How do i set up Dual Monitors? w/ 2 cubes

[redonwhite]

Hello, i have ubuntu 8.04, compiz fusion, awn. I have one 22inch wide screen monitor, 1680x1050 and a 17inch monitor 1024x1068. Nvidia 8800 drivers installed and enabled. I was messing around in Nvidia settings and was able to Stretch the screen to the second monitor. But my goal is to have TWO cubes. One on each monitor. Not mimicking each other but having there own separate desktop space. Can this be done? Thank you ahead of time for your help.

It can be done if you setup Xorg with two completely independent screens. This requires two separate device and screen sections in your xorg.conf file. While I'm not 100% sure, I believe this can be done via nvidia-settings.

It can be done in nvidia-settings, but note that, you cannot move windows from one monitor to the other using that setup.

Also you need to run compiz with the --only-current-screen option

Thank you for the replys guys. Im pretty new to Nvidia-Settings. Could you walk me through setting that up Some-Guy? Im still a linux newbie =). 4 Days in! hehe.

[some-guy]

open a terminal(Applications >> Accessories >> Terminal) and run 'sudo nvidia-settings'
Go to 'X Server Display Configuration'
Set the resolution to the right amount, and click 'Configure', set it to a seperate X screen, then do the same with the other monitor

Click 'Save to X configuration file'

Logout, then Ctrl+Alt+Backspace
After you log back in, run 'compiz --replace --only-current-screen ccp' on each screen

Some-Guy i bow down to you. Thank you thank you. ...i followed everything except for the run compiz part. How do i go about setting that up? the current setting in compiz you were explaing. Again Sorry for the Newb questions. and THANK YOU again.

open a terminal on each screen, and run
'compiz --replace --only-current-screen ccp'

[redonwhite]

K thank you Some-Guy, youve been ALOT of help. .....I noticed my Drop down menus and when launching apps that there is a puase. It seems slower on my main screen. Is this normal? Do you think after a reboot it may quick back up? The second screen seems to be responding normally though when dropping down menus and what not.

[redonwhite]

The slow down seems to be caused by AWN. I typed the compiz--current settings command you told me in the terminal and nothing happened. so just typed compiz and then my screen flickered and AWN disapeared and things got fast again. I then typed compiz on the second terminal on monitor number two and AWN returned and things slowed down again. hmmmm any ideas?

[some-guy]

try running
compiz --only-current-screen --loose-binding

--loose-binding help a LOT on nvidia cards

[redonwhite]

I had to reload my back up file. The first screen was reallyyyy slow. Hitting in the 90s percent cpu usage when scrolling through menus. Oh well maybe ill give dual screens a shot some other time. I thought my PC would be able to take it.

You can always set up twinview, but you won't have two separate cubes, however, there are advantages, you only have one instance of compiz running, you only have 1 xscreen, and you can move a window from one screen to the other :D

Very true. Well it was fun messing around with it =). Thanks again for your help buddy. Have a great day.

It _should_ work with only one instance of compiz (if you have 2 XScreens)
