In case the device has only touchscreen input device and no keyboard or mouse, the top level surface is never activated. The behavior differs from a device which has a keyboard (or gpio-keys, or even uinput-emulated keyboard), where callchain activate()->weston_view_activate()->weston_seat_set_keyboard_focus()-> weston_keyboard_set_focus()->wl_signal_emit(&keyboard->focus_signal, keyboard)-> handle_keyboard_focus()->weston_desktop_surface_set_activated(..., true); sets the top level surface as activated. On device with touchscreen, the above is never called, hence the top level surface is never activated. Add explicit weston_desktop_surface_set_activated(shsurf->desktop_surface, true); into activate() to always active the top level surface. This fixes at least two known issues on such devices: - Wayland terminal cursor is an empty bar (full bar with keyboard present) - Chromium dropdown menus are randomly placed (they are placed correctly when keyboard is present, because then chromium can find the activated top level surface) (From OE-Core rev: 0a2da895284f1687cf75297fb0f4b20cc9b53489) Signed-off-by: Marek Vasut <marex@denx.de> Cc: Steve Sakoman <steve@sakoman.com> Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
