Created attachment 1119340 [details] /etc/X11/xorg.conf generated by nvidia-settings using a BaseMosic 3x2 layout for 2 NVS 510s Description of problem: On RHEL 7.1 once gdm starts gdm ignores system xorg.conf generated by nvidia-settings and mangles the display layout. The attached xorg.conf was generated by nvidia-settings using BaseMosaic to for 2 nvidia NVS 510s creates a single X server that spans across mutliple GPUs in a 3x2 layout (7680x2160). gdm reconfigures the display layout (show in Xorg.0.log and :0.log) to a single row of 6 displays (6x1 at 15360x1080). Using startx from a multi-user.target or a different desktop manager (xdm or lightdm) does not reconfigure the layout Version-Release number of selected component (if applicable): RHEL 7.1 gdm-3.8.4-32 How reproducible: Always Step to j Using the attached xorg.conf with supported nvidia GPUs enable gdm and start the graphical.target Actual results: Once gdm starts, the displays are not in the expected 3x2 layout configured in /etc/X11/xorg.conf. gdm reconfigures the layout to be a single row of displays. Expected results: gdm to use the /etc/X11/xorg.conf BaseMosaic 3x2 metamodes.
