Não é possível iniciar o steam / tf2 usando nouveau

Question

Tentar usar o driver nouveau é a causa do mau desempenho do driver nvidia, mas não consigo ativar o vapor para usar o cartão dedicado.

Lançamento como env DRI_PRIME=1 steam steam://rungameid/440

Dê uma chance a isso.

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' steam

Espero que ajude.

O Steam possui sua própria biblioteca de tempo de execução. Você pode encontrar mais informações Arch Wiki

Ironicamente isso também funciona com o Ubuntu.
