Just to confirm that i have same problem: OpenSuse 11.4 64 bit, NVidia drivers 270.41.06-5.1

Here is an output for 5 days of standard usage:

XOrg: 29436K / 75625K / 241952K / 313420K / 371412K
Plasma desktop: 29788K / 81688K / 88208K / 89252K /93828K
Kwin: 31188K / 36984K / 37708K /50812K / 58028K

Even if I do nothing at all allocated memory gets bigger. I'm using NVidia drivers 270.41... provided via Yast repositories. When I logout or restart system memory usage drops to~25000K, but after 3 - 4 days it gets too slow to work with, even with 8GB RAM on 6 core CPU.

These processes listed, after 3 days, are the top memory consumers.

I'm experiencing similar symptoms with a partially same setup.
Nvidia 9600GS with current (270) driver. xorg process starts out about 200M but steadily climps and after a day or 2 hits a gig. Unfortunately if I then run out of memory, xorg is targetted by the kernel for a kill and I lose my session.
Previous to 11.04, if i ran out of ram it would kill Firefox or some other application, and leave my session running. I can only assume that the reason for xorg being targeted is the amount of memory it is using (ideally the kernel should pop up a dialogue under memory limit conditions giving the opportunity to decide which app to kill... or at least know that x isn't a good choice).
Suffice it to say, this is a rather destructive bug. I don't much like losing work due to an X session ending.

I'm having the same problem on Ubuntu 11.04 64b with Gnome 2 and the proprietary nVidia drivers for a nVidia 9600 GT. I've also tried the latest nVidia and X versions from the xorg-edgers PPA, but to no avail. The Xorg process starts at ~50MB and after a while it randomly jumps to 500-700MB in a matter of minutes. There doesn't seem to be a certain program that causes it. Closing all of my programs doesn't solve anything, but a log-out does (I'm guessing it restarts the X server). I'll be happy to post any logs if someone is interested.

Same problem on Kubuntu 11.10 64bit.
Nvidia Go7400 with current (280.13) driver.
The Xorg process takes up 700~800MB memory after a few hours.
