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).

Comment 1 Owen Taylor 2000-07-19 19:33:29 UTC

Can you give some more details of your X configuration?

Is this using the 4.0.x or 3.3.6 server?
What CPU?
What resolution?
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.

Comment 2 Gerald Teschl 2000-08-02 11:12:46 UTC

I just checked it again under beta5: It takes precisely 47 seconds.
XF 4.0.1 FB server (from 4.0)
CPU=PII 300
VGA=791 (1024x768 @ 16bpp)
Lynx SMI 910 chip

Comment 3 Owen Taylor 2000-08-03 15:03:46 UTC

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.

Comment 4 Dale Lovelace 2000-08-19 19:28:15 UTC

Are we planning to make this automatic? Should this bug move to Xconfigurator?

Comment 5 Owen Taylor 2000-08-19 19:50:31 UTC

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.
