TwinView on Ubuntu Edgy
 

Let me start by saying that I'm new to Linux. And that I've been trying for 3 days to get my monitors working the way I'd like with limited success.

Software : Ubuntu Edgy 6.10, Nvidia-GLX drivers, Beryl/Compiz With Emerald, TwinView Enabled.
Hardware : Nvidia GeForce 5500FX video card, Xerox XG-92d LCD monitor (DVI), LG Flatron L1930B LCD monitor (VGA)

Current Problems:

Resolution must be set at 2048x768 or the Xerox goes black and the LG displays half black/half desktop. I would like to be able to use a higher resolution, atleast on the Xerox monitor. Setting metamodes to values which are not equal (IE 1024x768; 2048x1024;) has had no effect.

I have two users. Logging in as the second user after restarting X disables the Xerox monitor. Logging in as the second user after i've been logged in as the first user without restarting X fixes this problem. Beryl does not work for the second user under any circumstances.

TwinView does not allow me to maximize a window in only one monitor. The window spans both. I'd like to fix this problem even if it means not being able to drag windows between monitors.

Files:

xorg.conf:

I have a couple of CRTs set to different resolutions, using separate screens - ie, no window dragging.

I found the easiest way to set it up was to use 'nvidia-settings'. On Ubuntu, I found the best way to run it was to open a Terminal, type 'sudo bash' and enter my password, then type 'nvidia-settings'.

You want the 'X Server Display Configuration' page. On the right hand side, there is a button labelled 'Configure...'. Press that, and select 'Seperate X screen'. Press OK. You can make other adjustments here, like the positioning of the screen, resolutions, etc. When you are finished, press the 'Save to X Configuration File' button. This will generate a new /etc/X11/xorg.conf file for you, backing up the previous file.

Hope that helps

I just tried this. It threw an error:

ERROR: NV-CONTROL extension not found on this Display.


ERROR: Unable to determine number of NVIDIA GPUs on ':0.0'.


ERROR: Unable to determine number of NVIDIA Frame Lock Devices on ':0.0'.

The Nvidia Control dialogue did come up, though. It did not, however, have the option you specified. I went to the synaptic package manager and tried to install the nvidia-settings module, but it wanted to uninstall the nvidia-glx module first.

Would uninstalling GLX cause me any issues?

Re: TwinView on Ubuntu Edgy
 

Ouch. Sounds like something isn't installed right. Probably a good idea to run `nvidia-bug-report.sh` and posting the nvidia-bug-report.log, as described in http://www.nvnews.net/vbulletin/showthread.php?t=46678

Did you install the Nvidia drivers from the Nvidia site, or from the Ubuntu repositories? I removed the Ubuntu version, and installed from the Nvidia site's files.

Re: TwinView on Ubuntu Edgy
 

Just generated a bug report. I used the ubuntu repository nvidia drivers. I'll try the download from the site now. Thank you for your help. I'll be posting back with the results.

Re: TwinView on Ubuntu Edgy
 

Eh, how does one go about shutting X off in Ubuntu Edgy that i might restart it with -- -verbose 5? All of my attempts have only resulted in X restarting and giving me a login screen. :(

Re: TwinView on Ubuntu Edgy
 

'sudo /etc/init.d/gdm stop' will shut down X for you. You can restart it by changing the 'stop' to 'start'.

Have a quick look at http://www.nvnews.net/vbulletin/showthread.php?t=79966 for some more tips ;-)

Re: TwinView on Ubuntu Edgy
 

I found that advice shortly after asking the question. I downloaded the drivers off of the nvidia site. Installed them, and now X crashes every time it tries to start.

The Nvidia installer originally threw errors about my needing a SDK/Development x.org package. Said it created the Kernel, and my xorg.config file. Then broke X. So i did "sudo apt-get install xorg-dev" and reinstalled the drivers. This time it didn't throw any errors, but still broke X. I'm on my windows partition right now, but i wrote down the errors X threw.

Failed to initialize nvidia kernel module.
Screens found but none have a usable configuration.
IO error 104(connection reset by peer) on x server ( 0.0 )

i think i may have to reinstall the repository drivers

Re: TwinView on Ubuntu Edgy
 

Have you got the linux-headers package installed?

Would be an idea to post the nvidia-installer.log

You might want to run nvidia-xconfig, and let that create a new xorg.conf for you. It will back up your previous one.

Re: TwinView on Ubuntu Edgy
 

linux-headers is installed.

Any idea how i might be able to get the installer log out of there? X is down so i cannot upload it with my web browser.

Already ran nvidia-xconfig. I allowed the installer to do that initially.


Also i reinstalled the repository driver and ran nvidia-xconfig, but the official driver installation rewrote the kernel, so x continues to break. Driver version differences.

So i guess my only hope is to get the install log up here and my Xorg.0.log, but how do i do that from the command line?

Re: TwinView on Ubuntu Edgy
 

Thank god for the command line FTP.

http://www.dirtay.com/Xorg.0.log

This is after reinstalling the nvidia website drivers. Allowing it to once again rewrite the kernel and xorg.conf files.

Re: TwinView on Ubuntu Edgy
 

Not sure about those checksum bits after "Validating previous installation". And having those references to version 8776 files, too.... May have to wait for someone a bit more knowledgeable than I, I'm afraid :(

At least your Xorg.0.log looks good ;-)
