As admin i want to block the clipboard access in Linux GUI. No user can copy data from terminal or other thing. In simple terms it means just block the copy option.

I don't expect you'd be be able to easily disable the X selection mechanism, but you could start a process that connects to every X server that steals the selections (and empty the CUT_BUFFER0) every time a process tries to own them. Here using xclip and xprop utilities, though you'd probably want to write a program that does the equivalent to make it more lightweight (especially if using a clipboard manager that would try and constantly steal back the CLIPBOARD selection off you).

Like:

for sel in clipboard primary secondary; do
  while xclip -i -sel "$sel" -q; do
    xprop -root -format CUT_BUFFER0 8s -set CUT_BUFFER0 ''
  done &
done <> /dev/null >&0 2>&0
  • for steals the selection for Admin it's not a big deal . there are lots of tools available to check it out. – Sanjay Nigam Oct 12 '16 at 10:13
