hyper v – Need help setting up an active RDP session

In my office, I am facing a problem, I hope someone can help me with that.

We have a Hyper-V server: deployed in an 8-node cluster.

Our test team runs an automation script based on the user interface (requiring a display resolution of 1920 × 1080 and an active RDP session).

The problem is

1) Hyper-V does not support 1920 × 1080 display resolution and can only support up to 1600 × 1200.

2) If I use RDP, I get a resolution of 1920 × 1080 but if I disconnect the RDP session, the script execution fails. So, I used a "tscon" powershell script and a scheduled task in the Windows Task Scheduler to trigger the script when logging out of RDP.

The script keeps the RDP session active, but as soon as RDP disconnects, the resolution returns to 1600 × 1200 and the UI automation script fails.

Tried to use VNC but no luck because it uses the Hyper-V display resolution …

Is there a way to solve this problem?

Setting group permissions

I have a lot of users and two groups. Some of them are members of group1 and others are members of group2. I want to allow group 1 to access all directories and group 2 to access specific directories. I did some research but I could not fix it. How can I do that?

Thank you.

windows 10 – Driver failure randomly when setting up a dual monitor

I have recently built a new PC, the main specifications are as follows:

  • Z390 motherboard.
  • Intel 9900k processor, OC at 5 Ghz.
  • GPU RTX 2080 Ti, stock settings.
  • 64 GB of DDR4 3200 RAM.
  • 750W power supply.
  • Two monitors, both 27 "4k, one of them supports HDR, both connected to the GPU using a 1.2 DP cable.
  • A clean Windows 10 Pro (1903) installed, with all the latest patches installed.
  • Installed Geforce WHQL 431.60 driver, using all default settings.

In most cases, the system works well and smoothly. But there seems to be a problem with the GPU / driver / monitor settings that I could not understand.
The symptom is that a black screen suddenly appears on both screens, and then the system seems to have a hard time tipping back and forcing between the actual image and the black screen for 5 to 8 seconds. After that, either it will recover itself without any error message or warning on the screen, or it will completely quit, causing the two monitors to shut down by themselves as no signal is available. entry was not detected. In this last scenario, the PC still seems to be running because the sound is still playing. But it is not possible to restore the display of the image unless you make a sudden restart.
The behavior seems a little random for me until I finally find a reliable way to reproduce the problem:

  1. Enable the "Play HDR Games or Applications" option in the main monitor window settings (the one that supports HDR technology).
  2. Open any window or task on the main monitor (browse window, browser window, empty Word file or game)
  3. Open Chrome on the other monitor, go to Youtube and watch any video.

Now, as soon as I put the video playback in full window mode. the problem occurs with in the next 3 seconds guaranteed. In the Windows event log, an entry says "nvlddmkm has stopped responding and has been successfully recovered."

That being said, I googled it and found a workaround for that specific problem. The fix is ​​to disable hardware acceleration in Chrome. I have tried this and it works. But that did not solve the problem of the black screen completely, but simply eliminated one way of causing this problem.

Another interesting observation is once I've disabled the HDR in Windows for my main monitor, while still maintaining hardware acceleration in Chrome, and then testing again in the same scenario, the problem can still occur produce. But that does not happen all the time. More likely under a random base, 4 times out of 10, at one time or another. But once this happens once, it will happen every time after that, until the PC can not recover on its own and perform a brutal reboot.

The only way that seems to completely solve the problem (at least I have not experienced any failure so far), is to get rid of a monitor .. no matter which one. If only one monitor is connected to the GPU (via any DP port), the problem seems to never occur. But subconsciously, I can not live with the fact that a RTX 2080 Ti is unable to power 2 monitors 4k.

FYI: I have tried several DP cables, that does not help me. And I can not use HDMI cable because some can only get a refresh rate of 30hz on 4k if I connect them with an HDMI cable.

FYI 2: I tried to go back to an earlier version of the driver, it does not help.

Does anyone know what could be the problem here? It has been bothering me for days and I did not even know what part had gone wrong, let alone fix it. Any help / comments / suggestions will be very appreciated!

nikon – Photos are almost black when you use the aperture setting. Works well in automatic mode

Your publication is usually devoid of usable information, such as Model, Flash and Speedlight camera settings, an image including EXIF ​​data, and so on. However, let me focus on two sentences triggering my sensor "I've seen it quite often":

My images are almost black with the aperture setting set in my Nikon D3100. Works well in automatic adjustment. Using a speed light that turns off (the speed light is working well)

What I've experienced over and over again is a slow flash that does not seem appropriate between the pre-flash and the main flash. The result is that the camera triggers its pre-flash measurement, calculates the appropriate flash exposure from it, and then creates the actual photograph with such a short delay that the flash n & # 39; 39 is not ready to emit the main flash.

The result is that you only see one flash (instead of two) and it happens before the picture is taken. "Almost black" is an almost infallible indication of this. If this is not the case in your photo, the light distribution of the almost black image will always correspond to what you would expect from a light source near the camera: barely visible shadows (or not at all) slightly below the objects (assuming flash above the lens). If the shadows of almost black images are different, it means that the flash was not active during the actual exposure time.

What does the ISO setting actually do for 35mm cameras?

I wonder if the ISO setting affects the aperture or if some shutter speeds are no longer usable?

mysql – Error while setting up the database after importing products into woocommerce

I'm trying to download more than 1500 products on my site using CSV and import them via woocommerce. I met him a few days ago when I tried to download the total of 1500 products on my site. After about 5 minutes, the importer stops and I can not access my sites for about 20 minutes, even the /wp-admmin/maint/repair.php – but I did it shortly thereafter and I managed to fix it. Now I decided to try to download only 200 products at a time using the woocommerce importer. But again, after the second batch of downloads, I get the same error again.

Can someone help me with that? Or advice on how I can import my products without having this error? Thank you

ffmpeg – Setting (rather than resampling) audio in a video file

I have recorded a live stream with OBS and my audio sampling frequency has been set to 44.1 KHz. Unfortunately, OBS has interpreted the audio input of my device as being 48 KHz. So there are a lot of problems and the audio is set at about 9% higher (which was the case during the stream itself, although no viewers realized that this was happening at the time.).

Is there a way to use FFMpeg or similar to change the audio stream sample rate (and probably remux), without trying to resample the audio?
