Bug 155243

After a reboot, and possibly upgrading some packages, but not the software mentioned before, I had the following experience:

Launched a bare X server, running only a terminal. Within the terminal, run a handful of commands, including using the mouse to copy-paste. Then run 

    SAL_USE_VCLPLUGIN=gen soffice --writer

The following 2 lines were printed to the terminal:

    javaldx: Could not find a Java Runtime Environment!
    Warning: failed to read path from javaldx

And writer started fine. Blinking cursor, Ctrl+f fully working. But after quitting writer the terminal was completely unresponsive. Both the keyboard, and the mouse, were unresponsive. And the terminal cursor was an blanked rectangle. I had to kill the X environment from another VT.
After restarting X, this time with a window manager, things got back to what they used to be. Including the documents that are opened by writer without a blinking cursor, and without a response from Ctrl+f. Though it looks like not only a mouse click brings things back to their normal working order, but also pressing the down arrow key.

Thank you for reporting the bug. Have you tried it with a clean user profile? If not, could you please reset your Libreoffice profile (https://wiki.documentfoundation.org/UserProfile) and re-test?

Is it only a problem with writer or also with other modules?

My understanding is that I should have a blinking cursor when I open a writer document. And not having such a cursor is a bug. 

I
1. Closed any the LibreOffice application I had open.
2. Used the [Quick test for corrupted profiles: use a temporary, new user profile](https://wiki.documentfoundation.org/UserProfile) 
    
     soffice -env:UserInstallation=file:///tmp/test

   The terminal had 

   javaldx: Could not find a Java Runtime Environment!
   Warning: failed to read path from javaldx

   and I got LibreOffice welcome screen.

3. File -> New -> Text Document 

   gave me a writer screen, with a blinking cursor, and a tip of the day. I confirmed, OK, the tip.
   Blinking cursor still on the empty document. There was also a message, with a blue background before the empty document, I am using LibreOffice 7.5 for the first time. Would I like to learn what's new?

4. I inserted the letter a in the empty document, and exited LibreOffice, saving a.odt to /tmp/. I then noticed there is also a terminal message

(soffice:21828): Gtk-WARNING **: 22:47:10.191: Could not init tracker3 search engine: The name org.freedesktop.Tracker3.Miner.Files was not provided by any .service files

5. Next I rerun soffice -env:UserInstallation=file:///tmp/test. Got, again

   javaldx: Could not find a Java Runtime Environment!
   Warning: failed to read path from javaldx

and a LibreOffice opening screen, suggesting a small screen shot of the a document.

6. By clicking the a document small screen shot with the mouse, I got it opened. Without a blinking cursor. The alt+letter keystroke did opened the suitable menu. In the Edit menu, the Find... was grayed. But I still had no blinking cursor at the body of the document. As usual, I had to click the mouse in order to get the blinking cursor.

As for other applications from the LibreOffice suite, I am only actually using calc. I am not sure what is the expected calc behavior. Doing a similar test with a new spreadsheet, the A1 cell has blue borders, but no blinking cursor can be seen. Inserting a at A1 and exiting by saving /tmp/a.ods. Not sure If I had to somehow re-select the A1 cell before I could insert a into it. Rerunning LibreOffic now has a small screen shots of a.ods and a.odt. Choosing a.ods open it. The A1 cell has blue borders, but no cell is active. Striking the keyboard b key does not seem to do something. That looks to me similar broken behavior on the side of calc.
