I am trying to install CentOS 7 on a Dell Precision 3640 and am having some driver problems. I had to use kmod-e1000e from ElReo enable networking on the: 00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (11) I219-LM [8086:0d4c] I still don't have graphics. When starting Gnome, it shows the graphic screen briefly but reverts to the text login. It has two graphics cards: 00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9bc5] (rev 05) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

Dell has a Radeon driver for RHEL 8, but not for 7. I have no xorg.conf file.
