when upgrading to Linux 5.2, NVIDIA driver is not loading

[hesifwood]

System

Void Linux running with NVIDIA GeForce GT 1030 gpu on proprietary drivers. I installed the nvidia package when setting up.

• xuname:
  Void 5.2.13_1 x86_64 GenuineIntel uptodate rFFFF
• package:
  linux5.2-5.2.13_1, nvidia-430.14_2

Expected behavior

Being able to get proper resolution like before on 4.19 and open nvidia-settings without errors after upgrading to Linux 5.2

Actual behavior

When GRUB booted to 5.2, the resolution was not like before and running nvidia-settings showed me this error:

$ nvidia-settings

ERROR: NVIDIA driver is not loaded


ERROR: Unable to load info from any available system

lxrandr was showing resolution 1024x768 under 5.2 and 1366x768 under 4.19.

Steps to reproduce the behavior

• I upgraded recently with sudo xbps-install -Syu
• I had standard Void install, so it automatically installed Linux 5.2 (probably due to this change)
• When I did a reboot it booted into 5.2 and the screen resolution was not ok and nvidia-settings was showing error

I posted on reddit and got the solution:

sudo sh -c "xbps-install -f nvidia-dkms ; depmod -a"

Afterwards a reboot made it work fine again. Resolution came back to normal and nvidia-settings was launching without errors. So should this be automatically running somehow? Or if not possible, maybe showing a post-install message would be a good idea?

Can second the issue.

During the update itself the dkms module fails to build, but this is known, see: #12959 (comment)

I would also recommend a post-install message for this.

EDIT: This issue applies to all nvidia*-dkms packages, of course.

This should be resolved by 9861370.

xbps-reconfigure -f nvidia-dkms triggers the xbps dkms hook /usr/libexec/xbps-triggers/dkms,
which already exported IGNORE_CC_MISMATCH=1, while the /etc/kernel.d hook which triggers dkms rebuilds on kernel updates/installs didn't export it.

So xbps-install -Su would rebuild the module using the kernel hook and fails, while xbps-reconfigure -f nvidia-dkms uses the other trigger which already makes the dkms script ignore the mismatch.

Thanks for the quick reply/fix!
