I have a Probook 4530s and just installed Ubuntu a week ago. This laptop has both an ATI 6490m graphics chipset and integrated Intel HD graphics.

The ATI graphics seem to overheat the system, resulting in freezes. How can I disable the ATI and use the integrated Intel HD 3000 instead?

I don't need the ATI in for Ubuntu, just for gaming in Windows 7. BIOS is no option because I don't want to enable and disable the graphic all the time I'm switching between Windows and Ubuntu.

uninstall fglrx if you have installed it and then follow this answer on hybrid graphics

The overheating problem you are facing is most probably coming from the default that both graphic cards are running. Turn one of and the overheating should be history.

  • what about the way of blacklisting the ATI gpu? i read about that, but didn't understand that right... – Marc Apr 02 '13 at 00:28
  • I think you have something in mind like echo "blacklist radeon" | sudo tee -a /etc/modprobe.d/blacklist.conf. This is something you do if you face problems with my posted solution. Also you then would have to add modprobe radeon echo OFF > /sys/kernel/debug/vgaswitcheroo/switch in /etc/rc.local. What this would do is deactivate the AMD ATI card. This is then done by not loading the radeon module and initialising it afterwards on boot. vga_switcheroo needs radeon to be enabled, therefore this extra step. It ensures that radeon is loaded second and will therefore be turned off. – onse Apr 02 '13 at 01:22
  • after multiple system lacks, freezes, starts without unity, running on low graphics and other failures, this is what worked for me. http://planetoss.com/articles/how-to-disable-the-discrete-amd-graphics-card-in-linux/ – Marc Apr 02 '13 at 18:11
  • ok, just half an hour later... not that lucky anymore. recived multiple apport messages caused by hanging GPU... Executable path: /usr/share/apport/apport-gpu-error-intel.py

    even the apport popups have graphicbugs, some of them appear without showing any thing, they just look like a Pill with a black top and a white bottom. any suggestions? maybe it could be the Intel driver :D, maybe...

  • have a look at http://askubuntu.com/questions/143102 also what GPU are you now running? Discrete or the Intel one? – onse Apr 02 '13 at 20:16
  • Intel is running right now and producing these lacks, and graphicbugs... would an driver update solve this problem?

    ~$ cat /sys/kernel/debug/vgaswitcheroo/switch 0:DIS: :Off:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0

  • I can't promise anything, but you could try ppa:ubuntu-x-swat/x-updatesor even ppa:xorg-edgers/ppa. Just be sure that you know what you are doing. This is bleeding edge. – onse Apr 02 '13 at 20:42
  • commands not found, tried it with sudo, same here... – Marc Apr 02 '13 at 20:47
  • these are user repositories. Obviously you don't know anything about it so I highly recommend reading on this topic: http://askubuntu.com/questions/4983 Essentially it breaks down to you adding them with sudo add-apt-repository. After that you - in this case - sudo apt-get update && sudo apt-get dist-upgrade. Again I want to stress that you should not do that if you don't know what you are doing! – onse Apr 03 '13 at 12:01
