Question

I installed dota2 in linux, but in the main one I start it only by turning off the other monitor, can anyone know how to force the game to start on the main monitor?

Answer 1

On Linux, none of the developers really test games, because according to statistics (click OS Version), only 0.81% of gamers use it in 2019. So if a bug has surfaced, then its developer may not fix it even after a complaint and a detailed description.
In any case, a question about a game on Steam is more likely to get a normal answer on the game's forum (a separate forum or discussions on Steam).
