Comment 7 for bug 977547

Finally switched to xdm and the first login screen was shown.

Tried numerous things, which all did not work:
- Kernel parameter: nomodeset (Display did not come up at all)
- Kernel parameter: acpi=off nolapic noapic
- Blacklisting Framebuffer-Driver in "/etc/modprobe.d/blacklist-framebuffer.conf"
- Added 'Option "VGAAccess" "true/false"' in xorg_seat0.conf
- Added vt7 ond or -isolateDevice to X command in lightdm.conf
- Changed minimum-vt to 8 or higher in lightdm.conf
- Added 'chvt 7' to display-setup-script

Spent lots on hours on that... xdm is not very cute, but works. Current gdm is told not to support multiseat. kdm was no choice for me, because there is no other kde-stuff on that system. May be lxdm is an alternative until this bug is fixed.
