NVIDIA – 4.20-rc1 Fix? – More Work Needed..

I created a combo runtime patch for NVIDIA 410.73 on Kernel 4.20-rc1, by combining the changes identified in my previous article ( see http://rglinuxtech.com/?p=2426 ) with the pm patch (see http://rglinuxtech.com/?p=2421 ).

The result ran – eventually – after blanking/refreshing the display, with garbage characters at top/bottom, so all was obviously not OK..

The (KDE/Plasma) screen seemed to be OK after that, but this is obviously not an ideal solution!

NVIDIA – 4.20-rc1 Fix? – More Work Needed.. — 2 Comments

  1. No surprise (as there’s no kernel changes mentioned in the changelog) but 410.78 has the same issues with 4.20-rc as 410.73.
