[Bug 894470] Re: eclipse36 hangs, keyboard disabled EXCEPT for the SUPER key, mouse movable but no clicks processed

 

Yes, I also use nvidia on my PC, GeForce 6200 TurboCache(TM)/PCI/SSE2 
AMD Athlon(tm) 64 X2 Dual Core Processor 5400+ × 2
I use the current proprietary driver, and there are no related segfault entries in my dmesg log except for these two lines

[978093.888391] compiz[29704]: segfault at 48 ip 00007fd8dad1d4d0 sp 00007fff012e3dc8 error 4 in libcomposite.so[7fd8dad0f000+18000]
[978095.383527] compiz[29748]: segfault at 48 ip 00007eff42dd24d0 sp 00007fffaa22db68 error 4 in libcomposite.so[7eff42dc4000+18000]

I don't remember if the timestamp value matches the last time of
reappearence of the bug. I don't have the time now  to gather more
system-information data about driver, libs etc.

Title:
  eclipse36 hangs, keyboard disabled EXCEPT for the SUPER key, mouse
  movable but no clicks processed

Status in “openjdk-6” package in Ubuntu:
  Confirmed

Bug description:
  I have an old (German) (Windows)  PS-2 keyboard.  
  My oneiric is a fresh install, but I have restored a lot of my data files (and some config files in /etc) from a backup which was from an older oneiric, upgraded from natty. 

  When I work with eclipse36 for a while in oneiric under unity,
  eclipse 36 helios (from 2010) suddenly hangs.

  Then, all keys on my keyboard are disabled EXCEPT for the SUPER (Windows) key. When I press it, the Dash shows up and gets the focus. 
  When I press SUPER again, eclipse gets the focus (the frame-colors of some panel in the IDE briefly flashes)

  The mouse is movable but no clicks are getting processed.

  Ctrl Alt-F2 does not work. Removing the keyboard and plugging it back
  in does not work.

  I have to go to another computer, login to the hanging computer with
  ssh (works fine), then kill eclipse. Then, mouse and keyboard are
  usable again.

  Besides, and maybe unrelated to the above-mentioned- bug, sometimes
  eclipse crashes. There is no Eclipse crash dialog box with  process
  metadata.
