Je l'ai testé rapidement, et tout est vraiment fluide. J'ai hâte de voir ce que les autres pensent des nouvelles applications !

Wow, that was fast!  Thanks Jerry!

Could you supply the file name and line # with the code change and I'll test again (in dark mode etc.)

Cheers!

I replaced the code in the /bin/lite-welcome file with the code provided and then the app wouldn't open at all.  I noticed that the new code is around 300 lines longer (aprox 1600 lines) than the old code (aprox. 1300 lines).  Was the new code supposed to be that different than the previous?

Thanks

Yes, different code. Make sure the application file is executable.

Should the included version of GIMP be updated to 3.x series?

The current version of GIMP that is included with LL is 2.10.36.  The 3.x version has been available for quite awhile now and 3.06 is the default on the gimp.org website.  When you open in LL and go to "Help > About" it recommends updating.

The Flatpack works OK. There is no native complete package for Ubuntu 24. Even the PPA has limitations.

I added the ubuntuhandbook1/gimp-3 PPA and it upgraded fine that way afterwards but it doesn't sound like it's as up-to-date as the flatpak or snap versions so maybe not the best way to go but it's nice that it will updates with the rest of the system via "apt update" etc.

Option 3: Ubuntu PPA (unofficial)
For those who prefer the native

Code:

.deb

package format, I’ve built GIMP 3.0 into this unofficial PPA for Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 24.10 on

Code:

amd64

,

Code:

arm64

/

Code:

armhf

platforms.
NOTE: The PPA package has few downsides:

1. It’s built with system GTK3 library, which is a bit outdated. While, GIMP 3.0 relies on the most recent GTK3 library for some fixes.
   
2. Also due to outdated library (libglib2.0-dev), the Ubuntu 22.04 package reversed this commit, or it won’t build.
   
3. For Ubuntu 22.04, the PPA also contains updated versions of libheif, libwebp, kvazaar HEVC encoder that might conflict to other 3rd party packages.
   

To add the PPA, press

Code:

Ctrl+Alt+T

to open up a terminal window, and run command:
sudo add-apt-repository ppa:ubuntuhandbook1/gimp-3
