Video playback problems on 15.1 core on old machine

Hi all,

I have been installing Zorin on anything I can get my hands on. One of the anythings goes like this:

Old HP Pentium4 dual core 2.5GHz with 6GB RAM, Small 80GB disk (by choice) with on board graphics card supporting VGA and DVI-D. I however wanted HDMI output... so...
Replaced the HP PSU from 300 Watt to an EZCool 400Watt and put a generic card with DVI-D, VGA and HDMI outputs. I has a sticker with GT210 on it (or G210).So I assume it is a generic low end old nVidia card (or maybe I assume wrong).

When Running VLC everything runs fine.
When running Kodi and pausing for a while the screenlock kicks in and upon unlock and pressing play video playback stays frozen but audio (and playback time) run normally. I have to stop the playback and resume from wherever I stopped.
When running youtube in normal or theater node playback is smooth. When I enter full screen video stutters but audio is normal.

What I though of doing is:

Back up everything with clonezilla ( hate to have to reinstall from scratch)
Try nouveau drivers
Worst case restore the whole disk via clonezilla

There is no data there, it is just a playback rig (and is sooo quiet and cool, excellent craftsmanship) hence the small HDD.

Insights? Ideas? Suggestions?

Hi, I had major issues with Zorin 15 on my rig which had a 2Gb GT-620 - the minimum spec card that should run fine is a GT-730 (per team Zorin). I upgraded to a Zotac nVidia 1030 2Gb as I was getting all sorts of different screen resolution errors. I would also suggest you put Zorin Lite on it instead - even 12.4 Lite.

Ok.... I guess I will backup the setup and try nouveau (because I am a mazochist when it comes to reviving old rigs) then 15.1 lite 64 bit... and if that does not work I will go for 12.4 although I am not excited about the option. Worst case I will live with the annoying inconveniences. Zorin 15.1 Core is sooooo smooth on that rig ...

Ok just a quick update... I entered the additional drivers tab in software updates and I could either use nouveau or Nvidia. I chise nvidia (I was feeling lucky) and now everything works and all problems with video playback solved and all that on Zorin Core 15.1

Good to know!
