Which kernel? Was it recently upgraded? 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

Hi Edward, The only thing I can add to the discussion is that about a decade ago I used to see this symptom (a kind of moving "tearing" of the screen to the point of unreadability) on lots of laptops. I'd need to reboot several times to get it to work properly and it was a real pain in the ass. As time went on, I stopped seeing the symptom. I think probably Linux drivers caught up to my laptop's hardware. As experiments, I'd try the following to see if they alter the symptom: * Temporarily try it booting directly to X and see if things get better * If it uses "plymouth", get rid of plymouth and see if things change * Try to see if the tearing occurs before or after the running of udev/eudev/vdev. If after, try changing some video related udev/eudev/vdev config parameters. * Boot a System Rescue CD DVD or thumbdrive, and see if the symptom still occurs. If not, you can slowly exploit the differences between System Rescue CD and your Devuan installation until you pinpoint the root cause. * Boot a live or install disk of the latest unstable Devuan and note any change in symptom. * Create a tiny partition on your computer and install a tiny Void Linux OS, then update with xbps-install -Su so you have an up to date rolling release system with pretty much the latest kernel and drivers. * Don't worry too much about the "joke" aspect of the thing. I've seen this before, on non-HP hardware.

Over the past 5 years or so, it seems like it only works about half the time. And I mean it goes months without being available for installation. I do still use Thunderbird for my mail, but a few months ago I installed claws mail on my laptop just so I could send an encrypted email. It works fine there. I might eventually switch over to using claws full-time. fsmithred ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
[DNG] Linux kernel boot causing screen to become unreadable.
Dear All, Lately, on an HP Probook 4540s, while booting Devuan Boewulf the screen becomes completely unreabled with unsynchronized lines of pixels. I will not be surprised if this is some sick joke by HP, to force their customers to buy new, but I do not know if this is the case with what I am experiencing. The hopelessly corrupted display persists even when startx is invoked, but the screen pixels indicate X fails to load. The 'joke' vanishes if I try to reboot the machine without switching off power and startx works as if nothing of the sort exists. I am asking but bearing in mind, the HP is not very Linux friendly and that this issue might be some creative joke on their part. Afterall, Aitor was right, that HP are not very Linux friendly! Those who have a solution please reply. I tried the 'nomodeset' kernel parameter but it made the issue even worse. Thanks in advance. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

[DNG] TB and Enigmail
Hi all, Yes, I use TB. Please excuse me for living. I am wondering how other TB and GPG users are dealing with: https://wiki.mozilla.org/Thunderbird:OpenPGP:Migration-From-Enigmail From what I understand, I now have to maintain two copies of my key rings: the regular one and the one *inside* TB. Somehow this smells like maybe someone didn't read Superiority or they just hate their users and want them to go away. Has any of you TB users (assuming there are any here} done this migration? How is the new shiny? Is it fine? Shall I forget about TB? Any suggestions of what could replace it? I see SOGo are working on the new format: https://www.mail-archive.com/users@sogo.nu/msg30023.html Though, I want to consider alternatives as, I somehow don't trust Mozilla ever since they became SJ warring virtue signalers. Sure, it was a while ago. I find it hard to move on, which, like many of you, is why I don't like it when software changes.
