Bug#790080: EGL, Qt and xvfb

Do you mean running an X server? Why would that be necessary? Could
the test be making use of an X server other than in the usual way,
through DISPLAY?
It is possible to run the test which is failing on arm* like this on amd64:
cd obj-*/autotests
DISPLAY=<host-running-vncserver>:1 ./kcolumnresizertest
Same thing doesn't work on arm64.
(The vncserver had "xhost +". Other tests in the same directory worked
on both systems when run like that. There were lots of differences
between the two systems besides the architecture, but both were Debian
unstable chroots.)
