I installed Lubuntu 20.04 LTS and I did the upgrade of system (sudo apt upgrade
).
But this function don’t work. I installed Evince and I setting as default PDF reader, but don’t work.
As you see in image above, the pdf thumbnail don’t show. I installed Nautilus and the thumbnails work well, just PCManFM that don’t work.
I tried with official Ubuntu 20.04 LTS on live mode and thumbnails work well. I installed PCManFM-qt on Ubuntu and worked too! See the picture:
Anyone knows some way to enable this feature on Lubuntu??? I am dummy in this subjects. I think is some problem on DBus or something like.
