xorg error after xorg upgrade to rawhide and downgrade to f10

[maggiolo00]

Hi, I have just downgraded my xorg server (and related intel drivers) from rawhide repository. In this two processes i have erased and reinstalled many packages (all my kde installation was erased!!). Now i m able to start Xorg only with vesa drivers and when i try to start a graphic application from terminal i recevie this error

Xlib: extension "Generic Event Extension" missing on display ":0.0".


i have to install some additional packages ?

EDIT : All is fixed. Removing all rawhide packages from my system fix X11 and intel driver works again
