#9154: Crashes when lyx window comes into focus with sloppy mouse focus.

[Eddie Rucker]

I'm using ubuntu 14.04 LTS with the default memory manager unity. I used the unity-tweak-tool to set the workspace settings - choose the Additional tab and set Focus mode to sloppy.

Comment (by skostysh):

How do you set this in Ubuntu? Are you using the default window manager?
Unity or Gnome classic? Which Ubuntu version?

Thanks a lot for the quick reply and additional details, Eddie. I will
take a look at this and see if I can reproduce it. Next time, please
respond on the trac website so that we have all of the info in one
place. I pasted your response in there this time.

Best,

Scott

Hi Scott.

I think I have found the issue. But, first,

Eddie, how did you install 2.0.7 on your machine?

I uninstalled 2.0.7

Did you compile manually?

Yes.

You might consider trying LyX 2.2.dev from the daily PPA. For instructions,
see here: http://wiki.lyx.org/LyX/LyXOnUbuntu#toc3

Thanks Scott I will definitely go this route.

Do you still see the issue?

Yes.

However, I am pretty sure the bug is in the particular mouse hardware or in the mouse driver used for this particular USB mouse because:
(1) LyX does NOT crash when I just use the mouse pad on the school's Lenovo T430 notebook. It only crashes when I plug in the USB mouse and use it. When I unplug the mouse the problem goes away again.
(2) When using the USB mouse, Emacs 2.4 freezes as I pull the mouse over its window. I have to use kill to get rid of the emacs process. No other application programs I've tried seem to be affected.
(3) I got another external mouse from school this morning and it works fine.

Sorry about this. I should have tried all this before I filed the bug report. Thanks again for the LyX2.2.dev instructions!

No problem. Hardware issues, software incompatibilities, etc, can be
hard to debug.

I agree. No need to apologize. And as for "should have tried it
before", I personally wouldn't have realized to check that. I have
never seen a faulty mouse driver in my decade of Linux use, and
certainly not one that causes a crash.

Thanks for the bug report, the follow-ups, and all of the details.
Please don't feel hesitant to give us more feedback on bugs or feature
requests. I'd rather err on the side of too many reports with a few
false positives than too few with some bugs that go unreported.

Best,

Scott

Thanks Richard and Scott! It was the mouse. When I plug the mouse into a Windows machine, it constantly connects and disconnects.
