Black screen after installation, only work after set nomodeset

Hi guys, recently I’ve installed manjaro KDE latest in an old machine, a samsung qx410 with hybrid card (use a dgpu GeForce 310M)…first, running using the live image works correctly, even seems to have video acceleration, but after install and reboot my machine I get a black screen (I’ve tried both installations, with/without privative drivers) the only way where I can run the OS is set nomodeset but the performance is terrible bad…

what could be the best approach here?..what drivers must I enable in order to have a better performance???, I don’t intend to play games in this machine but I need video acceleration because if this is disabled the OS feels so buggy and laggy

thank you so much guys
