Can't add a second monitor

I just installed Leap, YAST recognized my second monitor but in display configuration only appears my laptop monitor. Laptop Lenovo G530 with Intel 4 mobile series. I tried with 2 monitors.
Thanks in advance.

I just tried hooking up a second monitor also. Same problem. I’m using a Dell XPSL502X with nvidia optimus. The nvidia drivers and bumblebee are installed and appear to be working fine, but when I plug in a secondary monitor, it doesn’t recognize it.

What are your setting in Configure desktop?

I hope you installed the nvidia-bumblebee package and ot the regular NVIDIA driver

You might want to run xrandr and see what it sees

In display and monitor settings it only shows laptop screen, no secondary monitors show up.

nvidia-bumblebee is indeed installed, and it works properly. I can run the nvidia card with optirun.

xrandr returns:

with a second monitor connected. When I disconnect it, nothing is listed below VIRTUAL1.

Also, I’m connecting the monitor to a mini-display port, which I think should be DP1 but I’m not sure. I don’t know why it’s showing up as virtual1.

I’m guessing this is a problem with the driver, as the external monitor worked just fine in 13.1.

Looking at the hardware info, I have the below information:

>> misc.5: misc data
Oopy, could not figure out *the* active display adapter!

and then the drivers for my video cards are:

Obviously, the could not figure out active display adapter error seems problematic, and can anyone tell me if the i915 driver is appropriate for the intel integrated graphics controller? I vaguely seem to recall looking at this information at some point in 13.1 and I’m fairly sure there was a different driver listed, although I have no idea what it was.

You need to identify which Desktop you’re using, and if KDE possibly the Plasma version.

Nowadays,
Assuming the second monitor is detected, configuring is the province of the Desktop’s tools.

If you are using proprietary nVidia drivers, you should also install the proprietary nVidia software which takes priority for configuring.

TSU

I’m using KDE Plasma 5.4.2. The thing about the monitor being detected, is that it’s showing up under Virtual1 rather than DP1. Unless of course, this is supposed to be normal behavior, but I would assume not.

I was also using KDE in 13.1, which recognized the secondary monitor just fine. I don’t remember which version of KDE was installed though.

Be sure you are using the Desktop settings for plasma 5. If you upgraded the older settings program is still there with the same name and the menu program does not display the plasma5 version. go into edit applications (right click the menu icon) redo the Configure Desktop entry to indicate it is the new plasma5 version and be sure that is what you use. keep the old one because in some cases you may need it for some stuff that has not yet moved to 5

Do you mean make sure it says “systemsettings5” on the command line? It’s set to that. I did not upgrade, I wiped the linux partitions and installed 42.1.

Then I don’t know look to your video card settings.

Ok, thanks. I’m still pretty much a noob, where do I find my video card settings?

Depends on what video card and drivers For NVIDIA is is nvidia-settings but not sure that works with Optimus systems since all output goes through the Intel GPU. Check with the manufacturer . in KDE in the menu look in System-configuration

Anyone have any other ideas as to what might be causing this? The intel video driver should be able to operate the external display on DP1, but for some reason when I plug in an external monitor it is showing up under Virtual1 in xrandr. Anyone know how to get it to show up under DP1? Thanks.
