#StackBounty: #dual-boot #grub2 #nvidia #multiple-monitors Can't Boot on Dual Monitor

Bounty: 50

Summary of issue: Can’t see GRUB2 boot menu on monitor connected via DVI port.

Up until recently I had everything working fine for my Windows 10 / Ubuntu 18.04.2 dual boot setup. I had two monitors: one connected to HDMI and the other to Displayport on graphics card and using a Display-Port -> DVI cable to plug into second monitor. My primary monitor was the one connected over HDMI.

The monitor that I had plugged into HDMI failed and I bought a new one. To make the most of my new monitor, I want to connect it over Displayport. This means my 2nd monitor is now connected DVI-D to DVI-D.

Given the priority order of GPU (GTX 1050 Ti) is DVI, HDMI, Displayport this means that for booting my old 2nd monitor is now primary before the OS is loaded.

However, I am unable to see the dual boot menu. Instead I see a few lines of coloured pixels at the top of my 2nd monitor (the one connected via DVI).

Windows boot works fine (if I change BIOS to boot straight to Windows). However, the only way I can access Linux is to unplug my 2nd monitor. Then the Displayport monitor is the only one and everything works fine. Once into Linux I can then plug in the second monitor to the DVI cable and it is recognised and works.

I have tried the following (incrementally and individually):

  • Set GRUB_GFXMODE to 640×480
  • Set GRUB_TERMINAL to console
  • Changed display driver to NVIDIA rather than Linux default

Note that after updating the GRUB2 settings in /etc/default/grub I have ran the grub update. I can see the changes have taken effect when I boot with 2nd monitor unplugged.

This has me tearing my hair out – any suggestions very welcome. If I’ve ommitted any key information, please comment.

UPDATE 1

I have tried booting from a Linux boot USB. I see the same result (i.e. a few coloured lines of pixels at top of screen). Is GRUB2 compatible with DVI-D?

#StackBounty: #gnome #multiple-monitors #java #17.10 #eclipse eclipse on Ubuntu 17.10 – toolbar drop down menus and pop ups moved when …

Bounty: 50

When I use eclipse oxygen on Ubuntu 17.10 with a dual monitor set up, the drop down menus and the pop ups from the toolbar are moved downwards:

eclipse – drop down menu:
eclipse - drop down menu

eclipse – pop up:
eclipse - pop up

Additionally, on start up, the eclipse oxygen icon is not displayed centered, but on the upper left corner (this however happens independent on the number of monitors used):

eclipse – start up icon:
eclipse - start up icon

I already tried reinstalling eclipse a couple of times. I also deleted the .eclipse folder and the eclipse workspace before reinstalling.

EDIT:

Apparently the problem with the drop down menu can be bypassed, if one aligns the two displays at the top, rather then the bottom:

drop down menu moved:
drop down menu moved

drop down menu correct:
drop down menu correct

Is there a way to align the two displays at the bottom and still have drop down menu (and pop ups) at the correct position?

The start up icon is still in the upper left corner and seems not to be affected by the display alignment.

#StackBounty: #windows #graphics-card #multiple-monitors #hdmi #tv How to enable TV display with MultiMonitorTool or similar?

Bounty: 50

I have two monitors and one TV connected to same computer with Windows 10.

enter image description here

An image I found online to describe the setup

I know I can choose to extend or duplicate, or not, to second screen doing WIN + P, but that doesn’t work for the TV as it is a third display.

I would really like a shortcut so I dont have to open display setting each time I want to use the TV as display.

My computer is a laptop with Intel HD 630 + Nvidia GT 1050 Ti but Im pretty sure it only uses the HD 630 normally. It also has an external graphics card usb hub using DisplayLink drivers. TV is connected to HDMI on laptop while two monitors are connected via the external hub. The TV is a Samsung smart TV.

With the freeware MultiMonitorTool it’s quite easy to make a command line command that I can save as a shortcut that disables the TV:

enter image description here

MultiMonitorTool.exe /disable 1

This disables the display perfectly just as I want. (1 being the monitor number of the TV)

Unfortunately the TV display can not be enabled again via command line using MultiMonitorTool for some reason using:

MultiMonitorTool.exe /enable 1

If I run the enable command nothing happens.

(When making tests on other two monitors I can enable them with this command so its a problem that is specific for the TV)

If I manually open Windows display settings I can select the display, scroll down and choose “Extend to this display” to enable it.

enter image description here

I open display settings and there it is…

enter image description here

Selecting “Extend…” enables the TV display again

enter image description here

Now the display is enabled, and can be disabled with the shortcut again

My question is, why doesnt it work to enable the TV and what can I do to enable it via command line instead of having to go to settings each time?
