# 20180704 bkw: wrapper for snapscreenshot, determines the current tty
|
|
# and takes a screenshot of it by calling snapscreenshot with the
|
|
# appropriate arguments.
|
|
|
|
# I tried to make this work under X. You can find out which tty X is using
|
|
# with: xprop -root | grep ^XFree86_VT | cut -d' ' -f3
|
|
# However snapscreenshot itself fails because that console will be in
|
|
# graphics mode (no text to read from /dev/vcs$TTY, so it'd give a
|
|
# blank image).
