Thank you for your help.

gwenview -v

This helps for help you.

Hi! For what it’s worth, it might be a bit tough in this case, as a lot of the software involved is pretty out-of-date at this point compared to the upstream projects. For example, that Gwenview version is over three years old and long-unsupported upstream, so any updates that are happening to it are patches being put together by the Ubuntu or Linux Mint maintainers, rather than KDE developers.

With that caveat - can you try opening a terminal and trying to launch Gwenview from there, and letting folks here know what output is printed to that terminal?

thanks for you reply :

mike@mike-OCTO:~$ gwenview
Icon theme "breeze" not found.

Breeze is the standard theme of Plasma.

I think too that you need to update Plasma (at now is 6.3.5) and Gear (is the package of applications for Plasma by default, Gwenview is one of these, at now is 25.04.1).

which is:

The “kinfo” command has not been found, but there are 19 similar ones.

kinfo is pretty useful to have, so to get it do:

sudo dnf install kde-cli-tools

nickg001 · May 12, 2025, 12:04pm

ok I installed kde-cli-tools so how i can open it?

Krovikan · May 12, 2025, 1:59pm

I guess that this package (I use openSuSE TW) is a pack of commands of kde for the use in console (CLI).
Now, you can type kinfo.

I got it

Krovikan · May 12, 2025, 2:41pm

Plasma (at today) is tested in Wayland session only (from 6.0 version).
Developers touch (I think) X11 only to do some security fix until Plasma drops some day the X11 session (yes, the tip is that everyone needs to switch to Wayland session asap).

But someone maybe can help you to know what’s happening to you.

thanks for your answer

johnandmegh · May 12, 2025, 4:51pm

@Krovikan the OP is (at least originally) using the Cinnamon desktop environment on Linux Mint, not Plasma, which is why kinfo and things like that weren’t working

@nickg001 It might be worth trying to reinstall Gwenview from the Ubuntu repositories, in case some dependency changed over the course of an update? The Flatpak for Gwenview might be a good option as well, if the Ubuntu/Mint repository version is having issues.

Thanks for clarify. I didn’t realize because he/she is asking in KDE forum.
