[Kernel-packages] [Bug 1822854] Re: External monitor turns off for short period of times / until moving mouse when using kernel options i915.enable_gvt=1 intel_iommu=on
Marking this as Triaged / Low, as it seems to be only caused by these unusual options. ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- 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 when using kernel options i915.enable_gvt=1 intel_iommu=on 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.
