Re: [Xen-devel] Desktop Environment/GUI Cannot Start After I Have Installed Xen 4.1.3-rc1-pre and Linux Kernel 3.3.0-rc7

["Teo En Ming (Zhang Enming)" <singapore.mr.teo.en.ming@xxxxxxxxx>]

Hi,

I have solved the problem. Xen 4.1.x is incompatible with the onboard graphics of Intel DQ45CB motherboard. I have switched the graphics adapter to NVIDIA 8400 GS PCI Express x16 and the combination of Xen 4.1.3-rc1-pre, kernel 3.3.0-rc7, and NVIDIA 8400 GS works well (Xen 4.1.x is compatible with NVIDIA 8400 GS graphics).

I have also compiled the *latest* linux kernels 3.x.x for Ubuntu 11.10 Final Release for you to use. You may download the *latest* linux kernels from the following links:

(1) linux-image-3.3.0-rc7-xen-teo.en.ming-sgp_14.mar.2012_amd64.deb

Dear All,

I have just compiled and installed Xen 4.1.3-rc1-pre and the latest Linux kernel 3.3.0-rc7 in Ubuntu 11.10 Final Release. I am able to login to my Desktop Environment/GUI when Linux 3.3.0-rc7 is *enabled* and Xen 4.1.3-rc1-pre is *disabled*. However, when Linux 3.3.0-rc7 and Xen 4.1.3-rc1-pre are both enabled, I am unable to start the default desktop environment/GUI. The menu bar and status bar in Unity won't show up. Although I cannot login via the GUI, I can still login through the text console/terminal. I am able to see that Xen is running properly by executing the command "sudo xm list". "xm list" shows that Domain 0 is running properly. It's just that the Desktop/GUI won't start up.

The errors which I think are the most important are reproduced below:
