Yes, I rebuild the system from sources at least once a day, but do only reboot every few days, especially if there has been any change that might cause incompatibilities between kernel and user land. And I always rebuild all KLDs together with the kernel, including all the driver module ports relevant for X11. > *There can be some (sometime very wide) timeframe between LinuxKPI > update and corresponding linux-*-kmod catches up with it. X11 was working just fine on a system built and rebooted a few days ago. > Looking into cgit.freebsd.org, at least drm-current-kmod is updated 36 > hours ago. Not sure it's related or not, though. I had missed that update - and YES you are right. I'm using the devel version and after reverting the update to drm_v5.5.19_7 the driver does attach again. Thanks for the hint! > *I always prefer nvidia dGPU because of these dangerous span. > So I've forced to choose ThinkPad P series (without "s") which > usually can disable CPU-integrated Intel GPU and run nvidia GPU > alone though BIOS setting. I had issues with Nvidia cards (and the closed source driver modules and libraries) before and for that reason bought a passively cooled Radeon card for this development workstation.
