I have Virtualbox 3.1.4 r57640 installed on Windows XP as the host, Ubuntu 9.10 as the guest. And since the ubuntu is not being used as an active development currently, I decided to upgrade it to Ubuntu 10.04 Beta 1. Having read a lot of positive reviews for Lucid Lynx, I wanted to try it out as soon as possible.
The upgrade took more than a couple of hours. It downloaded a GB of package data from repositories, and then took 90 minutes to setup the new system. Usually my ubuntu upgrades have been quite a painful process, having to manually configure a few things and set another few right. But then these things are to be expected if you always jump the ship in the Beta mode.
Immediately upon restart I was faced with my first problem. The xserver failed to load and instead threw a dialog box saying it was switching to low graphics mode for the session. I let it do so. Logging in into the system, as usual, my VirtualBox addons needed re-installation. But even that did not solve the problem. The same error popped up again upon restart. Also, my mouse integration did not work.
The first problem was occurring due to the new kernal 2.6.32-16-generic. Looking up in the forums, I found that virtualbox will incorporated the fix in their next maintenance release. However, one could apply the patch manually. It required modifying the file:
/usr/src/vboxvideo-3.1.4/vboxvideo_drm.c
The fix is r27248. You can read up about the ticket here.
To get the cursor integration working, we need to create xorg.conf. Ubuntu has done away with xorg and are using hal now. I could not clearly understand the reason behind the problem, but re-creating the xorg.conf file does the trick. Here is the forum where this issue has been discussed:
Cursor Control in Ubuntu 10.04
I do not seem to be having any more issues. I’ll keep consolidating any issues I run into and how to fix them so that I don’t have to google them up every time.
