Hi,
I've just downloaded the latest version of LibreOffice to my laptop.
Much to my surprise, when opening an existing spreadsheet, instead of
the usual black/coloured text on a white/clear background, everything
has been reversed!!
First question is ........... Why?
Second question is .......... How can I get back to what I am used
to?
Many thanks,
Andy
Can't answer the "why," Andy, perhaps a different default or option.
However, go to
Tools > Options
and there to
LibreOffice > Appearance.
The first item in the right pane should be theme. You can either change
the theme (auto/light/dark) or check the box for light background.
I have a dark theme in Mageia Linux, but the light background is
checked, giving black on white. Come to think of it, I may try changing
that. :-)
Hope that helps,
Roy
Actually, the why is simple. Users asked for it for years. It has had
some bumps as it has evolved.
@Andy, you did not say what build if you are on a 25.2 release the
Appearance theme manipulation is different than the upcoming 25.8.
=-25.2.5-=
For 25.2 you will want to install and use one of the Extensions 'Light
Application Colors' (specific to the 25.2 release cycle).
Launched from the Tools -> Options -> Appearance panel, the button next
to the list box with 'Auto/Light/Dark' selections.
Select to install the 'Light Application Colors' or another theme marked
>= 25.2, "Lime" or "Ocean Blue" (*not any of the those marked >= 25.8).
Once installed, the appearance themes will be available to select from
the list box. Do not use the radio button/check box for
'System/Light/Dark'
Restart. If still muddled on relaunch. You may need to fully
remove/rename the LO profile and start over with the theme selection.
=-25.8.0-=
If you are on a 25.8 release (25.8.0.2 rc2 should be out this week),
Appearance theme got additional rework, but the defaults give back the
WYSIWYG white background folks wanted.
The handling of the os/DE Automatic/Light/Dark radio buttons is more
reliable, but still better to leave the os/DE in default 'Automatic'
If installing and using an Appearance theme, the extensions to use for
25.8 are labeled >=25.8 (*do not use a >=25.2 theme with a 25.8 or 26.2
build*).
Applying the theme, and switching back to os/DE defaults is more
reliable, and the Tools -> Options -> Appearance panel has additional
checkbox control--just works better.
You still need to 'restart' LibreOffice *when making an Appearance theme
selection or reverting to os/DE defaults* to fully refresh, but that is
being worked on as well.
=-Note-=
Again, Dark/Light os/DE support and ability to theme LibreOffice has
been a long running user request--it is evolving.
Hope that helps, and you can always get a look at what is coming next
using a nightly build installed in parallel to your working
installation.
