I now use XIPNKPC4_CORE_CF35_120416. In this version, is activated for me the first time, the 2D hardware acceleration. Now the LCD flickers at me sporadically, if contents are redrawn. In this short time the screen goes black. I turn off the acceleration, the screen no longer flickers. But after a restart, the acceleration is always enabled.
What can be wrong?
Or how can I disable the 2D Bescheunigung permanently?
Hello,
"HKLM\drivers\display\lcd\accellevel=Dword:1" disables 2D HW acceleration.
Did you try to use latest kernel?
Quote from "fs-support_ZU"Did you try to use latest kernel?
No, I have not tested.
In "history.txt" is not a change for 2d acceleration listed. Why should it work better?
You are right.

This setting will produce no results!
If i use verbose, i can see the following debug-info:
Here is the part of the registry:
Hello,
you are right, it does not work there must be a bug in the display driver. We will rework this feature for the next kernel release.
If it is possible for you, you can set color resolution to 8 BPP in the meanwhile. In this case no acceleration is used.

Is this corrected in the Beta "XIPNKPC4_CORE_CF35_120709_BETA.zip"?
No, sorry this kernel does not include the feature for set "AccelLevel".
The feature is planned for the next release.
Why the LCD flickers?
It may actually not be that only I have these problems.
Can i control the 2D-Acceleration directly?
Just like you, with your 2d-control settings?
Hello,
best would be you wait for the new release please, i can not give you a fix date. If it is urgent contact our sales office.
You may try this http://www.forum.fs-net.de/viewtopic.php?f=4&t=2655 (call ExtEscape). I did not test it on PicoCOM4!
QuoteWhy the LCD flickers?
Because some acceleration features are buggy programed by the chip manufactor!
