Public bug reported:
Binary package hint: xubuntu-artwork
With no accelerated SVG implementation for ARM at present, this is
causing a delay of about 1 minute between gdm startup and displaying a
login box on an 800 MHz ARMv7 platform. This at least doubles the time
from boot to a login prompt on this platform.
By contrast, scaling a 1680 x 1050 .png to fit the 800 x 600 screen size
(as done in the previous xubuntu-artwork) gives a much faster gdm
startup time (start of execution to display of login box) of about 6
seconds. I've tested this by editing
/usr/share/gdm/themes/xubuntu/Xubuntu.xml to change the background image
file and leave everything else the same.
Ideally, this kind of bulk SVG graphics rendering should not be on the
boot+login critical path, the rendered image should be persistently
cached, or there should be a way for the default backdrop to fall back
to another (probaly png or jpeg) format for selected platforms such as
armel.
