pngquant -f --ext .png --quality 70-95 MyPicture.png

Thanks, this is great. I have been avoiding adding many png (wallpaper) images due to the large size.

Your welcome.
you can do this recusively for all .png by:

Code: Select all

cd /the-baseDir
find . -name '*.png' -exec pngquant -f --ext .png --quality 70-95 {} \;

PS: Maybe you can also provide a custom config for eepc (with small screen like: 1024x600 )

Yes, for sure. This annoyance of odd-looking wallpaper of large resolution on a small screen can now be solved. There will be a similar script that adjusts panels and buttons as per screen resolution.

Thanks Rasat, I didn't know.

Installed pngquant and experimented with the compression ratios. I wish there was a GUI version to preview the results of the different compression ratios but it all worked eitherway!

Hello,
I have tested a little bit more (the memory side) , and fvmw3 is in the middle range (beetween IceWM and XFCE4 DE), FvwmButtons consumes some extra memory.

Can you identify which FvwmButtons?

... Yes I guess from:
/home/user/.fvwm/extraEXT/MODULES/DashToDock/dashToD.sys

So, you compared the memory usage with the extensions? Do the test with the default Fvwm3.... empty .fvwm folder.

Yes, without this extension (dock like or buttons), fvwm has the ~ same footprint as Icewm, or Fluxbox (without dock too by default), or I3.
It is nice, it was just to advise (with only tint2 the footprint is better).

This means optimizing the extensions for lower memory usage.

About the wallpaper of different screen resolutions. At last, after breaking my head in creating a script, I found the solution.... tiled wallpaper. The default Fvwm wallpapers (480x480) are tiled.

With Gimp you can create your own seamless images.
https://www.linuxtopia.org/online_books ... ode83.html

Click menu bar: Filters → Map → Tile Seamless

I did a test on .fvwm/images/background/myExt-1920x1080.png
https://rasatpc.net/screenshot/myExt/Ti ... 00x675.png

Tiled image (seamless) 900x506 that will work well on a screen 3840x2160 and 1024x600.

Another method of creating a wallpaper is with xsetroot by using different numbers. For example, run this in terminal:
