Kernel Module VIDEO E-ink (Help build from sources)

[lexai]

Good day.

amazon kindle dx graphite

I use the server as a second monitor via a VNC

But the update speed is very small, for example 1/ per second

I believe that this can be changed in the device drivers, but I do not know how, because I am not able programirovat

I ask the experts to look at the sources of the device driver and say - can I increase the speed of updating the picture of e-inc.

Доброго дня. (Original in Russian)

amazon kindle dx graphite

использую через VNC сервер как второй монитор.

но скорость обновления очень маленькая, примерно 1 раз / в секунду

считаю, что это можно изменить в драйверах устройства, но не знаю как, т.к. не умею програмировать

прошу знатоков посмотреть исходники драйвера устройтства и сказать - можно ли повысить скорость обновления картинки е-инк.

As I understand it is only a demo..


I do not have such in-depth knowledge to "pull out" the source code from these demos((

Change your understanding.

Re-read about the hardware differences and how their operation is the limiting factory on the VNC frame rate.

Translation:
What you observe is not the driver's fault, it is inherent in the older hardware you are trying to use.

Either put up with it, or use newer hardware.
