If the screen lies then you are free to take it and beat some of the manufacturer staff with it until they fix it. I suggest somebody with a 120+ dpi screen burns a bag of Xorg CDs an beats some Xorg developer with it until they fix the X server since they don't seem to respond to logical reasoning. -- 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/521877 Title: [gm45] wrong screen size detected on X200s To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/521877/+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
