Oke i tried, to get something that makes sense. But the system basically goes completely random in failures, sometimes green screen only fixable by enabling proprietary driver and then disabling.
_If_ i get to a gui login it fails between seconds to minutes crashing apps left and right even background daemons failing randomly. After some digging it turns out that my model TU116 may not yet be properly supported. https://nouveau.freedesktop.org/wiki/CodeNames/#nv160familyturing https://nouveau.freedesktop.org/wiki/FeatureMatrix/ I would recommend that the kernel does not attempt to load the nouveau driver for NV140/NV160 at all since they are not supported. it's imo better to have a crappy low res display by default, then completely random behavior. And the low res can be fixed by enabling the proprietary driver. It may also be best to have the ubuntu installer of the next point release automatically install and activate the nvidia proprietary driver for these models so new users don't get a low res display by default. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1876089 Title: Kernel NULL pointer dereference Status in linux package in Ubuntu: Incomplete Bug description: Firefox got stuck opening a page and i was unable to dismiss the application in any way.
