Acabei de atualizar para o CentOS 7.4 via yum update e reiniciei o novo kernel:
[root@rice ~]# uname -a
Linux rice 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Os gráficos não funcionaram após essa reinicialização, então eu reinstalei os drivers nvidia:
[root@rice ~]# yum list installed | grep -i nvidia
Loaded plugins: fastestmirror, langpacks, nvidia
kmod-nvidia.x86_64 384.69-1.el7_4.elrepo @elrepo
nvidia-detect.x86_64 384.59-1.el7.elrepo @elrepo
nvidia-x11-drv.x86_64 384.69-2.el7.elrepo @elrepo
nvidia-x11-drv-32bit.x86_64 384.69-2.el7.elrepo @elrepo
yum-plugin-nvidia.noarch 1.0.2-1.el7.elrepo @elrepo
[root@rice ~]# yum reinstall kmod-nvidia nvidia-detect nvidia-x11-drv nvidia-x11-drv-32bit
Reiniciando novamente, ainda não tenho sessão gráfica ativa.
Verificando os registros:

Como posso recuperar minha sessão gráfica?
Obrigado.
Eu decidi que há muitas coisas acontecendo no gnome para fazer da sessão do gnome uma boa plataforma de testes.
Eu instalei o vtwm e posso iniciá-lo com:
$ xinit $(which vtwm)
ele funciona bem, e eu posso abrir um xterm, lançar o firefox, etc., mas se eu tentar usar qualquer aceleração 3D, obtenho problemas:
[mgesing@rice ~]$ glxgears
Error: couldn't get an RGB, Double-buffered visual
[mgesing@rice ~]$ glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig
Eu tentei reinstalar o desk-libGL, o nvidia-x11-drv e o kmod-nvidia, mas ainda não sinto alegria no glxgears.
Eu suspeito que a falta de efeitos 3D pode ser o que está atrapalhando a minha extravagante sessão de gnomo. . . Algum conselho sobre como obter a aceleração 3D funcionando novamente?
