Same problem here: Laptop is a HP 255 G6 based on AMD E2-9000e, Ubuntu is 18.04 64 bits, kernel 4.15.0-45-generic, wide monitor is LG LG 25UM58-P, 2560x1080.
It does not always flicker, but it does when playing video or when using applications in full screen mode (or in general when using most of the surface of the wide screen). Monitor is connected through HDMI, other monitors with lower resolutions do not flicker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791312 Title: ubuntu 18.04 flickering screen with Radeon X1600 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791312/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
