Actually, my problem is likely different than yours. Your issue is that the radeon card is still active, even if you are not using the driver.
I switch off the graphics card I'm not using with a startup script: # disable radeon card echo DIGD > /sys/kernel/debug/vgaswitcheroo/switch echo OFF > /sys/kernel/debug/vgaswitcheroo/switch # disable intel card echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch echo OFF > /sys/kernel/debug/vgaswitcheroo/switch -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. https://bugs.launchpad.net/bugs/675156 Title: Fan allways working when using xserver-xorg-ati _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
