It was fixed upstream. I'm not entirely sure whether 9.10 got this, but as VMware did not receive any further bug reports I guess it did. commit 31a5639623a487d6db996c8138c9e53fef2e2d91 Author: Daisuke Nishimura Date: Mon Sep 21 17:02:50 2009 -0700 mm: add_to_swap_cache() must not sleep

I had to reboot my box, so I've given theoretical Xsession.d code I described in #16 a try, and indeed setting it there does not work if you are using gnome-session, as for unknown reason gtk+2.0 refuses to pass variable down to applications it starts. So gnome-session itself uses native windows -

On command line, before starting X. If you are using gdm/kdm, adding file /etc/X11/Xsession.d/85fixsynergy with contents: # -*- sh -*- GDK_NATIVE_WINDOWS=true export GDK_NATIVE_WINDOWS could do the trick. Or - for one-time testing - you can do that in your xterm, and then kill & restart problem

And now when taskbar works I've noticed that problem is much more widespread: apparently all Gtk::Button instances are affected, so for example VMware Workstation user interface can be controlled only through menus - toolbars work like task list did, and buttons in summary do not work at all :-( -

Just in case you can reproduce this on any system which supports hibernate but does not support sleep. Responsible code is this: static void idle_do_sleep (GpmManager *manager) ... } else if (strcmp (action, ACTION_SUSPEND) == 0) { gpm_info_explain_reason (manager->priv->i

Ah, none of Ubuntu kernels is built with CONFIG_PREEMPT=y - only with PREEMPT_NONE or PREEMPT_VOLUNTARY. That explains why thread above never runs, as there is no cond_resched() in a read_swap_cache_async() loop mentioned above. -- Kernel hang under memory stress https://bugs.launchpad.net/bugs/
