Did you take look at Xorg.0.log?
I don't have same Dell as your, but old Latitude D610 with Intel
graphic card, and I"ve install dedicated package for:
i A intel-gpu-tools                      - tools for debugging the
Intel graphics driver
i   libdrm-intel1                          - Userspace interface to
intel-specific kernel DRM services -- runtime
i   xserver-xorg-video-intel           - serveur X X.Org -- pilote
d'affichage Intel i8xx, i9xx
