Download beaglebone rootfs and install it to MMC 2. Boot up the system The matchbox can startup without problem, but there is no mouse. When I use keyboard to launch an application (e.g. Terminal), the mouse is back and run without problems. 63522 1 ross.burton 2016-06-30 14:47:01 +0000 My spider-sense says this is something to do with formfactor. 63861 2 edwin.plauchu.camacho 2016-07-12 18:56:19 +0000 Mouse is working well! # hexdump -v -e '3/1 "%02x " "\n"' /dev/input/mice 18 ff 00 18 fe 00 18 ff 00 18 ff 00 18 ff 00 18 ff 00 18 ff 00 18 ff 00 18 ff 00 08 01 00 It is mostly a problem related to mouse visualization that disappears when use keyboard to launch an application. It is even possible launching an application with mouse when it is still invisible. 63922 3 leonardo.sandoval.gonzalez 2016-07-13 14:47:56 +0000 Just a comment: For this kind of situations, you may do a git bisect in case you know a good commit (you know the bad one). At the end, bisect takes 'just' log2(n) steps. The problem is that is too time consuming building a whole image each time. 63953 4 edwin.plauchu.camacho 2016-07-13 22:59:26 +0000 When an application is launched, it'll be called "launcher_start" within: matchbox-desktop-2/tree/libtaku/launcher-util.c This call will end up over a method xcb_flush "https://xcb.freedesktop.org/manual/group__XCB__Core__API.html#ga9361ead09eb756ba9cc8953c4569a789". So mouse is back and run without problems.
