Since the upgrade to Ubuntu 15.10 I am experiencing frequent freezes. This did happen on the same system before the upgrade, but not nearly as frequently. It seems to happen randomly. As of now I have no other computer that I can use to access my own during freezes by ssh and confirm that this is a graphic only issue / gather further info.
Before upgrading I had other issues on this laptop (laptop shutting down randomly after resuming from suspend) which are seemingly resolved by the upgrade.
The way that the screen freezes is most peculiar. I attach a picture of the screen for information.

Dear Christopher,
thank you for your reply. I have updated the BIOS with what appeared to be the newest version available from Dell.
I now get
> sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
A10

I did not experience any freeze for a short while (one full day, while my laptop was plugged into power). Today, while my laptop was running on battery power I experienced the first freeze since the BIOS upgrade.
It appears identical to what I used to have before upgrade (i.e. not only the laptop does not respond, to keyboard/trackpad, but the screen displays some strange pattern, cfr. the image attached to my first bug report).
