Ubuntu 9.04 boots to blackscreen with mouse pointer
I'm having trouble getting Ubuntu 9 to boot. Everything looks fine until the Ubuntu logo and progress line blank out, I think to go the GUI. All I get is a black screen with the mouse pointer in the middle. The keyboard and mouse are dead at that point. The only out is to power off and try again. I finally got fully booted this afternoon and everything seems to work fine, but I know if I shut down the problem sequence will start all over again. Can you help me diagnose what the problem is? I know nothing about linux, but I'm sure I can follow instructions to input command line commands.
Dell Optiplex with 1.7 ghz P-4 256 MB memory 20 GB drive, dual boot with Win XP and Ubuntu 9.04 Nvidia GeForce2 MX 100/200 Display adapter Win XP works fine, albeit very slow, with no problems. |
Take a look in your logs in /var/log. You may be able to troubleshoot from there. A good starting place would be:
Code:
tail -50 /var/log/Xorg.log.0|less |
how about posting the log along with ur xserver file
|
I'm sorry, I don't understand what you are telling me to do. Are you suggesting that I should break the boot process and enter those lines of code on the command line? Please forgive my ignorance-I'm completely new to this. Also, since I finally got the computer to the desktop, is there a way to check for errors from the GUI? I'm certain if I shut the computer down I won't be able to boot it again.

I'm suggesting that since you're still logged in, you enter those commands and have a look through them. Those are the logs for the X server, and kernel messages. Any problem will likely be in those somewhere, they should be easy to see.
The first command Code:
tail -50 /var/log/Xorg.log.0|lessThe second command Code:
tail /var/log/messages.1We're using these files, and not the upto date ones, because these should document the last file prior to the one in use, as in; the ones that failed. |
Thanks James. I tried entering these two commands and I just get a blinking square cursor. Do these commands take a long time to complete? I tried closing Terminal window and I get "Close this window? There is still a process running in this terminal. Closing the terminal will kill it."
A little more history: After dealing with this problem for many hours, I tried to reinstall Ubuntu from the CD. It won't let me do that. I was able to boot into Live CD one time and I got all the way to the GUI. Then I shut down and tried again to reload from CD - no deal. It was several boots after that that I got completely booted to the GUI, where I am now. It seems odd to me that I can't just reload from CD. It makes me think Ubuntu doesn't like something in my hardware, but I don't know what. I still haven't got a report ... Michael |
I just opened a new Terminal window and reentered the first command. This what I got: "tail: cannot open 'var/log/Xorg.log.0' for reading: No such file or directory (END)

A blibking cursor... Neither of those should give you a blinking cursor, so that may point towards a different error all together. Whilst running those commands, run something like 'top' as well; see what happens on there, see what it is doing.
Perhaps some hardware background too, see if there is anything in there that we can pin EDIT: Sorry, thats my fault, I mangled the filename: Xorg.0.log.old |
Here is what I get:

James - What is "Top" ?

heycan u please post the screen section of this file
/etc/X11/xorg.conf i am having doubts on this part of ur log LoadModule: "evdev" also please do one more thing from a shell type startx u need to pipe the output to a file post the output here please it will help to debug |
Hi Ankscorek. Here is what I get:
michael@BigDell:~$ tail /etc/X11/xorg.conf Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection I don't think I know how to do the other thing you asked me to do ... sorry for my ignorance. Also, I'm thinking maybe I have a bad CD for Ubuntu 9.04. I compared the md5sum from the Ubuntu communtiy website with the CD and they don't match. I used the checksum in the md5sum.txt file on the CD. Today I downloaded Xubuntu and I'm trying it on another computer before I try installing it on the problem pc. |
When I try the "startx" command, I get a message "X: user not authorized to run the x server, aborting
I tried this command with and without redirection michael |

---------------------------------------------- This may not work for you but this is what I did or close to it. I did a network install with the minimal cd. Hardy does not do a good job of detecting the video card. The other distros might be having the same issue. When i did the reboot, the machine came up with a blank screen, I had to go into terminal 1 to see what was going on. linux actually loaded fine except for the video. I had to dl two kernel modules mach64 and drm (thank god someone had already compiled them). did a depmod -a. Then I had to sudo apt-get install xserver-xorg-video-ati-dbg. Last of all I had to manually set the freqs and res in xorg.conf. I would not wish what I had to do on a new user (I consider myself a novice). Looking at /var/log/Xorg.0.conf and a lot of google research helped.
