Question X11 initializartion failed error after crash


Last night I was running Linux Ubuntu 10.4 and used my Firefox browser to find info on osteoporosis for my wife. I entered the following search string in Google search: osteoporosis reclast problems. At the very top of the returned results page was a sponsored result with a simple link: Reclast.com (WOT had it flagged with a green=OK icon). I clicked on it and immediately a bizarre page appeared. It said that my computer was infected with a long list of various viruses and malware. Several of its child windows were flashing and, most strange, one of its windows had a progress bar and said it was searching my Windows c:/... directory. I don't remember the whole pathname, but it included the words "..user" and "Microsoft". This I interpreted as very suspect since, when running Ubuntu, there is no such directory, although I do have Windows XP installed on its own partition so I can dual-boot.

The warning page also insisted that I needed to click on a link it provided that it stated was necessary to fix the problem. I didn't do that, because at this point I suspected that this was a dangerous page and I would possibly be inviting some malicious downloads if I followed the instructions and clicked the offered link. Instead, I used a kill utility to kill the entire Firefox browser ap. Firefox went away and I then ran Firefox again. The same warning page immediately appeared. Again I killed Firefox. I then decided to reboot Ubuntu to see if that would correct the problem. That's when things got worse.

I have a dual-boot system with Windows XP, Ubuntu 9.10 (2 kernels available), and Ubuntu 10.4 (3 kernels available), with recovery mode choices available for all the Ubuntu kernels. When I tried to reboot, the grub menu appeared like normal. But when I selected my default Ubuntu 10.4 choice, the boot process seemed to run normally but stopped at a splash page with a violet background and "Ubuntu" in large type with the five dots below. And it stayed there; the boot process never continued. The first time this happened, it did do a fsck of the HD, but then stayed hung at the splash screen. I tried to reboot again several times, but got the same result, except there were no more fsck checks that ran. I even left my computer on all night, in case the boot process was doing some type of lengthy processing in the background. Eight hours later, it was still stuck at that same splash screen.

I tried booting into the other grub choices. Windows booted completely normally. I ran a complete virus scan while booted into Windows, which found nothing wrong. I then tried booting into my Ubuntu 9.10 choice. It also booted completely normally (which is how I'm writing this post). However, ALL of my three Ubuntu 10.4 menu selections hang at the Ubuntu splash screen I described above.

Next I ran the recovery mode menu choice for my Ubuntu 10.4 kernel. That worked OK. While using that, I ran the utility to repair all packages, which seemed to rebuild everything. I also ran the choice to update grub, which seemed to run OK. Still, I was unable to get past the frozen splash screen when I tried to boot my 10.4 kernels.

Finally, I highlighted the Ubuntu 10.4 menu choice and pressed (e) to edit it. I removed the "quiet splash" options and then tried to boot. Much processing went by on a text screen and, in a short time, I was left at a login prompt on a terminal. I was able to login OK and the terminal mode seemed to work fine. I checked around and all the file system seemed to be there OK. But no GUI (it normally boots into the Gnome desktop).

Booting again into my Ubuntu 9.10 choice, I confirmed that the entire 10.4 file system is there and appears normal. I can access all the files and all of my data is still there intact. From the terminal I tried running several commands. (I also have the KDE desktop installed, although I normally work with Gnome). One possible clue to the problem is, when I tried to run Konsole from the terminal command line as a test, I got the following message:

Code:
KUnique Application: Cannot find the D-Bus session server: "/bin/dbus-launch terminated abnormally with the following error: Auto launch error: X11 initialization failed"
I checked and found that there is no "/bin/dbus-launch" file in either of the 9.10 or 10.4 filesystems, which seems strange. It seems that, since that bizarre virus warning page and my kill of Firefox and a reboot, the boot process fails to initialize the GUI mode. I have no idea why this is so, and my multi-boot system had been working fine for a long time.

Any help would be much appreciated. In the meantime, I'm going to backup all directories in my 10.4 filesystem in case I need to completely reinstall Ubuntu 10.4, so I won't lose any of my data files.

Konsole runs when X11 is running, because it runs as a shell-within a gui on a desktop environment such as X11, kde, gnome, etc. Since you were operating from a terminal, no X11 was running, so Konsole could not start.
Anyway try this-
Code:
# rm /tmp/*
# reboot
try rebooting twice, then if that doesnt work:
Code:
#apt-get remove gdm
#apt-get install gdm
when you reinstall make sure to reinstall any dependencies which may have been auto-removed alongside gdm
if that doesnt work try replacing apt-get remove with apt-get purge, and if that doesnt work try reinstalling gnome
make sure the computer is backed up before you try any of this!
