Linux OS GUI is inaccessible for AMD based servers when changes are made in the grub file.
by Malka Adithya from LinuxQuestions.org on (#6K4KF)
My Linux OS has the iommu in turned ON state by default in the kernel. But, When I am adding the line "iommu=pt amd_iommu=on pci=assign-busses" in GRUB_CMDLINE_LINUX inside the vi /etc/default/grub file it is making my Linux OS GUI inaccessible. Can Someone please explain me the reason for this. Thanks in advance:).
