: My question is that, will only updating of "scrdev" global variable to
: adopt to new addr, size and color scheme etc will do the job or some
: other additional initialization are also needed to happen before it
: (nano-X) starts using the new video page?


If only psd->addr changes, you should be fine.  If psd->size
changes, then there could be a number of issues, including
recalculating all clip rectangles for the screen, to be considered.
Generally changing the size of the displayed area isn't currently
considered by any code, and many changes may be required.
Same for the color scheme.

Regards,

Greg
