I had this problem as well and found the following hints by smagoun at
https://code.fluendo.com/elisa/trac/ticket/1165:

I ran into this problem with Elisa 0.3.5 on a Beta build of Ubuntu
Mobile (Hardy). Creating ~/.elisa/elisa.conf allows Elisa to start, but
it ran slowly and flickered.

Turns out the problem was a permission problem on the X server - DRI was
only enabled for root, so elisa's benchmarking code failed. The
benchmarking code only runs if ~/.elisa/elisa.conf doesn't exist(??),
which is why the above workaround works. The flickering is caused by
software rendering.

When I ran 'elisa --benchmark' on the command line I noticed the
following, which indicates the DRI permission problem: libGL error:
failed to open DRM: Operation not permitted libGL error: reverting to
(slow) indirect rendering

In my case the fix was to add this to xorg.conf:

[code]
Section "DRI"
    Mode 0666
EndSection
[/code]

Elisa won't start - your graphical hardware is not properly configured to 
support 3D software such as Elisa media center
