Bounty: 50

For a couple of years now I haven’t been able to get my LG Flatron W2261VP to work as an external monitor for my ThinkPad T460s running Kubuntu (currently 18.04.3 with Kernel 4.15.0). It’s connected through HDMI since the T460S doesn’t have a VGA slot.

In the beginning, I plugged in the HDMI cable and the monitor was recognized in the system settings, but I couldn’t turn it on. Every once in a while I tried again and sometimes the monitor didn’t even appear in the system settings. Currently it does. But as soon as I plug in the cable, the system partly freezes/slows down and it’s impossible to work, because the laptop monitor turns black every couple of seconds. The external monitor remains black and sometimes displays a messages about HDMI power saving mode.

I have been able to connect other external monitors through HDMI though. I also checked the cable with another machine. For a short time, when Kernel 4.10 was installed, the problem disappeared (see Can't get external monitor to work through HDMI (Thinkpad T460s, Kubuntu)).

I have also tried using the monitor with Live USB (both Ubuntu 18.04 and Kubuntu 18.04), but the problem is the same.

Any ideas for a solution? I attach some command results.

Bounty: 50

For a couple of years now I haven’t been able to get my LG Flatron W2261VP to work as an external monitor for my ThinkPad T460s running Kubuntu (currently 18.04.3 with Kernel 4.15.0). It’s connected through HDMI since the T460S doesn’t have a VGA slot.

Every once in a while I tried again and sometimes the monitor didn’t even appear in the system settings. Currently it does. But as soon as I plug in the cable, the system partly freezes/slows down and it’s impossible to work, because the laptop monitor turns black every couple of seconds. The external monitor remains black and sometimes displays a messages about HDMI power saving mode.

I have been able to connect other external monitors through HDMI though. I also checked the cable with another machine. For a short time, when Kernel 4.10 was installed, the problem disappeared (see Can't get external monitor to work through HDMI (Thinkpad T460s, Kubuntu)).

I have also tried using the monitor with Live USB (both Ubuntu 18.04 and Kubuntu 18.04), but the problem is the same.

Any ideas for a solution? I attach some command results.

#StackBounty: #kubuntu #multiple-monitors #hdmi #thinkpad Why can't I (still) get my external monitor to work through HDMI? (Thinkp…

Bounty: 50

For a couple of years now I haven’t been able to get my LG Flatron W2261VP to work as an external monitor for my ThinkPad T460s running Kubuntu (currently 18.04.3 with Kernel 4.15.0). It’s connected through HDMI since the T460S doesn’t have a VGA slot.

In the beginning, I plugged in the HDMI cable and the monitor was recognized in the system settings, but I couldn’t turn it on. Every once in a while I tried again and sometimes the monitor didn’t even appear in the system settings. Currently it does. But as soon as I plug in the cable, the system partly freezes/slows down and it’s impossible to work, because the laptop monitor turns black every couple of seconds. The external monitor remains black and sometimes displays a messages about HDMI power saving mode.

I have been able to connect other external monitors through HDMI though. I also checked the cable with another machine. For a short time, when Kernel 4.10 was installed, the problem disappeared (see Can't get external monitor to work through HDMI (Thinkpad T460s, Kubuntu)).

I have also tried using the monitor with Live USB (both Ubuntu 18.04 and Kubuntu 18.04), but the problem is the same.

Any ideas for a solution? I attach some command results.

#StackBounty: #kubuntu #multiple-monitors #hdmi #thinkpad Why can't I (still) get my external monitor to work through HDMI? (Thinkp…

Bounty: 50

For a couple of years now I haven’t been able to get my LG Flatron W2261VP to work as an external monitor for my ThinkPad T460s running Kubuntu (currently 18.04.3 with Kernel 4.15.0). It’s connected through HDMI since the T460S doesn’t have a VGA slot.

In the beginning, I plugged in the HDMI cable and the monitor was recognized in the system settings, but I couldn’t turn it on. Every once in a while I tried again and sometimes the monitor didn’t even appear in the system settings. Currently it does. But as soon as I plug in the cable, the system partly freezes/slows down and it’s impossible to work, because the laptop monitor turns black every couple of seconds. The external monitor remains black and sometimes displays a messages about HDMI power saving mode.

I have been able to connect other external monitors through HDMI though. I also checked the cable with another machine. For a short time, when Kernel 4.10 was installed, the problem disappeared (see Can't get external monitor to work through HDMI (Thinkpad T460s, Kubuntu)).

I have also tried using the monitor with Live USB (both Ubuntu 18.04 and Kubuntu 18.04), but the problem is the same.

Any ideas for a solution? I attach some command results.

#StackBounty: #xorg #multiple-monitors #display #citrix Strange issue with Citrix remote desktop and dual monitor

Bounty: 100

Given the below:

  • Ubuntu 18.04
  • HP Compaq Pro 6300 SFF PC
  • 2 identical HP monitors

I have a dual monitor setup which works perfectly, apart from the Citrix remote desktop.

Citrix says that it detected multi-monitor support. In fact when I remote in to a full-screen session and then minimize the screen and resize, then I can see that the window Citrix created has the same size as the 2 monitors, but for some reason it is only presented on one of the monitors. (I.e. one monitor shows half of the remote session, the other half on the other monitor is always hidden.)

The PC has a VGA and a displayport output. One of the monitors is connected directly with VGA, the other with a displayport->vga adapter.

A strange thing is that no matter which display is set to be the primary display in gnome, Citrix always only shows itself on the monitor which is connected to the displayport output. The only difference is that if the one plugged into the displayport is set as primary, then citrix shows the primary section of the remote desktop (i.e. the one with the system tray), if the one plugged in the displayport is set as the secondary then citrix shows the secondary section of the remote desktop (which is normally an empty screen).

Normally this should work out of the box. Also no solutions to dual-monitor issues with citrix and linux I found on the web resolves this. Under Windows there are no issues with Citrix with the same setup.

Any idea?

#StackBounty: #multiple-monitors #display #display-resolution #amd-graphics #4k-monitor Mirror Displays of 2 different resolutions

Bounty: 50

I am wanting to mirror asymmetrically whereby the main monitor is a lower resolution than the HD TV we are using as a monitor. When the displays are in non-mirrored mode (spanning?) each monitor display properties allows me to set the resolution the the maximum of each monitor. When I switch to mirroring the HD TV drops down to the lower setting on the main monitor.

If it is not possible to do with one video card perhaps I can use both my video cards?

#StackBounty: #nvidia #multiple-monitors #intel-graphics #hdmi #xrandr HDMI (DP-3) no output 2560×1600 59-60Hz in Ubuntu 19.04

Bounty: 100

There’s no HDMI (which is DP-3 in xrandr) output on 2560×1600 59Hz or 60Hz in Ubuntu 19.04.
Whether I try it with intel or the nvidia chip, the output is limited to 30Hz. Please note that 2560×1600 with 60Hz is working fine in Windows 10 with the same cable and monitor.

Adding custom modes with xrandr on 60Hz won’t work. Changing configuration won’t work. However things will work as long as I keep the 30Hz setting with the custom xrandr setting.

#StackBounty: #graphics-card #multiple-monitors #gpu #troubleshooting #pci-express GPU suddenly not being recognized in PCIe slot at all

Bounty: 50

The other day I updated to Windows version 1903. Things ran fine for a couple of days. Now when I turn on my PC my 2 monitors stay dark and nothing happens; I can see that the CPU cooler and GPU fans are running. LEDs are on too. Sometimes keyboard and mice don’t light up.

Relevant Parts

CPU: i5-6600k

GPU: GTX 1070

Motherboard: AsRock Z170M Extreme4

Dual monitor setup: 1 HDMI, the other mDP/DP.

Things I have tried

  • looking in Event Viewer for any relevant information (nothing that I could identify)
  • switching to motherboard output (HDMI) allows me to boot and I have visuals on one screen
  • using this I was able to access the UEFI/BIOS screen:
    • it says the PCIe slot that the GPU is physically plugged in is empty
  • tried switching PCIe slot, same issue
  • I cannot rollback the update because I deleted the Windows.old files

The weird thing is that initially, I tried restarting my PC several times and once or twice I was able to boot with my GPU, but only if the DP cable was unplugged. After another restart, I have been unable to replicate this.

I have not tried clearing the CMOS yet.
