I notice this in your XorgLog: [ 5994.912] (EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Invalid argument.
Subsequent to that it re-acquires the touchpad (and monitor, and usb mouse): [ 5995.208] (--) SynPS/2 Synaptics TouchPad: touchpad found Working theory... the power adapter causes a gpu lockup that the kernel recovers from, but X doesn't reload the touchpad settings and thus misses a quirk/workaround for the jumpy cursor. Can you test this theory, by booting fresh on battery, then running 'tail -f /var/log/Xorg.0.log' in a window, and plug in your power adapter. If the theory is true, the batch buffer error message should print out, and then the touchpad should start behaving weird. ** Description changed: Binary package hint: xserver-xorg-input-synaptics I'm in Israel right now and I have my adapter set up properly with my laptop, but the touchpad is flipping out. Cursor jumps randomly and clicks even when I haven't clicked. My USB mouse is not affected and the problem with the touchpad disappears once unplugged. + + [ 16.288] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/event8) + [ 16.288] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall" + [ 16.288] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall" + [ 16.288] (II) LoadModule: "synaptics" + [ 16.288] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so + [ 16.300] (II) Module synaptics: vendor="X.Org Foundation" + [ 16.300] compiled for 1.9.0.902, module version = 1.2.2 + [ 16.300] Module class: X.Org XInput Driver + [ 16.300] ABI class: X.Org XInput driver, version 11.0 + [ 16.300] (II) Synaptics touchpad driver version 1.2.2 + [ 16.301] (**) Option "Device" "/dev/input/event8" + [ 16.308] (II) SynPS/2 Synaptics TouchPad: x-axis range 1472 - 5472 + [ 16.308] (II) SynPS/2 Synaptics TouchPad: y-axis range 1408 - 4448 + [ 16.308] (II) SynPS/2 Synaptics TouchPad: pressure range 0 - 255 + [ 16.308] (II) SynPS/2 Synaptics TouchPad: finger width range 0 - 15 + [ 16.308] (II) SynPS/2 Synaptics TouchPad: buttons: left right + [ 16.312] (--) SynPS/2 Synaptics TouchPad: touchpad found + [ 16.312] (**) SynPS/2 Synaptics TouchPad: always reports core events + [ 16.316] (II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad" (type: TOUCHPAD) + [ 16.316] (**) SynPS/2 Synaptics TouchPad: (accel) keeping acceleration scheme 1 + [ 16.316] (**) SynPS/2 Synaptics TouchPad: (accel) acceleration profile 0 + [ 16.316] (**) SynPS/2 Synaptics TouchPad: (accel) acceleration factor: 2.000 + [ 16.316] (**) SynPS/2 Synaptics TouchPad: (accel) acceleration threshold: 4 + [ 16.324] (--) SynPS/2 Synaptics TouchPad: touchpad found + [ 16.324] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/mouse1) + + ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: xserver-xorg-input-synaptics 1.2.2-2ubuntu7 ProcVersionSignature: Ubuntu 2.6.37-12.26-genusername 2.6.37 Uname: Linux 2.6.37-12-generic i686 Architecture: i386 CompisitorRunning: None CompizPlugins: No value set for `/apps/compiz-1/general/allscreens/options/active_plugins' DRM.card0.LVDS.1: - status: connected - enabled: enabled - dpms: On - modes: 1440x900 - edid-base64: AP///////wBMo1dEAAAAAAAQAQOAHhN4Cof1lFdPjCcnUFQAAAABAQEBAQEBAQEBAQEBAQEBSCWgMFGEDDBAIDMAL74QAAAZAAAADwAAAAAAAAAAAHjmAiMAAAAA/gBDRzAwMgExNDFXRAogAAAA/gAXNkJKbo60/wIBCiAgAB8= + status: connected + enabled: enabled + dpms: On + modes: 1440x900 + edid-base64: AP///////wBMo1dEAAAAAAAQAQOAHhN4Cof1lFdPjCcnUFQAAAABAQEBAQEBAQEBAQEBAQEBSCWgMFGEDDBAIDMAL74QAAAZAAAADwAAAAAAAAAAAHjmAiMAAAAA/gBDRzAwMgExNDFXRAogAAAA/gAXNkJKbo60/wIBCiAgAB8= DRM.card0.VGA.1: - status: disconnected - enabled: disabled - dpms: Off - modes: - edid-base64: + status: disconnected + enabled: disabled + dpms: Off + modes: + edid-base64: Date: Sat Jan 15 03:37:57 2011 DistUpgraded: Fresh install DistroCodename: natty DistroVariant: ubuntu DkmsStatus: - vboxhost, 4.0.0, 2.6.37-12-generic, i686: installed - vboxhost, 4.0.0, 2.6.37-11-generic, i686: installed + vboxhost, 4.0.0, 2.6.37-12-generic, i686: installed + vboxhost, 4.0.0, 2.6.37-11-generic, i686: installed GraphicsCard: - Subsystem: Dell Device [1028:01d8] - Subsystem: Dell Device [1028:01d8] + Subsystem: Dell Device [1028:01d8] + Subsystem: Dell Device [1028:01d8] InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Alpha i386 (20101229) MachineType: Dell Inc.
