Eu recentemente habilitei libgl1-mesa-glx em vez de libgl1-mesa-swx11 . Agora, alguns programas (como waterfox) se recusam a executar porque lançam esse erro:
/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.21' not found
Eu não tive esse problema quando estava usando libgl1-mesa-swx11 (cerca de uma semana atrás) ()
