Check your /var/log/Xorg.0.log file to see if the Nvidia drivers are<br>
actually being used. If not, try purging the Nvidia packages<br>
completely and reinstalling them. It is best to reboot after the<br>
purge, but you need to have ssh access from another PC to then do the<br>
reinstall as you are unlikely to get a GUI screen.<br>
<br>
If the Nvidia drivers are actually being used, the log file should<br>
show a line like this:<br>
<br>
[ 35.266] (--) NVIDIA(GPU-0): DELL 2707WFP (DFP-1): connected<br>
<br>
when your monitor connects to the GPU. And there will be heaps of<br>
other lines with "NVIDIA" in all capitals telling you what the Nvidia<br>
drivers are doing.<br><br></blockquote><div><br></div><div>Thanks, I think that Kubuntu does something weird on installation. I know that on my system if I select install 3rd party drivers on install the Installation program crashes. So I installed it with that option unchecked. That must be why they don't allow you to change your mind later and gray everything out. So I did: "sudo ubuntu-drivers autoinstall" and then rebooted. </div><div><br></div><div>Now all the normal options are available in mythfrontend and I can select NVDEC and it works correctly with no jerkiness. </div><div><br></div><div>Thanks,</div><div><br></div><div>JIm A</div><div><br></div></div></div>
