Comment 3 for bug 921941

Hi Clint,

The mtrack driver is not well maintained (and not maintained at freedesktop.org like the other drivers) so it is not something we want to include in -input-all. For this hardware we recommend using the -synaptics driver, which is better maintained.

That said, despite the maintenance problems mtrack does have a few features that -synaptics lacks currently, so we're ok leaving it in the repositories for users to optionally install at their discretion. However, since -mtrack is maintained separately from the rest of the X stack, when we update the X stack it will need to be updated as well, and may fail to build until then, so if it's mentioned in your xorg.conf your system may fail to boot properly; this is probably the root cause of the issue you encountered. Robert mentioned the driver is building now so perhaps the problem has resolved itself.

Ultimately, whatever features -mtrack provides need to be incorporated into either the -evdev or -synaptics driver.
