Hi! I have a very strange situation after i updated my system to fedora 36:

the new 5.17.9-300.fc36.x86_64 does not boot or at least cannot start my monitor (i get on the monitor "no signal received")

while the identical fedora 35 one worrks 5.17.9-200.fc35.x86_64

having an nvidia card, i checked that i have kmods for both kernels

root@hal: entries # rpm -qa | grep kmod-nvidia

akmod-nvidia-515.43.04-1.fc36.x86_64

kmod-nvidia-5.17.9-200.fc35.x86_64-515.43.04-1.fc36.x86_64

kmod-nvidia-5.17.9-300.fc36.x86_64-515.43.04-1.fc36.x86_64

and my GRUB_CMD_LINE looks like this:

GRUB_CMDLINE_LINUX="acpi_osi='Windows 2013' acpi_enforce_resources=lax iommu=soft iomem=relaxed quiet mitigations=off libahci.ignore_sss=1 root=/dev/md1 rootfstype=ext4 selinux=0 rd.plymouth=0 plymouth.enable=0 rd.auto rd.md=1 rd.dm=1 rd.lvm=0 rd.luks=0 rd.vconsole.font=ter-v32n KEYTABLE=us LANG=en_US.UTF-8 rd.driver.blacklist=nouveau modprobe.blacklist=nouveau"

any idea why f36 kernel would not work and how can i troubleshoot this?

Thanks a lot!

Adrian

There was a similar thread earlier this month.  Try depmod, or dnf reinstall the nvidia packages.

thanks a lot! i'm not sure if "reinstall nvidia packages" meant the exact words or just rebuilding (with reinstalling) the kmod (generated by akmod) ... but it did not worked .. (including any version of depmod command)

i even tried to give up nvidia drivers (and just use nouveau) but plasma crashes in a loop and does not start at all
horrendous experience especially that i do not know what i will be doing in the future because i cannot stay with the f35 kernel...
