FWIW, I talked to Ken (Chung-chieh) Shan about this issue just now, and I agree there may be different issues: the problem I originally reported was an almost immediate lockup on starting X (if the virtual size was too big and without the NoAccel option), while Ken still observes a lockup when he logs in, when 'mail-notification' starts and puts up a pop-up window. (I don't use that tool, so I wouldn't have seen that issue.)
(We also have different hardware: an HP nc6220 for me and a Lenovo ThinkPad X60 for Ken.) Peace, Dylan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
