Here's some more information on the System Settings hang problem I posted earlier ( Ubuntu 16.04.2 hangs when open System Settings )

For the 1st time in the last half-dozen or so tries, it didn't hang indefinitely. I paid close attention to the clock and here is the information logged after the system hung for 11 seconds (22:02:46 - 22:02:57).

This is most likely due to svideo on your laptop.

You could try to disable svideo with kernel boot option like this:

video=SVIDEO-1:d

If you have grub you can edit the file /etc/default/grub and change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=SVIDEO-1:d"

Then execute:

$ update-grub
$ reboot

It's crashing in your video driver. Are you running a current version of Ubuntu with all of the updates? Have you installed any special video drivers?

You've got an antique BIOS. Update to version F.5A Rev. A asap, found at https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-dv6700-entertainment-notebook-pc-series/3632100

And with Intel processors, you should have intel-microcode installed... to make sure that you have the latest processor microcode...

In terminal...

sudo apt-get update
sudo apt-get install intel-microcode
  • It's 16.04.2 and I do keep it up to date -- no special video drivers -- I'll update the BIOS and install intel-microcode – Bob Bowden May 15 '17 at 13:30
  • @BobBowden do the BIOS and the intel-microcode and see if that helps. Also, does the problem occur if you log into the guest account? – heynnema May 15 '17 at 13:31
  • intel-microcode already the latest version. The BIOS update needs windows to run and it doesn't offer the option of creating a bootable USB drive if I run it on another box. I'll try the guest account – Bob Bowden May 15 '17 at 21:46
  • @username keeps getting filtered out of my comment – Bob Bowden May 15 '17 at 21:51
  • @BobBowden because I'm the author of the answer, it assumes that you want the comment to reach me, so it doesn't need/want the @ username. – heynnema May 15 '17 at 21:53
