Yes. I also hoped that some device would be modified when switching
to a virtual terminal (so that I could use inotify), but this isn't
the case.

Now, since in practice I switch to a console with the keyboard,
perhaps I could handle the XF86_Switch_VT_* with my window manager
(possible after changing the keysyms with xmodmap if they are in
the way). The script would execute "setupcon --force" just after
chvt.

The above option doesn't have any effect, and I haven't found anything
on Google.

You are right - 1.1 and 1.2 are two symptoms of one problem.

Unfortunately there is no right time for this - there is no script that 
is run after one has switched to a console.  I suppose that if you 
switch to the console, run setupcon, then go again to X and return back 
to the console, the bottom 3 lines will be cut again.  So you will have 
to run "setupcon" again.

The FAQ mentions 

Option "VBERestore" "true"

when one is using the i810 driver.  Maybe there is some similar option 
for the Nvidia driver?

I've done some tests. Running "setupcon" solves the problem
(questions 1.1 and 1.2 of the console-setup FAQ should be merged
to make this clear). Couldn't "setupcon" be run at the right time?
For instance, is there a script that is run after one has switched
to a console?

I'm wondering: what does the X driver have to do with a console
problem? Shouldn't the console code do this by itself?

Also, I'm not sure whether the problem is related, but the
console-setup FAQ says:

   And sometimes the console setup is never remembered.  In this case
   you will have to use framebuffer (try "modprobe vga16fb").  Another
   uption is to to use the "setupcon" utility whenever you need to
   restore the console setup and hope that the problem will be fixed
   in some future version of X Window.  You may want to send a bug
   report to the X developers.
   ^^

But is it dependent on the X driver or not?

nvidia ships an X driver, a kernel driver and a libGL.  While the last
one is probably not the culprit, any of the first two can mess up the
video state.

No, I'm using the non-free driver by Nvidia (the free driver is
unfortunately unusable on this machine).
