Yes exactly that I was afraid , each time you close the slicer then you have to re write the name and password !! that why mozilla is best for such reminding.. and hope you find solution that not forced user to log in prusa acc !! for my all customer it's not good ..

That is not my issue. I cannot enter the login password into the slicer at all, as the dialog box pops up blank and never fills in. The same happens with the Physical Printer tab. My guess is the Webkit integration is not working correctly. There are no error messages related to the popup or page selection, but lots of error messages when started on the command line.

oulla are you sure is not missing 1 files !!!!!!!!!!!! haha so much.....

[ThomasBoettcherHolschen]

Just installed the Slicer Version 2.8.0 via Flatpack on Linux Mint 21.3.
This is what happens when I click Login:

I can see changes in the Cursor when hovering the Form. I can click on something, but I don't know what happens ;-)
Let me know when you need more info.

[snhirsch]

I'm having the same issue: Version 2.8.0+linux-x64-GTK3 running on Kubuntu (KDE desktop) 18.04. Everything in the slicer works fine, but it doesn't show anything but a blank screen under 'Prusa Connect'. I should add that the Prusa Link interface is working fine (after figuring out that I needed to specify login information).

[grndkntrl]

Same problem on v2.8.0 on Win 11 x64:

I just updated from v2.6.4 which was fine,

Completely uninstalling & reinstalling from scratch doesn't fix it.

[Rose-David]

Same issue on NixOS 24.11 Vicuna. I attached a log snippet of what happens when I attempt to open the login window.

failed to bind extensions

[Rose-David]

I can see changes in the Cursor when hovering the Form.

I tried to see if I could interact with anything, by selecting all and dragging, and I got this:

It says "Connection failed, Something went wrong."

There doesn't appear to be anything else hidden as far as I can tell.

[Rose-David]

So, @30350n found out that these invisible messages briefly tell you to install glib-networking, and once we rebuilt the package with that in the buildInputs, it worked flawlessly!

Can someone on another OS try this to see if it works?

[snhirsch]

I'd love a fix for my Linux installation and would be interested in building here. However, I'm not an expert on cmake and you have not provided quite enough detail for me to proceed.

[30350n]

(In theory you shouldn't have to mess with cmake at all, but just install glib-networking. I'm guessing it's automatically detecting whether or not it's present.)

[snhirsch]

I do have it installed. I'm still running Ubuntu 18.04 LTS since upgrades break too many things. I extracted the contents of the release Appimage and checked all compiled objects with 'ldd'. The slicer itself is dynamically linked to libglib.so.blah, but that's the extent of obvious glib references.

I guess I don't understand the "..once we rebuilt the package with that in the buildInputs.." statement above.

[30350n]

Ah, if you are using the AppImage then this is probably not going to be helpful. The buildInputs thing it NixOS specific, basically a way to declare build dependencies (NixOS is building PrusaSlicer from source).

[snhirsch]

I cannot build from source on Ubuntu 18.04 LTS. The available Boost library is one minor version too old, apparently. One of these days I'll upgrade my system... For now it's the end of the line.
