Catalyst 10.1 and Xorg 7.5 / 1.7.x?

[energyman]

I may add that I'm running fglrx on mobility radeon 3650 with xserver 1.6.3 and synaptics are there and working.
So, it's not that You need 1.7 to have synaptics

P.S. I just can't figure out (didn't try much) how to improve performance with fglrx in KDE4...

that is X fault. X was broken for Intel graphics. If you want a fast desktop, you need to unbreak X. After doing that, it flies.

Search for
xserver-xorg-backclear.patch

get the sources for xorg-server, patch them, compile them, install them. Very easy with gentoo. If you are using something else - search your distros forums/mailing lists. I am sure somebody has done something about it.

Of course you can run older synaptics driver versions. I have a newer type of synaptics touchpad and need the newer driver for full functionality.
