How do I ascertain whether this device has a "dedicated graphic accelerator" and "64 MB of on-board graphic memory"?

Slicer requires a minimum of 2 GB of RAM and a dedicated graphic accelerator with 64 MB of
on-board graphic memory.

I don't know whether these things accelerate graphics, are dedicated, or are graphic memory. I'm not even sure if a controller is the same thing as a graphics card.

My conclusion so far is that a controller is part of the CPU, not a graphics card, and that I do not have a 'dedicated' graphic accelerator, that this is referring to a graphics card with its own processor separate from the CPU, and likewise that this graphics card should have 64 MB of its own memory. Hence my tentative conclusion is that this computer cannot run 3D Slicer as designed, and my tentative answer to this question is "use sudo lshw and check the 'display' section", but I hope to hear from you to learn more, if I am mistaken.

  • "a dedicated graphic accelerator with 64 MB of on-board graphic memory" is fairly useless as a guide to whether a particular machine will run the software. I'd recommend just trying it and seeing if it works or not. – Chai T. Rex Feb 5 '18 at 5:05
  • I have encountered errors, and it froze my computer once, but I'm not sure if I was simply misusing counterintuitive software. I had hoped I was 'being smart' by determining here that a CPU graphics controller -- ie integrated graphics on a laptop, rather than a graphics card in a desktop computer -- was insufficient to run this software. On one hand the software appears to work, but on the other hand I've gotten IO error, loading data is slow, and my computer froze trying to load a CT, so maybe it doesn't work. – DBinJP Feb 5 '18 at 5:48
  • If you get IO errors, that might be the disk failing. Try opening the Disks program, opening the hamburger menu (☰) in the upper right corner, and running an extended SMART test. – Chai T. Rex Feb 5 '18 at 6:11
  • Power-On Hours and Power Cycle Count are type 'Old-Age', and the other four (used-reserved-blocks-chip, used-reserved-blocks-total, unused-reserved-blocks, runtime-bad-block-total) are type 'Pre-Fail', but my understanding was that 3D Slicer was giving an IO Error because RTPLAN DICOM files are not supported (i.e. weren't in the previous version, and so aren't in this latest version 4.8, either). – DBinJP Feb 5 '18 at 10:18
