I don't really remember what I did, but after I used AVN (Avant-windows-navigator) it crashed together with compiz-fusion, and now whenever I run compiz or compiz --replace, it won't work, windows decorations just dissapear (no decorated frame around windows) and no 3d effets either.
here's the output from "compiz --replace"
Code:
libGL error: drmMap of framebuffer failed (Invalid argument)
libGL error: reverting to (slow) indirect rendering
compiz (core) - Fatal: No GLXFBConfig for default depth, this isn't going to work.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0
I also installed some updates before that, but I can't recall which ones I installed.
Using Mandriva 2008.0, KDE 3.5.7, Compiz-Fusion, Mobile 915GM/GMS/910GML Express Graphics Controller
