Comment 9 for bug 1971149

This maybe unrelated but I'll write it here too:

Since 22.04 the mouse movement on my external monitor feels laggy, jerky, while on the internal display it feels ok. I think on Ubuntu 20.04 there was not such an issue. I use Windows (same configuration) and macOS too with this monitor and they are smooth.

After performing the above sleep experiment I think the mouse movement got smoother. Now only my external monitor is turned on.
