Workaround (1): press and hold Print Screen press and hold Alt release Print Screen (and then Alt)
This seemed to work for me, but it shouldn’t be necessary. Workaround (2) For Laptops if Printscreen is combined with Sysreq: sudo sysctl -w kernel.sysrq=1 #disables magic sysreq for that session. Press Alt+Printscreen or Alt+Fn+Printscreen (first Alt, then Fn). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1732612 Title: Alt+Printscreen not working (doesn't generate keypress event) Status in systemd package in Ubuntu: Confirmed Status in unity package in Ubuntu: Confirmed Bug description: Since I have upgraded to Ubuntu 17.10 Alt+PrintScreen doesn't work on my computer.
