Dual monitor with Dell D820 and docking station?
 

Hello

I am rather new to the board but have often found some very good hints on Linux while searching and reading the board ... so I decided to register in order place my own questions.

I have just searched for the topic but could not find a solution, so if I have missed an already written answer, please point me to that. Thanks so far.

The problem:
I have a Dell D820 laptop, using a docking station with external keyboard, mouse and LCD; everything is working fine, but as under Windoze I can't use LCD and "internal" display of laptop at the same time (e.g as a dual display setup).

The laptop is installed with OpenSuSE 10.2, latest patches applied. The laptop was installed while being off the docking station, but I do not think this will matter ... I have no option to switch on dual head setup within sax ...

Any suggestions?

Regards, Dietmar

Truthfully, I only have one... switch to a distro like mandriva or possibly ubuntu/kubuntu. Both of those have allowed me to use dual display setup with my dell laptop, c/dock II docking station, and whatever displays I choose to use.

Hi

Would be helpful if you could send or post your xorg.conf (or whatever your X11-config is named). I guess if have to double the monitor section (monitor[0] and monitor[1]) but I am not sure, neither about the graphics adapter section (must there a different bus id for every output?).

Thanks, Dietmar

I just completed installing Fedora 7 this morning. I'm running a d820, with docking station + two flatpanels . . . after much fooling around, I found this xorg.conf to be fully functional (last thing I need to do is figure out why sound only comes through the on board speakers and not the ones connected to my docking station - which is what I was searching for help with when I came across this post). I built this .conf based off of my previous FC6 .conf which was originally based on recommendations from the nvidia display configuration:

Hi

Thanks a lot.

I was working on this topic some hours and found some minor differences, between SuSE and Nvidia official configuration recommendation:

- SuSE uses nv driver not nvidia, seems to make a big difference
- sax2 does not recognize the card correctly and does not use nvidia (you have to use sax2 -r -m 0=nvidia to make sax2 using nvidia module and not nv)

Starting sax2 with nvidia module gives the oportunity to set up dual head display, but I got only a blank screen after an initial success :-(

I will give your configuration a try.

Thanks,

Stone

Same problem with dell c600 with docking station
 

hi,

I'm experiencing the exact same problem, only with a Dell C600 laptop with a docking station. I'm also running openSUSE 10.2. I did find this post:

http://linux-on-laptops.com/forum/showthread.php?t=139

but that seems to be only applicable to dell c600 laptops. When I connect my monitor directly to the VGA port, the same problem occurs (no video on monitor), however when I press fn-f8 it works. When the laptop is docked pressing fn-f8 doensn't resolve the issue :(

I hope some1 finds out how to fix this, it's really annoying...
