Ubuntu unable to change resolution to desired setting
Ubuntu is a PITA (Pain in the Ass) when it comes to graphic cards…. wow, i have wasted soooooo much time fixing and helping others fix graphic problems with Ubuntu…. They just havent figured out the video thing yet…. anyway….here are some fixes regarding graphics in Ubuntu….
You know, when you try to set a resolution for your kicking video card… and it only displays 800×400 and all your configuration buttons are off the screen, so you have to guess what button is highlighted….yeah thats the problem!
For the first example i will use an Nvidia GeForce 7800GT PCIexpress
Goto Nvidia, download most current driver
Boot into recovery mode
sh NVIDIA blah blah blah
overide all stupid warnings
ok to install open GL
exit and reboot
all is as it should be

SSH OpenSSH on ubuntu – very nice link to SSH information too
OpenSSH provides secure remote access to your computer, allowing you to run command line and graphical programs, transfer files, and use a “port forwarding” capability to securely tunnel other protocols through firewalls and untrusted networks.
SSH replaces older, insecure programs like telnet, rlogin, and FTP. These older applications transmit passwords across the Internet without encryption, meaning the password could easily be stolen.
Installing the SSH Server
If you want to securely connect to your machine from a remote computer, even a computer running another operating system like Mac OS or Windows, then you need to install the openssh-server package from the main repository. Installing software is discussed in InstallingSoftware.
