Finally, and thanks to Xubuntu guys, the notifications in the Lubuntu desktop will look properly. This is an old bug (see #1362555), affecting multiple themes, crossing and assigning incorrect values to some GTK widgets. But now they’re fixed. If you want to fix it in your system, you must add the Lubuntu Artwork PPA to your system (instructions here). This is how it looks now:
Lubuntu 15.10 will be released in october with the codename Wily Werewolf, as Mark Shuttleworth announced today. A lot of changes will come with version, unfortunately, until the preliminary meeting, I can’t explain the details. Anyway, you all know where are we heading to, don’t you? 😉
The nice icon is an artwork from HopStarter.
