Okay I was finally able to add more screen resolutions to my System>Preferences>Display. It turns out when I was trying to reconfigure xorg.conf, I had no access. Thanks to Dave Domingo for telling me that I need to have “root access”. So does sudo mean execute as root?
Step 1: Go to System>Administration>User and Groups
Step 2: Select “root” and click [Unlock]
Step 3: Enter your password and click [Authenticate]
Okay, now once you have root access do the ff:
Step 1: Go to Applications>Accessories>Terminal
Step 2: Type sudo gedit /etc/X11/xorg.conf
Step 3: Look for the Section “Screen”, you will see something like this:
Step 4: Make it look something like this (added lines in green)
Step 5: Save and Close. Exit Terminal.
Step 6: Restart Ubuntu and Login
Step 7: Goto Systems>Preferences>Display and you should be able to select the added modes in the “Resolutions”
Next time, I’ll try to add a Guest Account.
