@Bryce: I get an error about no protocol specified / cannot connect to DISPLAY=:0 when trying to xrandr --auto from a console or from an ssh session.
Some more info on the garbling though: - if I set external (1920x1200) monitor to mirror the laptop (1920x1080) screen, I see the same garbling effect within a session. - using fglrx I can have 1920x1080 mirrored onto the external screen fine. so actually probably is not lightdm specific, but something with the ati drivers in oneiric (I've been able to mirror in natty/earlier). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/813566 Title: Greeter not displayed correctly on multi monitor setup Status in Light Display Manager: Triaged Status in Unity Greeter: Triaged Status in “lightdm” package in Ubuntu: Triaged Status in “unity-greeter” package in Ubuntu: Triaged Bug description: Upon booting with an external monitor (1920x1200 resolution) hooked up to my laptop (1920x1080 resolution), the external display mirrors the laptop display, but garbles the screen (see screenshot).
