Leftover remnants appear after wake from suspend
I'm using v4.2 on Ubuntu MATE 18.04. I got DisplayLink working after applying these two workarounds. Disabling "pageflip" caused issue so I removed the line.
I have two monitors connected to my laptop. One connected via HDMI port and the other one via DisplayLink. Whenever the laptop wake from suspend, the DisplayLink monitor would exhibit: 1. Leftover remnants when I move a window around or switch workspace. 2. Blank wallpaper. 3. No issue on mouse cursor (no trail). 4. MATE panels work fine. 5. No issue on laptop screen and HDMI monitor. I tried re-plug, but it's still the same. Above issues can be resolved by logout-login, but it defeats the purpose of suspend though (i.e. resume opened programs). Edit: seems like incompatibility issue with Compiz (as other also experience). The screen returns normal once I terminate compiz. Issue comes back when compiz is relaunched. To use compiz, I need to logout-login. Edit: Found this comment, Quote:
Edit: Instead of logout-login, I resolve it by disable and re-enable the monitor through Displays settings (mate-display-properties). Edit: Same issue on v4.4 in Ubuntu 18.10. Last edited by vdoo; 02-21-2019 at 01:03 AM. Reason: not resolved after upgrade |
