Ivan, I think I remember trying the key combo on my netbook and laptop and neither worked, so I don't this it's related to grabbing.
Well, good news (I think). On my Toshiba Satellite L655, I pulled up "/var/log/Xorg.0.log", and I seem to have found some source of the error for this. Here are the last few lines of the file: [343696.707] BUG: triggered 'if (priv->num_active_touches > priv->num_slots)' BUG: ../../src/synaptics.c:3123 in UpdateTouchState() [343696.707] Backtrace: [343696.707] 0: /usr/bin/X (xorg_backtrace+0x26) [0x7f5de0450886] [343696.707] 1: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5dda013000+0x2db0) [0x7f5dda015db0] [343696.707] 2: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5dda013000+0x364f) [0x7f5dda01664f] [343696.707] 3: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5dda013000+0x61b0) [0x7f5dda0191b0] [343696.707] 4: /usr/bin/X (0x7f5de02c8000+0x8af37) [0x7f5de0352f37] [343696.707] 5: /usr/bin/X (0x7f5de02c8000+0xb0d2a) [0x7f5de0378d2a] [343696.707] 6: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f5ddf5ee000+0xfcb0) [0x7f5ddf5fdcb0] [343696.707] 7: /lib/x86_64-linux-gnu/libc.so.6 (__select+0x13) [0x7f5dde54b003] [343696.708] 8: /usr/bin/X (WaitForSomething+0x19b) [0x7f5de044dc6b] [343696.708] 9: /usr/bin/X (0x7f5de02c8000+0x4e5f2) [0x7f5de03165f2] [343696.708] 10: /usr/bin/X (0x7f5de02c8000+0x3d7ba) [0x7f5de03057ba] [343696.708] 11: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xed) [0x7f5dde47f76d] [343696.730] 12: /usr/bin/X (0x7f5de02c8000+0x3daad) [0x7f5de0305aad] [343707.298] (II) AIGLX: Suspending AIGLX clients for VT switch To me, it looks like a stacktrace dump, and it clearly says "BUG" at the top, referring to the file src/synaptics.c, somewhere in Xorg. Frankly, I have no idea how to interpret the condition in the "if" statement. So, I think this is clearly a bug in Xorg, but I don't really know how to fix this. :( -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/830099 Title: Mouse stopped moving - touchpad still responds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/830099/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
