recently i install deppin in my laptop hp 530. after the installation the screen is black. after many consultation in forums i found a temporary solution. to put in the grub bootloader i945.modeset=0 after this deepin start normally. but when i put i945.modeset=0 in the grub.cfg and restart the laptop and start deepin the screen is black again. the courious thing is that when i restart the laptop and i enter in edit mode of grub (pressing E) and modifying i945.modeset=0 by the same value i945.modeset=0  and press ctrl+X, deepin start normally. if anybody knows why is that, please let me know.
