Hey, I just figure out that all of use, who encounter this problem, are using a similar/same graphic card, the Intel Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller.
I tested Ubuntu Lucid on another laptop with an integrated ATI graphic card, this issue doesn't exist on it though. that laptop can sleep correctly by closing the lid. Also it can wake up successfully. However, it's screen keeps flashing after wake up though. That's probably a problem related to the driver though, (maybe plymouth also have something to do with.) is it the intel driver's problem or the plymouth? -- Lucid freeze after close lid https://bugs.launchpad.net/bugs/538521 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
