Hello,
I just installed openSUSE 13.1 (with KDE) and on Windows I run three monitors, two on my Geforce 560 and one on the onboard Intel 4600 (on my i5-4570) I’ve been googling for a while but I can’t seem to get that third monitor to work in openSUSE. Do anyone have any suggestions?
Thanks!
It’s not a trivial exercise to configure, and a lot depends on the graphics hardware concerned. Some previous discussions on the subject:
https://forums.opensuse.org/showthread.php/495249-Dual-Graphic-Card-and-Dual-Monitor-Problem
Well, I just can’t get the onboard gpu and the third monitor to show up, I’ll take a look at those topics though. I hope I can get it to work with my (close to) non-existant Linux skills 
Thanks!
What output do you get for the following commnad:
/sbin/lspci -nnk | grep VGA -A2
Note also if you use the NVIDIA drivers it changes mesa and the Intel won’t work. And just to be clear this is not an optimus notebook right?
/sbin/lspci -nnk | grep VGA -A2

Nope, it’s a desktop I built myself
I couldn’t find an edit button, so I had to reply.
I also tried this command, after seeing it in another topic:

So are you trying to run the NVIDA driver? Keep to the OS driver
This is the situation after a clean installation. I have no idea how to change such a thing but I’ll look into it, thanks!
Hmmph, wasn’t expecting that grepping the lspci output to be missing “VGA” for the Intel adapter … perhaps they’ve switched to calling them simply “Display controller” now. (Time to adjust troubleshooting 101 to: /sbin/lspci -nnk | grep -e “VGA” -e “Display” -A2 )
Anyway, the hwinfo output appears to show that the intel adapter is configed just fine.
You should be able to achieve what you want simply with xrandr now.
If you want to check the basic requirement is met (i.e. see the relevant section of “man xrandr”):
xrandr --listproviders
if so, then issue
xrandr --setprovideroutputsource 1 0
After that you should be able to turn the additional monitor on via xrandr itself or through a frontend to it … try using kscreen (if you’re running KDE), as it should be self evident.
And then after that, setup the above in a startup script so that its all evoked automagically each time you boot.
What kernel are you using? (run “uname -r”) … you might want to update to a newer kernel to get the benefits of dynamic runtime power management (don’t remember which kernel it was added to the nouveau or intel kernel drivers) … it will save you battery life
If you want to switch to the nvidia prop. drivers, consult the nvidia release documentation, as it outlines the steps you need to take.
Disregard the point about runtime power mgmt … I was starting to confuse things by thinking about hybrid laptops
nothing to change if you have not installed the NVIDIA driver it is not there forget about it.
This worked perfectly, thanks a lot!
