Oh! Are you using tslib? I think you need this: module_raw input module pthres pmin=1 module linear And you need to calibrate the TS. Perhaps this is the problem? # cat /etc/pointercal 557 38667 -4654632 -51172 121 46965312 65536 This test application should help: http://svn.openmoko.org/developers/tick/touchtest/touch_test.py >>> I hope someone who is familiar with the new touchscreen filters can help us. >> Where's the code?

Here it is: > http://git.gnufiish.org/?p=gnufiish.git;a=blob;f=arch/arm/mach-s3c2440/mach-glofiish.c;h=bdf4d1e2d235a47ddc0c282d33fd7df1fa94036a;hb=HEAD I noticed you're using an old version of the code. The configuration was simplified. Latest versions: http://git.openmoko.org/?p=kernel.git;a=tree;f=drivers/input/touchscreen;h=82c404c966af0b6e985917e3b8fba06eb7385d4d;hb=andy-tracking (this was the last change / dirty patches with style fixes included...). http://lists.openmoko.org/pipermail/openmoko-kernel/2009-March/009450.html You might want to check mach-gta02.c also. But again, I think you have to make the driver work before using the filters. > Will try and report. I didn't understand the report you sent. I think you could listen to the events and show them as they are reported.
