Aw: Re: LabPlot - Cannot print or export

Tue Jan 5 01:33:58 GMT 2021

Hi Alexander -

I brought up a test machine under KVM to see if the flatpak would work.  It sort of works, though as far as I can tell it will not save any file.  It certainly does not save files to the directory I tell it to.  I tried saving a project and printing a PDF with the target being /home/bgee/Documents ...  but nothing ever appears there.  Curiously, when I reprint to the same filename, it says that file already exists!  Double curious - Exporting as a PNG does put the file where I expect it.

There is something weird going on.  Are the files being saved inside a virtual environment?  If so, how do I get to them from outside the virtual environment?

Flatpaks, snaps and containers all strike me as a very neat solution for which no problem exists.  It took about 1 gigabyte of downloads to support a program that is less than 20 megabytes in size.  It won't save files where I tell it to.  The filename dialog boxes always pop up behind all other windows when they should be at the top of the Z-order.  If I change themes, colors, icons, pointers, the changes are not used by the flatpak application.

So what is the advantage?

To workaround this problem now without upgrading to the most recent version (should be the preferred way, though) is to create a "stand-alone" spreadsheet. So, just create a new spreadsheet without the workbook and import your data.

There is no error, no windows pop up, nothing is printed ...  How can I get these features to work?  It is almost like LabPlot thinks there is nothing to print.

Flatpaks are not an option because the flatpak package requires Wayland, and I cannot run that.  The nVidia display driver does not work with Wayland.  And as a matter of sensibility, the flatpak wants to install something like 2 gigabytes of stuff.  WTF?????
