I have two Intel NUC’s (1x BXNUC10i3FNK2 and 1x BOXNUC8i3BEK2), both with Lubuntu 20.10
Both have the issue they blank/sleep the screen after 10 minutes.
Disabled all power settings in Lxde preferences and in the screen saver I disabled screen blanking.
I even disabled the screensaver from auto-start.
Lubuntu 20.10 doesn’t use LXDE, so changes made in LXDE won’t have any impact on a Lubuntu LXQt desktop.
LXDE hasn’t been used for our last five releases of Lubuntu, no LXDE programs are installed by default as they make no sense on a modern LXQt/Qt5 system
@guiverc Thank you for the quick response, you are right, it’s LXQt not LXDE…
I already set the “blank after” to 0 and in settings → advanced disabled the “Fade to black when blanking”.
I already disabled XScreensaver from autostart under Preferences → LXQt Settings → Session Settings → Autostart
I disabled “Power Management” in LXQt Settings → Session Settings → Basic settings
Ok, think I “fixed” it.
I re-enabled the autostart of XScreensaver again and after that the screen did not blank anymore.
(Could be an update as well, but looks like all is fixed now).
