I am not a tech/ expert ,but experiment with all type linux and different flavors of ubuntu .What I know is bios not reboot automatically ,every time i open system, i have to reset bio. The system has very severe remote interference and do not have a stable status. Becasue of my driving experience (ignorant certainly), I manage some how this desktop and run things.:-) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1550779 Title: [Lenovo ThinkPad X220] *ERROR* CPU pipe A FIFO underrun - Xorg glitches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1550779/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
