I would like the following functionality:
bindsym --release Print exec --no-startup-id scrot -z
bindsym --release Mod1+Print exec --no-startup-id scrot -zu
bindsym --release Shift+Print exec --no-startup-id scrot -zs
Lines 1 and 3 work as expected.
Line 2 does nothing.
I have tried using bindcodes instead. I have also double-checked checked xev and xmodmap outputs.
Am I doing something wrong?
There are two likely causes for this issue:
i3 internal: Since version 4.11 (at least in some cases) the key symbols used with bindsym need to be the ones that X recognizes when the given Modifiers are pressed. In your case with Alt+Print that means you have to actually use
bindsym Mod1+Sys_Req exec --no-startup-id scrot -zu
Because the key symbol of the Print key is actually Sys_Req when when Alt is pressed.
Kernel configuration: It is also possible that the MAGIC_SYSRQ configuration option is enabled in your Linux kernel. Depending on your distribution and kernel configuration, you may be able to check this with one of these lines:
grep CONFIG_MAGIC_SYSRQ /boot/config*
zgrep CONFIG_MAGIC_SYSRQ /proc/config.gz
With this option enableMod1+Print is caught by the kernel as part of the Magic System Request Keys, which all follow the pattern Alt+Print+[b-z0-9].
As it is caught by the kernel itself, the only thing you could do, would be to use a kernel that has this option disabled or disable it temporarily (until next boot) with sysctl -w kernel.sysrq=0. (Credits for the sysctl-workaround go to beanaroo)
Strange, on my machine `xev` reports Print as Sys_Req when Alt is pressed, which actually reminded me of the recent change. Checking the source repository of xev does not reveal any (obvious) changes that would explain this. But as long as it works now, I am glad I was able to help.
