ubuntu 10.10 beta netbook 386 hanging under Virtualbox

[Hadmut Danisch]

Hi,

I just wanted to give the 10.10 beta netbook 386 edition a try.

I am using a 10.04 amd64 host system, running Virtual Box (not the OSE version that comes with ubuntu, but the extended version taken from virtualbox.org), created a new machine with 5GB of hard disk and booted from the cd image as virtual disk.

Installation worked smoothly and without any problem. (selected to auto-login)

But after installation, the GUI hangs after starting X11. There's nothing but the background image. The machine itself is not dead; when sending an acpi shutdown, it properly shows the regular selection menu what to do and shuts down in the regular way.

Unfortunately I cannot check what the problem is, since I did not yet find a way to get a console:

Whatever I press at boot time, grub does not provide a selection menu, but directly jumps into booting. Usually pressing the shift key is the way to get a grub prompt, but doesn't work.

Once the X11 is up, there is also no way to get a prompt. Sending a Ctrl-Alt-F1 is also without effect (Under VirtualBox the way to send this is <Host Key>-Fx, but there is no visible effect.)

So I don't see even a way to get into the system for debugging.

Since X11 itself runs, it could possibly be a problem with the default resolution smaller than a netbook screen. However, life would be easier if there was any way to get a regular command line login prompt.

Funny detail: The autolock works. Although there is nothing on the screen but the background, the auto screen lock locks the display after some time, and properly asks for the password. But then, you are at the empty screen again.

OK, I got some steps further.

Got the grub prompt, you just have to hit a very small time slice with pressing the button. Now got ssh access.

- apt-get upgrade to lastest packages does not help.

- problem seems to be that there is no window manager running.

  env DISPLAY=:0.0 xlogo

  works, but produces a borderless logo, typical for missing windows manager.

- Am I correct that mutter is the window manager supposed to run under netbook edition?

env DISPLAY=:0.0 mutter
failed to create drawable
Fensterverwalter-Fehler: Unable to initialize Clutter.

OK, I found the problem, strace helps:

The last actions before printing the error message are several file access methods to /usr/lib/i486-linux-gnu :

...
1290 open("/usr/lib/i486-linux-gnu/i686/sse2/libtxc_dxtn.so", O_RDONLY) = -1 ENOENT (No such file or directory)
1290 stat64("/usr/lib/i486-linux-gnu/i686/sse2", 0xbfe2c4b4) = -1 ENOENT (No such file or directory)
1290 open("/usr/lib/i486-linux-gnu/i686/cmov/libtxc_dxtn.so", O_RDONLY) = -1 ENOENT (No such file or directory)

1290 stat64("/usr/lib/i486-linux-gnu", 0xbfe2c4b4) = -1 ENOENT (No such file or directory)

there is no /usr/lib/i486-linux-gnu
there's just a /usr/lib/i686-linux-gnu

And there is no libtxc_dxtn

Hello Hadmut
Have you verified md5 sums of downloaded images?
Are you runnig VM on a processor that support hardware virtualisation (-v or -vt)?
Can you use testdrive instead?
Thank you for taking the time to report this bug and trying to help make Ubuntu better. However, it seems that you are not using a software package provided by the official Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!

If you are interested in learning more about software repositories and Ubuntu the following pages should be informative:

1. http://www.ubuntu.com/project/about-ubuntu/components - information about Ubuntu repositories
2. https://help.ubuntu.com/community/Repositories - information regarding managing repositories

[Hadmut Danisch (hadmut)]

It is really improbable that a download mistake would allow a regular installation run and then cause such an error. But yes, I've checked on your request, and the MD5 is correct.

Yes, the machine has hardware virtualisation. But actually I am not sure whether VirtualBox makes use of it.

What does "use testdrive instead" mean?

What does that mean "not using a software package provided by the official Ubuntu repositories" ? It is the official 10.10 beta netbook image. Nothing else. Should run under any virtual machine (and the virtual machine can't be the reason for missing files).

I have the smae problem with an updated and clean install of netbook edition.
The regular gnome desktop works fine, seems like the problem is only related to the new netbook UI, witch was what I needed to test, sadly :-(

[Njcki (man-techno)]

The problem exists. I can't find a solution
