Back several ubuntu versions ago I could resize the screen using Ctrl + Alt + - (For higher resolution) OR Ctrl + Alt + + (For lower resolution).
Now they do not seem to work. How can I add them again for resolution change.

I'm pretty sure this feature is gone since Bullet Proof X. However:

You can create short cuts (System → Preferences → Keyboard Shortcuts) to change your resolution:

  • Have a look at System → Preferences → Monitors to see your available modes, in my case there are four, from 640×480 up to my native resolution

  • You can now use xrandr -s 0 to xrandr -s 3 to change to one of them.

It's not exactly the same as the old +/– business, but it works rather well.

To add a short cut, in the Keyboard Shortcut settings, click add, choose a name, like 'First Resolution', a command like xrandr -s 0, and hit Apply. Then click the short cut cell, where it says Disabled and press, for example, Ctrl+Shift+Alt+0 (my preference).

Note: this works on any graphics card, not just NVidia's.

Actually i can not use System → Preferences → Monitors since it is recommended to use System → Administration → NVIDIA X Server settings. i wil try the rest you mention here and give it a go. – Luis Alvarado Jan 24 '11 at 17:22
Yes it works good. At least it gives me the default i like to use when something changes the resolution. Thank you. – Luis Alvarado Jan 24 '11 at 17:25
Cool! (I couldn't test it myself unfortunately). – Stefano Palazzo Jan 24 '11 at 20:20
