<div dir="ltr"><div>I'm just going to toss a couple of ideas out there, as I used to have this same issue repeatedly with Ubuntu. Based on my own experience, I have to ask if you're using an Nvidia video card? The drivers for that are usually the culprit.</div><div><br></div><div>Have a look here: <a href="https://discuss.kde.org/t/black-screen-with-cursor-after-updating-kde-neon-to-plasma-6/11193">https://discuss.kde.org/t/black-screen-with-cursor-after-updating-kde-neon-to-plasma-6/11193</a></div><div><br></div><div>Also, if you can't login via Ctrl-F4 with your username, can you login as root? (some distros, like Ubuntu, don't allow root login, but maybe your distro will let you in). Also, sorry for asking, but are you saying that you might not have the right password for your user?<br></div><div><br></div><div>If you have no hope of login via terminal, then you may have to do the Secret SysAdmin Trick to reset the root or user password, as the case may be. There are different ways to do that, but one that might work for you can be found at <a href="https://linuxconfig.org/recover-reset-forgotten-linux-root-password">https://linuxconfig.org/recover-reset-forgotten-linux-root-password</a></div><div><br></div><div>Gain root login via grub, then reset either root or your user password as necessary.</div><div><br></div><div>Ubuntu used to do this to me all the time. As I mentioned, the culprit is the Nvidia drivers. I solved that problem by buying an not-Nvidia GPU. And I switched to Debian instead of Ubuntu for various reasons.</div><div><br></div><div><br></div><div><br></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sat, 28 Dec 2024 at 12:54, Darren Pond <<a href="mailto:pilotpond@gmail.com">pilotpond@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Good day.<div dir="auto"> Can anyone point me to a person that can help me recover from a bad software upgrade on KDE plasma 6.4 OS on a desktop cpu? <div dir="auto"><br></div><div dir="auto">I now have a black screen with a working mouse cursor and ctrl F4 does not accept my login/pw.</div><div dir="auto"><br></div><div dir="auto">I live in town of Simcoe.
