XnView Software

I have finally determined what exactly is going on and why there is such a performance issue.

This problem does not affect all users, but most likely to users of Linux GTK-based desktops, such as Xfce, Cinnamon or MATE, where users try to unify the appearance of Qt and GTK applications.

The ...

XnView: MP 1.9.3 64-bit (Linux) - Libformat 7.226
(Installed with the .deb package)
OS: Ubuntu Linux 22.04.5 LTS (64bit)
Kernel 6.8.0-65-generic
Desktop: Xfce v4.16

1. Description of the Problem

On my system (Ubuntu 22.04, Xfce desktop), XnViewMP v1.9.x is extremely slow when entering ...

Hi Pierre,

I have performed a set of extensive and carefully thought experiments. The detailed report is too big to post it here, so if you agree, I'll send it to you via PM. There you'll find what exactly I did and why my conclusions. I think it is better to put here just a summary of the main ...

@user0, Thanks for the link
@Pierre, I will try with the AppImage of older versions vs the AppImage of latest version. I don't know whether there's a difference in performance between an AppImage vs installation via .deb file, but if there would be (probably not), it would affect all versions in the ...

@Pierre,
I think I know exactly what the OP is experiencing, since I have the exact complaint, though I haven't written a bug report yet: Ever since precisely those days of 1.8.3 or so, in one of the changes -- I think probably to the 1.9.x or perhaps one of the previuos one, I can't tell now -- I ...

I would like to share something that helped me, just as suggestions topics, that I gathered with the help of IA, (Google's Gemini and GPT-4), because it's not easy to find enough documentation on how to correctly use the Linux feature of logging `stdout` and `stderr` to certain files. This is just ...

Note that this problem has been already mentioned in 2019 this thread: https://newsgroup.xnview.com/viewtopic.php?p=154315&hilit=xsession+errors#p154315 and also I happen to have mentioned by the end of that year in the middle of some post regarding another issue, which was more serious, but had ...

XnView: MP 1.9.3 64-bit (Linux) - Libformat 7.226
(Installed with the .deb package)
OS: Ubuntu Linux 22.04.5 LTS (64bit)
Note: Affects all previous versions of XnView

Description:

XnView writes an excessive amount of irrelevant data to the `stdout` and thus automatically to the `$HOME/.xsession ...

It should be separate feature, eg "Clear tools history"

Sure, as long as it is somewhere in a logic place.

I doubt this is worth implementing, as the scope of this functionality is too uncertain

This assertion is not correct or fair.
First, if you refer to the rather exotic examples, then you ...

Thank you so much for having a look at this.

?? There is no [History] section

Sorry, my mistake, this was a copy/paste error from my notes. The intended section was: [Convert] .
In order to help new readers of this thread, I will fix the original post, explaining the mistake.

Why?

About the ...

Settings - Interface - "Purge now" removes the contents of the ' History= ' field in the [Start] section in xnview.ini , (with some limitations per bug https://forum.xnview.com/viewtopic.php?f=95&t=47042&sid=d023730ca6ca4b6cc129ef9aa1b28fc2 ), but it does not remove several important file history ...

The problem also affects the version 0.94.1.

On a long session of troubleshooting and investigation, I captured debugging information that I think is quite relevant. Odd enough, the place where I found this XnView debug information, is in the ~/.xsession-errors file.

In fact, this is creating a ...

Thank you, Pierre.
Ok, I will do as mentioned. Please allow me a little of time, I want to make those experiments to see if I can provide you something more for you to work with. I know it's difficult with not so much information that what I have currently. I am not sure if I can dedicate time today ...

do you use 'actions'?
Yes. I had been using one: "Level". Sometimes I was using a "scritp" of three actions: a resize, autolevels and sharpen, that I had saved as a script (see below).

is it possible to have these 74 jpeg files?
That particular set I would prefer not, but if you give me a ...
