Desktop Theme writer/modifier ?

[GregM]

Is there a program/editor that will allow me to modify an existing desktop theme and just change a couple little minor things?
Like instead of having a transparent task bar have it be solid?
Otherwise the theme I have is fine.

Just a couple tweaks, that's all.

[vinnywright]

their is the "plasma theme explorer" ,,,it should be installed in the "development" section of your menu ,,,,or I have it because of something else I may have installed at some time .

I cant help with how to use it however

[vinnywright]

OK it's part of the "plasma-sdk" package .

Some "themes" just won't be removed.
Try as I might I can't get rid of "Breeze".
Is there some terminal code to do this? or will I really screw things up by trying?

[Snowhog]

Is Breeze the only Desktop Theme installed? If 'yes', I'm not surprised that you can't remove it.

[GregM]

No I have several...Air...Oxygen...and a few Breezes with variations.
I just can't remove any of the Breezes

[GregM]

Reading around on the net a mention was made of

/usr/share/sddm/themes/
and breeze is the only one listed.
Maybe that's why?

Seems like when you add themes via the System Settings it should appear there?

[vinnywright]

themes installed by the user in this way go to "~/.local/share/plasma/desktoptheme

doing a simulation seems to just remove the the packages neon-desktop plasma-desktop and breeze and NOT all the packages that they depend on (your hole desktop) ,,,,,,,,,,,,,,,,,,,,,,,,,,

vinny@vinny-Bonobo-Extreme:~$ sudo apt-get -s remove breeze

Remv breeze [4:5.12.2+p16.04+git20180226.1623-0]

BUT you do it at your own risk .

I dont think I would , you can just use the themes you installed and forget Breeze is their .

O and /usr/share/sddm/themes/ is just the theme for "sddm" , their are others you can install for sddm

Thanks for the valuable message

[chimak111]

On my Kubuntu 16.04 with kubuntu-backports, I get something more ...

$ apt purge -s breeze
NOTE: This is only a simulation!
    apt-get needs root privileges for real execution.
    Keep also in mind that locking is deactivated,
    so don't depend on the relevance to the real current situation!

And apt-show plasma-desktop doesn't indicate that it's a metapackage.

I'd echo the advice to keep the system themes even if you have others.

Finally!
I was able to install and fix the problem with "Classic Theme Restorer".
I finally pushed the right button and the blackness left.
What a job...

[chimak111]

Isn't Classic Theme Restorer a Firefox extension available in Firefox versions older than Firefox 57?

[GregM]

Correct
It took away not only the blackness from FF but also from Thunderbird and a bunch of other apps.
Can't explain why it works, but it did.
The blackness is gone

I find the "a bunch of other apps" bit very difficult to understand.
