Public bug reported: I just completed the LTS upgrade of Xubuntu from 12.04 to 14.04. Upon rebooting, my notebook lost its dual display behavior of cloning the LCD to the external display.
Researching, I found no /etc/X11/xorg.conf file in place. Fortunately I make backups as I need different configuration settings based on my exact hardware set up configuration. I merely copied the correct template back to xorg.conf, IPL, and the display is now working as expected in this hardware configuration. Aparently, conf files from Xubuntu 12.04 were still correct as I did not make any changes. The xorg.conf file was mistakenly removed during the LTS upgrade process. ** Affects: nvidia-graphics-drivers-173 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-173 in Ubuntu. https://bugs.launchpad.net/bugs/1309927 Title: LTS upgrade from 12.04 to 14.04 deleted xorg.conf file completely To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-173/+bug/1309927/+subscriptions _______________________________________________ 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
