Revert commit : be5a7aa - (Add 1080p120 mode) Having a 120Hz modeline causes incorrect mode selection by the GUI / Display Manager, causing a 60Hz monitor to try with a 120Hz mode - leading to a blackscreen at graphical startup. The only fix seems to be having a xorg.conf in /usr/share/X11/xorg.conf.d/ Disabling for now to test fix.
Try using MODE_TYPE_PREFERRED in ps4_bridge.c, only for the 1920x1080-60 Hz mode. This may allow using higher display modes and refresh rates (60Hz vs 120Hz) without compromising on support for older monitors and lower resolutions.
