[maemo-developers] [maemo-developers] Unable to create virtual memory

Hi all,

I have Nokia 770 with OS 2006 on it. I've been trying to extend my 
memory card to be used as additional virtual memory. I used Control 
panel->Memory->Virtual (tag). When I choose either of sizes offered 
(from 8 MB to 32 MB in my case) and press 'OK' it displays an error 
window 'Unable to create virtual memory'. What might be wrong here? And 
also, what this built-in option actually does? Is it analogical to 
'swapon/swapoff' terminal command and, thus, the screenshot applet? Do I 
have to create manually a swap file before using control 
panel/screenshot applet?

My memory card has the size of 64 MB. It is currently 38% used and the 
rest of it is free. There is only one default partition.

My second question is whether to use swap file or partition? Did I 
understand correctly (http://maemo.org/maemowiki/HowTo_CreateSwap) that 
for OS 2006 there are basically NO arguments for using a swap partition 
rather than a swap file on the memory card? The only one I find is that 
a swap partition will be available when the Nokia 770 is connected via 
USB to a PC. Otherwise the OS 2006 automatically does swapon/swapoff 
upon USB connection/card ejection, so the device will not crash if we 
forget to do it manually.
