OK, I don't know much about this kind of stuff, but I don't think
there's a problem there. I have an integrated GPU (intel), driver
i915, resolution 1920x1080. It boots (via Refind) with the proper
resolution, and that's it. All the VTs show the same resolution and
font. I don't use a login manager. No problems, no change is supposed
to happen. I start an X session from a login shell, in any VT except
tty1, which I like to keep as console.

I may have missed some announcement from you, I'm using

to download it? I would try it before trying to apply the patch

Hello, Jorge.

I'm happy to know my patch is still useful.

I must confess that somebody told me by private email that it fails on
systems which change their screen geometry during boot-up.  For example,
a system which first boots into 80x25, then changes to a frame buffer.
I know why this is happening, but I don't have a machine to debug it on,
so the debugging is happening slowly, with the help of my correspondent.

It also doesn't seem to work on machines with kernel parameters such as
vga=791.

That said, I'm hoping that the failure of the patch on 5.14.4 is just a
simple struct change in 5.14, which I hope to have corrected (but in
5.14.5).  What used to be

while (!tty->stopped ...

has now become

while (!tty->flow.stopped ...

I'm assuming that the patch you tried to apply was
5.10.49-scroll.20210715.diff.  If so, please leave it applied (with the
one failed hunk), and additionally apply this:

As always, there are no guarantees.  Please let me know whether or not

Nope. It uses Javascript and dynamic XFA content. None of the
third-party PDF readers support that.

none of evince, atril or pdfstudio support dynamic XFA.

That's an abomination that use Javascript and dynamic XFA content:

Whoever designed something like that for use by the general public
needs to have thier career terminated before they cause any more

On gentoo "app-text/master-pdf-editor-5.7.90" WORKS 
I can read and edit that file.

I can open this file on Windows Acrobat Reader but when I try to  
save/print it as a PDF file via PDFcreator I'm getting some  
Ghoastscript error.
Yes, I see that okular (21.04.3) won't open it.  Actually, okular does  
say "This document has XFA forms, which are currently unsupported.   
It's also odd that the message which is displayed implies that Acrobat  
Reader is available for Linux, even though it's not available.


How is Ghostscript involved on Windows?

Is there any hope of complaining to the Alberta government that there  
is no access to the form without being forced to use proprietary  
software?  (Probably not, but it's a thought.)


Finally, if you search for "acrobat xfa forms linux" you will find some  
suggestions.

Okular 21.04.3 won't work either, I got a message box claiming I need
a newer version of Acrobat Reader and the content of the PDF is a
placeholder that reads “[…] your PDF viewer may not be able to display
this type of document […]”.

A warning above the document says that the document contains XFA forms
that are not supported.

Kind regards, tastytea

You should be able to read them with any PDF reader.  Not all readers will 
allow you to fill in the forms and save with the inserted data.  I use Okular 
for that, but the dependencies may be a lot if you don't already run KDE.  I

I have evince, it will not open it.

This is the form I'm trying to open:

https://cfr.forms.gov.ab.ca/Form/AHC0102.pdf

The javascript code embedded inside explicitely checks for acrobat 
reader version 9.0 or newer, as well as "XFA" (whatever that is) version 
2.0 or newer. Maybe try installing app-emulation/wine and then running 
acrobat reader using wine?

Jack: okular (and poppler apps in general) won't open some (all?) files
with filled in forms.
I had many such files in the past where I had to use acrobat...
