Lubuntu 18.04, PCManFM 1.2.5, PDF Thumbnail Previews, Evince downgrade

[ailtonbsj]

The last version of evince on Lubuntu 18.04 has stop the thumbnails preview in pcmanfm.

I solved the problem doing a downgrade:

sudo apt-cache show evince
sudo apt install -y libevdocument3-4=3.28.2-1
sudo apt install -y libevview3-3=3.28.2-1
sudo apt install -y evince=3.28.2-1

Anyone knows how update without crash this feature?
I am waiting for 20.04, but I will continue using LXDE because LXQt don’t work with themes like LXDE.

It looks like it was a security update so you should probably reconsider the downgrade. It does affect thumbnailing specifically. Actually, this part of the security issue. You should file a clear bug report against evince (ubuntu-bug evince) so developers can ensure the mitigation doesn’t affect functionality.

LXQt don’t work with themes like LXDE.

Well, it doesn’t use GTK themes, but it does work with themes. Perhaps there’s a misunderstanding? Explain what you’re trying to accomplish and perhaps we can help you.

Thanks for your answer @wxl,

I’m using lubuntu bionic, and I created a showdesktop like windows just changing icon size to 61x256 px.

Here is my showdesktop on LXDE:

I’m testing lubuntu focal daily and try to create the same showdesktop. But the width of plugin don’t resize and a can’t find a option in file conf to change this.

Here is my showdesktop on LXQt:

It’s too large, you know how fix this?

There’s a reason Lubuntu Bionic didn’t have LXQt: it wasn’t really ready for prime time. I would use a newer version of Bionic and I’m sure you’ll have a better experience overall.
