Build Identifier: M20100211-1343

OS: Ubuntu 10.4
After the screensaver kicks in, Eclipse does not react on keyboard input anymore.
This is applicable for every editor in Eclipse.
After the Eclipse window is minimized and restored again, keyboard input works as expected again.

Screensaver preferences: Blank, 5 Minutes, Activate wehen Idle, Lock screen when active. 

Reproducible: Always

Steps to Reproduce:
1. Start Eclipse
2. Open a project file in the text editor
3. Wait for the screensaver
4. Unlock the screensaver with password of user logged in
5. Try to edit....

Is this specific to eclipse or the system itself is not responsive in general ? Also, you mention editors; is it a problem with editors only while the other parts of eclipse respond to keyboard input ? 

Please do provide other details like whether this happens consistently / frequently on your system or if you noticed anything in the logs, etc.

Need info to move this bug further; marking as WORKSFORME for the time being.

This is specific to Eclipse.
The rest of Ubuntu is responsive as usual.
This only happens when an editor window has the cursor focus.
It only seems to affect the editor.

Normal editing is possible again after either
- editing somewhere else in Eclipse (f.e. a find/replace dialog box)
- minimizing and maximizing the Eclipse window
- any other window gets the focus

It does happen often but after some testing I must conclude that it does not happen every time.

I did the reopen the ticket, was I supposed to do this?

Are you using Compiz? Can you try using Metacity instead?
Comment 6 Gerben Blom CLA 2010-11-15 18:44:42 EST 
Hi Remy,

Switched to Metacity and could not reproduce the problem. Switched back to Compiz and it did occur again. Switched back to Metacity, no problem.
Definitely something to do with Compiz.

Gerben.

Thanks for the information, Gerben.
