问题 I have a selenium test which I am trying to run Headlessly on my ubuntu server. It uses pyvirtualdisplay and xephyr. Though the script is running fine in my local system, it hangs when I run it in the server. I have tried to clear memory and restarting the server. But no luck. The script looks something like this : from selenium import webdriver from pyvirtualdisplay import Display display = Display(visible=0, size=(1366, 768)) display.start() driver = webdriver.Firefox() driver.set_window

问题 I'm looking to automate deploying content via RDP. The current setup involves manually RDPing to the machine, copying the file to it, and moving it into place. Once on the remote machine, I can easily script massaging the content into place, but how do I script establishing the RDP session and kicking off the remote script? 回答1: It appears that Remote Desktop can only be used interatively. Powershell Remoting seems to accomplish the goal though. 来源： https://stackoverflow.com/questions

问题 I am currently using PDE build in headless mode to build my OSGI Bundle project. The PDE Antrunner task uses an Eclipse installation and I am just pointing it to my local Eclipse installation. unfortunatelly my eclipse installation is about 260MB big, but I assume that a PDE build does NOT require all of those plugins in a standard eclipse installation. Does anyone now what is the minimum list of plugins I need for doing a headless PDE build? All of my dependencies I actually have in a custom

问题 I have a headless UWP app that is supposed to get data from a sensor every 10 minutes and send it to the cloud. When I run the code from the headless app on the Raspberry Pi it stops measuring after 3 or 4 hours, no error (I have a lot of logs). It is exactly 3 or 4 hours. If I start the app at 8, at 11 or 12 it just stops... It looks like it is stopped because I have cancellation token in place that worked well in tests, but here it is not firing anymore.
