a separate X server for DisplayLink devices. More on that at http://plugable.com/2010/05/21/linux-support-for-higher-res-monitors-on-lower-res-displaylink-devices

It Works fine for me as a 3 screen setup. Displaylink at 1680×1050 as one X screen, and my ati card with two outputs.

Sadly displaylink crashes X in 24 bit colour mode and ati won’t do 16 bit mode so I can’t have xinerama; so I have two have two desktops – one for displaylink and one for ati.

I attach my xorg.conf in case it helps anyone else:

1. Boot up
2. insert USB displaylink
3. echo -n 1 | sudo tee /sys/bus/usb/devices/1-1.3/bConfigurationValue
4. sudo restart gdm
