Atom doesnt work on Ubuntu on Wayland - atom-editor

I’m using Ubuntu on Wayland because of other apps, which doesn’t work on ubuntu, But when i start atom (even form menu or from terminal) the system suspends, and i have to log in again. In normal Ubuntu it works perfectly. Do you know the solution? I tried to reinstall atom, and instaled libgconf-2-4 as was suggested, but did not work.
Thank you

Launch rstudio-server from terminal linux

I'm an Ubuntu user and I used to work with the standard version of Rstudio on my computer. After reading about the server version I installed it on my PC and I'm working with it now. Although I'm very happy with rstudio-server version, I have been facing some difficulties to keep with some old practices. Particularly, I use to launch, open and create new files from the terminal using rstudio keyword - I'm specially fond to the possibility of open files in current rstudio session through the terminal window within rstudio. However, I cannot figure out which command is equivalent in rstudio-server.
I tried, without success, the following commands:
rstudio-server
and
r-server
Interestingly, when I type which rstudio (to find the path of the program's binary files), the terminal did not return any results. The program is installed and working normally, but I just can't find it on my PC
Any help will be appreciated

What can I change if the turtle-code logs me out of python 3 Jupyter?

If I run this Code on Python3 (Anaconda Jupyter 6.0.0) I'm getting logged out automatically. I use a Mac with macOS Mojave.
The code is from the book "How to think like a Computer Scientist". So I'm at the beginning to learn some python.
I already tried to delete the turtle.py files in the library, but it didn't work either.
import turtle
window = turtle.Screen()
alex = turtle.Turtle()
alex.forward(50)
alex.left(90)
alex.forward(30)
window.mainloop()
When I run the code I get logged out. When I log in again, Jupyter just shows a window with "error".
This is more a by-pass than an answer as I am still trying to figure it out myself. I have a macbook and am experiencing the same behavior with PyCharm and Anaconda.
If you want to learn python, the code above runs fine if you instead install the base python interpreter from https://www.python.org/. It includes the turtle module and you can change it in your IDE so that this new interpreter is the default rather than Anaconda. If I figure it out what is happening with Anaconda before someone else, I will let you know.

Multiple versions of R installed but can't locate or remove the old one

I have downloaded and installed R.
I see it here in Applications folder (I am on a Mac with Yosemite):
Fine. I can launch R.app and indeed, yes, I am running the version I want, which is 3.2.2:
So far so good. I can even open up RStudio and see that I am indeed running 3.2.2!
So after all this, I simply go to my terminal, type
r
and turns out I am running 3.1.1!
I understand the old user of my work computer probably had installed this older version.
So here's what I'm wondering:
If I just installed R.app correctly, WHY is this old version still living on my computer, and how do I get rid of it?
If this is some sort of $PATH thing, WHY doesn't the most obvious location for an app, the Applications folder, get checked for the existence of R?
Thanks.
UPDATE
Turns out the old version of R has been installed by homebrew.
Typing which r in your terminal will give you where the shell thinks R is. Then, you need only uninstall it from that location.
Since we've determined it's homebrew, all you need to do now is brew unlink r; rm -Rf /usr/local/Cellar/r/3.1.1 and you should be golden after you rehash in your shell.
It worked because you installed it using homebrew. To remove it from the system, you must first unlink it and then remove it from the system.

RStudio empty on startup - No windows, no menus, no rendering

When I start RStudio, none of the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
It feels like some kind of graphics rendering or window management problem.
I'm running Windows 7. I have the latest version of R, which is 3.1.1. I have the latest RStudio, which is 98.1062.
How to fix it?
Reset the RStudio state. Do this:
Close RStudio if open.
Go to this directory: %localappdata%\RStudio-Desktop
Rename that directory as a type of backup.
Start RStudio.
RStudio will see the configuration directory is missing and regenerate it with correct values.
Everything should work after that.
Other threads I found helpful here are:

Thanks!
Renaming the RStudio state by renaming %localappdata%\RStudio-Desktop did not work for me. However i made it work by renaming another config folder in %appdata% instead.
Close RStudio
Go to this directory: %appdata%\RStudio
Rename the folder
Restart RStudio
I faced the same issue when I downgraded my version of R.
I did try the above solutions. However, it didn't work for me.
After some googling, I found out that the issue was because now I had a different version of R installed. Here's how you can choose the version of R and rectify the issue.
Navigate to the RStudio installation folder. (C:\Program Files\RStudio\bin)
Press and hold Control Key
Double click on rstudio.exe
Choose a specific version of R (whichever you want to work with)
Click OK and RStudio should open without any issues.
NB: I use 64bit Windows 8.1.
I had the same issue and I almost gave up about solving it but then I found a suggestion that GitHub might be the problem. I am not sure how that is happening but the minute I uninstalled GitHub and re-launched Rstudio, it worked perfectly as nothing happened!? Here is the link for where I found the suggestion on Rstudio community page: (https://support.rstudio.com/hc/communities/public/questions/200983187-R-studio-0-98-797-for-mac-opens-as-blank-white-page)
I had the same problem and figured out that for some reason R was blocked on the step of loading my library from a website (I added it to Rprofile for auto-load). You can test the following:
1) Try to run just R console, not RStudio, and then click on blank space - normally some information should appear
2) Try to launch without network connection
On a Mac (Running Yosemite 10.10.3) this is what worked for me:
Move/Rename ~/.rstudio-desktop
(Many responses have mentioned this, but this by itself didn't help.)
Then I shutdown my Mac and restarted it. RStudio worked when I logged back in.
Before that, I tried every one of the steps mentioned here and in many other links, including re-downloading R and RStudio, but unfortunately none of those steps helped in my case.
Search this documentation for 'Blank GUI'.
This is what I found which worked for me:
In Windows Explorer, go to C:\Users\currentUser\AppData\Roaming\RStudio.
Delete the Desktop.ini file
This technique forces RStudio to refresh and default to open-source R as the engine
Same issue I faced so I unistalled the windows installer and downloaded zip version from this link https://www.rstudio.com/products/rstudio/download/
Unziped It and pasted it into c drive and created shortcut from Rstudio/bin/rstudio.exe file.
Working properly after that no issue. In windows installer checked that r session is not working due to an missing dll.
So try to install from ZIP
I had the same problem like Thomas
When I start RStudio, none on the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
My problem was, that i uninstalled R because is thought RStudio will work on its own.
So i uninstalled RStudio and deleting every existing file which was created by R or RStudio.
In the next step i installed RStudio again.
It was asking for a Version of R (which i dont had in this state). So i installed R again and everything is working fine now. I hope this helps
I had a slight variation of the problem that might be of interest. I had set up an aliases.cmd to run my cygwin bash shell automatically upon launch of a cmd terminal as per:
https://superuser.com/questions/302194/automatically-executing-commands-when-a-command-prompt-is-opened
What RStudio was doing was launching a few cmd windows in the background to (I assume) populate each pane and the console.
This was triggering a bash shell which wasn't returning and was hanging RStudio.
If you have this issue you can just manually kill the sub bash terminals spawned by cmd via ProcessExplorer/TaskManager and RStudio will continue to launch normally.
If anyone else has set anything to launch automatically on init of a cmd terminal then this could interfere in the same way with RStudio.
The RStudio devs could probably fix this behind the scenes by changing the way they spawn cmd terminals in the gui.
I had a similar problem. After trying the options above with no luck, I uninstalled Rx64 3.5.0 and installed an older version, R x64 3.2.2.
Rstudio then worked perfect.

RStudio is blank when opened

I have just installed the latest versions of R (3.1.0) and Rstudio (v0.98.507) on a Windows 7 machine, 64 bit.
The R GUI works OK, but when I open the RStudio.exe only a blank window opens. I've tried re-installing R and RStudio.
Any suggestions?
By choosing the R version I wanted to use I was able to use Rstudio again.
To choose the R version you want to use with Rstudio do the following;
Click the CTRL key (don't let go)
Click on the Rstudio icon
Choose the version you want in the pop-up window.
For Ubuntu users where #neal's solution doesn't work.
$ rstudio --no-sandbox
related to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1944468
Download the 64bit version and reinstall it.
The same for Linux
FOR LINUX: this happens to me on cloud instances. A solution is forcing software rendering of RStudio. You need to start RStudio, get to the black screen, close Rstudio black screen, do my solution below in the terminal with Rstudio closed, then start Rstudio again.
In terminal:
sudo nano ~/.config/RStudio/desktop.ini
APPEND THE FOLLWING TO [General] section (leave whatever is there and add the line below):
[General]
desktop.renderingEngine=software
Again this is for Linux, but there may be a similar issue in Windows and you may be able to force software rendering.
Press down Ctrl key and then click on RStudio icon to launch. A dialog box asks you about the R version. Choose the one that actually exists (you might see an R version which does not exist; confusing RStudio)
For Windows10 64bit.
After following the hold Ctrl and clicking RStudio icon.
Change the Rendering Engine: to Software.
This fixed the problem on my machine.
