Hey all, I've been trying out the new tabbed layout and it was working really well for about 2 hours, then it suddenly just started killing my X for some reason. What I was finding was that as soon as I switched screens my session would die (dropping me back to the gdm login page). It would also do this if I switched to a workspace > 5. Weird eh ? I'm using the darcs head for contrib, xmonad and x11-extras, so I pulled the latest (again, just to be sure) for them and no updates. I'm also using Feisty Ubuntu as my OS if that makes any difference. I rebuilt and reinstalled, no luck. As soon as I dropped the tabbed module out and rebuilt/reinst xmonad it's all back to working again (albeit sans tabbing which I really REALLY miss now already :-) ). Not being an X guru, and not very up on haskell, I'm not sure how to try and debug this ... can anyone suggest how I might try and track this problem down ? Cheers Dave
