Full Version: Screen Ghosting
OESF Portables Forum > Everything Else > Archived Forums > Distros, Development, and Model Specific Forums > Model Specific Forums > Sharp Zaurus > Cxx0 Hardware
Recently I reflashed from pdaxrom to Cacko 1.21b, but discovered that the screen appeared ghosted. So, I did a NAND restore to the original ROM and there was no ghosting effect. So, I converted the ROM to English. I don't have ghosting effect in pdaxrom either.

What causes the ghosting effect in Cacko? How can I get rid of it?

What do you mean by that? More info, please!
OK, type this at the console:

su <enter> to become superuser then

echo 75 > /proc/driver/w100/fastsysclk <enter>

the screen will flash and the ghosting will be gone, but it will come back again when you reboot. I think you can add the line to to automatically set this on bootup.

The problem was the screen refresh rate being set wrong, the above command sets it to 75, I have the same problem on cacko the last few weeks since i reflashed....
I flashed the C760 I just received with Cacko 1.21b and I had major ghosting. The procedure provided by Anonuk was the fix. I now just need to make it happen at boot. Thanks for the tip.

SL-C760, Cacko 1.21b

This doesn't apply to Cacko. And actually, it didn't fix the jittering problem for me (in pdaXrom).
The thread mentioned above applys to all Zaurus "ROMs" - it basic hardware changes - anyone with shadows/ghosting/flickering should try the D+M menu settings first - after trying 3-4 times i got my settings just perfect - this also works when running Cacko - in particalur its the C860 series thats affected the most.
