[Bug 1327110] Re: [Dell Latitude D420] Black screen after resuming from suspend
That is true. And it happens after I type my password to unlock the computer. I tried turning off password lock during suspend in the power options and then it works. So the problem only happens when the computer resumes from suspend after the laptop lid has been closed and screen is locked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327110 Title: [Dell Latitude D420] Black screen after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1327110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1327110] Re: [Dell Latitude D420] Black screen after resuming from suspend
On the fifth trace suspend I got the picture back on screen but the computer totally froze, not even REISUB would restart it. This is a bit different from when I close the laptop lid because then the computer keeps working but I get a black screen until I restart lightdm. Attached is the dmesg output after that hang, perhaps it can help. I do find this which seems to be similar to what I'd expect to find according to the resume t race instructions in your link.

[Bug 1327110] Re: [Dell Latitude D420] Black screen after resuming from suspend
OK, so I think I haven't been totally clear in the description of this bug. Here is some clarification. - If I do Suspend from the menu and power back on, it works - If I lock the screen from the menu and unlocks it, it works - If I close the lid of the laptop, the computer resumes and the username and password dialog appears. But after I have typed in my password, the screen goes black but the computer keeps working. If I restart lightdm, it works To me this doesn't look like a suspend/resume bug at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327110 Title: [Dell Latitude D420] Black screen after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1327110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did a suspend according to point 4. But resume worked and I couldn't find anything matching the instructions in dmesg.txt. ** Attachment added: dmesg.txt https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1327110/+attachment/4126592/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327110 Title: [Dell Latitude D420] Black screen after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1327110/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
