Which video drivers are your using? What is your display configuration? My only suggestion is to ask if you can reboot on an older kernel and achieve a working solution. Also check if your video hardware is supported by the video drivers your system is attempting to load. (Hint check /var/log/dmesg.'n' and /var/log.Xorg.1.log). IME, sometime after generally upgrading to Beowulf, the default(startup) video drivers went askew. I first noticed this when I attempted installations of Devuan beowulf onto 'clean' hardware. With one system I had to go back to Jessie to be able to do a basic server install. Since my problem was on a AMD FX motherboard with AMD video card under the "Radeon" driver, the problem may not be HP related, but rather something to do with code for AMD. In other, probably useless information, you can now upgrade kernel up to 5.8 through backports (sudo apt search linux-image-5), but I doublt if that will fix your problem. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
