C860 Stylus, Not stable? READ THIS Options

[Dima202]

Okay, if your stylus is constantly moving and not accurate.
Thanks to pgas, here is how to solve the problem:
<pgas> /etc/sysconfig/clamshell/scripts.d/x11scr
<pgas> in this file
<pgas> there is echo "100" >/proc/driver/w100/fastsysclk
<pgas> change the 100 to 75
<pgas> ie echo "75" instead of echo "100"

This should do it!

THANKS PGAS!!!!

wow - that's made an enormous difference! I didn't have a wandering pointer, but I thought that I had damaged the touch-screen by fitting a screen protector, because pointer positioning around the top right hand side was very inaccurate. Instead, the problem must have coincided with an update of the ROM. It is now so much better on complicated things like ko/pi. Thank you!

This must be included in the next release...

and how to change it on other devices? I have a C3100 now with beta4 but the pointer was always moving a bit and not accurate.
In the X11scr there is nothing like this to change...

Please help...

On Tosa the jumpy cursor always gets worse when you overclock. On a lark, I decided to try and adapt the info in this post, and the result is nothing less than amazing!

echo "400" > /proc/driver/ts/wait_vga

Now the cursor jumpis barely there.
If I return the CPU to normal speed, then the cursor jumps quite a lot. The solution is to return to the original value.

echo "25" > /proc/driver/ts/wait_vga

Some investigation into this would be worthwhile. Perhaps the results could be incorporated into the overclock utility to provide the most stable cursor at any speed.
