Hi list, I reinstalled on my workstation CentOS 8.1. I explain: I'm a KDE user but packages shipped from EPEL currently are buggy so I prefer a stable and functioning system to work with. So I tried to remove KDE workgroup and installed group "Workstation" but the system bricked so I reinstalled with GNOME. I've an nvidia gtx 1050ti GPU so I installed kmod-driver from rpmfusion. After the installation of Nvidia driver, I rebooted, gdm start and after I perform the login the system freeze. So this problem happened to me with C7.5 and nvidia driver. In my case I need to blacklist i915 module and system works. Also in this case I tried to boot centos changing grub kernel parameters pressing 'e' in the grub menu and adding "i915.modeset=0 rd.driver.blacklist=i915", booted and system works. So I tried to make this permanent updating grub configuration adding the previous directives (and removed rhgb and quiet) to /etc/default/grub and run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg. Reboot the system and checked again kernel parameters on grub menu and seen that nothing changed. Booted and freezed. I checked /boot/efi/EFI/centos/grub.cfg and kernelops has the new directives. Seems that grub configuration does not take effect. I made another test inside a VM installed with minimal selection and remove rhgb and quiet parameters and worked fine. The vm is BIOS and my workstation UEFI. How I can solve this problem? Currently to boot my system I need always to add this params. Thank you in advance
