Hi Herton, Tried the latest kernel you uploaded, and I'm seeing the same behavior (blank video on resume).
I tried the following: with the system in that state, I asked it to suspend (not hibernate). On resuming from the *second* suspend, the backlight turns on fine and the system works normally. I went back to the -4 kernel we tested the other day, and I confirmed it has this behavior too, i.e. the first suspend attempt fails to restore screen backlight upon resuming, but the *second* attempt succeeds. This information will hopefully be helpful. This however is behavior that will baffle users, so I don't think we can even call this a valid workaround, the problem still remains. I'm attaching a dmesg file containing the two suspend/resume series of events. Also if there's any other procedure or information that might be helpful with this problem, please don't hesitate to ask; this system is used mainly for testing Ubuntu. ** Attachment added: "dmesg including initial boot and suspend/resume events." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/719620/+attachment/1864338/+files/dmesg-2.6.38-5-double-resume.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/719620 Title: Toshiba Tecra A11 - System doesn't resume after suspend -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
