[daip] AIPS, multi monitors, and spflg

[Susan Neff]

Hi Eric,

I am having problems with the AIPS TV and spflg.

It has been working fine on my desktop, using an Apple 
cinema display, 1920 x 1200 pixels.  Recently I 
liberated a second display.  I'd like to use them 
together, particularly for SPFLG. Putting them 
together, I have an effective monitor size of 3840 x 
1200.  I believe this is still significantly smaller 
than what Frazer is using with his big monitor (??)


When I start SPFLG and only one monitor is attached, 
it works fine. However, when I start SPFLG with two 
monitors, it comes up looking like I have it in zoomed 
mode - letters are large, and text goesdisplay region 
is also zoomed.  If I then remove one monitor, nothing 
happens - the zooming of the text stays.  I think the 
display of the data is not zoomed.

I thought this might be related to not having enough 
shared memory available.  When I started this, I had 
shmmax set to 16777216. However, for 2 monitors, I 
need more than 2 x 1920 x 1200 x 4, or more than 
18,432,000.   So, I reset the shmmax to 33,554,432.  I 
believe this meets all requirements (integer multiple 
of 4096 (= shmall), power of 2, bigger than needed for 
number of pixels). However, it doesn't fix the 
problem.  (Yes, I rebooted after changing the shmmax, 
and yes I checked that I typed the number correctly 
and that the number was changed at reboot.)

Can you help?


[I also have a problem with the window not showing on 
both monitors.  That is, if I take a window - it can 
be the message window, the tv window, or the xterm 
window where I'm typing AIPS commands, and move it so 
it straddles the monitors, the minority part of the 
window is not visible.  This part does not appear to 
be AIPS - it happens on my laptop also, when not 
running AIPS.   But I wonder if it may have something 
to do with why the window is acting peculiarly across 
two monitors.]


Also, I remember that there is a way to change the 
display size of the text on the TV, but I am not 
finding in my notes how to do that and haven't found 
it in the help files.  Can one of you remind me how to 
change the text size?

Thank you,
Susan
