- I have tested a fresh installation (via usb-stick) of Kubuntu 12.04.x with nvidia driver 331.113-0ubuntu0.0.0.3 and 304.125-0ubuntu0.0.0.1 , but I cannot reproduce the problem there (a few hours of testing).
But with a fresh user on the affected installation, the memory leak occurs. - On my Office PC (12.04.x) with nvs300 the problem is gone, but I don't know why. (nvidia driver 304.125-0ubuntu0.0.0.1) There was a kernel update linux-image-3.2.0-75-generic, but I don't know if this is connected. I installed and reinstalled several times different kernels. changelog linux (3.2.0-75.110) precise; urgency=low [ Kamal Mostafa ] * Release Tracking Bug - LP: #1403154 [ Upstream Kernel Changes ] * kvm: fix excessive pages un-pinning in kvm_iommu_map error path. - LP: #1386395 - CVE-2014-8369 * KVM: x86: Don't report guest userspace emulation error to userspace - LP: #1392823 - CVE-2014-7842 * drivers:scsi:storvsc: Fix a bug in handling ring buffer failures that may result in I/O freeze - LP: #1400289 * net:socket: set msg_namelen to 0 if msg_name is passed as NULL in msghdr struct from userland. - LP: #1335478 -- Kamal Mostafa <[email protected]> Tue, 16 Dec 2014 10:00:12 -0800 - On my Home PC (GT 430) the problem is still there; That's why I have upgraded to the latest Ubuntu LTS version 14.04.x There I installed the Utopic(14.10) kernel (3.16) with the Utopic xstack (Xserver 1.16.x) with latest nvidia 346.35 driver (with the default settings), but still the problem, but now with a crash after growing of kwin and xorg.

In one hour the memory consumption is at Xorg ~ 270 MiB and at kwin: 300 MB , so the system responds slowly and scrolling is very slow in in dolphin, kwrite, firefox, etc. After several hours the system is so slow, that only a restart helps, and then the growing of memory starts again. *** My Tests; I tried several nvidia drivers, but without success (from: https://launchpad.net/~xorg- edgers/+archive/ubuntu/ppa/+index?field.series_filter=precise) 304.125-0ubuntu0.0.1~xedgers12.04.1 331.113-0ubuntu0.0.1~xedgers12.04.1 346.22-0ubuntu1~xedgers12.04.1 (With purging each nvidia driver and fresh installing it) *** My configuration; Two Kubuntu 12.04.5 PCs with a nvidia card; nvidia driver 331.113-0ubuntu0.0.0.3 and 304.125-0ubuntu0.0.0.1 One pc with the Trusty Xstack (HWE) with Trusty kernel (3.13.0-43.72~precise1) and the other one with the stock kernel (3.2.0-74-generic #109) and stock xstack. I use one pc in my office, so it disturbs my work because of the slowness and restarts. Thank you for your help!
