Graphics is therefore not working. I also looked into the Samsung Galaxy Tab 3 10.1 porting effort and they seemed to not have any problem with the GFX at this stage. They have SGX544, though. Any ideas? Does also not work without surfaceflinger patches (Open-GL ES1.1 fallback). The ValidateWindowConfigFormat errors are the problems, I think.
