I was able to simplify this a bit: 1. Add nomodeset to kernel command line. 2. Remove all xorg video drivers except the VESA driver. 3. Add "blacklist nouveau" to /etc/modprobe.d/blacklist-nouveau.conf. 4. Run "dracut --force" to rebuild initramfs with new blacklist entry. This avoids the requirement for a hard-coded xorg.conf. I previously had trouble keeping the nouveau module from loading. I had forgotten that it is necessary to rebuild an initramfs to ensure the system does not load blacklisted modules. -- Mike :wq -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

These have the advantage (if they work) of (a) not changing the basic config so a better driver can be easily tested, and (b) being easily by boot line edit tested before making any changes which need file edits. > 3.

Re: [Fedora-xen] kernel-2.6.32.10-1.2.92.xendom0.fc12.x86_64 X broken on MacBook
Kernel been built on branch xen/stable-2.6.32.x checked out via JF's Git Repo does work with DRM enabled under Xen 4.0-rc7 on F12. (Radeon HD 4650). Appears to be 2.6.32.10 in meantime. How much sense does make using rpm's based kernel with "nomodeset" option ?

I tried adding nomodeset, but that did not help by itself. I ended up doing the following: 1. Add nomodeset to kernel command line. 2. Create an xorg.conf that uses the VESA driver (X -configure, edit). 3. Deactivate dri2 and dri in xorg.conf. 4. Boot Xen Dom0 kernel into runlevel 3. 5. rmmod nouveau; init 5. This works (of course, the VESA driver is not optimal). -- Mike :wq -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
