After ubuntu upgrade, don’t forget to update your nvidia driver

Interestingly, ubuntu forgets the fact that you chose to use the proprietary Nvidia driver! After upgrade (of release) please go to settings and update the driver!

  • Please note There are two types of drivers that we can use: Open Source and Proprietary drivers. Open Source drivers have been created by the Linux community to function with certain video cards, and most video cards have an Open Source driver available. In addition, older hardware is typically better supported by Open Source drivers. In some cases, there is no proprietary driver for the graphics card (such as non-HD Radeons) and installing such a driver will only stop the Open Source driver from functioning correctly.

Editing grub2 for Ubuntu 10.2 to get over ctrl-alt-f1 (or ctrl alt f2-f6) issues in Ubuntu

This turns out to be much more painful than grub (v1) which had a simple menu.lst file. The new grub2 autoupdates based on kernel updates, which is great, but makes it a pain to edit basic configuration.

In my case I was attempting to change the default splash in an attempt to correct a framebuffer problem causing my ctrl-alt-f1 to not work. I went and updated the grub.cnf (equal to menu.lst file in grub1) file, but soon realized that it will be overwritten.

Reading further revealed that the trick is to update the /etc/default/grub file instead. Thereafter one has to run the update-grub command

So much to get ctrl-alt-f1 to get me a terminal!

(this applies to 10.2 atleast)

  • No /boot/grub/menu.lst. It has been replaced by /boot/grub/grub.cfg.

GRUB vs GRUB 2

  • The primary configuration file for changing menu display settings is /etc/default/grub.

  • No changes made in the configuration files will take effect until the update-grub command is also run.
