3D

なんか KDE 環境下だと全面的に 3D アプリが動かないんですが・・・

Compiz Fusion, Blender, K-3D, Supertuxkart, SuperTux2, Armagetron Advanced, BZFlag, ...
Compiz Fusion は知らないけど、他はみなこのエラーだ・・・

X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  135 (DRI2)
  Minor opcode of failed request:  7 ()
  Serial number of failed request:  27
  Current serial number in output stream:  27

GNOME では問題なかった気がする・・・
