Hello, linux newbie.

"Cinnamon running in software rendering mode" is a fall-back mode. In normal mode Cinnamon depends on and uses 3D hardware acceleration of your graphics card. Whenever it cannot detect any support for 3D hardware acceleration, it will fall back into software rendering mode. In this mode all the work has to be done by the normal CPUs instead of by the GPU. This is why in software rendering mode everything will be extremely slow and laggy.

Your inxi report displays this in the "graphics" section:

Code: Select all

Display Server: X.Org 1.17.1 drivers: (unloaded: fbdev,vesa)
The relevant thing is not what you see in this line but what is not present. What is missing is the name of the loaded graphics driver. This means it has not been loaded.
If everything were right the line above should read:

Code: Select all

Display Server: X.Org 1.17.1 drivers: intel (unloaded: fbdev,vesa)
I admit that I am a bit clueless as to why the system fails to load the Intel graphics card driver. But this will be the root cause that needs fixing.
It might be related to the specific combination of Intel components on your mobo and kernel 3.19.0 e.g. Not sure.

Hope someone else who uses Mint 17.3 Cinnamon on Intel will know better and chime in soon ...

Cheers,
Karl

It's probably because of the 2GB of RAM space...

I have always been of the opinion, 64 bit is NOT just for >3Gb RAM :D

64 bit hardware was meant for a 64 bit OS, regardless of the amount of memory.

I can't really say that the issue is "solved " per-say. I completely removed Mint 32-bit and replaced it with Mint Mate. I gotta say it runs phenomenally. No hiccups, no nada. Don250r It's a small machine and was curious bout mint. Thank y'all
