On my new desktop machine I'm having dual monitor setup. Sometimes one of monitors gets black for a second and then shows image again - this is especially visible on logon screen. Also, when running an OpenGL application, if it starts on one specific monitor, the whole screen flickers quite badly with random rectangles starting at mouse cursor position. If same app starts on another monitor, no flashing occurs. Vulkan demo apps also don't exhibit flashing.
OS: Ubuntu 16.10 64-bit Kernel: 4.8.0-26-generic CPU: Intel Core i7 6700K GPU: HD Graphics 530 (Skylake GT2) I always edit my /etc/X11/xorg.conf as: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "true" Option "DRI" "3" EndSection By the way, when tried installing Xenial, it wouldn't even work with dual monitor setup, when adding above settings (works perfectly fine on Haswell desktop). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634449 Title: Black flicker when leaving monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634449/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
