I have installed the alpha-1 version of 'natty' 11.04 on a Hewlett-Packard system originally sold as "Microsoft Windows XP Media Center Edition 2005", and updated the Ubuntu software up to this morning. Often it will not complete startup of Xorg - in this case, the screen is black except for a narrow white band at the top. The failure is shown in Xorg.0.log.

The display controller is: VGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2)

I installed the 32-bit Dec 2 alpha-1 version of 'natty', then updated this (see below for problems encountered).

Ubuntu version and kernel version
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.04
DISTRIB_CODENAME=natty
DISTRIB_DESCRIPTION="Ubuntu natty (development branch)"
Linux hp 2.6.37-12-generic #26-Ubuntu SMP Wed Jan 5 18:42:49 UTC 2011 i686 athlon i386 GNU/Linux
model name : AMD Athlon(tm) 64 Processor 3800+
cpu MHz : 1000.000

Installation was a hassle. I tried daily builds from the 12th and 18th of January, and ran into various problems: First, I couldn't partition the disk, due to a strange MBR (apparently) from the MS-Windows software on the computer. Then, one of the installers simply hung at some point. Finally, I partitioned and formatted the disk with a Puppy Linux CD, then installed from the December 2 original Alpha-1 'natty' CD. I did re-format the partitions I had created with Puppy, to make sure there wasn't any incompatibility in file-system details. After this, I updated the system, at around the 18th or 19th of the month. I installed openssh-server so that I can access the system over my LAN, when Xorg won't start.

I haven't tried a 64-bit version yet, and don't really plan to do so.

I'm attaching a tar file with /proc/cpuinfo, /proc/meminfo, lsmod output, lspci output, Xorg.0.log, and Xorg.0.log.old

I installed the nvidia driver recommended when the Gnome session first started.
