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-X, which is subscribed to xserver-xorg-video-intel in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
