Ubuntu Jaunty: ATI Radeon HD 2400 XT working in dual head (Catalyst 9.6)

1 – Compile and install driver:

sudo aptitude install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++5 dkms

sh ati-driver-installer-9-6-x86.x86_64.run --buildpkg Ubuntu/jaunty

# i386
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb

# AMD64
sudo dpkg -i xorg-driver-fglrx_*.deb fglrx-kernel-source_*.deb fglrx-amdcccle_*.deb

2 – Generate xorg.conf:

sudo aticonfig --initial=dual-head --screen-layout=right

sudo aticonfig --dtop=horizontal --overlay-on=1

sudo aticonfig --xinerama=on

Note: you can do “dpkg-reconfigure xserver-xorg” to reset you xorg.conf to default values.

3 – Bug workaround:

1. Login to a tty (ctrl+alt F1) and type sudo killall gdm.
2. Type sudo nano (or gedit, whichever you prefer) /etc/ati/amdpcsdb to edit the file. Go to the [AMDPCSROOT/SYSTEM/DDX] section and add:

   EnableRandR12=Sfalse.

3. Type this into a terminal, sudo nano (or gedit) /etc/X11/xorg.conf, to open the xorg.conf file.
4. Under the “Device” section add these options on separate lines:

   Option "EnableRandR12" "false"
   Option "DesktopSetup" "horizontal"

5. Now just restart your computer and it should be good to go.
