There are these FOSS drivers available for NVidia graphics:
FBDEV VESA Nouveau DDX Modesetting DDX
I think I find the nouveau driver. On my host, I have the packages
libdrm_nouveau2-2.4.97-lp151.1.1.x86_64 libdrm_nouveau2-32bit-2.4.97-lp151.1.1.x86_64 libvdpau_nouveau-18.3.2-lp151.22.4.x86_64 Mesa-dri-nouveau-18.3.2-lp151.22.4.x86_64 Mesa-dri-nouveau-32bit-18.3.2-lp151.22.4.x86_64 xf86-video-nouveau-1.0.15-lp151.4.1.x86_64
xf86-video-nouveau is the DDX. DDX is the competent X driver foundation. Which other bits are used depend on which foundational selection is enabled.
I did not install any of them manually, either they already were present with 15.0 or they werde added with the upgrade to 15.1.
Modesetting seems to be included somewhere. Ah, yes. rpm -qf /usr/share/man/man4/modesetting.4.gz xorg-x11-server-1.20.3-lp151.3.1.x86_64
Modesetting is the default competent FOSS foundation. ...
xrandr is confused and tells me I got 2 screens, attached via HDMI-I (1920x1200+0+0) and DP-1 (1920x1200+1920+0). Quite false, there is only one HDMI cable attached, and KDEsettings tell me 3840x2160. ... I'm using 2 x 1920x1200 (24") screens here now... with Intel "HD Graphics 630", Driver i915, BTW.
I am confused too. Only a HDMI cable, but two 1920x1200 screens??? i915 is a kernel driver. The issues with black screens are usually about DDX drivers when only FOSS is installed.
This is what xrandr tells me at home. Obviously, xrandr is confused. I'm using one screen with a resolution of 3840x2160 at home. Neither xrandr's number of screens nor its resolution matches reality. The output of xrandr at the office and at home are the same, I just see, just some decimals at the given resolutions differ... The Esprimo's xrandr even tells me about DP-1 and -2 and HDMI-1 and -2, when there ist only one DP and one DVI connector.
When there are two screens, and one or both are black, it's sometimes a result of server mixup, lighting up only a secondary screen on which a mouse pointer can be made to appear.
In my case (at the office), the monitor connected via DP remains black on startup ("no signal"). If I switch it off, and on again when initrd shows "switching root...", I get a wonderfult 2 screen display. But that's at the office, with the Esprimo, containing Intel graphics. The late picture on DP if used together in a 2-screen-solution is known in the company to occur also with windows. Seems to be a hardware thing.
Last I saw something like this was last month. A local gamer bought a new PC with a new screen. Contrary to the bold text in the quick connection guide, he hooked up both DVI and DisplayPort cables to both the gfxcard and the single display. Windows dutifully made the desktop 3840x1080, but the single display only showed the right half. The mouse pointer could be seen at top, bottom and right edges, but only after moving it to the right, off the primary/left/invisible/missing screen "connected" to the DVI cable.
You can use xrandr under Linux to switch monitors like you want them. Sometimes it takes a while until you get what you want, but everything is possible :) But: there are no two monitors connected to my nVidia card at home. There only is one. At the office, I have 2 monitors, but an Intel grapchics chip.
How do you configure "modesetting" as the default driver?
