Title: Lubuntu greeter screen goes black, can't log in
Post by: Spyro543 on December 04, 2014, 08:05:30 pm

So I have this old Dell Dimension 4700 that I want to use as a dedicated emulation box. For some reason though, parts of the Lubuntu greeter will appear (just the wallpaper and the mouse) for a few seconds, then turn into a black screen with a blinking cursor. When I try to log in with one of the other TTYs, it will show the "Welcome to Ubuntu" text for a split second, then go right back to the login prompt. I'm using Lubuntu 13.10. Any thoughts? It worked just fine before today.



Also, another weird thing. I tried to reinstall Lubuntu, but the installer kernel panics (and shows no useful information) as soon as I hit "Install" or "Try Lubuntu without installing".

This sounds similar to a problem I once had on Ubuntu on this laptop. I don't remember how it should be fixed, but it got fixed quickly with the help of those guys on the official #ubuntu irc channel (http://irc.lc/freenode/ubuntu). They'll probablly be able to help you as well.

I fixed the problem. It turns out that some of the RAM in the computer was bad. I took out the bad RAM and everything works fine now.

Glad you fixed it.

I was going to mention that I'd been having trouble with light-locker turning the screen black after logging in (which seems to be a pretty common bug in Xubuntu (https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1303736) right now) but I guess it's a different issue.
