I tried GDM just before the whole thing went bang, made no difference, just tried log out again with this fresh install but still no good, now I just get a black screen for a few minutes then the PC shuts down ??? one of lifes little mysteries I guess. It's not important, as far as it goes, just something doesn't work correctly so it's like a sore tooth LOL.
BTW. I'm just about to do the QQ upgrade, that fix you posted, I assume I run that after the upgrade/update before I reboot. ??
