With this version, DPMS is not working anymore. The screen always is on
and does not go to sleep anymore.

When I use the settings dialog, the setting is disabled. Enabling it and
restart settings and it is disabled again.

As it is very important for xscreensaver to go to DPMS sleep after some
time (especially on laptops), this is a major problem.

Hi, thanks for your report. Which version did you use before?

It looks like I can reproduce this. I enable settings in the GUI and:

$ grep ^dpms ~/.xscreensaver
dpmsEnabled:    True
dpmsQuickOff:    False
dpmsStandby:    0:01:00
dpmsSuspend:    0:02:00
dpmsOff:    0:03:00

It stays the same after closing the settings. After opening the
settings GUI again, it stays "True" in the file until I switch to the
"Advanced" tab, where I find it disabled again.

$ grep ^dpms ~/.xscreensaver
dpmsEnabled:    False
dpmsQuickOff:    False
dpmsStandby:    0:01:00
dpmsSuspend:    0:02:00
dpmsOff:    0:03:00

It looks like opening the Advanced panel forces the "Power Management
Enabled" to off.

Best regards,
Tormod

With debug logging below. At 14:49:27 I click to select the Advanced
Tab, without changing anything. However the logs says "dpms_enabled_p:
1 => 0".

In any case, as I understand it, DPMS will stay enabled as long as you
don't go looking at the Advanced tab.

This line changes p2->dpms_enabled_p to zero when the Advanced windows
is opened the first time:

CHECKBOX (p2->dpms_enabled_p,  dpms_button);

(line 1324 in driver/demo-Gtk.c, in flush_dialog_changes_and_save)

Maybe this fixes it?

Yes, many thanks, that seems to fix it.
