Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

yes you are right!! i am so stupid, i forgot it didnt work, i just finished trying it and i remember now it crashes on nvidia and nouveau drivers,



i tried your 2 new files, but they had problems,


1st file
- the same problem happened as the other files, except this time, the icons were on a different monitor,

2nd file
- i could move freely between the all, but when i expanded firefox it went to all monitors, and then when i move the desktop icons, it froze,

Is the primary monitor correct, the one with the menu and panel?

I wonder if you create a desktop launcher by right clicking on the desktop and using the command to open Firefox (firefox %u), if it can be moved to another monitor.

You can also test using different Window Managers in Desktop Settings. The default is Xfwm4+Compositing.

Try testing these last two xorg.conf files:

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

it works!!!!!!!!!!!! but i did find 1 bug,

Your last file didn't work at the start, but then i did what you told me, i went into desktop settings and i changed the theme, i forget what setting i had it to,

but i changed it to "Megacity" and now it works.

i can maximize, i move firefox to all screens, and i can move all my desktop icons to any screen!


The bug i did find is, that when i watch a movie or video on vlc player, the video plays really slow, and my computer starts to become super slow, everything is lagging, so i cant watch videos or movies,
which isnt a big deal since i dont often download movies anymore, youtube works perfect, no problems with youtube


i had to switch my screens around in the nvdia settings, they were not beside each other the way i wanted to, everything works except the video.


here is my final file

For VLC video problems, open VLC and go to Tools > Preferences > Video and first try disabling Accelerated video output(Overlay). Then try another selection, such as X11 and XVideo. The default setting may be Automatic. For some selections, you may have to disable the Accelerated video output (Overlay) too.

Also go to Tools > Preferences > Input and Codecs. The setting next to Hardware-accelerated decoding is set to Automatic. You can test other selections.

You can also install mplayer. I use it play that occasional video file that VLC can't play:

Code: Select all

sudo apt install mplayer

Starting from the left side, what monitor is the primary one, the one with the menu and panel?

My instructions for VLC may have been confusing. First try disabling Accelerated video output. If that doesn't help, then re-enable it and then try one of the other selections.

Wow! I just looked over the reconfigured xorg.conf file in detail and it may be the longest I've ever seen. It's enough to frighten anyone trying to learn how to configure one of these files, but it had very valuble info for me. There is one added line that is a little confusing. Where did DFP-7 come from: Option "nvidiaXineramaInfoOrder" "DFP-7"
The Xorg.0.log file would probably have to be examined to determine that.

This last part is optional, as I know many users like to leave working configurations alone. However, the xorg.conf file has some redundency and unneeded lines. A more compact file would make it easier to read and understand, and future editing easier, if it is needed after you install your sixth monitor. If you want to do this, then continue reading. You already have an xorg.conf.old file, so it can be removed with this command:

Code: Select all

sudo rm /etc/X11/xorg.conf
Then rename the existing xorg.conf file to xorg.conf.old:

Code: Select all

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
Then create a new edited and compacted file by adding these lines:

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

hello sir!! sorry i was not able to test it fast, but i had some exams, i am ready to test again!!

i have just finished testing it and i can tell you that the LAST file you sent me is working! working better than all the other ones before

the one that was working before, it had a glitch, i was not able to delete the workspaces, when you first install mint, it comes with 4 default workspaces, i deleted 2 because 2 is all i need, but when i tried your file, the 4 workspaces came back! and i was not able to delete them, it was stuck on 4


but the last file you sent me, is working, no glitch, there is a problem with an application called "Open Bazaar" when i try to move it, it flickers aways, so i have to keep it maximized at all times, but i dont use that application often,

but yes! the last file is working! on all 5 monitors!


how can i add another monitor? i added another monitor tonight, and its working fine, but 2 monitors when i expanded expanded on 2 monitors,

it seems the 2 orange monitors are acting as one when i maximize
screen.png
but i can move firefox and any application from all 6 monitors!! YAY!

here is the final xorg file

Those two monitors need to have separated Monitor, Device and Screen sections in the xorg.conf file.

Rename the existing xorg.conf file and create a new one with these lines:

If that doesn't work correctly, then remove the line Screen 5 from the fifth Device section first, and if needed, line Screen 4 from the fourth Device section. If that doesn't work, then post the Xorg.0.log file.

If everything works correctly, then post the output of xrandr and the Xorg.0.log file.

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

The first file didn't work correctly, both of the 2 monitors were black, the other 4 monitors were fine

When i removed the Screen 5 line, both monitors were black, the other 4 monitors were fine
When i removed the Screen 4 line, 1 monitor was black and the other one was working, except my mouse was not able to go into it, the other 4 monitors were fine

I'm not sure if i removed the line correctly, here's how it looks

Re: 2 graphic cards, multiple monitors possible?

Post by roblm »

Open the Nvidia Settings utility. Check that the 6 displays are positioned correctly. Then click Save to X Configuration File. Log out and back in. If everything works correctly, then post the xorg.conf and Xorg.0.log files.

Also, which monitor is the primary one?


EDITED: 5-14-17

I found what I think was the error. The monitors for Screen4 and 5 need to be switched. Try using the xorg.conf file below:

If that doesn't work correctly, then remove the line Screen 5 from the fifth Device section first, and then line Screen 4 from the fourth Device section if needed.

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

it works!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


i tried your last code, but the 2 monitors were black, so i went into the nvidia settings and enabled them, then i logged in and out and your code is working!

The primary monitor is X screen 2, DFP-5 on GPU-0


i wasn't sure what you meant about Xorg.0.log because i couldn't find it, but i think i found it, it was in the /var/log folder


Is it safe to post that file here? there seems to be alot of strange numbers inside that file pertaining to my computer

Code: Select all

Yes, that's the correct location of the file and it's safe to post it. I still would like to see it because it has valuable info used to configure your complex setup, especially the nvidiaXineramaInfoOrder lines. Use this command to open it:

Code: Select all

xed /var/log/Xorg.0.log
Press Ctrl+A to select the entire file contents. Right click on the screen and select “Copy”. Don't save it to a file. Open the Mint Forum reply window and select “Code” in the menu. Press Ctrl+V to paste the lines between the two code words.

If you have problems posting that long file, then install pastebinit:

Code: Select all

sudo apt install pastebinit
Then use this command to upload the file to pastebin.com:

Code: Select all

pastebinit /var/log/Xorg.0.log
Post the URL link that displays in the Terminal window.

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

xinerama is really slow compared to not using it,

even my dolphin emulator lags when using xinerama, but if i disable xinerama, it doesn't lag

why is xinerama slow compared to not using it,

do you think it's because i have to different type of video cards?

would xinerama performance improve if i had 2 gtx 970's,
what if i sli both those cards,

would it be faster then of what i currently have now, 1 gtx 970 and 1 gtx 640

i really wish i had a way to test but none of my friends have a gtx 970, and i looked online but they are all around 300, ive seen someone for 150 but they go fast, i would buy one for 150


any idea?

Re: 2 graphic cards, multiple monitors possible?

Post by minty_22 »

i just realized that if i sli 2 gtx 970s, i wouldn't be able to use 8 monitors, because when you sli 2 video cards it turns it into 1 video card, so i would only be able to use 4 monitors,


so the only questions are,
1. i wonder if 2 video cards of the same type would make a different if i used them in xinerama,
2. i wonder if i could move applications throughout all monitors without using xinerama if i had 2 of the same video cards, although i doubt it because they are on different gpu's (gpu-0, gpu-1)

well i ended up buying a second gt640.. and the results are in....

it doesn't work as i expected!

so, 2 of the same model video cards act the same as two different model video cards in linux

so, as soon i got the video card, i installed it along side my gt 640, so i had 2 gt 640's

1. i tried using the nouveau drivers, and it worked! i could move apps from monitor to monitor, but only about 2 or 4 monitors, after that it was slowing down, and i couldn't even enable some monitors,
theres way too many glitches using the nouveau drivers using the same mode video cards, and with different video cards it was even worse, i couldn;t even get the second video cards to work,

2. i tried nvidia drivers without xinerama, and i could move apps from monitor to monitor as along as the monitors were on the same video cards, if not, i was not able to, it worked the same as different video cards

3. with cinerama, enable, i could move apps from monitor to monitor, but it was way too glitchy way way way too glitchy,

well what a downer! linux just isnt good with multiple monitors, more than 2 monitors, nvidia drivers are not good either with multiple monitors on linux

the only solution that i have is to buy a video cards that supports the most monitors, or go back to windows

pny nvs 810 supports 8 monitors but it is 800 usd, too much money! i might end up purchasing that card if there is a sale



windows is still king for multiple monitors
