I'm using Ubuntu 13.04 on the HP Pavilion dv7-6175us with AMD Radeon HD 6490M/Intel HD Graphics 3000 Switchable graphics. How can I make switchable graphics work on Ubuntu?

I've managed to install the fglrx driver and use the external graphics adapter. The problem is the new intel graphics driver.

Here's what I did:

  1. Ensure that you have the deb files for the current AMD driver (created with --buildpkg as described in previous posts)

  2. open a shell and download a previous version of the intel driver and it's dependencies:

    mkdir temp
cd temp
wget http://launchpadlibrarian.net/119461148/libudev0_175-0ubuntu13_i386.deb
wget http://launchpadlibrarian.net/111621162/xserver-xorg-video-intel_2.20.2-1ubuntu1_i386.deb

  3. remove the eventually installed fglrx and the installed intel drivers. When removing the intel driver let it remove both packages

    cd ..
sudo apt-get remove fglrx*
sudo apt-get remove xserver-xorg-video-intel

  4. install the older driver with its dependencies

    cd temp
sudo dpkg -i libudev*
sudo dpkg -i xserver-xorg-video-intel_2.20.2-1ubuntu1_i386.deb

  5. now install the fglrx packages (go to the folder containing the fglrx deb files). Warnings about defect link groups can be ignored (at least I did)

    cd <your folder with fglrx drivers>
sudo dpkg -i fglrx*.deb

  6. backup and remove the existing xorg.conf

    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

  7. create a new config file and switch to the external graphics adapter

    sudo aticonfig --px-dgpu
sudo aticonfig --initial -f

  8. reboot

That said, for 64-bit I had to pull the files from other sources than the ones listed in the post. Then in synaptic I locked the Intel drivers so they could not upgrade.

  • I find this doesn't work with the integrated card. You get tearing effects and no external display support. – labarna Apr 29 '13 at 14:12
  • I dont think theres a way to get both to work, i never use the intel gpu – Mark Apr 30 '13 at 07:37
