is there a way to check programmatically (via ioctl(), etc.) or by reading a file in /sys, /proc or /dev) whether the screen has been blanked by the Linux console screensaver?
Thanks and best regards,
Günter

You can parse the output of xset q
with DISPLAY
set, but it’s not pretty.
$ xset q Keyboard Control: auto repeat: on key click percent: 0 LED mask: 00000000 XKB indicators: 00: Caps Lock: off 01: Num Lock: off 02: Scroll Lock: off 03: Compose: off 04: Kana: off 05: Sleep: off 06: Suspend: off 07: Mute: off 08: Misc: off 09: Mail: off 10: Charging: off 11: Shift Lock: off 12: Group 2: off 13: Mouse Keys: off auto repeat delay: 250 repeat rate: 30 auto repeating keys: 00ffffffdffffbbf fadfffefffedffff 9fffffffffffffff fff7ffffffffffff bell percent: 50 bell pitch: 400 bell duration: 100 Pointer Control: acceleration: 20/10 threshold: 4 Screen Saver: prefer blanking: yes allow exposures: yes timeout: 0 cycle: 600 Colors: default colormap: 0x20 BlackPixel: 0 WhitePixel: 16777215 Font Path: /usr/share/fonts/misc,/usr/share/fonts/100dpi:unscaled,/usr/share/fonts/75dpi:unscaled,/usr/share/fonts/TTF,/usr/share/fonts/Type1,/usr/share/fonts/misc/,/usr/share/fonts/TTF/,/usr/share/fonts/Type1/,/usr/share/fonts/100dpi/,/usr/share/fonts/75dpi/,built-ins DPMS (Energy Star): Standby: 1200 Suspend: 1800 Off: 0 DPMS is Enabled Monitor is On Font cache: Server does not have the FontCache Extension
