Apple OSX 10.2 on Linux using the PowerPC CPU emulator Pear

I was able to get OS X 10.2 (PowerPC) running in Pear (PowerPC emulator for Windows and Linux) on Kubuntu 16.10 🙂

I need to set up the tun0 interface in order to get networking (internet) working.

HowTo: Plex Home Theatre (Plex client) for Ubuntu Linux!

Installing Plex Home Theater in Ubuntu (or related distributions) is quite easy but it isn’t documented all that well.

sudo add-apt-repository ppa:plexapp/plexht
sudo add-apt-repository ppa:jon-severinsson/ffmpeg 
sudo add-apt-repository ppa:pulse-eight/libcec
sudo apt-get update
sudo apt-get install plexhometheater

You will find it in your desktop menu or you can call it directly:

/opt/plexhometheater/bin/plexhometheater

Getting three monitors to work with Kubuntu (Ubuntu with KDE) on a Dell Optiplex GX520 – NVidia GeForce4 MX 4000 low profile video card and the onboard Intel 82945G/GZ video card

At work we have three generic LCD monitors mounted on a pole to view monitoring metrics for our Oracle & Sybase database servers. On a previous machine that was cannibalized for another task, we ran Microsoft Windows XP to drive the three monitors.

Last week we were given a hand me down desktop, a Dell Optiplex GX520 with integrated Intel 82945G/GZ video on the motherboard. When we added the NVidia GeForce4 MX 4000 low profile video card, Windows XP for whatever reason was unable to use both video cards. I proposed Kubuntu 9.04 Linux as an alternative. As it was only myself that I had to convince to make the attempt, I was hard pressed to say no 😉

The Intel 82945G/GZ video card will be the primary card and must be attached to “Screen 0” in the ServerLayout section.

The NVidia video card has two connectors:

  1. A standard VGA port driven by a GeForce4 MX 4000 GPU < - Primary nvidia port
  2. A super-video port driven by a Quadro NVS 110M

After the base install of the operating system, XWindows was only able to see the Intel video card. After much tinkering with the /etc/xorg.conf file, I was able to get all three LCD monitors to work with Xinerama. There are a number of gotchas that you might run into:

  • If the integrated Intel video card is set to Auto in the BIOS, the card will be completely disabled. You need to disable Auto
  • You need to know which Nvidia Device entry drives the VGA connector. It must be initialized prior to the S-Video port.
  • Disable NVidia’s TwinView and metamodes option lines in the Screen Section.
  • Use sudo lspci to identify the pci bus ids. You will need to put them in the Device Sections.
  • The integrated Intel video card must use the vesa video driver as the intel video driver will stacktrace when used with xinerama.
