I am seeing the same behaviour on Quanta ZW9, it has Intel chipset and Ati graphics. Dan
It would be useful to know which "Ati graphics" chipset you have. /sbin/lspci will tell you what the OS is seeing as the graphics chip. We have two IBM/Lenova T42 laptops: one has ATI 7500, the other ATI 9600. The 7500 suspends to RAM and resumes nicely; the 9600 suspends, but comes back with a blank screen, for both X and the console windows. The machines is otherwise "live" as witness that it is possible to do a CTRL-ALT F2 to gain a text console; login as root; and execute "shutdown -h". All, of course, without seeing what you are typing, so you need to use the keyboard very carefully. I guess I posted a query to the fedora users' lsit (fedora-list@xxxxxxxxxx), but not yet bothered the development list on this. I would like to contribute to the debugging of this problem, but I first need a better understanding of how this all works. My plea to the users' list was for pointers to some background reading on how power management works. So far I have mainly garnered "me too" comments. I do have a natural aversion to attempting to fix the bug by the "try this, try that" method. I did do a few of things suggested in various bugzilla and other posts, e.g. change to /etc/acpi/events/video.conf and /etc/X11/xorg.conf. However, my preference is to enable some debugging at the "apropriate places" and find out what is really happening. Unfortunately, the laptop is needed in daily use, so I don't have the freedom to try fc6test3 at the present time. If anyone has some pointers to useful information gathering techniques for this problem, I would be interested. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
