Bug Description
I will take photos and attach to this bug later. Every few hours I'm forced to reboot due to screen corruption which may be due to flaky 3D or acceleration support. When doing video-intensive things like Skype/Hangout video call the current window will disappear behind the browser and show up inside the Unity Launcher. Eventually I can no longer type or use the mouse and the system will reboot itself.
An additional data point is that, when I first tun on the system, it takes about 3 seconds to draw the Plymouth screen and, if grub asks me to pick a boot option, about 5 seconds for the grub screen to draw from the bottom up (which makes me believe it might be poor acceleration support).

Ellen Arnold, thank you for reporting this and helping make Ubuntu better. As per http:// support. lenovo. com/us/ en/products/ laptops- and-netbooks/ yoga-series/ yoga-2- pro-lenovo an update to your computer's buggy and outdated BIOS is available (76CN41WW). If you update to this following https:/ /help.ubuntu. com/community/ BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
For more on BIOS updates and linux, please see https:/ /help.ubuntu. com/community/ ReportingBugs# Bug_reporting_ etiquette .
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.
Once the BIOS is updated, and the information above is provided, then please mark this report Status New.
Thank you for your understanding.
