I am using the Devuan distro.
I recently ran Synaptic Package Manager, reloaded, marked all upgrades, and applied the changes. One of the changes was an upgraded kernel version from [whatever]11 to [whatever]12.
Upon reboot, all I had was a terminal screen, no graphics. The Nvidia driver module was not being loaded into the kernel as it boots. When I looked at /var/log/Xorg.0.log I saw an error message:
Code:
[ 53.492] (EE) NVIDIA: Failed to initialize the NVIDIA kernel module. Please see the
[ 53.492] (EE) NVIDIA: system's kernel log for additional error messages and
[ 53.492] (EE) NVIDIA: consult the NVIDIA README for details.
After much internet searching, I realized the kernel headers for the upgraded kernel were not downloaded or installed. Unfortunately, if you look in Synaptic for "kernel-headers" you won't find anything. You have to look for "linux-headers".
I installed all the linux-headers that went with the new kernel upgrade. I then searched Synaptic for everything associated with "nvidia". I reinstalled every nvidia package that was already checked. This time the new nvidia kernel module recompiled and when I rebooted, I got the nice GUI I was expecting.
I'm submitting this new thread to hopefully save the next person the two days of searching it took me and so I can look this up the next time I run Synaptic and get a kernel upgrade.
It sure would be helpful if the kernel headers would automatically upgrade when the kernel upgrades.
