Problems with Dual monitor setup

I have installed clear linux Desktop. It seems to work with a single monitor, but when I add a second monitor the cursor starts stuttering and jumping around the screens. Has anyone had this issue? My computer is an NUC5CPYH I have one monitor connected to the VGA port and one connected to the HDMI port.

i use 2 monitors without any problems
(wish i could figure it out how to install it even)

Are you in CLI or Desktop environment?

If x is running then…

Are the monitors from the same manufacturer? Are they same size & frequency? Is display setting in mirror mode?

Either way xrandr or Arandr (gui) could be run to control display settings

I have two monitors both 27’ Samsung no issues at all. Can even use laptop with open lid

I am running the desktop environment. Monitors are the same make and model. I am using single screen mode(Extended -Mode).
I am thinking that running one off of the VGA port and one of the HDMI port could be the issue, although I have done that with other computers.
My next step is to upgrade the BIOS of the NUC to see if that helps. Thanks for your insights.

If you have display port 1.2 and later, you can try to daisy-chain your monitors.

Using both vga and HDMI ports should not be the cause. Because other people also do that.

Still no luck. It seems as though the Vga does not want to cooperate.
the NUC I have only has one HDMI out and one VGA out for displays.
oddly enough, when I connect the second monitor (VGA) the display sees it and shows the second display on the configuration screen with the correct model. I can then apply the screen settings and the cursor will travel off the edge of screen “1”(HDMI Display) to the left as if it is moving to display “2” (VGA Display) but the screen remains black with “no signal” message.
I did install Arandr as suggested but changing the setting using it made no difference.
I suspect this may be an intel video driver issue. Any suggestions on next steps to troubleshoot the issue?

Open a GitHub issue then. I’m sure there are developers having a NUC so they could investigate this.

I will do that. thank you @doct0rHu

does clear linux have a bundle that includes “read-edid”, “get-edid” and “parse-edid”?

Can you try getting EDID info with xrandr? There is a Parse-EDID perl module in the perl-extras bundle.

on another thread I saw this:

[     2.496] (II) modesetting: Driver for Modesetting Kernel Drivers: kms

That is likely due to not having the intel driver installed and I don’t think it is part of Clear anymore, favouring the modesetting driver.

Since the NUC I am using lists the VGA compatible controller as:
VGA compatible controller: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller (rev 21)
Is it possible that not having the intel driver installed is causing my dual monitor issue?

Here is the output of my /var/log/Xorg.0.log when I try and boot with both of my Benq 2280 monitors plugged into my NUC5CPYH. (I have removed some of the lines from this file, which seemed unrelated to display, so that I could post it. It appears to be to long for a single post

One monitor is plugged into the HDMI 1 on the monitor and the single HDMI output on the NUC.
The second monitor is plugged into the VGA(D-Sub) on the monitor and the VGA out on the NUC.
The NUC Bios is set to HDMI Primary output and VGA(analog) as 2nd output.
When the system boots, the HDMI monitor is the only monitor that displays an image, the vga connected monitor displays no signal.
But the HDMI monitor image is a grey screen which acts like it is the secondary monitor of an “extended” display. So there is no input filed to enter my password.
The NUC acts as if the VGA connected monitor is active and is my primary monitor and So I assume it contains the Login screen(even though it is reporting no signal). In order to get the HDMI monitor to display the login screen is to disconnect the VGA Cable from the NUC…
At that point the active screen displays the log in prompt and I am back to a single monitor functioning system.

Also here are my kernel boot args in case that might shed some light on my issue:

initrd=\EFI\org.clearlinux\freestanding-00-intel-ucode.cpio initrd=\EFI\org.clearlinux\freestanding-i915-firmware.cpio.xz root=PARTUUID=52317e75-7773-4bee-ba1f-29f832b56b3f quiet console=tty0 console=ttyS0,115200n8 cryptomgr.notests init=/usr/bin/initra-desktop initcall_debug intel_iommu=igfx_off kvm-intel.nested=1 no_timer_check noreplace-smp page_alloc.shuffle=1 rcu_nocbs=0-64 rcupdate.rcu_expedited=1 rootfstype=ext4,btrfs,xfs tsc=reliable rw

I have some obviously (basic) Linux knowledge, but would be very thankful for some help to solve this issue (as I have heard promising things about clear linux). I am more than willing to RTFM but would appreciate any help in pointing me in the right direction.

@mesiment Just in case you hadn’t seen this.

@kfrank I didn’t see the link to your issue on github, would you mind adding it here just for reference?

sure @william.douglas, could you point me to where I should add it on github?
To be clear there looks like a lot of subsections on the Clear Linux github project. Not sure where this belongs.

sure william, could you point me to where I should add it on github?
