I tried upgrading the Ubuntu on my trusty netbook and found 11.10 was way too slow. So I switched to xubuntu by installing the xubuntu-desktop package and then following the crazy instructions here : http://www.psychocats.net/ubuntu/purexfce

Now when I try to start up I get the xubuntu load-screen. But then my screen starts flashing between text mode and blank.

Text mode starts with the ominonus line

could not write bytes: Broken pipe

and then continues with further startup info about PostgreSQL, Apache etc.

After it reaches the line

* Checking battery state...

it freezes. The flashing stops but no GUI seems to load.

I can still get into the machine using CtrlAltF2 etc. But not much idea how to fix this.

Has anyone else tried to revert to pure XFCE with Oneiric and come up against the same problem?

OT question: what are you using Apache and PostgreSQL on a netbook for? Did you intend to install them? –  jw013 Feb 14 '12 at 17:15

I had a similar problem after I installed Xubuntu 11.10 on my computer. I didn't see the flashing between text mode and blank, but after the bootloader started to load the OS, the graphical splash screen suddenly disappeared, to be replaced by text-mode output on the boot process. I don't remember if I saw the could not write bytes message, but the final message written on the screen before the process froze was * Checking battery state...

I googled for help, and found this post: http://ubuntuforums.org/showthread.php?t=1859820

The solution given on that page was to do the following:

  • Press Ctrl+Alt+F1 to get to a text-mode login prompt.
  • Log in.
  • Command sudo apt-get install --reinstall nvidia-173
  • Command startx

When I did this, I got to the graphical login screen, and everything worked thereafter -- but only up to the next boot. My computer has an Nvidia graphics card, and for some reason, the drivers that come with the Xubuntu 11.10 distribution don't play well with it. (Someone on the ubuntuforums thread claims that it's due to "the kernel update from 2.8 to 3.0".)

As I said, this worked only up to the next time I booted; then I got the text-mode boot process display again, ending with the line * Checking battery state..., and then had to perform again the actions listed above.

Just now, I just read the ubuntuforums thread again, and noticed that someone advises that for 64-bit machines, such as mine, one should also reinstall the package nvidia-current. If that is the case (and perhaps in any case), you should probably try this:

  • Press Ctrl+Alt+F1 to get to a text-mode login prompt.
  • Log in.
  • Command sudo apt-get install --reinstall nvidia-current
  • Command sudo apt-get install --reinstall nvidia-173
  • Command startx

However, before I tried that, I solved the problem with my machine like this (note: this is in addition to reinstalling package nvidia-173):

  • I edited the file /etc/default/grub, and removed the comment character # from the start of the line #GRUB_TERMINAL=console. This will make GRUB2 use text mode instead of graphics mode when using the display. (I did this because GRUB2 was confused about how many lines were available for it in graphics mode, causing the text to scroll only after plenty of lines were "displayed" below the bottom edge of the screen.)
  • I'm not sure if this has something to do with the solution, but earlier, I had already commented out the lines GRUB_HIDDEN_TIMEOUT=0 and GRUB_HIDDEN_TIMEOUT_QUIET=true in /etc/default/grub, in order to get the GRUB2 menu appear in the first place.
  • I commanded sudo update-grub (necessary to take into use the changes done to /etc/default/grub).
  • I rebooted.

For some reason, the boot problem went away.

If you see this answer, please try it and let us know if it helped you.

Thanks for this answer Teemu. To be honest, I ended up going back and installing gnome / Unity and then Unity 2D rather than persevering with xface. –  interstar Apr 15 '12 at 18:17
    
I will have another look at that grub file though when I get a spare moment. Thanks. –  interstar Apr 15 '12 at 18:18
    
Cool, you're welcome. –  Teemu Leisti Apr 15 '12 at 19:05
    
By the way, I recommend persevering in trying to get Xubuntu up and running. The Unity desktop is just silly, and Xubuntu offers a nice, normal desktop. I liked the default "greybird" theme, except for the windows, where the controls are grey-on grey; so I used Window Manager to change the windows theme to "bluebird", which looks quite nice. –  Teemu Leisti Apr 16 '12 at 23:24
