View Full Version : [ubuntu] Ubuntu black screen at login

I just used a LiveCD to install Ubuntu 11.04 x64 on my HP desktop. I'm not sure what you need to troubleshoot. It has the following specs:

HP Pavilion Media Center m8539f PC
AMD Phenom X4 9550 QC Processor
5gb ram, 750 gb hdd
Came with vista home prem, nothing left of that except the old restore partition, which I have left intact. It had Windows XP installed recently, but that's completely erased. GeForce 9300GE Video Card


Anyway, I want the x64 so that I can have access to my RAM, among other things.

After installation with the LiveCD, it will come on, present me with generic/safe/etc boot options, and then when either safe or generic is chosen, it goes to an (active?) cursor for a few seconds before revving the HD, screen going black, and then... nothing. No indication it is even still powered at all except the light on front.


Help :(

I'm very familiar with support/troubleshooting Windows side but I've never had much education, self or any other kind, on Linux systems.

PS I think the black screen occurs around login time, but I had it set to auto login so that I could more easily use it remotely - I usually do a lot of setup on a new computer remotely, ie updates and things, and then remove the capability and restore the login screen later.

I already tried another reinstall once. Same results.

Hi Jeffreylees. You'll see in my signature a link to a "bootinfo script". Please boot to your Ubuntu Live CD, then run this script (all instructions are given at the link), and post the results.txt file back here (either as an attachment, or inside [CODE] tags, which can be activated by clicking the # above the reply box). This will give us an idea of where the problem is in terms of booting, or even whether this is a boot issue (I know some people have run into similar issues due to video card problems).

:)
