Also, FYI: There are no log messages when the display turns on/off in the journal.
** Description changed: 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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1822854 Title: External monitor turns off for short period of times / until moving mouse Status in gnome-shell package in Ubuntu: New Status in linux package in Ubuntu: New 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.
