How to setup dual monitors

Post by gibbs1984 » Mon Aug 05, 2013 7:48 am

I found a couple of old monitors in my mums garage so I want to use one of them to have dual monitors if possible but I have no idea how to set it up.

Feel a little bit embarrassed with this but obviously with the monitor I have now it’s plugged into my graphics card and a power supply so do I have to do the same with the other monitor and if so I don’t think I have anywhere to plug it in.

No need to be embarassed. 19 Views and nobody till now has replied should tell you something, LOL. I think everyone hates the dual monitor type questions. Basically you set up each monitor using XRANDR command, at first with safe settings, especially for monitors you can’t be sure of their capabilities. A safe setting is usually something like 1024x768_60Hz.

I’d test each one individually on the VGA plug first before attempting to set up dual monitor only to discover you were wasting time on one that was dead as the second monitor and didn’t realize it. That sounds funny, but it’s been done before. I know.

Unless you are splitting the same image to two monitors, you’ll need two video outputs. If this is on a desktop you can swap to a card with two outputs which will send two signals. Some cards may have two outputs on them but only can use one at a time. Another option is to have a second video card added, but that means possible video driver problems. Some newer motherboards allow you to use BOTH onboard video and added card, each to a different monitor, most older ones it’s either one or the other, but not both.

Easiest is a card that will support two monitors. If this is a laptop it should support both the one on the laptop and the one added to the VGA port, but your description sounds like a desktop.

After a little more digging I’ve found that my graphics card (GeForce 9600 GT) has 1 DVI port and 1 HDMI port (that I can see anyway).

My current monitor is currently connect to the DVI port (through a VGA connector) to the VGA port on the monitor.

That leaves the HDMI port so I’m going to buy a HDMI to VGA adapter so that I can plug it into the old monitors.

I’ll worry about the software side then

Thanks for the tip too, I spent about an hour figuring out why my monitor wouldn’t work before only to realise that I have plugged it into the onboard graphics card and not the new graphics card that I had just fitted

Will report back once I get my cable

I was looking around for a cheapie that would meet your needs and got sidetracked by my surprise to discover http://www.geeks.com exists no more. Seems it died just 3 days ago, according to notice on their site. I built my first computer (shuttle hot-569 motherboard) with supplies from them and used them over the years. Lately their stock had fallen a bit too far behind times for me, but I always checked them first, just in case. Once I got over the sad shock of that, [url=http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1734303&CatId=3669]I found this one which fullfilled your needs[/url] and seems is Linux friendly too. I haven’t checked it in the hardware section for Mint yet.

Oh, as I recall, HDMI can’t convert to VGA without a digital to analog device.

Spearmint2 you are correct about the HDMI to VGA. Also something to think about is if there is going to have to be HDCP, if so I don’t believe this will work. Again I could be wrong.

yeah, I think I’d toss another video card in it, have two of them, especially if using older monitors which no doubt are just VGA also.

[SOLVED] Dual monitor desktop help in linux mint 20 (AMD gpu)

Post by zed14 » Wed Mar 03, 2021 8:01 am

Hello guys, I am new to linux and linux mint, installed it yesterday, and i am loving it, however I am having this problem that my second monitor isnt getting detected my linux mint, both displays (g34wqc and benq zowie xl2411p) are connected with DP cables, but only the g34wqc is getting detected, when i run the xrandr command i get this :

xrandr: Failed to get size of gamma for output default Screen 0: minimum 3440 x 1440, current 3440 x 1440, maximum 3440 x 1440 default connected primary 3440x1440+0+0 0mm x 0mm 3440x1440 89.00* 

I read in some forums that it could be because of drivers, so i tried to install the amdgpu pro drivers from their official website and managed to install them, but when i rebooted it caused linux mint to go into fallback mode, so I had to unistall it, reboot and everything was back to normal, and searched a bit more and it seems that linux mint 20 comes with integrated drivers for amd and i cant install the pro amd drivers in it, and that is not a problem for me, I just wanted to see if i could get the dual monitor setup to work, i aldrady installed everything on driver and update managers.

If anyone could help me in getting both displays to work that would be super nice. Thanks in advance for your time guys
