Nvidia probem?

Can someone confirm if the current nvidia package is working properly? It 
seems that on my system the nvidia.ko and nvidia-uvm.ko modules are not 
beeing generated so dracut fails when trying to package them. Downgrading 
to the previous version has the same effect, so I assume the problem is not 
with the nvidia package itself. My current guess is that there is some 
incompatibility with the linux-headers package... or I managed to put my 
system in some inconsistent state.

I never managed to get my GT635M working but it might be a different issue. 
I am using a Thinkpad E530 with Optimus and don't have a setting in BIOS to 
disable the integrated graphics. From what I tried so far I always end up 
with 'failed to load DRM permission denied'

This is just an artifact of an incomplete /usr/sbin merge switch.

Please run the following commands to have a working system and with 
/usr/sbin fully merged:

- xbps-install -Suv
- if /usr/sbin is a directory and not a symlink, remove all regular files 
on it, keep the symlinks.
  - Reboot
  - runit-void will then make /usr/sbin a symlink to /usr/bin, and the old 
/usr/sbin directory will be renamed to /usr/sbin.old
- Reconfigure nvidia `xbps-reconfigure -f nvidia{,-dkms}`
- Your system should be fully functional again.

Cheers

I can confirm that the /usr/sbin transition was not complete on my system, 
but fixing that did not fix the original problem. Executing 
"xbps-reconfigure -f nvidia" still gets me:

Regenerating initramfs, please wait...
/usr/lib/dracut/modules.d/90kernel-modules/module-setup.sh: line 13: /lib/
modules/4.0.4_1//kernel/drivers/video/nvidia.ko: No such file or directory
/usr/lib/dracut/modules.d/90kernel-modules/module-setup.sh: line 13: /lib/
modules/4.0.4_1//kernel/drivers/video/nvidia-uvm.ko: No such file or 
directory

So I went to /usr/src/nvidia-346.72 and tried a "make":

NVIDIA: calling KBUILD...
make[1]: Entering directory '/usr/src/kernel-headers-4.0.4_1'
make -f ./Makefile silentoldconfig
make -f ./scripts/Makefile.build obj=scripts/basic
rm -f .tmp_quiet_recordmcount
make -f ./scripts/Makefile.build obj=scripts/kconfig silentoldconfig
mkdir -p include/config include/generated
scripts/kconfig/conf --silentoldconfig Kconfig
make -f ./scripts/Makefile.build obj=arch/x86/syscalls all
scripts/Makefile.build:44: arch/x86/syscalls/Makefile: No such file or 
directory
make[2]: *** No rule to make target 'arch/x86/syscalls/Makefile'.  Stop.

make[1]: *** [archheaders] Error 2
make[1]: Leaving directory '/usr/src/kernel-headers-4.0.4_1'
NVIDIA: left KBUILD.
nvidia.ko failed to build!
nvidia-modules-common.mk:248: recipe for target 'module' failed
make: *** [module] Error 1

As is to be expected, the same happens in /usr/src/kernel-headers-4.0.4_1 
directly:

scripts/Makefile.build:44: arch/x86/syscalls/Makefile: No such file or 
directory
make[1]: *** No rule to make target 'arch/x86/syscalls/Makefile'.  Stop.
arch/x86/Makefile:181: recipe for target 'archheaders' failed
make: *** [archheaders] Error 2

That "arch/x86/syscalls" directory is not part of the linux4.0-headers 
package. Do I need to generate it somehow? Or am I missing something else 
entirely?

This Makefile you are mentioning about does not seem to exist.

What I think happened is that the first upgrade executed dkms and this 
failed to build the nvidia kmods, but dkms thinks it was built and 
installed correctly.

Do this:

- dkms build -m nvidia -v 346.72 -k $(uname -r)
- dkms install -m nvidia -v 346.72 -k $(uname -r)
- xbps-reconfigure -f nvidia

Before running xbps-reconfigure, make sure the kmods are built and 
installed correctly.

The proprietary Nvidia module was working fine .
/usr/sbin is a symlink.
the module builds OK but depmod fails with an exit status of 127 after this

Did you compile/install the module as root? What exactly is the error 
message? My guess is that the 127 is probably coming from make, not from 
depmod.

Do you also get an error when you run something lilke "depmod -nv" manually?

2.6meg of text?

depmod -nv | grep nvidia:
kernel/drivers/net/ethernet/nvidia/forcedeth.ko.gz:
alias mbp_nvidia_bl apple_bl

no error message in the depmod output. I'll try after cleaning 
/usr/src/nvidia-346.72 & dkms build etc.

I have been having the same problem for a couple of days, but I stayed 
determined  and I just figured out how to solve it.

Check your /sbin directory and make sure the void-installer binary is 
removed. Reboot and reconfigure nvidia. Worked for me, I hope it works for 
you.

Fixed! Thanks to everyone for their help. Especially JD Robinson's lxdm 
hint.

The problem was entirely mine. I missed the one regular file (i.e 
non-symlink) in /usr/sbin with the virtual terminal switching every 4 
seconds so I didn't delete it. I started from scratch again, stopped lxdm 
and then I could see it. After rebooting and
dkms remove -m nvidia -v 346.72 -k $(uname -r)
dkms build -m nvidia -v 346.72 -k $(uname -r)
dkms install -m nvidia -v 346.72 -k $(uname -r)
modprobe -v nvidia
sv start lxdm
and I was back to a graphical desktop.

This also seems to have worked for me.

I had a difficult time logging in because lxdm was respawning.

sv stop lxdm

For anyone having a similar issue.

Yes, that did it. All working correctly now. Thank you very much for your 
help!
