Cannot find “valid home for jdk” in intellij idea












2















I'm trying to setup an SDK for intellij idea and I can't find the home for jdk as the error put it.



In the terminal this is what I get



$ java -version

openjdk version "9-internal"

OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)

OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)


I tried to run



$ whereis java



and none of the paths are valid



then I found the jvm folder in usr/lib/jvm none of those worked either.



this is the output of



$ ls -lh /usr/lib/jvm/



enter image description here



I just ran another command 



$ update-alternatives --list java


Output was 



/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

/usr/lib/jvm/java-9-openjdk-amd64/bin/java


In idea, the sdk selector will only go upto the /bin but the internal files don't appear and in the file explorer I can see the java file but clicking it does nothing nor can I directly copy it's path as I get the error:



"Specified path cannot be found"



Also ran 



$ sudo update-alternatives --display java


Output 



java - auto mode

link best version is /usr/lib/jvm/java-9-openjdk-amd64/bin/java

link currently points to /usr/lib/jvm/java-9-openjdk-amd64/bin/java

Mouse cursor on multiple screens with different PPI

Image
24 6 I'm using a 4K display along with a Full HD display with both almost the same physical size and it brings some mouse cursor problems to me working with it on the default Windows settings. As the mouse movement speed depends on the pixels, it's very slow on the 4K display and very fast on the Full HD display. Is there a windows setting or application to move the mouse depending on the visible distance and not the pixels? Another problem is the virtual wall between the screens I can't move the cursor from the upper half of the 4K screen to the Full HD screen: How is it possible to virtually stretch the cursor transition area of the Full HD screen to the one of the 4K monitor? The smallest problem, nevertheless painful, is the cursor size which varies between the screens. Is there a way ...
