Dual monitor setup


In addition to the standard single connection commonly used, so that the switching is controlled exclusively by the software, it is often possible to make use of two separate connections. Depending on the particular machine and the BIOS, you may be able to connect to two different ports–for instance, one VGA and the other HDMI.

Software adjustment

Multiple monitors are managed in MX Linux with Start menu > Settings > Display. You can use it to adjust resolution, select whether one clones the other, which ones will be turned on, etc. It is often necessary to log out and back in to see the display you select.

Finer control of some features is sometimes available with xrandr. Xfce 4.12 has some limitations with multiple monitors, but 4.14 has expanded capabilities including storing two different configurations.

  1. Windows 10 has no problem using both my monitors. Therefore I assume the Bios should not need any changes. My MX-Linux monitor is connected via an Nvidia card and detected as Device-2. My Device-1 monitor is connected using Intel UHD Graphics 630. The Display Settings does not see the Intel monitor but the quick system info sees both monitors. I’m running Kernel 4.19.0-amd64 x86_64. The graphics info is:
    Graphics: Device-1: Intel UHD Graphics 630 vendor: Gigabyte driver: i915 v: kernel
    bus ID: 00:02.0 chip ID: 8086:3e92
    Device-2: NVIDIA GK208 [GeForce GT 710B] vendor: ASUSTeK GK208B driver: nouveau
    v: kernel bus ID: 01:00.0 chip ID: 10de:128b
    Display: x11 server: X.Org 1.20.4 driver: modesetting unloaded: fbdev,vesa
    resolution: 1920×1080~60Hz
    OpenGL: renderer: NV106 v: 4.3 Mesa 18.3.6 direct render: Yes

  2. My device does not show the next monitor after following instructions above via advanced settings. The window message has a few options below like – identify new screens during start up – but sadly, only one screen is shown. 🙁

  3. When I used as svga link on a second monitor in trial mode it worked as two different screens, master and slave but when using the HDMI link the second screen is cloned and controls did not affect it.
    I want to use MX to move on from Ubuntu but I need two different screens. Do you know if I will get them in the full install?

  4. Ich habe am HDMI-Anschluss einen 27 Zoll Monitor und am DVI einen 24 Zoll. Wenn ich beide Monitore mit der gleichen Auflösung (1920 x 1080) einstelle funktioniert`s. Bei verschiedenen Auflösungen ging es nicht. Allerdings ging der ArbeitsflÀchenumschalter nicht! Aber damit kann ich leben.

  5. I had a Dell Vostro laptop on LinuxMint 19 as media device connected to a HDMI projector. I did not set up anything special in Mint to have it working just fine.

    The HDD crashed yesterday. Since I had a USB with MX-Linux 21 ready to use I reinstalled MX-21 in place.

    Sadly MX-21 cannot detect the HDMI projector. Maybe the AHS version would have done better ? I guess I will switch back to Mint to be sure having the projector working out of the box.

  6. I have an HP Z Book, M9R63AV, which does not support dual/extended monitors with MX Linux. It does work in Windows 10 and Ubuntu 21.10.

    lspci shows two video cards:
    Intel HD Graphics 530 (rev 06)
    Nvidia GM107GLM [Quattro M2000M] (rev a2)

    A display dialog will popup when plugging or unplugging the external monitor but it only shows one display called “Laptop”.

    What is the best way of debugging this?
