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

Adventures With Linux ™ Posted on by

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.. ……………………… [ 121.826292] [drm] … Continue reading →
