===How do I identify the type and model of the keyboard and touchpad on my XO?=== |
||
In [[Terminal activity]], type this: |
|||
See [[Touchpad/Testing#Identification|how to identify the touchpad on an XO]]. |
|||
cat /sys/bus/serio/drivers/psmouse/serio*/protocol |
|||
The value displayed is the protocol of the communication link between the computer and the touchpad. Possible values include: |
|||
* PS/2 - using the base PS/2 protocol for compatibility |
|||
* SynPS/2 - Synaptics touchpad, in Synaptics protocol mode, on old kernel. |
|||
* SynRelPS/2 - Synaptics touchpad, in relative protocol mode, on latest kernel (XO-1, XO-1.5, ...) |
|||
* FSPPS/2 - Sentelic AVC Finger Sensing Pad (XO-1.75, XO-4). |
|||
Alternatively, look at the boot messages, type this: |
|||
dmesg | grep psmouse |
|||
Example output, XO-4: |
|||
[ 11.001718] psmouse serio1: sentelic: Finger Sensing Pad, hw: 13.2.6, sn: 0, sw: 1.1.0-K |
|||
Example output, XO-1.75 with Sentelic touchpad: |
|||
[ 8.937258] psmouse serio1: ID: 10 02 64 |
|||
Example output, 13.2.0 on XO-1.5 with Synaptics short touchpad: |
|||
[ 15.804359] psmouse serio1: synaptics: OLPC XO detected, not enabling Synaptics protocol. |
|||
[ 19.228099] psmouse serio1: synaptics: Touchpad model: 1, fw: 6.2, id: 0x92a0b1, caps: 0xa04711/0x200000/0x0 |
|||
Example output, 13.2.0 on XO-1 with Synaptics short touchpad: |
|||
[ 16.447317] psmouse serio1: synaptics: OLPC XO detected, not enabling Synaptics protocol. |
|||
[ 18.583646] psmouse serio1: synaptics: Touchpad model: 1, fw: 6.2, id: 0x92a0b1, caps: 0xa04711/0x200000/0x0 |
|||
Possible values include: |
|||
* XO-1; 50 |
|||
* XO-1.5 older CL1A; synaptics |
|||
* XO-1.5 newer CL1A; serio1: ID: 10 02 64 |
|||
* XO-4; Sentelic, as in the example above. |

Mouse, Touchpad
Can I attach an external keyboard or mouse?
Most USB keyboards and mice are compatible with the XO.
IR (infrared) keyboards (e.g., "PalmPilot keyboards") and wireless (Bluetooth) keyboards are not supported on the XO-1, XO-1.5 or XO-1.75 laptop.
Bluetooth keyboards and mice can be made to work on an XO-4 laptop if the laptop was built with the dual purpose wireless card.
Is there a stylus for the touchpad?
The first XO-1 touchpad was designed to be able to work with a stylus, but the laptop does not ship with a stylus.
Currently there are no activities that use the stylus.
Why is my touchpad jumpy?
At times, the touchpad will become jumpy and the system will recalibrate it. If this happens, keep your fingers away from the touchpad for five seconds. You can also force a manual recalibration.
There were three known touchpad issues. We recommend upgrading to the latest software. A USB mouse is also a useful workaround in extreme cases.
Why did my mouse and keyboard freeze in 2011?
Users running XO-1 builds 650, 653 and 656 from 2007 and very early 2008 are encountering touchpad/keyboard freezes when their system clock is set to 2011 and 2012. A quick solution to the problem is described on the wiki and summarized in this blog post.
Users should also strongly consider a longer-term solution -- upgrading to the latest official software release -- remembering to remove all power (battery AND power cord) after upgrading/reflashing.
