Now tested with following hwpack and rootfs: http://snapshots.linaro.org/precise/hwpacks/lt-panda-x11-base/305/hwpack_linaro-lt-panda-x11-base_20120912-305_armhf_supported.tar.gz http://snapshots.linaro.org/precise/images/ubuntu-desktop/412/linaro-precise-ubuntu-desktop-20120912-412.tar.gz
I tested textures demo and added one debugging log to http://pastebin.com/9VjcHzmt I think this backtrace is the most relevant part of the log: (gdb) bt #0 0xb6df9b38 in QEglContext::chooseConfig(QEglProperties const&, QEgl::PixelFormatMatch) () from /usr/lib/arm-linux-gnueabihf/libQtGui.so.4 #1 0xb6fb3a1a in QGLContext::chooseContext(QGLContext const*) () from /usr/lib/arm-linux-gnueabihf/libQtOpenGL.so.4 #2 0xb6f8798e in QGLContext::create(QGLContext const*) () from /usr/lib/arm-linux-gnueabihf/libQtOpenGL.so.4 #3 0xb6fb3bf0 in QGLWidget::setContext(QGLContext*, QGLContext const*, bool) () from /usr/lib/arm-linux-gnueabihf/libQtOpenGL.so.4 #4 0xb6f87026 in ??
