That is, this may be due to hardware, but if we don't know what it is...

Start the program from a terminal and see if there are any messages when it takes a long time to slow down. Is it every program that does this? And GNOME 3 is heavy, no doubt about that.

Does the problem occur in the live environment?

What is the output of:

Code: Select all

lspci -knn|egrep -iA2 'vga|3d'

Does that also happen in a live version of Debian GNOME?

That's actually what I wanted you to try in the first place but never mind...

OK, fair enough.

Run Iceweasel from a terminal and see if it returns any error messages when you attempt to close it.

Are you running out of memory or using excessive amounts of swap when your desktop is slow?

Code: Select all

free -h
Is your drive full?

Code: Select all

df -h
Are you sure you have the correct NVIDIA driver?

Have you tired the Nouveau driver?

You could try following the systemd journal messages as they are written and see if anything shows up when your desktop is lagging.

Code: Select all

# gpasswd -a <user name> systemd-journal
# newgrp systemd-journal
journalctl -xf

See what processes are running and what useless ones can be stopped from your system control panel. But be warned that lot of stuff cant be turned off from there.
To actually see whats running, from a rooted terminal app or VT you need to type - ps aux
You can also run - top : to see what are using the most resources.
(I am nit sure if using sudo with these commands would permit system wide access).

I use KDE here, and can double its speed by disabling Nepomuk and the other PIM utilities that I never use. On an ancient system its completely usable.

You might want to try googling "optimizing gnome3"
This might help:

Also: see if you really need 3D acceleration required for a Gnome3 desktop. It eats up alot of system resources.

Yes -- GNOME shell requires 3D acceleration to start (the "on no!" message shows otherwise and the fallback desktop is loaded).

For comparison sake, try installing and using a light window manager like IceWM or fluxbox.

Do you have your system running for a long time?

GNOME shell has had a suspected memory leak for a long time and I think you are seeing the results of this in your system.
https://bbs.archlinux.org/viewtopic.php?id=186704
https://bugzilla.redhat.com/show_bug.cgi?id=977387
http://askubuntu.com/questions/557088/g ... nome-shell

Use ps_mem to confirm the source of the excessive memory consumption as GNOME shell and maybe try disabling all of your shell extensions to see if this improves the situation (other suggestions in the linked threads).

Otherwise, maybe try XFCE or LXDE instead...
