Hi,

I have a five year old PC with just about every aspect of it phased out, thus I'm forced to use an old version of Linux, that is CentOS 6.6. Which is fine, but I want to use the latest builds of certain software such as Blender and Krita. I haven't been able to find any method of doing that without destroying my OS and having to do another fresh install, and my PC doesn't have the power to run virtual environments. I've just discovered this technique of using "Linux Containers," via docker, and I wanted to give it a try to run graphics applications through this hybrid portable-sandboxed system. However, I can't find any examples or tutorials on achieving that. Everything seems to be related to just running commands from the terminal. Is it even possible right now for containers to run any kind of program with a GUI?

a small step would be to upgrade to CentOS 7.0 - but if you want current sw its probably worth the effort of installing a distro that stays more up to date

ask about containers on docker.com but somehow I don't think that's gonna be your solution (and i have know knowledge of such) if you need to run an older OS because of hw adding any kind of layer desn't seem like a good idea

you should also post you specs they may not be as bad as you imply (or not)

you might consider a minimal distro and de for older hw, lots of discussions on distrowatch.com

Which specs affect framerate performance?

framerate regards Blender? you should ask on their forum as it's not KDE sw

Sorry I didn't mean to focus on specific software. I'm still unsure which specs to list, if I should give just the names/types or just generic titles with what they're capable of...

model of cpu, graphics card if not integrated, and how much ram - these are what are going to affect your performance depending on what the app uses (I don't think Krita uses the gpu).

but you need to ask on the specific sw forums to see if your hw is sufficient based on what you're trying to do and what if anything you can do to improve performance at at a low or zero cost

the graphics can be determined, if compositing is enabled, by running in Konsole

Code: Select all

 glxinfo | grep OpenGL

Sorry to butt in but my laptop is 8 years old and running fine on the latest Debian Testing with KDE and all its bells and whistles.

What I am getting at is why you don't use up-to-date software? You are bound to have a dual core processor and upgrading RAM is pretty cheap. Another bottleneck could be an old harddrive. Again, a five year old motherboard will have SATA connections. Coming to think of it, my desktop is six years old but runs like the proverbial **** off a shovel.

Specs of interest would be RAM, processor, motherboard (if available).
