If I click the logout button in gnome the "fading feature" will take forever
and I can watch every individual pixel getting dark on my screen. I'll have
to wait almost one minute until the logout confirmation pops up.
This special effect makes no sense on an unaccelerated server (framebuffer
in my case).
Can you give some more details of your X configuration?
Is this using the 4.0.x or 3.3.6 server?
What video card?
It is hard for me to imagine taking the effect taking a minute to run even
with no hardware acceleration at all.
I just checked it again under beta5: It takes precisely 47 seconds.
XF 4.0.1 FB server (from 4.0)
VGA=791 (1024x768 @ 16bpp)
Lynx SMI 910 chip
Here's a workaround - in /etc/X11/XF86Config-4, in the Driver
section, add the line:
Option "ShadowFB" "off"
It turns out that the problem is a bad interaction between the
frame-buffer shadow code and the way I do the iris effect.
Are we planning to make this automatic? Should this bug move to Xconfigurator?
Sorry - I've already worked around the problem a couple of weeks
ago in gnome-core, by doing the logout animation in a different
way but forgot to close the bug.
