I often get the log-in prompt on the wrong monitor (VGA-0) in a dual monitor setup with a laptop panel (LVDS) and an external LCD TV (VGA-0). So I have a situation with a black screen on LVDS (i see the mouse cursor in the intersection between the monitors on the left edge of LVDS) and the log-in prompt displayed on VGA-0 which is also black (turned off). Is this related to lightdm and why not always use the primary monitor (LVDS) for login-prompt? xrandr: Screen 0: minimum 320 x 200, current 3320 x 1080, maximum 8192 x 8192 VGA-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 886mm x 498mm LVDS connected primary 1400x1050+1920+0 (normal left inverted right x axis y axis) 287mm x 215mm DVI-0 disconnected (normal left inverted right x axis y axis) lwhw: *-display description: VGA compatible controller product: RV515/M54 [Mobility Radeon X1400] vendor: Advanced Micro Devices, Inc.
