Created attachment 343 [details] 3.jpg I was trying some BSP board and found this bug. Later I found actually qemu has the same bug, so we can debug this in qemu. Steps to reproduce this bug: 0) press Ctrl+Alt+F to enter fullscreen mode of qemu; BTW, if you're using vncviewer to access your linux host, you might need to press F8 or something to enter fullscreen mode of vncviewer first(or else, Alt+F4 may be interpreted as closing your vncviewer) 1) runqemu qemux86 core-image-sato and we see the sato desktop; 2) run some program(like the terminal): see 3.jpg; 3) press Alt+F4 to close the terminal, so we see the sato desktop again; the difference from that in 1) is: the icon of Terminal is focused; 4)press Alt+F4 again, we see 4.jpg -- matchbox-desktop has exited abnormally and we see a weird window. 5) now let's click the icon of ConnmanD -- the icon near the numerical clock -- we get 5.jpg and let's clock the Close button of the dialog, we see matchbox-panel and matchbox-window-manager will crash -- see 6.jpg. This bug is not that important to qemu since we usually don't use fullscreen mode of qemu. But for BSP, people can be annoyed to meet with this bug as they have to reset the board to get access to the board.

Hello. This can be reproduced in any qemu without full screen by using Alt+C instead of Alt+F4.
I can't replicate this on atom-pc. Either it's machine specific or it's mysteriously fixed itself.
This issue is still present. Steps to reporduce: 1. boot up a core-image-sato-qemux86 image 2. after successful boot, press ALT+C 3. Notice image is in a technical hang Tested in master:7d22ef28e64de06b6238d0ef9b664c0bee6efa46
Could we retest and confirm this is still an issue please?

More reproduction tips: STEPS TO REPRODUCE: 1. After the image boots, open the Terminal from matchbox interface (or other app fwiw) 2. Hit ALT+F4 few times (more then 1 time) to close the Terminal. 3. Open Connman-properties from the top left of the icon 4. Close connman-properties (press the X button on the top right) ACTUAL RESULT 2. The matchbox panel with all the apps will dissapear. Only the "tray" menu from the top left will remain active. 3. Connman appears 4. matchbox crashes. also X server.
