Viewing X Resource usage: xrestop

• Some client requests allocate resources in the X server: pixmaps, GC's, colormaps, etc.

• Failing to call the corresponding Free* requests causes people to think their X server has a memory leak when it's really a client not cleaning up its mess

• xrestop provides an updating view of how many resources each client currently has allocated

• http://www.freedesktop.org/wiki/Software/xrestop

• Requires X-Resource extension

  • Found in Xfree86 4.3+, Xorg 6.7+, and Solaris 9+ Xsun
