Topic: touchscreen woes
i am unable to calibrate my touchscreen. the unit does not respond to my touch....though it does respond enough to get me into "special options" screen when I touch the screen at startup, which leads me to believe that the internal connection to the screen is fine. i have tried the ts_settings posted on the chumby tricks wiki page to no avail.
at this point, i'm kind of stuck as I don't have wireless configured just yet, so i'm unable to drop down to a shell via ssh. i've tried attaching a usb keyboard as well but how do i get it to go the console instead of starting the control_panel?
i've opened up the unit, and taken out the microsd, and the partitions appear to be as follows (and nothing seems to be corrupted).
/dev/sda1 - boot loader i'm assuming. can't mount it since it's probably not ext2/ext3/ext4
/dev/sda2 & /dev/sda3 - both contain the same size filesystem and same data. which one is considered the "primary" OS partition? sda2 or sda3? i am assuming they are replicated such that if one gets foobar'ed, the device can be booted off the other. is that correct?
/dev/sdb4 - psp data among other things. i've tried nuking this partition completely to start from scratch so that the defaults get restored, but still the touchscreen doesn't calibrate. if i delete this partition , it gets recreated at boot time by chumby scripts with the remaining space available.
Please help! i am not quite convince the TS is bad since it does respond at boot time.
other things i've tried include loading up a armstrong silvermoon image, which works fine with a keyboard but my preference is to use the device as is for video playback for the kids .
thanks for your help!
