Trying to configure 3 monitors on Ubuntu and Kali

It seems you have another Kubuntu install somewhere else? Would it be possible to copy the xorg.conf file over. Or you might live boot the version of Ubuntu you have installed and copy the stock xorg.conf file over. I don't know if it'll work but it might get you back to gui.

Tank you Mill J.

I'm following you. I started Ubuntu by live-cd, and in that way, the 3 monitors work perfectly. So I copy the "xrandr", that was perfectly configurated. I was unable to open the xorg.conf. (I don't know how to open the xorg using live-cd. It didn't work)

So, I made a copy of the xrandr, that works perfectly, but now that I'm without Ubuntu GUI acess, I don't know how to "write" the 'correct' xrandr.

By the way, please correct me if I'm wrong, but if I was able to have a terminal in GUI mode( I have the Kali), could I config the xrandr just by pasting it?

Now, how can I add the correct Ubuntu xrandr into the Kali terminal? Is it the correct way?

Try sudo nautilus or sudo nano /path to xorg.conf

I'm not completely sure what you mean by xrandr, is it a command? If it is than yes. Remember anything you do with xrandr only lasts until reboot. You'll have to run(automatically via script, etc) the command at start-up to make it persistent.

I'm also going to ask you the obvious, did you try logging in the broke Ubuntu without the extra monitors plugged in?

i'd rather recommend a broader search, e.g.:

dmesg | grep -iEC3 'error|fail'

ondoho, I did try the command that you suggest, nothing new.

Mill J, yes, I tried starting my Ubuntu with just "Screen0", the monitor that xrandr recognize. Also, nothing new.

I guess that what I need is just add at Kali "xrandr" command the configuration of the ubuntu live-cd xrandr config that I have copied. But I don't know how.

Could you post the xrandr command you copied?

Here it goes my ubuntu live-cd xrandr(I don't know why when I post, the text loses the spaces and diagram):

Ok so that is the output when you run xrandr on Ubuntu Live? It probably won't work to copy it over.

I don't have much experience with Debian(Kali).

Looking back over the thread I'm wondering if maybe you have some driver, modules, etc messed up.

In lxrandr there is a "use this display" checkbox for every monitor. Does it allow you to select and configure it? Obviously this won't work under the broken Ubuntu.

Mill J, why do you think that this output will not work?

The driver was a problem. When I was trying the Nvidia driver, nothing did work well and the other monitors were not recognized( at xrandr). So, I downloaded and installed the "Nouveau" driver, and then, with this new driver, the xrandr begin to recognize the others Monitors( although as "disconnected" status).

I cannot get arandr ou lxandr in Kali.

I was trying to use arandr at ubuntu, although the others monitors were recognized, I couldn't select them...They stay off, I was unable to "chose" and edit it.

This is the output of the command, not the command or settings itself.

The driver was a problem. When I was trying the Nvidia driver, nothing did work well and the other monitors were not recognized( at xrandr). So, I downloaded and installed the "Nouveau" driver, and then, with this new driver, the xrandr begin to recognize the others Monitors( although as "disconnected" status).

As I said earlier, I'm beginning to think it is a driver or kernel module problem. What I'd do next is live boot Ubuntu and see what drivers and modules are being used in the live version. Run synaptic and search for nvidia, etc.

Also check what modules are loaded with lsmod, more info here http://edoceo.com/howto/kernel-modules You could possibly have conflicting drivers and maybe you need to blacklist one.

I've never had to deal with nvidia cards since my cheap laptops have always had Radeon cards

I'm not been able tu run few commands at my Ubuntu. Synaptic is one of them. Apparently, the mirror that is configured in my installation is not working, and I will not try to modifiy it by now.

I think that, although the drivers or kernel modules could be messed up, the Xserver starts to show problems after I modify the xorg.conf. If the xrandr output can't be a solution, I guess that a good xorg.conf configuration would solve the problem, the broken Ubuntu as the 3 monitors question.

In my opinion, I think that what I need now would be a xorg.conf direction.

Highly possible. Let us know how it goes.

thanks for your sharing

Does anyone knows how to edit, transform that output of the live-cd "xrandr -q" (ubuntu output with tree monitors working) to a command "xrand - " outside the live-cd( that is, at a working installed Kali dist.)??

Tank you!
