Instead if you notice overheating problems and/or you have an old Radeon HD graphic card, you can enable DPM by adding a boot parameter. In this case, and when your card supports it, you can change the fan speed manually. It might happen that you will need to go to root shell in recovery if some option or syntax error made your X server not loadable. It is possible, however, to enable KMS during the initramfs stage. have a peek here

To know which version of the Linux kernel you have installed, type this text in a terminal window: uname-r In Ubuntu 12.04 LTS with the 3.2.0-xx-generic Linux kernel, you might encounter Check the manpage of the Radeon driver for advanced options.

If reverting back to the original xorg.conf file does not work for whatever reason and you are stuck in the terminal, you can execute the following command: sudo dpkg-reconfigure -phigh xserver-xorg https://wiki.debian.org/ATIProprietary So I hope you got it!

Setting the radeon.dpm=1 kernel parameter will enable dpm. Unlike dynpm, the "dpm" method uses hardware on the GPU to dynamically change the clocks and voltage based on GPU load. Before you start modifying xorg.conf It is important to know what the capabilities of your hardware is before you start.
Install the xf86-video-ati package. The approach to getting Twin View or two monitors working in Ubuntu is much the same as getting a low resolution monitor working as described above. Normally, you should not get problems with KMS, if you got one then you probably already tried to configure your X or made some mistake in configuration. I believe aticonfig changes both xorg.conf and amdpcsdb as needed.
