Drivers in the 340 series are still being updated by NVIDIA (the 340.108 <br>
driver (December 2019) patched the driver to fix a kernel change in <br>
5.x??) here:<br>

<br>
Latest updates on July 9, 2020.<br>
<br>
Which includes really really good instructions on installation on Fedora <br>
30 through 32.<br>
<br>
The drivers are available directly from:<br>

And search for GeForce 9 on Linux64.<br>

I bought a new SSD, scrounged 4GB of RAM and have ended up running Fedora 32 and MythTV v32 (Master), which has a nice symmetry but is not what I was aiming for!</div><div><br></div><div>To start with I installed lubuntu 20.04 with Myth31 and then lubuntu 18.04 with Myth 29, because I was having intermittent playback problems and had read about big changes in the playback code for Myth 30 and 31 (certainly the playback profile settings have changed a lot).
