maybe I did not explain clear of my problem
I run a program on kindle , the main task of the program is serialization a binary dict,
when idx of dict > 210000, it crash, if 180000>idx>210000,it works, but can not call other functions after serialization , (got an error message: memory address is out of range) that is why I want to as much as possible to save memory(not storage space), to test what is highest index of dict can be run on kindle , anyway, that is a strange requirement

However, deleting it has no effect, except from you having no screensavers
Also, if you want to change the screensavers, I do not recommend directly putting pictures there, but using the screensaver hack (linkss), which symlinks the images so that overflowing the root directory will not result in a bricked kindle
Edit:
If you actually meant ram, you are probably running a large ram-eating program.
If you want to know, you can stop the screensaver using helper+ in kual.
Executing "stop lab126_gui" in a shell will halt the user interface, freeing ram.
Also, you can create a swap file described here to gain more ram from the flash drive |
thanks, theol0403, found screensaver path as you mentioned:/usr/share/blanket/screensaver/, each image size is around 400k
if I was can delete them It would be saved 400k memory during kindle halted
I would not stop the screensaver using helper+, because my program running progress is very long, I need put kindle to my pocket, I mean I just need a blank screensaver
my pc connect kindle by USBNetwork Hack， it looks no permission to delete any file in /usr/share/blanket/screensaver/ path, do you know how can I get permission of this folder and delete those images? thanks!
