The quickest, least permanent, method is to pause booting and add the parameters from the grub boot screen. That first depends upon having a grub prompt....
So edit /etc/default/grub and append drm.debug=6 to GRUB_CMDLINE_LINUX_DEFAULT and run update-grub, then reboot. Once booted open a terminal and type 'dmesg > dmesg.txt' and then attach dmesg.txt here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1076389 Title: [12.10] On laptop start up with external monitor plugged in, only external monitor works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1076389/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
