Fedora 11/12 – Nvidia – Maya 7/2009

Recent updates of Fedora 11 and 12 seems to make Nvidia driver not usable in Maya 7 and 2009 in two of our test machine at my client.  I usually use the driver provided by RPM Fusion but this time round, Maya kept reporting Signal 11 error just as it was about to finish starting up.  Using Maya’s Crash Reporting environment variable which kept pointing to libc and TWindow, I thought at first it could be a glibc incompatibility issue.  However rolling back glibc does not seem to solve the problem.  Finally, just out of gut feeling, I removed kmod-nvidia and install the driver (190.53) provided by Nvidia and voila!! Problem solve.

On a different machine, we have i7core with 6GiB of RAM and an NVidia GTX275 with 896MiB of Video RAM. An error along the line of “/dev/nvidia0 input/output error” kept preventing the machine from starting up X window.  After searching on Google for two weeks, a not so obvious answer emerges. I don’t understand the solution but it has something to do with the kernel allocating virtual memory.  The default is 128MiB and for reasons unknown to me, its not enough to get GTX275 started even though it was not a problem previously on Fedora 10.  The solution is to increase the “vmalloc” for the kernel via keying in the value in the kernel parameters in grub.conf.  After I added “vmalloc=256M”, X-Window started up in its full glory!!

legacy sound issue of maya

Apparently Autodesk Maya has not move beyond Open Sound System to ALSA or better yet JACK.  Since I am working with studios using Maya 7.0.1 (yeah I know its ancient, but studios tried to stay legal nowadays so I am bearing with it), a recent upgrade from Fedora 8 to 11 broke Maya sound.  It was not detected a couple of months back since we have yet to reach animation stages which require sound.  Long story short, it hit us and boy was I surprise when I saw from the-Area forum that Maya 2009 faces the same problem!!  Here’s the solution to solve it in Fedora 11:-

  1. Make sure you have installed
    alsa-oss alsa-oss-libs alsa-plugins-oss
  2. create symbolic link pointing
    libaudiofile.so

    to

    libaudiofile.so.0.0.2
  3. In your favorite terminal emulator, start Maya by typing
    aoss maya

Maya crashing on GNOME and KDE but not XFCE4. (Fedora 7 specific)

Been testing Fedora 7 with Maya 7, 8, 8.5 and 2008. Problem is if you are running GNOME or KDE, Maya crashes with signal 11 unless you run “nvidia-settings” first!! Search through the internet and similar experience are reported at Autodesk as well. Quite annoying.

However, it seems that if I run Xfce4 as the desktop environment, I DO NOT need to run “nvidia-settings”. JOY!!

Funny thing is, I tried going even lighter with fluxbox and twm, Maya still require “nvidia-settings” to run first or else it will kill itself with signal 11.

Running KDE with Maya 7, Maya would unexpectedly disappear half way through using it. Not with Xfce4. Xfce4 is running quite reliably with Maya 7, 8.5 and 2008.

The plan now is to roll out F7 + XFCE4 + Maya 7 or 2008. Hate to tell the artists that because they prefer the “better looking” and “advance” KDE. Oh Bother!!

If they could run Blender, all problems solved!!

FC6 installation on Asus P5B and Nvidia 8800.

Download Realtek 8111 driver source

Download Nivida beta driver script

Change BIOS SATA to AHCI

Install FC6 with all the development tools, libraries, X (including server SDK)
– so that kernel source code and compilers are  installed

Remove gdm and yum-updatesd
– remove gdm so you have a text login
– remove yum-updatesd to prevent rpmd errors

Remove all Desktop Environment, Graphical Internet and Multimedia applications

After FC6 is installed on HDD, compile Realtek and Nvidia drivers

reboot

run “system-config-network” to setup eth0 for dhcp and xDSL

yum -y updates
