screen parameters per user

screen parameters per user

[Charles Hallenbeck]

Hi all,

I have never seen any references to this, but on the chance that someone 
has run across it, I would like to ask this:

Is there a way to have different screen parameters (columns and lines) 
on a per user basis in Linux? I have become very attached to my enlarged 
screen, 132 by 60, but would like to allow access to a user account via 
ssh for someone who will not be comfortable with those dimensions. Is 
there any way to revert to an 80 by 25 screen just for that user, or for 
that session, without reverting to those figures for the whole system?

Any ideas or opinions appreciated. Ideas preferred of course, but 
opinions welcome too.

Chuck

Hi.

The screen parameters won't be the same for a ssh session as a console
one.  The screen parameters are only in effect for the physical
hardware.  For example, all my ssh sessions use the default screen size
of my work station no matter what computer I log into.
If you are using a frame buffer to get the large screen size, and your
frame buffer driver supports it, you can have different screen sizes on
different virtual consoles.  

Hope this helps.

Hi Kenny,

Yes, that encourages me to experiment. Thanks.

When some one logs into your system from a remote system, the screen
parameters will be defined by settings on their remote system--not by
the settings you have set up for the console(s) on your system.
Setting up your system to work with certain parameters to allow for a
specific number of rows and columns on the console screen sets those
parameters to work with the video card/controller installed in your
system.  Remote systems which are used to log into your system are
likely to have different video cards/controllers, so the remote system
sets the operating parameters for displaying text or whatever.
Chances are that you will not have to make any adjustments on your
system--just have the person log in from the remote system via ssh (as
you described), and everything should work fine.

HTH, and have a _great_ day!

Thanks, Ralph. I guess I am anticipating problems that don't exist. 
Kenny's earlier comments made that clear too. When I connect to other 
systems, my own console continues to have the dimensions of my own 
machine rather than the foreign host.

I have been thinking it would be neat to have the same type of thing 
available in Speakup--instead of system-wide speech parameters, we 
could have user-specific.  I guess this could be accomplished if we 
made /proc/speakup accessible to all users then putting a script in 
each user's home directory.

I stand to be corrected, but /proc is accessible to all users, at least
that's true on all the systems I've worked on so far.

Re: screen parameters per user

[Charles Hallenbeck]

Are you familiar with the speakupconf script? It can be asked to load a 
set of user specific and synthesizer specific parameters upon a user 
login. But what I was after was not speakup parameters, but the 
underlying screen size, the number of columns and lines on the screen. I 
am assuming speakup would read the whole screen, whatever its size. 

>From other posts though, accessing my system with ssh solves my original 
problem. i.e., how to avoid asking a remote user to use a magnifying 
glass to read my teeny tiny print <smile>. It turns out that it is the 
remote user's screen parameters, and not mine, that determine what he 
sees.

Re: screen parameters per user

LOL I'm sorry; it probably is.  I didn't stop to think about that.  I 
have just never tried it and went by the idea that anything outside 
of the user's account directory isn't writable to that user.
