Hm, we may be talking about two different things here? I have been doing a minimum system bring-up for 3.16, with openSUSE userspace. My YaST-selected system keymap (German with deadkeys) is not taking effect on German Spring at the *framebuffer console* (tty1) - evdev is not involved at that level AIUI. Backspace and L-shaped enter keys work okay. The keymap here should be identical to that in the original German device and seemed to match that in the exynos5250-snow.dts file. I just checked (w/ dp-controller, hdmi, fimd commented out in my patch): * An external USB keyboard does not work correctly either. * In X11 (xdm), both internal and USB keyboard work as expected. Similar situation in ChromeOS IIRC, with keymap correct at graphical login but not on the right-arrow console - although I don't know the ChromeOS userland too well to judge if it was configured correctly. > If you are having other problems with keyboard layout being stuck to > US QWERTY, please check your user space. On my Raspberry Pi for instance, the equivalent openSUSE Factory works just fine with German keymap for USB keyboard. Might any related kernel config options be missing in exynos_defconfig? Anything in particular I should check in user space?
