What is your Dell's graphic's subsystem? On some Intel based graphics
systems, I found that I needed to add "nomodeset" to the kernel parameters
in /etc/default/grub and then add nomodeset in the line that has
GRUB_CMDLINE_LINUX_DEFAULT and then run sudo update-grub. See this page for
details:

HTH,
