[Bug 479641] Re: when memory runs low, xorg locks up and does not unlock when memory conditions improve

 

** Description changed:

  Binary package hint: xorg
  
  When I run low on memory, say, 20k or so remaining, xorg locks up
  (doesn't respond to input at all, incl mouse movements/capslock).   OK
  that makes sense...but the problem is that once memory situation
  improves (say, by me sshing from another computer to kill the process
  that's taking up the memory, whether it be firefox, gnu electric, or
  whathaveyou), xorg remains locked up, even if reniced to a more realtime
  priority.  It remains at 0% cpu usage, too, even while the system is
  idle and I am giving it input via mouse/touchscreen.
  
  Unlike the other reports on the intel drivers, Xorg is not using a
  disproportionate amount of memory -- the amount of memory used is fine,
  it is just not adjusting to memory conditions on the system.
  
  Ubuntu Karmic / evtouch touchscreen / intel drivers probably from below
  
  (also apologies that the attachments that were supposed to go towards
  this bug report went to the last one -- had i known it was going to
  attach all that stuff I would have just used the launchpad interface :)
  )
