I am new to Ubuntu but at the same time shocked with the fact that a lot of work is needed to get my computer setup to get it connected to various devices. This is trivial in Windows 7 which really made my think why shall I move in Ubuntu. I still like Ubuntu and hope these problems can be solved more easily.

My problem at the moment is connecting two monitors to my Laptop (Toshiba Tecra M10). I am using a DVI-VGA USB (Winstar) adapter to do this job which works beautifully in Windows 7. I have been fiddling with Ubuntu 12.10 for a week now in order to get this dual monitor working. I also tried to setup Xorg.conf few times but this caused Ubuntu failing and had to Re-install Ubuntu for the third time. It is interesting that changes in Xorg.conf is very damaging and once you loose booting it is very difficult to go back even with the recovery mode which I found very difficult and useless in many ways. If anyone can have any suggestion, then I will be very grateful.

  • Chiptype = Mobile Intel(R) series Express
  • Adapter = Mobile intel(R) GMA 4500MHD
  • Monitor 1 = BenQ E2420HD (resolution = 1920x1080; orientation = landscape; refresh =60; color 32 bit )
  • Monitor 2= BenQ G2420HD (resolution = 1080x1920; orientation = portrait; refresh= 60; color 32 bit)

    Monitor1 and the laptop monitor are extended

Here is what I did but did not work and actually damaged the Ubuntu setup.

1- Install Miscellaneous Mesa GL utilities (help detecting the graphics card)

2- Update kernel and its headers Install linux source (sudo apt-get install linux-source) and headers (sudo apt-get install linux-headers-generic). Not really sure if this was necessary.

3- Download https://launchpad.net/ubuntu/+archive/primary/+files/xserver-xorg-video-displaylink_0.3-0ubuntu10_i386.deb this would not download as it is dependent on an the old xorg-video-abi-11. Could not download this component so I tried the next

4-

sudo apt-get update
sudo apt-get install libusb-dev xorg-dev build-essential
cd ~/Desktop
wget http://projects.unbit.it/downloads/udlfb-0.2.3_and_xf86-video-displaylink-0.3.tar.gz
tar xzvf udlfb-0.2.3_and_xf86-video-displaylink-0.3.tar.gz
cd udlfb
make && sudo make install && sudo depmod -a
cd ../xf86-video-displaylink
./configure && make && sudo make install
gksudo gedit /etc/X11/xorg.conf

OK here I got many errors when trying to install displaylink. The main thing is that displaylink_drv.so could not be copied to /usr/lib/xorg/modules/drivers.

So what I've done is to extract xserver-xorg-video-displaylink_0.3-0ubuntu10_i386.deb and then copy displaylink_drv.so to both /usr/lib/xorg/modules/drivers and /usr/local/lib/xorg/modules/drivers.

OK up to here nothing has changed even after re-boot.

So, I installed install Video decode & encode driver for Intel G45 chipsets and Intel HD Graphics for Intel Core processor family.

sudo add-apt-repository ppa:glasen/intel-driver
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get upgrade

re-boot

Noticed a flicking in the power light Monitor 2 (not green color yet). So decided to play with Xorg.conf. Here is Xorg.conf content:

Section "ServerLayout"

        Modes       "1920x1080"
    EndSubsection
EndSection

Section "Screen"
    Identifier "Screen1"
    Device     "Benq G2420HD"
    Monitor    "Monitor1"
    DefaultDepth 32
    Subsection "Display"
        Depth      32
        Modes       "1080x1920"
    EndSubsection
EndSection

Section "DRI"
    Mode 0666
EndSection

This did not work and got the laptop and screen 1 blank while monitor 2 was displaying the boot screen with Ubuntu logo in the center.
