ha, it's working now. don't know why.
exploring installing installing nvidia graphics card driver and also nvidia cuda, do not want to deal with elrepo and kmod stuff (for now) I feel more comfortable getting the .run files directly from Nvidia, which will support K, P, and V nvidia cards in servers.
What I did was
- install from7.6-1810 from dvd, on optiplex7010 test pc with k600 graphics card, server with gui, works fine on nouveau.
- modify grub command line to blacklist nouveau, reboot, graphics completely busted can't log in gaphically so trick is to
- systemctl set-default multi-user.target, then modify /etc/default/grub and do grub2-mkconfig, then reboot.
- reboots into runlevel 3, tried "systemctl isolate graphical.target;" and that failed gave some error so i did "nit 5" and that worked. This was after doing a full software update after dvd install.
- So i rebooted again, after installing nvidia and cuda .run files, cam into runlevel 3, installed NVIDIA-Linux-x86_64-418.43.run successfully, then rebooted, came into runlevel 3 I then used "systemctl isolate graphical.target" and it worked.
- then went back to run level 3 and installed systemctl isolate graphical.target
- as well as settings "fips=1 boot=UUID=blabla" and doing dracut -v -f" followed by another "grub2-mkconfig -o /boot/efi/efi/centos/grub2.cfg"
I am using successfully using
Code: Select all
GRUB_CMDLINE_LINUX="rhgb verbose rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nouveau.modeset=0 fips=1 boot=UUID=5ef7d520-7b65-4816-abff-85ad46533c36"
FYI... I think fips through a
/var/run/nologin into the mix causing
pam_nologin to take effect and could only log in as root afterward, until I deleted
/var/run/nologin
