#StackBounty: #nvidia #display #20.04 #laptop Can't physically turn-off built in display

Bounty: 100

TLDR; Is it possible to physically turn off a built in display for a laptop so a docking station could utilise all available display outs.

I am struggling to physically turn-off a laptops built in display for Ubuntu 20.04. Due to the built in display always being available, when I attempt to connect more than a total of 3 [internal or external] monitors to my Dell Docking Station WD19 Thunderbolt in Settings > Screen Display I receive the error (in the windows title bar):

Changes Cannot be Applied
This could be due to hardware limitations

It is worth noting that the documentation for the docking station states:

NOTE: : Linux operating system is unable to physically turn-off built-in display, the external display numbers will be one less than the display numbers listed in above tables.


Additional Info:

  • Graphics card: NVIDIA GeForce GTX 1650 4GB GDDR5
  • Graphics driver: NVIDIA Corporation: TU117M [GeForce GTX 1650 Mobile / Max-Q] - Using NVIDIA driver metapackage from nvidia-driver-440

#StackBounty: #windows-10 #display #nvidia-graphics-card #gaming Windows 10 graphics kernel crashes randomly when playing games

Bounty: 100

I’ve been having a very odd hardware issue on my PC lately

  • Windows 10 (ver 1904)
  • 2014 vintage Intel i7 4790
  • 16GB RAM
  • "EVGA Nvidia GTX 980 FTW" graphics card
  • Gigabyte "H81M-DS2V" motherboard
  • Samsung 3440×1440 monitor @ 60 Hz via either HDMI or DisplayPort

I’ve been using this PC for casual gaming for over a year now, it plays Doom 2016 (for example) very stably and at high graphics settings. Recently I’ve been playing another game (Snowrunner) and every so often the monitor just goes completely black as if the video cable had been unplugged (cables are fine and secure). Replugging the HDMI cable does nothing (it does not even make the "device detected" noise that Windows usually makes) which leads me to believe that the GPU itself has gone into a failure state of some kind. The card simply goes idle as if it has fallen off the PCIe bus completely (I can’t prove that because frustratingly there’s no screen to look at).

However Windows does not crash and remains responsive (I can still play/pause media player which is usually running in the background using hotkeys on my keyboard). I can still use "[WIN+X], [U], [U]" to safely power off the PC. Oddly, power-cycling the PC does not automatically bring back the display unless I then consequently replug either the HDMI or DisplayPort cables.

I’ve gone through the process of removing the Nvidia drivers using the DDU tool and physically removing the graphics card, cleaning the PCIe contacts carefully with isopropyl alcohol and blowing any dust out of the cable sockets with an air duster). Then I reinstalled the Nvidia drivers to the latest version. The problem remains.

The Windows "View Reliability History" tool tends to report the following for a 187 code:

Description

The "Code" number changes each time, sometimes it’s 141 report…

The other problem is that this is intermittent. I can go all week without this error and then get 2 in the same day. It does not appear to happen more when the CPU/GPU is under heavy load (although Snowrunner is a very graphics intensive game) it can just as well happen when the system is cold and hardly spinning it’s fans. Then again Oblivion is not a graphically intense game and that causes it too.

Can anyone tell what might be causing this and what can be done to fix it?

EDIT: This problem also occurs when playing "TES4 Oblivion" with the same kind of error codes.

#StackBounty: #lubuntu #display #brightness #redshift #f.lux F.lux or redshift and lubuntu issues

Bounty: 50

I’m a noob. Putting this out there right away. Using Lubuntu 19

I want a blue light filter. So I’ve installed f.lux, but when I adjusted the brightness on my laptop it toggles or flashes between the screen without f.lux and then back to f.lux as I increased or lowered brightness. So I uninstalled f.lux and reinstalled it. Now it doesn’t work at all.

As for Redshift, when I change the brightness it automatically just switches back to the brightness level that redshift has assigned. This is quite different then how it acts on other operating systems where you can lower or increase the brightness yet keep the effect of redshift–which is all I want. Can anyone help, or should I just install Ubuntu?

#StackBounty: #multiple-monitors #display #20.04 #external-monitor Primary display flickering cursor, secondary display flickering blac…

Bounty: 50

I changed from a version of Windows that is not supported any more to Ubuntu 20.04.0. This laptop is connected to a TV monitor with a VGA cable (xrandr calls it VGA-1). The laptop does not have a HDMI port. I have had no issues on Windows with this cable at the same resolution and framerate.

The problem is that when I log in to a user (after a restart, and after logout), the laptop screen sometimes shows a black screen with the cursor flashing once every 0.5 seconds (best guess at timing). At this time, the secondary display flickers at the same rate between a black screen and no signal.

Sometimes the flickering stops after around 3 seconds and the desktop shows on the laptop monitor. Other times, the flickering continues indefinitely. I have tried pressing super+1 to open the first application (gedit) in the dock while it is flashing. gedit is not open when I disconnect the cable. Pressing super+1 after I can see the desktop opens gedit as expected.

The flickering can be temporarily fixed (until the next time the problem occurs after trying to log into a user) by disconnecting the VGA cable and reconnecting it. After reconnecting the cable, the desktop does the "popup" animation (expand from single point at center of screen to the whole monitor). This is regardless of how long I wait before disconnecting and reconnecting the cable.

The flickering does not happen at all when I log into a user if the VGA cable is not connected.

I have tried with and without fractional scaling (both at 100%) in single monitor mode on both laptop and TV display. The laptop resolution is 1440×1900 at 60 FPS and the TV resolution is 1280×720 at 60 FPS.

What can I do to prevent the "flickering indefinitely" while still being able to use the "single display" mode (on laptop monitor xor TV monitor)?
