Every time I get this error (about once a week or less) dmesg has the following message: "*ERROR* invalid framebuffer id". I have been careful to check if the framabuffer error happens at the same instant I see the bug manifesting itself and it does.
Lenovo X220 with Intel graphics. I have the laptop to do nothing when lid closes on AC power, sleep when lid closes on battery. But it was already happening when the computer was set to always sleep when lid is closed (I changed exactly to avoid hitting this bug too often). My guess is that this bug is being triggered by some sort of sequence of lid opening and closing and AC power going on and off. Also, I have the bug happening twice by closing and instantly reopening the lid (but still, I can't find a way to reproduce the problem). I am not seeing any correlation between time computer has been left with lid closed (whether it is sleeping of not) and chance of this bug manifesting itself (except for the instant close-then-open case I mentioned above). Of course these are anecdotal observations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: Resume from suspend leaves me with black screen or a screen of the desktop before it suspended (though the mouse still moves/changes cursor) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/966744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
