Public bug reported:
Binary package hint: linux-image
Kernel 2.6.32-19 ignores the lid status which is bad if you use your
notebook with a docking station and an external display. Kernel
2.6.32-18 or older and the mainline kernels handle a closed laptop lid
like a disconnected LVDS display. Since kernel 2.6.32-19 lucid boots up
with a wrong diplay resolution because both displays a switched on even
if the lid is closed. The displays are mirrored and switched to 1152x864
instead of their native resolutions. This leads to a blurry and warped
GDM.
