Sometime in the last few weeks, a Fedora 35 PC that uses the NVIDIA drivers lost use of its virtual consoles. By this I mean that if I switch to a VC with <Ctrl-Alt-Fx>, a getty service is started but I don't see any video: both of the two monitors just go to sleep. Evidently this has been a common issue with the NVIDIA drivers over the years but this is my first time to experience it. [root@calvin ulrick]# rpm -qa 'kmod-nvidia*' kmod-nvidia-510.60.02-1.fc35.x86_64 kmod-nvidia-5.17.8-200.fc35.x86_64-510.60.02-1.fc35.x86_64 kmod-nvidia-5.17.9-200.fc35.x86_64-510.60.02-1.fc35.x86_64 kmod-nvidia-5.17.11-200.fc35.x86_64-510.60.02-1.fc35.x86_64 Boot command line: [    0.000000] Command line: BOOT_IMAGE=(hd4,gpt2)/vmlinuz-5.17.11-200.fc35.x86_64 root=UUID=1a53e9b9-b298-4dab-8dbe-732b418b4d75 ro rootflags=subvol=root rhgb quiet rd.driver.blacklist=nouveau modprobe.blacklist=nouveau video=efifb nvidia-drm.modeset=1 acpi_enforce_resources=lax selinux=0 # lspci|grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GP107GL [Quadro P400] (rev a1) # lsmod|grep nvidia nvidia_drm             73728  6 nvidia_modeset       1167360  7 nvidia_drm nvidia_uvm           1204224  0 nvidia              39153664  342 nvidia_uvm,nvidia_modeset I added video=efifb just now. I also tried removing the acpi_enforce_resources=lax parameter and replacing nvidia-drm.modeset=1 with nomodeset. I also ran 'depmod -ae' in case I was affected by that issue. None of these fix the issue. Any suggestions on how I might proceed with troubleshooting this issue? Thanks, Dave
