Hi, I had the same problem (poweroff after resume) with the TravelMate 5320 on Arch Linux with 2.6.24/25. I have Intel GMA965 with Broadcom wireless...
This is what I did; disable module autoloading, remove any custom modules loading, boot to init 1. Then suspended to acpi 3, the system resumed. Clearly a module was the problem... being that my system usual has around 100 modules loaded it was a pain, but I finally found it. It was one single module that was causing this - psmouse. Depending on your hardware you could have other problems like backlight stays off, aditional broken modules... there is a nice package "hibernate-script" which is a wrapper around diffrent suspend schemes like tuxonice and uswsusp. It allows you to unload modules, unmount filesystems, kill daemons... - prior to suspending, and reloading modules after resuming. I don't usually track Ubuntu bugs so if you see that someone is having these troubles (poweroff after resume) with Acer laptops try to suggest to unload psmouse for a start. -- [Hardy] Laptop can't resume from suspend https://bugs.launchpad.net/bugs/235315 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
