Ok I faced wit the same problem here. I got Intel Centrino but with Ati X300 graph.card on acer aspire 1652wlmi. After fresh setup the system suspended and woke up each time, but after updating some things it had all the nice black screen syndroms.
Some important things Do not use any proprietary drivers from Ati (fglrx) or Intel, ok you can have beryl but you wont be able to wake up after suspend. I don not know if it s a bug or else, but when you have something attached through USB the ntb wont suspend, it is idependent from used kernel. If you have any IPW2100,IPW2200 (found out with theese two) chipsets you need them unload them before going to suspend (blacklisting /etc/defaults/acpi-support) Next thing edit /etc/defaults/acpi-support and change sleep (S3) to stand-by (S1) it takes more battery but its more "compatible" So I have kernel 2.6.18.5, with standard radeon kernel driver and Mesa, and changes in configuration files mentioned above, I also have to detach my USB wireless keyboard before going to suspend. And everything works fine... Ok this works on Acer Aspire 1652Wlmi with ati x300 graphic card which has a Intel Centrino technology. -- Intel 9XX Chipsets fail to suspend https://launchpad.net/bugs/67710 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
