I'm dealing with a tricky problem on QGroundControl, it doesn't show video source options when I'm connected to the UAV, and I have no idea how to make this show up.
Already tried reinstalling with the recommendations, installing Qt Creator, but nothing worked.
On "Application Settings", in "General" under "Fly View", you should be able to see a "Video Source" option below the "Video decode priority". Or, like this example below, there is a "Video" submenu. Mine does show when I'm disconnected, but when I connect to Px4 on my Gazebo simulation, the video source disappears and it shows on the main page "Waiting for video".

I have the same simulation running on a friend's computer and this option is showing.
Does anyone know how to solve this?
Perhaps it has something to do with Ubuntu 16 version?

This is a basic question that I hope has a simple solution. When I move my Rstudio window to an external monitor display - it no longer rescales properly and instead is rendered completely useless - showing me only the lower portion of the window (see screenshot) and doesn't allow me to resize the window or adjust it in anyway to access the taskbar along the top. Has anyone else experienced this or have options for how this could be fixed?
I frequently need to shift my Rstudio window to different monitors, and I was doing this with no issue prior to installing the latest Rstudio version - so I am wondering if there must just be some setting that got reset when I updated the software, but I can't seem to figure it out. I have tried fixing scaling options in Windows by using the properties options on the Rstudio icon on my desktop - and then clicking on compatibility and High DPI settings, but messing around with that so far hasn't seemed to work. However I haven't tried all possible combinations as i thought I would check here first to see if someone could fast track this process for me. As you can see in the image - this display is impossible to work with. When I move it back - it works as it should. I am using Windows 10, and I update my software regularly. TY!
Update
Ok, I was able to reproduce on a Lenovo with an external Dell monitor and address the problem by applying a fix proposed in another Stack Overflow thread. See below:
Research:
https://support.microsoft.com/en-us/topic/windows-scaling-issues-for-high-dpi-devices-508483cd-7c59-0d08-12b0-960b99aa347d
Resolution:
There is a solution, it comes from the option "Compatibility" of the execute file.
Close all current RStudio windows.
Right-click on the shortcut of RStudio (or the original .exe file) and choose Properties
In the RStudio Properties pop-up windows, choose the tab Compatibility
Select High DPI settings
Tick on option Override hide DPI scaling... and then choose System from the drop-down list.
Apply > OK.
(Re)open Rstudio to see the change
On my test system, this addressed the problem observed where the menu text became super large.
Stackoverflow original reference:
RStudio HiDPI support
This appears to be an issue with the version of QT used by RStudio. RStudio is built on top of the QT engine.
QT tracking Issue:
https://bugreports.qt.io/browse/QTBUG-48242
the issue is marked as fixed in QT version 5.9.0 and above.
Recommendation:
Download RStudio preview and try that:
https://www.rstudio.com/products/rstudio/download/preview/
Why? The preview version of RStudio appears to use QtWebEngine/5.12.8, which implies the issue is addressed. If that does not resolve the issue you could file a bug with RStudio, or install and recompile RStudio from the source with an updated version of QT. You can check your QT version via the help, about box.
Hoping the above points you in the right direction. Stays safe and well.
I'm taking the Data Science course on Coursera, the task is to share your notebook on IBM Watson Studio. I followed all the steps to generate the link but when I try to open it, it shows an empty notebook with one empty cell.
I tried to open on other browsers, private tabs.
Reached out to the staff on Coursera but nothing helpful, only got a screenshot of steps to follow which I did.
You need to save your notebook using "Save Version" menu option and not just "Save"
I am guessing that you didn't hit the "From URL" tab. Here's a screenshot.
I have a strange PROBLEM.
I installed Postman following the instructions from the Internet.
Now it can be opened, works fine etc. but icon is not displayed.
occupies a place, shows that it is open and it writes a name when it crosses over it but irritates me because it can not be seen. What is the problem and how can I fix it? I tried to reinstall it and same happened...
Sorry if this is the wrong place to answer but I found no other community which could help me with this. I accidentally closed the left-sidebar that shows the currently open project and it's files. Not sure what it's called, maybe navigation, folder view, either way, I tried pressing nearly every key combination to no results. I tried searching in the command palette for something that looked like "open project sidebar" but nothing. Now I'm stuck having no idea how to restore my primary navigation means when working with Atom. I tried opening multiple projects but I just get a black screen without the project sidebar, like it was hidden.
Any ideas?
I'm talking about this sidebar:
It is called "Tree-View".
You should be able to enable it via command pallete or ctrl + ,
It depends on your OS. On Mac OS X, it's CMD-\ (Command-Backslash) to toggle it. The option located on the View menu, called Toggle Tree View (the last menu option).
I recently updated RStudio for Windows via download link mainly due to interest in the new features of the most recent version 0.99.878. Unfortunaly after the installation some important hotkeys behave different in the source editor, while they still work in the Console. I.e.
Ctrl+S starts an "isearch"
Ctrl+V jumps to the end of the document
When I enter Ctrl+X+(S or V) the hotkeys work as they should. The hotkeys can be customized, however when I open the Keyboard Shortcuts dialog it shows me the settings for the hotkeys. Also the cursor has turned to a shiny green rectangle (insert isn't activated).
The problems remains after switching the project. Also reinstalling Rstudio 0.99.878 didn't work out. I've seen a similar issue here, but think mine is different as it is installation related. I might have accidentally activated a special editor setting but couldn't find any.
It sounds like you may have (accidentally?) activated Emacs keybindings. If you go to Tools -> Global Options..., you can reset the preference here:
