RHEL/CentOS 7.6, Maya 2018, and NVIDIA

Hello,

Last night I upgraded my personal workstation to CentOS 7.6 (I use it as my testbed as well for desktop related things). Since then, Maya's Viewport 2.0 has
been impossible to activate. It seems like Maya isn't properly finding the NVIDIA driver, which may or may not be due to the switch to GLVND in 7.6. All other applications (Mari, Substance, Nuke, etc) seem to be finding things just fine. Has anyone else run into this issue or are you all playing it smart and not updating things?

Currently running 2018.2, also tried 2018.5 and no change. Driver 410.78 from elrepo.

Cheers,
Mike

Alright, results:

Maya is not compatible with GLVND enabled drivers. If you are using the ElRepo NVIDIA driver, updating to 7.6 will nulify Maya's VP2 and color management. You will need to install the driver by hand and explicitly specify the GLVND disabling flags. This isn't ideal as it will overwrite system libraries, and any updates to the glvnd-* libraries could potentially overwrite the driver.

Cheers,
Mike

Well, this was interesting. After a few days of further debugging with containers (and about to start testing 16 self-built libglvnd packages) everything started magically working today. The reason: systemd.

In the past 24 hours RH/CentOS released updates for the following packages:

systemd, systemd-libs, systemd-python, systemd-sysv, and libgudev1 which had the following in the changelog (the only two commits since RHEL 7.6's release):

* Mon Jan 07 2019 Lukas Nykryn <lnykryn@redhat.com> - 219-62.2
- journald: do not store the iovec entry for process commandline on stack (#1657788)
- journald: set a limit on the number of fields (1k) (#1657792)
- journal-remote: set a limit on the number of fields in a message (#1657792)

* Mon Nov 26 2018 Lukas Nykryn <lnykryn@redhat.com> - 219-62.1
- dhcp6: make sure we have enough space for the DHCP6 option header (CVE-2018-15688)

Turns out something there was indirectly breaking libglvnd from functioning properly.

Cheers,
Mike
