Status changed to 'Confirmed' because the bug affects multiple users.

[c4gamerz (arshad-vayani)]

I am getting same issue in ubuntu 14.04. I have installed nvidia 331 driver and when I switch to nvidia, it is throwing following error:

$ sudo prime-switch nvidia
/etc/modprobe.d is not a file
/etc/modprobe.d is not a file
/etc/modprobe.d is not a file
/etc/modprobe.d is not a file
update-alternatives: error: no alternatives for x86_64-linux-gnu_gfxcore_conf

[Max Harris (maxsue)]

I have ann idenical problem to c4gamerz.
It seems to be tied in with Wine and the latest updates to the kernel headers. It all went haywire after installing Wine and the headers on the same day.

[c4gamerz (arshad-vayani)]

I have not installed Wine yet. I have also treid kernel 3.14 and 3.16 but issue still exisits.

[c4gamerz (arshad-vayani)]

I was able to resolve this issue by removing intel grahics installer. Here are the steps I followed:

1) In additional drivers, select nouveau as default driver.

2) Purge nvidia using following command:
sudo apt-get purge nvidia*

3) Completely remove intel graphics installer and files instaleld by it using following guide:

http://theclonker.de/?p=89

replace quantal with trusty.

4) When you purge intel driver i915*, on next reboot an older version might get activated so remove it as well. Simply install synaptic and search "i915" and uninstall if any old version is activated. Restart after that.

5) Enable nvidia driver again in additional drivers. It should work fine!

Now I am using xorg edgers repository and have installed nvidia 340.58 driver. It performs much better than nvidia 331 so I will highly recommend it.

[dino99 (9d9)]

Vivid: that issue does not exist (systemd boot)

[François Jacques (francois-jacques)]

I do see this symptom with Vivid, even after purging everything nvidia related.

[Bontius (bontius)]

It seems to have disappeared in Vivid for me as well:

[François Jacques (francois-jacques)]

@Bontius, you seem to be using xedgers? The bug report was about a stock installation.

[Bontius (bontius)]

True, sorry for the mistake. However I've had this error for half a year now, through two distributions and several [edgers] drivers.

[dino99 (9d9)]

Glancing at the Wily journalctl, its also logged: gpu-manager[797]: /etc/modprobe.d is not a file

[Nathan Adams (nadams)]

I see the '/etc/modprobe.d is not a file' message on Ubuntu 15.04 with my AMD/ATI Radeon HD 7850 video card (so its not isolated to nvidia).

$ sudo lshw -c video | grep driver
       configuration: driver=radeon latency=0

[dino99 (9d9)]

Glancing again at the Wily gpu-manager.log:

that error is gone with Wily installation.

[dino99 (9d9)]

error back into Wily

i've purged the i965-va-driver to see if it makes a diff (i've no intel discrete chip or card on that system)

[Michael Heuberger (michael.heuberger)]

Well, I am on Willy and do not have a Nvidia graphic card but still see the same error:

Looks identical as that fixed one:

so adding that package, might not concern upstart as xenial is using systemd.

This seams to cause a lot of troubles on laptops with hybrid video cards (like nvidia-intel). Since this cannot be taken in for release, I marked it for updates.

[Kyle (d-ayle-t)]

Just installed Ubuntu 15.04 a few weeks ago.... smashing my head against the wall on this one. Any workarounds available? Is there an ETA on a bugfix?

[Peter Antoniac (pan1nx)]

This might be also related to #1410801. Check out also the fixes pushed into #1376966. I will try to test against the latest these days and see if the latest in ubuntu-drivers-common fixed it.

[Marco (hiryu-1)]

As of now I cannot switch to the intel chipset with nvidia drivers (364.19) nstalled. If I run "sudo prime-select intel", and I logout it will fail to login.

[Peter Antoniac (pan1nx)]

It looks like the gpu-manager.log should now be corrected. Anybody else can add more information to keep this bug still open?

[Pam Satterthwaite (pamdemonia)]

So I'm having this problem too. I'm on Wily - pretty vanilla install, although I'm using Gnome once I get that far. I don't have a graphics card at all, just whatever intel put on the cruddy i3 mobo that's in this $300 laptop - so no additional drivers.

What is strange is that I didn't have any problems yesterday, and I am today, and yet I didn't install anything yesterday or do any system upgrading.

Just wanted to say that it's not only in nvidia drivers.

If you need any more details, or logs or debugging help, I would gladly provide.

thanks

I updated to v16 and my pc is now unusable, though i suspect its because i did not disable secure boot.

Do you have nvidia in /etc/modules by chance?

[dino99 (9d9)]

@Florian

/etc/modules is empty (only a few genuine lines commented), so its not the reason pushing that error.

[Florian Fainelli (f-fainelli)]

OK, just wondering because in my case that was it, I had nvidia in /etc/modules and the blacklisted check seemed to fail because of that.

The whole gpu-manager code is pretty unreadable, and quite frankly I don't even think this makes sense to write it in C considering that there is already python code elsewhere, anyway...

[dino99 (9d9)]

Test feedback:

as i use a nvidia-370 driver (true with older ones), nvidia-prime & bbswitch are also installed (does not need them on that pc with a unique nvidia 750 card).

Both nvidia driver & ubuntu-drivers-common install nvidia-prime and then bbswitch.

Purging them both and rebooting : the error is still logged. So there is no relationship on this side.

[RIchard Blakie (rbo8383)]

To those of you who are concerned with this message '/etc/modprobe.d is not a file', note that this message does not reflect an error. It is simply a wrongly placed and mis-worded message in function "is_module_blacklisted" in gpu-manager.c However, this does not address the situation of incorrectly loaded/unloaded modules for video card changes, which I am scanning the code for. (I am not a developer...)

The line containing this message should be deleted, AND the following line added immediately after the ' if (dry_run) {' line in the same function :

        fprintf(stderr, "In dry_run mode(test), therefore we are not using %s directory \n", modprobe_d_path);

The resulting function code should be as follows :

static bool is_module_blacklisted(const char* module) {
    _cleanup_free_ char *match = NULL;
    char command[100];

    /* It will be a file if it's a test */
    if (dry_run) {

        fprintf(stderr, "In dry_run mode(test), therefore we are not using %s directory \n", modprobe_d_path);

        snprintf(command, sizeof(command),
                 "grep -G \"blacklist.*%s[[:space:]]*$\" %s",
                 module, modprobe_d_path);

        if (exists_not_empty(modprobe_d_path))
            match = get_output(command, NULL, NULL);
    }
    else {
# fprintf(stderr, "%s is not a file\n", modprobe_d_path);
        snprintf(command, sizeof(command),
                 "grep -G \"^blacklist.*%s[[:space:]]*$\" %s/*.conf",
                 module, modprobe_d_path);

        match = get_output(command, NULL, NULL);
    }

    if (!match)
        return false;
    return true;
}

[Manfred Hampl (m-hampl)]

Doesn't the first grep command in is_module_blacklisted need adding a ^ identical to the second one -

"grep -G \"blacklist.*%
vs.
"grep -G \"^blacklist.*%

to avoid matching commented-out entries (like "#backlist noveau" etc.)?

I'm on 16.04.1 with nvidia 378 (from ppa) and am getting these errors too. So "/etc/modprobe.d is not a file" is safe to ignore. What about "update-alternatives: error: no alternatives for x86_64-linux-gnu_gfxcore_conf" ?

I have elementary OS 0.4 Loki (based on Ubuntu 16.04.2 LTS) on a Macbook Pro (Retina).

Yesterday i installed the HWE Kernel and Xorg.

apt install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

Today i rebootet the system since the resolution of the display was strange after suspend. But then i had only tty, no desktop.

I rebootet again and everything was normal again.

But the reported problem is still the case:

Not sure if it is related since people have it also with stock xenial.

[Nazar Mokrynskyi (nazar-pc)]

@davidak, you might need to build Nvidia module with dkms manually (it fails building automatically for me too more often than not).
You can do this like following:
sudo dkms install -k 4.10.0-11-generic -m nvidia-378/378.13

Just replace kernel version and Nvidia driver version with what you have currently.

[Ken Sharp (kennybobs)]

I installed DKMS and it went away.

It seems to have to do with the Intel side of things. Something not getting done right because of it being 6th or 7th generation. It all pretty much goes to hell in a handbasket when you turn on Intel mode to try to save power. A switch from the command line (Once you go into recovery and exit...) puts it right. Seriously guys. Two plus years on this bug. It's telling that either you're incompetent, or you've got major, major design flaws in the system as a whole and in EITHER case you need to rework things.
