Pozastavení Xfce během hraní her

[Michal Štrba]

Window manager (Xfce 4.8 ) je pocas hrania fullscreen hry vlastne zbytocny. Je mozne ho po dobu hrania takej hry pozastavit? Navadilo by mi ani kedy som musel nieco taketo: prikaz_pre_pozastavenie; hra; prikaz_pre_spustenie zadavat do terminalu. Dakujem za odpovede!

Tak som to vyriesil tymto skriptom:

#!/usr/bin/env python3

"""pause_xfce.py:

      xfce4-session
      xfce4-panel
      xfdesktop
      xfwm4
   Pozastavi ich pri zadanom parametri "-p" alebo "--pause".
   Spusti pri parametri "-c" alebo "--cont" alebo "--continue"
   Pomoc sa zobrazi pri parametri "-h" alebo "--help"
"""
