Removing VESA from the kernel did the trick! After resume, X was rather slow for some operations. Not painfully slow, but noticeably slower than normal. I did nothing to the system but ran x11perf. After about 2.5 hours it completed. When I resumed use of the system, it seems to be back to normal. No idea what made it change. I am running Gnome2, so it is a very heavyweight system running 9.2-Stable from last Wednesday (r255013). I'm delighted to finally have a working resume. It's been YEARS since I've had it that works on any of my Thinkpads (600E, T43, T520). -- R. Kevin Oberman, Network Engineer E-mail: rkoberman@gmail.com
