Troubles with Gnome update(to 2.26)


i’ve problem, after gnome update, from 2.24.1 to 2.26.

When my system loads, has a problem with the incompatibility with
XKB. Another issue is that when I turn the effects on the desktop, buttons, Minimize, Maximize and Close, in addition to the title bar does not appear.

Please, help

XKB error message:

It can happen under various circumstances:
- a bug in libxklavier library
- a bug in X server (xkbcomp, xmodmap utilities)
- X server with incompatible libxkbfile implementation

If you report this situation as a bug, please include:
