Changing display settings in Linux Ubuntu 9.1?

I am running Linux Ubuntu 9.1 and I am trying to to change the display sitting from 16bit to 32bit or vice versa. How would I do that?Changing display settings in Linux Ubuntu 9.1?
I may be wrong, but I think Ubuntu defaults to the highest the video card and drivers can support, so make sure you have updated drivers, or that you have the companies drivers (if they distribute any). Nvidia for example makes drivers available but you have to download them manually through system - administration - hardware drivers.



Other than that, it could be an X.org setting. Actually, it is, and if you want to edit it you do the following (AT YOUR OWN RISK -- this is the equivalent of editing the registry in Windows, and make sure that you edit the commands PRECISELY)



Press Alt and F2 at the same time. In the resulting box, enter the following command:



gksudo gedit /etc/X11/xorg.conf



It'll prompt you for your password. Enter it. Then, a text editor will pop up with the settings for X. Use the ';Find'; function in gedit Text Editor to find the term



SubSection ';Display';



Right beneath that, there should be a setting that says



Depth xx



Where xx is your current color bitdepth. 24 is the same as 32 bit color, because video cards only use 24 bits to store color information. The only valid numbers that can be put here are 8, 15, 16, or 24. If you want to switch to 16 bit color, replace xx with 16. Conversely, put 24 in xx if you want 32 bit color. Save the file, and close gedit. When you restart, the bitdepth will have changed.



Again, you do that at your own risk. Make sure you have those new drivers!Changing display settings in Linux Ubuntu 9.1?
