One workaround to get Qt 5 working with SGX is simply forcing just the pvr to
be loaded by Xorg, creating a specific config:
root@ubuntu-desktop:~# cat /usr/share/X11/xorg.conf.d/99-pvr.conf
# X.Org X server configuration file
Section "Device"
Identifier "Video Device"
Driver "pvr"
Option "FlipChain" "true"
Option "NoAccel" "false"
EndSection
Section "Monitor"
Identifier "Main Screen"
EndSection
Section "Screen"
Identifier "Screen"
Monitor "Main Screen"
Device "Video Device"
EndSection
Section "ServerLayout"
Identifier "Server Layout"
Screen "Screen"
EndSection

Title:
QT5 based applications fails with a segmentation fault with Pandaboard
and the SGX driver
Status in Ubuntu OMAP4 graphics addons:
New
Status in “pvr-omap4” package in Ubuntu:
Confirmed
Bug description:
While testing Qt 5 support on Ubuntu, and validating the support for
OpenGL ES2.0 with Pandaboard, I couldn't start Snowshoe (Qt 5 - webkit
based browser) as it gives a segmentation fault and also breaks the
X11 server (with the pvr driver).
After a quick check with Snowball (Mali 400), it worked properly and
as expected, so this could probably be related with the current SGX
driver available for Pandaboard.
How to reproduce the issue:
1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily
2) Install 'snowshoe-mobile' package
3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe
This is with Ubuntu 12.04 with pvr-omap4 1.7.10.0.1.21-0ubuntu1 (from
archive) and also 1.7.15.0.1.57-1 from TI's PPA.
