I daul-boot Windows XP 32 bit and Ubuntu 12.10 64 bit. I have been having problems waking up after suspending (sleeping) on both OS's. On Ubuntu it shows a black screen with an a weird error message for about 6 seconds and then goes to the normal unlock screen. In Windows, it just shows a black screen with no error message for 6 seconds, and then goes to the normal Windows unlock screen. Please help me this is getting really annoying. Thanks!
