Configuring VNC on Ubuntu 12.04 LTS Desktop Over SSH Before Logging In Locally

My goal was to log in to the Ubuntu 12.04 LTS Desktop desktop, over a SSH tunnel, using VNC, before anyone was logged into the desktop itself. This scenario occurs because although you may share your desktop over the built in “Desktop Sharing”, you may need to restart the system, and after rebooting you are left with a login screen desktop, but without a logged-in desktop to share.
The directions I followed are from this great post.

sudo /usr/bin/x11vnc -xkb -noxrecord -noxfixes -noxdamage -auth /var/run/lightdm/root/:0 -display :0 -passwd "yourpwhere" -forever -bg -o /var/log/x11vnc.log

Option notes: -xkb, help with keyboard modifiers. -noxrecord, don’t let the xserver do grabs, assume this helps with speed. -noxfixes, disable xfixes cursor shape mode, assume this helps with speed. -noxdamage, disable xdamage polling hints, this does help with speed, has to do with Ubuntu’s compiz. -auth, lightdm is the unity login manager. -display, the primary. -passwd not secure, tunnel over ssh also. -forever don’t quit after the first client disconnects. -bg go into background mode. -o redirect output here.

Bring a trailer

Barn finds, rally cars, and needles in the haystack…
We put together Bringatrailer.com because finding great vintage cars online has become too much of a hassle. There is no need to keep sifting through hundreds of hopeless projects or overpriced dealer inventories to find that one car you’ve been looking for. We pick the winners and save you the trouble… the best bargains, the best dream cars, and the best rarities.
We especially favor regularly driven real-world classics, and cars with well chosen period-correct modifications. We’ll usually skip the blue chip restorations and trailer queens unless they offer something amazing in aesthetic or rarity. Deep pockets can buy a big-dollar restoration but they can’t buy good taste or driving passion.

Engine Assembly Lube

When reassembling any of the internal parts of an engine I’d use
something like this
http://www.permatex.com/products/product-categories/lubricants/specialty-lubricants/permatex–ultra-slick–engine-assembly-lube-detail

rather than motor oil.
I’ve used motor oils in the past and never had any issues that I could
attribute to it. But consider what might happen while you’re
reassembling. You’ve got everything put back together and then your
kid gets sick, things get busy at your job, Aunt Judy dies, the dog
has puppies, and the neighborhood gets over run by Zulus.
By the time you’ve got things sorted out a month has gone by. And all
that oil you carefully applied to your parts has had time to slowly
drip it’s way down into the crank case.
Assembly lube stays put.
