    Boot failure after update

    Firstly, I apologise if this has already been answered somewhere, but various attempts at searching Google and the Forum Search haven't turned up anything useful.

    I recently installed Kubuntu (Dapper) to my laptop, and it worked more or less OK. (Screensavers wouldn't load, all music players repeated the first .2 seconds of anything I played until killed, but...most of it worked.) A few days later I went round a friend's house to use his internet connection to update/install things to Kubuntu. Among the installs and updates was (from what I can see) a kernel update. However, now when I boot the laptop and see:

    Ubuntu, kernel 2.6.15-27.386
    Ubuntu, kernel 2.6.15-27.386 (recovery mode)
    Ubuntu, kernel 2.6.15-26.386
    Ubuntu, kernel 2.6.15-26.386 (recovery mode)
    Windows XP


    I thought it was strange how the kernels piled up like that on the GRUB menu, but OK. However, when I select the new kernel and try to boot, I get the usual logo and progress bar, and it flicks through all the stuff booting it, until it finishes. Then I see a _ shell cursor on a black screen for about a second, then it goes back to the kubuntu logo and progress bar and does absolutely nothing. Won't respond to any mash of keyboard presses (tried things like Ctrl+Alt+Backspace), the only thing that gets any response is pressing my laptop power button, then the progress bar starts lighting up and all the shutdown commands roll past the bottom and it turns off.

    The same thing happens when I select the old kernel from the boot menu. I can boot into recovery mode though.

    So, simple question - can anyone offer any advice? Or a link to a magic fix for hundreds of others who've had my problem? Any help would be appreciated.

    P.S. Sorry for the long post, I thought I may as well get all the details down.

    in recovery mode enter your password then try

    dpkg-reconfigure -phigh xserver-xorg

    then reboot ...

      Thanks for the help. I got this:

      Code:
      /usr/sbin.dpkg-reconfigure: xserver-xorg is broken or not fully installed
      X server broke itself then? I guess I fix it by doing some command line apt-something work? What should be the command?

      I tried a simple apt-get install xserver-xorg, and now luckily I have everything back to normal. Plus my sound now works, so I guess updating the kernel is still usually a good idea.
