I did some research and the problem seems to be widespread. Using the workaround posted by Vangel Ajanovski in askubuntu (http://askubuntu.com/questions/142506/hybrid-graphics-on-ubuntu-12-04 -switching-to-discrete) I can switch to the discrete graphics, but when I do the laptop backlight turns off and I can't turn it on by any method I tried. It does work with an external HDMI display. I reported another bug report about this (#1163418)
I don't close this bug because this is only a workaround and is clearly a regression from Ubuntu 12.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1162526 Title: vgaswitcheroo - Can't switch to dedicated GPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1162526/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
