[SOLVED] Slow cursor follow in Qt 5.2.2 (git) on freescale i.MX6 with tslib
-
Hi all, using qt 5.2.2 (release branch from git, but I noticed the same issue with 5.2.1) on I.MX6 it is impossible to flick on qml elements because the cursor does not "follow" the finger on touchscreen...
I am using tslib library because my touchscreen does not support evdev (it is resistive?).
The strange issue is that with non-qml application (fingerpatin example) or using tslib test application (ts_test) on device the cursor follow the finger at higher speed.
Is this a libqtslibplugin.so or a qml issue?
I generated the plugin without any option, only qmake, make and make install... -
Hi,
Since it's a bit low-level, I'd avise to post this question on the "interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest you'll find there Qt's developers/maintainers (this forum is more user oriented)

Thank you SGaist, I already send a mail!
I used this forum as first tier, in order to find simple answer in a fast way...
Do you advise me to post the answer in this thread? -
I solved the issue setting the maximum CPU frequency for my board with the command:
@ echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor@
Forgive me for this spam topic, reading the board documentation it was written that the maximum cpu frequency was the default value, but it isn't...

Don't excuse yourself for reading the documentation ;)
Thanks for sharing the solution, that might help other
