From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Accidentally uninstalled an important package in Debian Sid with KDE, transparency no longer working (lemmy.world)

Hi everyone, I ran apt full-upgrade last month and accidentally deleted a couple packages that weren't supposed to be removed, due to me not paying enough attention. I could recover most of the system just fine, since most of the missing features and related packages were obvious to me. However, I still couldn't figure out why transparency is not working on KDE, both in Wayland and X. I suspected it could be a missing compositor, but libwayland and libqt6waylandcompositor6 (and related packages) are all installed (and that wouldn't explain why it isn't also working on X).

I have attached a screenshot to illustrate what I mean.

I would appreciate if anyone could help me figure out what package might be missing that is causing this issue. Thanks in advance!

EDIT: Thank you so much everyone! I finally solved my problem. I just had to replace libqt5quick5-gles by libqt5quick5 (non gles version).

Commandline: apt install libqt5quick5
Install: libqt5quick5:amd64 (5.15.10+dfsg-2+b2)
Remove: libqt5quick5-gles:amd64 (5.15.10+dfsg-2+b2)

Just reinstall plasma-desktop or however the metapackage is called

[–] KillingTimeItself@lemmy.dbzer0.com 11 points 7 months ago (1 children)

dont install the meta package unless you used it on install. It can cause shenanigans if you aren't careful, especially with application meta packages.

Or do, im not your mom lol.

Yeah, I tried installing kde-full but it didn't solve my problem.

There is tasksel in debian to install DEs ig. Maybe try witj that, and also try reinstall instead of install

[–] buffy@lemmy.world 2 points 7 months ago (1 children)

Tasksel seems to be correctly set,

~$ tasksel --list-tasks
i desktop       Debian desktop environment
u gnome-desktop GNOME
u xfce-desktop  Xfce
u gnome-flashback-desktop       GNOME Flashback
i kde-desktop   KDE Plasma
u cinnamon-desktop      Cinnamon
u mate-desktop  MATE
u lxde-desktop  LXDE
u lxqt-desktop  LXQt
u web-server    web server
u ssh-server    SSH server
i laptop        laptop

I tried apt reinstall kde-full, but unfortunately nothing changed.

Maybe a bug idk

[–] buffy@lemmy.world 3 points 7 months ago

Indeed it looks like a bug. I finally found a solution, though. Check the main post edit for details.
