Kernel oops and low graphics in Lucid since 2.6.32-16 kernel

Postby ingo2 » 9. Mar 2010, 22:03

Does anybody observe the same problem (VBox 3.1.4 PUEL):

Since yesterday's kernel update to 2.6.32-16 in Ubuntu 10.4 (Lucid) I continuosly (after every boot) end up with "low graphics mode" and getting kernel oops. have meanwhile also reported this bug to Launchpad. Problem was never observed with any previous kernel including 2.6.32-15.

However seems that nobody sees this problem on real hardware

Host: Hardy-amd64
Guest: Lucid-amd64, 2 CPU's, 2GB RAM, GA installed.
xorg.conf is correctly adopted for VBox,

Did you re-install the guest additions after the kernel update?

I did try to re-install GA's, but that didn't change anything.
Moreover DKMS has handled that perfectly in the past and over several kernel updates.
I also reported that issue (via apport) in Launchpad, see here: https://bugs.launchpad.net/bugs/535297

Yes it does not work. (64bit) anyway not sure about 32 but it would probably fail as well.
hold the left shift down and boot to the previous kernel. From what I am seeing the ones that did the partial update got hammered again.
You should never allow a partial update to run on your OS.

Thanks for confirmation, so I'll wait for the missing part of the update. It's a mess, how they do it in Ubuntu, with Debian (i.e. Squeeze) I never had that issue. There is no indication whether the update is partial in Ubuntu, in Debian -YES!

P.S.: booting kernel -15 is fine, forgot to mention that

Wow, I am getting forgetful in my old age. I had the same problem about 3 weeks ago with an Ubuntu 9.10 guest, albeit with a different kernel version. I think it was 2.6.31-19. I kept having to boot into grub to boot the -17 kernel.

I finally un-installed the -19 kernel and apparently blotted that painful episode from my memory.

This little annoyance seems to be more then just a partial update problem. The deprecation of hal might be causing this as well.
Either way the kernel definitely has problems.

From changeLog 2.6.32-16.23 entry
* update DRM to mainline v2.6.33


Does this mean Virtualbox hasn't been updated to work with 2.6.33 yet?

Alas! it is several days since I noticed that, after the passage 2.6.32-16 and instead of looking I should have come here ... :cry:
too bad for me, but I would like the next kernel version put everything in order (it should not delay) :wink:
Anyway, thank you for the information

Thanks Frank for the hint!

The proposed patch in vboxvideo_drm.c works fine here with Lucid-amd64 and the new 2.6.32-16 kernel.

Please at this occasion allow me another question:
Is the stange mouse beheaviour (missing arrows when trying to resize windows or unability to move objects on the desktop or dead 3rd mouse-button) also caused by the GA's or by the patches/hacks of Canonical?

OK, it works super well with ubuntu 10.04 in the problems of low resolution and resizing!
However, still a little something I am still obligated to make every time Ctrl right to use the mouse outside the window ...
Is it possible to also have a patch over there before the release of ubuntu 10.04?
Thank you

Scheduled in the next maintenance release due out soon from what I understand.
You can get around this by creating /etc/X11/xorg.conf and adding the following until the release.
Code: Select all   Expand viewCollapse view
Section "InputDevice"
        Identifier  "VBoxMouse"
        Driver      "vboxmouse"
        Option      "CorePointer"
EndSection

Log out and back in for it to take effect.

Hum! When I made the changes in xorg.conf, I can actually go out of my window, but then it is not resizable! There is something on in there but I do not see what ...
