Dual monitor


Hello,

I'd like to use a second monitor with my notebook but don't find a proper solution.

If I start up with my second monitor contected I see the desktop on both monitors.

My notebook:
compaq nx9020
82852/855GM Integrated Graphics Device [8086:3582]
Zenwalk
Kernal 2.6.25.4


Thank you!

Regards, Clemens

There must be a setting to disable one of the screens. Find the configuration program where you e.g. set up resolution and all the other X-related settings, and try to disable the laptop screen. I

Hi,

I don't want to disable one sceen.

I'd like to use both at the same time but the second monitor should show an extended desktop.

You might have problems with refresh rate - it must be the same on both displays to make it work. Ideally the size/resolution should be the same as well. A few days ago I did a similar thing with 2 different monitors (the same refresh rate / different resolution). It did not pick up the second monitor automatically so I went to nvidia-settings (what driver are you using?) and just enabled the second display (in TwinView), adjusted the resolution for both displays) and it just worked. The only problem I've got is that I need to do it every time I reboot the computer.

You should look into xrandr
There is a package named lxrand, which is part of the lxde project, that is supposed to provide a gui for it, but I have never tried it. Gnome 2.24 in the snapshot repositories includes a tool for setting up multiple monitors too.

Where do I find the used driver?

You've got an integrated intel gfx card. I've never used it so I don't know if the card and its driver support dual head.

Here's a tutorial for xandr:

Alternatively you might want to try xinerama although it is no longer under active development:

Smile You could try Ubuntu 8.10.. it has dual monitor functionality built in

You could try Ubuntu 8.10.. it has dual monitor functionality built in.

Dual Monitor configuration is now working for me, natively, on hp Compaq nc6320 notebook.

System > Preferences > Screen Resolution

I then unchecked "Mirror Screens"(Monitor Resolution Settings dialog), moved around the little pictures of the monitors to match my configuration, set the screen resolution for my externally attached monitor to 1280x1024, clicked apply. I then had to enter my password for software to install, and then again to save the settings. I was then instructed to logout and back in.. and Voila! Extended monitor.

The Ubuntu team ROCKS!!!!
GNU/Linux Rocks!!!

@Shannon_VanWagner
Nice try trolling about another distribution!
As you may have noticed this is the Zenwalk Linux section though.

And FYI, what you're raving about is not an ubuntu feature, but a gnome feature and every distribution that includes gnome 2.24 has it, Zenwalk included. Feel free to change your statement anytime you like to:

The Gnome team ROCKS!!!!

Smile Woops... sorry... didn't mean to troll on you there

gapan, Zenwalk, et. al.

Woops.... sorry about that... I failed to see right in front of me that this is the Zenwalk forum.

No offense intended fellow GNU/Lxers.

As for the dual monitor working in Ubuntu 8.10, I didn't mean to give credit the Ubuntu team for making the software for the dual-monitor setup in terms of owning that functionality for GNU/Linux. Rather, I just wanted to mention that they had just made it easier for users of Ubuntu 8.04 who have upgraded to 8.10 to use the dual-monitor feature. Although I would like to see that more easily-installable GNU/Linux distros would consider making this dual-monitor thing easier for end users anyway.

I truly do root for ALL GNU/Linux, not just Ubuntu. I am, in fact, a BIG supporter of GNU/Linux in any form.

Once again, sorry for posting in the wrong area.

I'll wear my deserved troll sign for the day (good day for it anyway).

Have a good weekend!

GO GNU/LINUX!!!!

Configuration Problem with xorg.conf

This sounds like a configuration problem with X. I'm not all that familiar with the commands of the xorg.conf file, but that is what X looks for when working with just about everything. Be very careful with this file as if you mess it up you will have to vi into it in order to reconfigure X. Toward the bottom part of the file you will observe a section titled Screen0, if configure correctly you should also have a section titled Screen1. With just one section both monitors will display the same display (kind of like connecting a y connector from two video cards to one monitor). As far as the specs on your monitor you will have to do some research, but they should be close to screen0.

Hope that helps.
Todd

P.S. Make sure that you back-up this file before saving or modifying. Linux is supposed to automatically back this file up, but sometimes i've seen that the backup is rewritten when several changes/saves have been made. So store the extra backup with an extension that will help you to find it and keep linux from overwriting.

Thx, this sounds a bit complicated and difficlute.

Isn't there an easier solution?
If I take my notebook to another place and conect another monitor/beamer, it's not comfortable mucking around for hours to get the new screen running.

Isn't there any GUI or terminal based program that manages my problem?

Thx!

Clemens

garand pointed you to what seems to be a great add-on to accomplish what you are trying to do. Why not check it out? The site even tells you how to configure your laptop for dual monitor support.

If you have tried that and it's a no go then just try my suggestion, it does not take long to open up xorg.conf and change the settings you need, and if things go wrong, just revert back using the command prompt.

Unfortunately, with as broad as the linux community is things are sometimes hard to find. Also, please remember that Linux is still no where near as user friendly as Windows, but of course there is only one Microsoft and they have been around for what over 32 years now? They do have a leg up in that department.

If I can help, and I do believe that goes for the rest of the community, which is something that really can not be said of the MS community, we are here willing and able.
