Just happened without those options. But I'm not sure if it's a kernel bug, or a hardware/cable bug. Gotta investigate more I guess. It certainly happened less, the last two days have been issue free, but maybe I unplugged more and the cable got cleaner or something.
** Summary changed: - External monitor turns off for short period of times / until moving mouse when using kernel options i915.enable_gvt=1 intel_iommu=on + External monitor turns off for short period of times / until moving mouse -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1822854 Title: External monitor turns off for short period of times / until moving mouse Status in linux package in Ubuntu: Triaged Bug description: In disco; I have this issue where my external monitor (a ThinkVision P24h-10) connected to my ThinkPad T480s turns off for short times while actively working on the system. I noticed that if I don't move my mouse at all while it's off, it stays off. The T480s is connected to the monitor via USB-C; the monitor provides DP, USB, and Power over that connection. When the display turns off, USB devices continue working. I have attached /sys/debug/dri/0 output from when the monitor was off (a) vs on (b). Other related bits: * This also happens on HDMI, but much less often * There are no log messages when the display turns on/off in the journal.
