#StackBounty: #display Size (depth) of Pi 7" Display + driver?

Bounty: 50

I’d like to know the approximate depth (as in, z-axis) measurement from the very front of the Raspberry Pi 7" display (with display driver mounted) to the furthest back piece, excluding the Pi; I’ll mount the actual Pi (4B) separately, extending the power cables and FFC. I couldn’t find dimensions of this anywhere, only the screen itself.

PS – Or, if anyone has yet found a way to extend the (orange) ribbon cables and mount the driver board separately altogether, that’d be amazing. (said cables would have to be able to last being constantly flexed though, as it’s part of a laptop)

Thanks!

Bounty: 50

At work, we are developing programs, each developer having his own private VM under CentOS.
I disconnect my session at the end of the day, then the next morning I start Remote Desktop under Windows and join it again.

But today, I went on a different Windows workstation, with lower resolution display.
I started my remote session with Remote Desktop as usual in direction of CentOS who led me to another, old, already opened session of mine that I started one month before…
I was troubled. I disconnected, came back to my previous workstation and retrieved the one I was expecting.

Question 1 : How this behavior explains itself?

Question 2 : How to drop my old session from the main one?

When I do a who command from my main session, I see myself + a number of me equals to the number of shell I have opened with KConsole.

How can I list how many others session like the one I found today are still opened and how can I close them?

#StackBounty: #display #multiple-monitors #gpu #nvidia-geforce DisplayPorts on GPU suddenly not working on certain monitors

Bounty: 100

I have no idea what is going on but after a morning of troubleshooting I am at a loss. I am running on Windows 10 Home latest (Microsoft Windows 10 Home, Version 10.0.18363 Build 18363).

I have a GeForce RTX 2080 Ti, it has 3 DisplayPorts and 1 HDMI input.

Up until this morning I had this setup:

  • Main: 4K 144hz DisplayPort Monitor.
  • Satellite: 144hz DisplayPort Monitor.
  • Satellite 2: 60hz HDMI Monitor.

The last DisplayPort I use for my Valve Index VR headset when I am playing.

This morning the main display would not work, I tried swapped cords around on different ports, I did a fresh uninstall and reinstall of the latest display driver. I used a HDMI (Monitor) to display port (PC) cable on my DisplayPort Satellite monitor to see if it was the cord since I did not have an extra DisplayPort cable and it then let my main and satellite to work, the HDMI is no longer working now but I have my 2 main ones.

I then ordered a new DisplayPort cable for my main monitor to see if it was an issue with the cable, but plugging it in immediately turns off my main display and my HDMI monitor comes back on, I am so baffled on what is happening.

I can actually get it to work in a very specific port configuration and if I unplug the HDMI from the 3rd satellite the main monitor stops working again, so I temporarily have a fix but I occasionally hook up my satellite monitor to a laptop and would like to still solve the root problem.

Thanks in advance for any help, here is my system info:

#StackBounty: #windows-10 #graphics-card #display #multiple-monitors Cannot change "Active Signal Resolution"

Bounty: 100

I have a (First 301 GD Live) monitor with a 2560×1600 native resolution that intermittently fails to identify itself properly to windows. I have just moved to a new office and when trying to get started again the monitor is just not being recognized. Windows just says it’s a "DVI" monitor. Windows now shows that the "recommended" resolution is 1280×800. If I go to advanced display settings and list all modes and then select 2560×1600/60Hz then the "desktop resolution" becomes 2560×1600 but the Active Signal Resolution remains at 1280×800 and the picture is horrid – like an upscaled low resolution image.

I tried setting the resolution via the NVIDIA Control Panel to 2560×1600 but the Active Signal Resolution remains at 1280×800 and so the picture is still awful.

I also tried power cycling the monitor itself several times to no avail (this had helped in the past).

My graphics card is a GeForce GTX 1650 Super.

Is it possible to instruct the graphics card to send out a 2560×1600 signal that you specify, regardless of whatever monitor the computer thinks is at the other end of the cable?

#StackBounty: #nvidia #xorg #display #overheating V-Sync and weird behavior (causing overheating)

Bounty: 50

In some game (Eve Online), VSync is somewhat broken on Ubuntu. Well. Maybe it is coming from the game itself, but some things tell me I can configure Ubuntu to get it work.

How did I find out about that issue

My computer was overheating when running that game, but only when I select that Windows (I could run a htop above it, and my CPUs cool down immediatly)

Expected behavior

VSync works fine and caps my FPS to 120Hz, as my laptop’s monitor is.

Faulty behaviors

Well, there are differents things to say that drive me mad.

  1. Laptop monitor alone

I’ve narrowed the issue coming from the VSync because my FPS went all the way to the moon (400 to 800, and I don’t have Linus T. computer) when I selected the Window, and where capped to 60 when I selected another Windows.

I tried to fix that by bypassing DE settings by editing /etc/default/grub and adding nvidia-drm.modeset=1 to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". It went well tho, my FPS were capped. But my CPU didn’t like it, and all X are pretty laggy.
(that modification allowed me to see "Synchronized = 1" on nvidia-settings).

I then reversed that and told myself I’ll buy an external fan, don’t do anything requiring me not to alt-tab to another windows time to time to cool down my CPU, as a workaround.

  1. I plug an external monitor

Well, I wouldn’t be here if I didn’t observe a again weirder event about that. If I do have an external monitor plugged in (and turned on, obviously), and I launch Eve Online, wether the window is on my external monitor or my laptop monitor : everything works great !!!

I do not understand.

Workaround ? Resolution ?

Right now, I’m thinking more about a workaround from a resolution.

  • either simulate the existence of that eternal monitor (althought nothing is plugged in), with "turn on" and "turn off" scripts.
  • or resolve that issue, once for all

You’ll find all, I hope, you need, here, about my computer (inxi, xrandr)

No external monitor plugged in

Experiments :

  • Gnome/KDE : same results
  • KDE compositor on/off : same results
  • Eve’s settings "interval one" is what I have when I’m at 60FPS with an external monitor. When I set "imediate rates", it goes all to the moon (and client crashs, eventually). Conclusion : "interval one" works (VSync is working to 60 FPS)

#StackBounty: #multiple-monitors #display #thunderbolt External Monitiors via TB3 Only Occasionally Work, Ubuntu 18.04

Bounty: 50

My work computer setup was recently upgraded with a Thunder Bolt 3 docking station. I’m running Ubuntu 18.04. It connects via a USB-C port on my computer. When I plug it in, the external keyboard and mouse always works, but 80% of the time the external monitors do not work. My computer detects them via the TB3 but the monitors just say no signal detected. At the moment, to get it working I spend 5 minutes turning the monitors on and off and re plugging in the USB-C cable from the TB3. It eventually works but I’m wasting a lot of time every day because I have to repeat it every time I return to my office. Any ideas?

The graphics card is an Intel UHD Graphics. My xrandr input is the same whether the monitors detect my computer or not and is here

Any ideas? Thank you for your time. Since it works occasionally it seems like there must be something I can do

#StackBounty: #display #hardware-failure #external-display #displayport #capacitor Monitor never detects input, turns off within a few …

Bounty: 50

My monitor has caused me troubles before, whenever I unplug it and replug it, it could take ~1 hour to detect the input. In the past I ensured not to unplug it, so over nearly a year it didn’t cause me any trouble.

Then today I built a new PC and plugged my monitors into it, now one of them will not work. However I tested using my old PC, the issue is the 100% the monitor

Troubleshooting / info:

I tried a working HDMI cable into a working PC. I have 2 identical monitors, so I even tried the working power cable, still nothing.

If I select a source that has no input, ‘Check Signal Cable’ shows forever, which is expected and means it’s probably not a power issue

When the correct source is selected, The monitor goes black for about 3 seconds, before turning off. It never shows any input

All of the settings on the monitor are grayed out, except System/PC/AV Mode and System/Display Port Ver.. This means the input is not being detected. Testing using my working monitor, those options become available when a source is plugged in.

I’ve read online that this issue can be caused by bulging capacitors, however I took the monitor apart and I don’t see any capacitors at all (unless they are onboard capacitors?):

#StackBounty: #display #resolution #xorg #xrandr #modeline An attempt to switch to a doublescan X11 modeline fails with "Configure…

Bounty: 50

I have a modern 1920x1200 LED display, capable of up to 96 kHz HorizSync, up to 76 Hz VertRefresh, and up to 205 MHz pixel clock.

Apart from its native resolution, the display can also run in 1600x1200 (4:3) resolution at 75 Hz:

  1600x1200 (0xa1) 202.500MHz +HSync +VSync
        h: width  1600 start 1664 end 1856 total 2160 skew    0 clock  93.75KHz
        v: height 1200 start 1201 end 1204 total 1250           clock  75.00Hz

Now, I’m trying to switch it to a 800x600 doublescan mode equivalent to the above 1600x1200 mode (at 75 Hz, too; all modelines taken from here):

xrandr --newmode "800x600d" 101.25 800 832 928 1080 600 600 602 625 DoubleScan +HSync +VSync
xrandr --addmode DP1 800x600d

The resulting video mode gets added successfully and is clearly visible in the output of xrandr:

  800x600d (0x1f7) 101.250MHz +HSync +VSync DoubleScan
        h: width   800 start  832 end  928 total 1080 skew    0 clock  93.75KHz
        v: height  600 start  600 end  602 total  625           clock  75.00Hz

But once I attempt to switch to the new mode, I immediately receive an error:

# Mode by name
$ xrandr --output DP1 --mode 800x600d
xrandr: cannot find mode 800x600d

# Mode by id
$ xrandr --output DP1 --mode 0x1f7
xrandr: Configure crtc 0 failed

Are modern graphics cards no longer able to run in a doublescan mode?
Or should I blame my display?

#StackBounty: #display #external-display Random "Alignment grids" on my monitor

Bounty: 100

I bought a new BenQ GW2480 monitor. When I quickly change images I get these random lines that look like "alignment grids"(in quotes because I don’t know how to refer to them — see image). For example, the Microsoft To Do app has these inbuilt wallpapers. When I quickly change between them (or change between different lists, which changes the wallpaper), I get these random lines that look like a grid.

enter image description here

Note that this problem is different from this, this or this in that this is completely random and goes away automatically if I change the screen. Further, they don’t always appear on the same area. This one is just two lines — sometimes I get a square or a grid at the bottom or top part alone (see second picture below). The other ones linked seem to be a permanent issue that is fixed when a particular monitor setting is changed. Also, in my case, the gridlines move when I move the window.
enter image description here

What’s happening and how do I fix it? Some more info: I have an Acer Swift 3 laptop, Core-i5 8250U, Intel UHD 620 graphics and the monitor is a BenQ GW2480. (Laptop & Monitor)
