Not necessarily. The X server could be allocating those resources on behalf of any client, including KDE's plasma desktop. I had similar issues with Plasma Desktop 4.7 when restarting it worked as a stop gap solution for me. Haven't encountered the problem in 4.8 yet though. > I'm not encountering the > issue you mentioned, but Xorg uses 32MB of memory (and 35MB shared mem) on > my system. > > I don't know how to debug/resolve this (memory leak) issue, but you > probably have to supply the following items: > - total RAM in your system > - Xorg version you're using > - Exactly which driver you're using + version > - Archive(s) you're using (you said _kde_ from sid, but what about the rest > of your system?) It could also be a matter of chosen compositing settings, e.g. using OpenGL and having a leaky OpenGL implementation. In such a case switching to the XRender backend might improve the situation, or the other way around, or course. Cheers, Kevin
