Hi, this series adds support to match on DMI identifiers in InputClass sections. Its main purpose is to be able to workaround the shortcomings of synaptics touch- and clickpads.
In their latest (Haswell) laptop models Lenovo decided to remove the HW buttons below the trackpoint and therefor marks to top area of the clickpad as (soft) buttons, see [1]. But, this clickpad can't be distinguished from any other clickpad being build in other models (i.e. the Lenovo X1 Carbon, which still had the HW buttons) as the product id and revision is the same on _all_ synaptics touch- and clickpads (i.e. in an old T400). It's possible to distinguish between touch- and clipads via device flags. Though, this doesn't gives a hint if it's necessary to configure the top area as a `softarea` in xf86-input-synaptics (as the firmware of the foopad has no clue what the vendor of the laptop painted on it). To be able to distinguish between those clickpads and to apply a special configuration if necessary an additional matching on DMI identifiers is requried. And this series makes it possible to add 'MatchDMI' tokens in InputClass sections for this purpose. One has to add a 'MatchDMI "key|value"' line into the InputClass section to make use of it. 'key' is a DMI identifier and 'value' the desired value. All supported/valid keys are listed in the man-page. An example would be (values out of the had don't have the laptop at hand atm.): MatchDMI "SystemVendor|LENOVO" MatchDMI "ProductName|ThinkPad T440s" This series implements MatchDMI support for Linux only, requiring a decent old kernel providing the DMI informations via sysfs at /sys/devices/virtual/dmi/id. Though, the generic stubs are there and for any other OS it's sufficient to implement the initialization. Sure, this matching is not necessary for installations where someone can modify the configuration as wanted. It's more usefull for distributions and live systems willing to provide some "works out of the box" experience. I hope you'll find it as usefull as I do, Daniel Martin [1] http://www.lenovo.com/images/gallery/1060x596/lenovo-laptop-thinkpad-t440s-overhead-keyboard-2.jpg _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
