Non-linear pointer moves
From the QtMoko Report announce:
Currently the Qt-Embedded deb installs itself into /opt in order to not mess, or conflict with the non-embedded Qt variant provided by Debian. There are demos installed to /opt/qt-embedded/examples, and I did try out a few of them. They appeared to work properly, but there is a problem with touchscreen input: When touching the screen, Qt properly detects a mouse-press at the right location of the screen. But then when moving the pointer, it runs away in a non-linear fashion. I later concluded that it looks like this: pos_new = new_absolute_coordinates + distance_to_last_position This is a serious issue and needs investigating. We suspect that the Qt-Embedded LinuxTP mouse driver is doing something nasty!
If you want to play around with it, this is how:
# set up environment export PATH=/opt/qt-embedded/bin:$PATH export LD_LIBRARY_PATH=/opt/qt-embedded/lib:$LD_LIBRARY_PATH export QWS_MOUSE_PROTO=linuxtp:/dev/input/touchscreen cd /opt/qt-embedded/examples # try out whatever example you like, and dont forget to pass the -qws commandline option
