After I remove fprintd and fprintd-pam rpms GDM works OK on the Xen pvfb and I can login to the desktop. However there's a different problem with F17 HVM guests. There Xorg doesn't start at all. "X startup failed, falling back to text mode" when I try to boot the F17 DVD installer .iso. Also "Starting Show Plymouth Boot Screen..." is [FAILED]. When I run "X" manually from the console I get this in Xorg.0.log: LoadModule: "xaa" Warning, couldn't open module xaa UnloadModule: "xaa" Unloading: xaa CIRRUS: Failed to load module "xaa" (module does not exist, 0) UnloadModule: "cirrus" .. Fatal server error: no screens found .. Server terminated with error (1). So it looks like Xorg requires xaa module for cirrus, but it's not there anymore. I guess this is related to the DRI2Only-feature in F17 ? http://fedoraproject.org/wiki/Features/DRI2DriversOnly -- Pasi -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

[Fedora-xen] Fedora 17 testing as Xen VM / Xorg issue
Hello, I just did some installs with F17 RC4 (the GA version) as a Xen VM. Xen host/dom0: RHEL 5.8 x86_64 with the included Xen rpms. Tested F17 RC4 VMs: - 32bit F17 PV domU: graphical GUI install works OK using the Xen vfb/pvfb but Xorg fails to start during normal boot after installation. - 64bit F17 PV domU: graphical GUI install works OK using the Xen vfb/pvfb but Xorg fails to start during normal boot after installation. - 32bit F17 PVHVM guest: X fails to start so VNC install must be used, install works OK thru VNC. Xorg fails to start during normal boot after installation. - 64bit F17 PVHVM guest: X fails to start so VNC install must be used, install works OK thru VNC. Xorg fails to start during normal boot after installation. (PVHVM == HVM fully virtualized guest with optimized Xen PV drivers. Optimized Xen PVHVM drivers are nowadays included and used as a default with recent upstream Linux kernel versions (2.6.36+), so disk/net IO doesn't have to be emulated by Xen Qemu-dm.) I wonder if the problem with X failing to start is related to: http://fedoraproject.org/wiki/Features/DRI2DriversOnly Xen HVM guests have Qemu-dm emulated Cirrus VGA adapter (or stdvga) visible to the VM.. which doesn't have DRM/KMS drivers, and I think it's the same for xen-fbfront. I think I saw Cirrus (Qemu) DRM/KMS driver being worked on dri-devel mailinglist.. Any ideas/comments? -- Pasi -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
