Upgrade Linux Ubuntu Kernel graphics drivers to latest version

Upgrading these user-space driver components is as easy as running either

sudo apt-add-repository ppa:xorg-edgers/ppa
or
sudo apt-add-repository ppa:oibaf/graphics-drivers

for linking your system to either archive. That's then followed by running:

sudo apt-get update

to update the package meta-data and lastly:

sudo apt-get dist-upgrade

for upgrading all of your operating system's packages.
After that, reboot, and if all goes well you'll be running the very latest Linux graphics drivers.

Enable SNMP on ESX server.

First of all you will need a vmware CLI.

Set Trap destination:

Set snmp get port:
vicfg-snmp.pl --server --username root --password -p

 Enable deamon:
 vicfg-snmp.pl --server --username root --password --enable

That's it
