1 – Compile and install driver:
Source: http://wiki.cchtml.com/
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:
Source: http://jen3ral.wordpress.com/
- Login to a tty (ctrl+alt F1) and type sudo killall gdm.
- 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. - Type this into a terminal, sudo nano (or gedit) /etc/X11/xorg.conf, to open the xorg.conf file.
- Under the “Device” section add these options on separate lines:
Option "EnableRandR12" "false"
Option "DesktopSetup" "horizontal" - Now just restart your computer and it should be good to go.
Compiz still not working…
