idea not open the main windows when run idea.sh

The log shows that the IDE has been initialized.

Do you have several monitors, could it be that the IDE window is displayed off-screen or on a different monitor/work-space?

Do you see the IDE window if you launch IDE not via .sh file?

>then I try to delete ~/.IdeaIC2018.3 and ~/.local/share/jetbrain and reinstall the idea,

Make sure you are deleting the configuration files for the right IDE version: the log is from IdeaIC2018.1 version but with the `~/.IdeaIC2018.3`  you are referring to 2018.3.X version.

I had several monitors but all can't see any window. use .sh and .desktop file both not working. I try install the ultimate version.  the start window  quickly disappear after display 0.2 second when I run the idea. is their any information you need I can take to you? 

So the process exits shortly after you launch it? What output is printed in console when you launch it from .sh file? Provide the output from terminal and idea.log file content.

I see the process always running on the background, but the UI was exits shortly after I launch it. there was no output from terminal, idea.log was:

here is the screen shot. I only use monitor 1, and monitor 2-9 didn't had any windows and application.

Do you see the the IDE in the list of applications when using OS application switcher? Do you see the application icon in the taskbar?

Try to set latest installed 1.8 Oracle JDK for the IDE JDK to run under: https://intellij-support.jetbrains.com/hc/en-us/articles/206544879.

Hi,

I have the exact same problem running the ultimate edition ideaIU-2018.2.6 on Ubuntu 16.04.

Since two days ago, I can't start the ide anymore. The tip window is does show, but no main window ever shows.

I can see the app in the application tool bar but there is no main window.

I've tried running older versions on the system, but same problem.

Rebooting the system did not help either.

Any advice how to get back to a working version of Intellij would be appreciated.

Try to move/rename IDE folders to start with all the defaults: https://intellij-support.jetbrains.com/hc/articles/206544519.

If the issue persists, start from the terminal and get the thread dump: https://intellij-support.jetbrains.com/hc/articles/206544899. Share the dump per https://intellij-support.jetbrains.com/hc/articles/206869619.

Hello,

just happened for me with IntelliJ version IC-192.6817.14 under Debian (KDE)

Looks like on first time start following happen:

1. The splash screen is opened

2. The User Agreement window appear somewhere, but is not focused and not displayed in task bar. Only way if going through list of opened windows with ALT+TAB it is possible to find the window.

As result looks like the Idea starts, the process running, but UI is not displayed (the User Agreement window is not displayed)

https://youtrack.jetbrains.com/issue/IDEA-191550 looks related.

Thank you for link to issue.
