Misconfigured Graphics Server

Your Graphics server may be misconfigured if you have the folloing symptoms

  • you are not getting any graphics, just a text log in screen
  • you are not getting the right resolution for your screen

This may happen if you've installed/upgraded the kernel or changed your graphics card.

You will need to log in in text mode. If you are not at a text login press Ctrl+Alt+F1. Log in and type

sudo dpkg-reconfigure xserver-xorg

Follow the questions, most thing are automatically detected

note: you may need to know how much memerory you graphics card has, which is mb x 1024. You may also need the horisontal sync and vertical refresh of your dispay.

To restart the graphics server type

sudo /etc/init.d/gdm restart

or, if you are using kubuntu

sudo /etc/init.d/kdm restart

For the kernel update you must also install restricted-modules hiting escape at boot will allow you to boot into previous kernel and install them with synaptic.
