So I have now tried the following: - Clean installation of Mageia 6 X86_64 on a spare HD (with the normal drive removed). XFCE desktop selected as the default. - Proprietary Nvidia driver to be installed during setup. - Installed X86_64 Trinity packages using urpmi and all Mageia 6 updates. - Reboot. - Login to Trinity. This crashed as before. - Change to framebuffer driver, reboot. Login to trinity, again the same crash. - Removed 'nokmsboot' from the boot parameters. Rebooted. Trinity crashed on login. - Wipe HD, reinstall again, saying no when proprietary driver is offered, nouveau driver installed. - Install trinity. Once again, it crashed on login. This seems to eliminate the possibility of the Nvidia driver or my NFS home directories causing the crash and leaves me with the conclusion that this is architecture related. I'm tempted to see if the i586 packages do any better in the interests of experimentation. Any thoughts, much appreciated.
