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!
