[yocto] Problem with mouse and keyboard detection in yocto (core-image-sato on emenlow)

[Andreas Enbacka]

Thanks again for your assistance. I checked /usr/lib/xorg/modules/input, and evdev_drv.so is indeed present. 

I will try rebuild the specified modules, and see in case it solves the problem (I have indeed built some atom-pc images previously). 

Thanks,
Andreas

That's interesting, it should be loading the evdev module.  Can you confirm that it's present in /usr/lib/xorg/modules/input?

Your log shows that it didn't load the kbd and mouse modules because the versions don't match:

[3901748.190] (II) LoadModule: "mouse"
[3901748.191] (II) Loading /usr/lib/xorg/modules/input/mouse_drv.so
[3901748.208] (II) Module kbd: vendor="X.Org Foundation"
[3901748.208]   compiled for 1.13.1, module version = 1.6.2
[3901748.203] (EE) module ABI major version (18) doesn't match the server's version (11) [3901748.204] (EE) Failed to load module "mouse" (module requirement mismatch, 0)

This shouldn't happen in master because the server and the modules have runtime-dependences injected to stop this happening:

$ dpkg -I xf86-input-mouse_1.8.1-r21.0.0_armv5te.ipk
...
 Depends: xorg-abi-input-19, libc6 (>= 2.17)

$ dpkg -I xserver-xorg_1.14.0-r8.0.0_armv5te.ipk
...
 Provides: xserver-xorg-extension-extmod, xserver-xorg-extension-dri, xorg-abi-video-14, xorg-abi-input-19, xserver-xorg-extension-dbe, xserver-xorg-extension-record, xserver-xorg-extension-dri2

Something went wrong and your drivers were built with a newer version of the server (1.13.1) than you're actually running (1.9.3). I suspect what's happened is that you've done a non-emenlow build (say, atom-pc) in the same build directory and your emenlow build is re-using the drivers.  Rebuilding the drivers should help, so "bitbake -ccleansstate xorg-input-keyboard xorg-input-mouse" and then re-build your image.
