After installing a base command line install of Ubuntu 10.04, I installed slim and xfce which worked fine for the first 2 or 3 reboots. However, now when I start up, it gets to the slim login screen, I enter in my username and press enter, then I just get a black screen with a couple of random looking characters at the top left of the screen.

Why might this have started to happen?

Does slim have any children? If so, what are they? – Chris Down Feb 8 '12 at 17:03
Might be a bug bugs.launchpad.net/ubuntu/+source/slim/+bug/546292 – lukuluku Feb 8 '12 at 18:26
look at your logs, kill slim then start it by hand. – Aki Feb 8 '12 at 18:40
If I install my system using xserver-xorg-core xserver-xorg-video-vesa, I get the problem described above, however, if I use just use xserver-xorg-core it installs all the video stuff. So I think that means I am installing the wrong video section? How do I find out which video section I need so I don't have to install all of them? – oshirowanen Feb 8 '12 at 19:57

Boot the system into single-user-mode if your computer has that feature, and do the command:

mount -uw /

Then, try deleting the slim files. If this doesn't work, then you will have to reinstall your operating system using single-user-mode. If you don't know what single-user-mode is, just google it.
