[Solved] Crash in gdm with nvidia-349.16-1 driver

After I installed the latest nvidia drivers yesterday, gdm started crashing.

1. For a brief second, I see a mostly black screen, with some weird artifacts (static, lines, that sort of thing).
2. I see the gray "oh, no" screen of gdm with a log out button.
3. Pressing the log out button restarts gdm with the exact same outcome

This is on an MacBook Pro 11,3.

I know of two other people with the same problem.

Installing nvidia-340xx got rid of the crash for me.

Are there any logs I can look at to help pinpoint the actual problem?

Have a look at this thread https://bbs.archlinux.org/viewtopic.php?id=196499 maybe it's related

Yes, it's related to the bug in the thread mentioned by MK13. After the gdm crash I got coredump and libpthread error messages, too.

Installing intel-ucode and adding the initrd= option to the bootloader config as desribed in the wiki (https://wiki.archlinux.org/index.php/Microcode) solved the issue for me.

Thanks for the tip, but It didn't work for me.

There appears to be no microcode updates for my cpu, all I get is:

~ dmesg | grep microcode
[    0.461189] microcode: CPU0 sig=0x40661, pf=0x20, revision=0xf
[    0.461199] microcode: CPU1 sig=0x40661, pf=0x20, revision=0xf
[    0.461204] microcode: CPU2 sig=0x40661, pf=0x20, revision=0xf
[    0.461209] microcode: CPU3 sig=0x40661, pf=0x20, revision=0xf
[    0.461215] microcode: CPU4 sig=0x40661, pf=0x20, revision=0xf

[    0.461225] microcode: CPU6 sig=0x40661, pf=0x20, revision=0xf

[    0.461262] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

And the same issue as before. Artifacts at the top of the screen and then the crash screen.

What CPU? Did you actually check it against the microcode image?

Re: [Solved] Crash in gdm with nvidia-349.16-1 driver

iucode won't build for, me, I just checked the revision number (/sys/devices/system/cpu/cpu0/microcode/version) before and after I installed intel-ucode and updated grub.

My cpu is:
Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz

Which is haswell based. If you don't have a BIOS update installed that includes a new-ish microcode, you definitely need the intel-ucode updates.

Edit: And your microcode is not up to date.

% bsdtar -Oxf intel-ucode.img | iucode_tool -tb -ls0x40661 -
selected microcodes:
001: sig 0x00040661, pf mask 0x32, 2014-07-03, rev 0x0012, size 23552

Re: [Solved] Crash in gdm with nvidia-349.16-1 driver

Thanks, it works now

I misunderstood the part about iucode-tool, was in a bit of hurry when I did this.

Here's what I did if anyone else has the same problem:

1. Install intel-ucode and iucode-tool
2. modprobe cpuid
3. bsdtar -Oxf /boot/intel-ucode.img | iucode_tool -tb -lS -
4. grub-mkconfig -o /boot/grub/grub.cfg
5. reboot
