RE: [linrad] Front end for Linrad
The next major step in Linrad development will hopefully be
a restructuring to a multi-threaded program. Once that has been
finalized it will become much easier to separate user control from
I do not use X myself but I think some people have managed to
get Linrad going under X while others have failed. I think
it depends on what svgalib driver has been used.
It should be possible to switch between Linrad and the normal X-screen
if you want to set parameters by changing the parameter files but
you should not do it while Linrad is running because the parameters
are read into memory when execution starts.
When changing mode parameters you can leave the processing with "X"
then change parameters and resume with "B". To change soundcard
parameters and other things in par_userint you have to go to the
main menu before changing.
Illegal parameter combinations will force the default parameters
or prompt to the parameter selection routine.
Since Linrad starts rapidly I use ESC to exit, then change terminal
with alt and a number 1 to 6 to get another terminal in which I have
parameter files in joe, my favourite text editor. Just type in the change,
save, alt back to where I run Linrad, press "l" to restart.
l is a symbolic link to linrad which resides in /usr/bin
