It seems that the flash plugin can't find some libraries, so I made some symlinks and it's working now. $ su # cd /usr/lib # ln -s /usr/X11R6/lib/libXt.so.6 libXt.so # ln -s /usr/X11R6/lib/libXext.so.6 libXext.so # ln -s libstdc++.so.5 libstdc++-libc6.2-2.so.3 per libstdc++-libc6.2-2.so.3, you can install compat-libstdc++ package instead of making a symlink.
