[Pkg-lxde-maintainers] Bug#656036: Possibly consistent recovery.

[Gordon Haverland]

lxpanel is still being a yoyo.

If on hovering over a virtual desktop, you don't get a small 
banner telling you what virtual desktop you are running, then 
lxpanel is hooped again.

Get to a shell, and do a listing with top.  lxpanel should be near 
the top, getting most of the CPU cycles.  Note the PID of lxpanel.

Quit top.  Try 'lxpanelctl restart'.  It probably won't work.  Use 
top again to see if lxpanel is still hogging the CPU.  If lxpanel 
still hooped, get out of top and send SIGHUP to the lxpanel 
program:
  kill -SIGHUP lxpanel_PID
where lxpanel_PID is the PID of the lxpanel process.  This causes 
lxpanel to die, and then a short time later, (usually) a new 
process is started (which still has a start application button).  
Top will show lxpanel behaving, and hover over a virtual desktop 
should give a banner again.  At this point, I am being paranoid 
and running lxpanelctl restart.  It has worked 3 times, the same 
every time.

What I suspect is causing lxpanel to go crazy, is moving the mouse 
while clicking a mouse button in lxpanel (or in my case, a 
trackball).  It might be just moving the mouse while clicking a 
mouse button in lots of places (not just the panel).  But I have 
no proof so far.  Just lots of times I need to restart lxpanel.
