Title:
[nvidia] Display Scaling causes monitors to sleep
Status in mutter package in Ubuntu:
New
Status in nvidia-graphics-drivers-440 package in Ubuntu:
New
Bug description:
Default install of Focal Fossa 20.04 Beta downloaded April 4, 2020.
Steps to Reproduce:
1. Open Settings
2. Navigate to Displays.
3. In Scale section, select `200%`
4. Click Apply
Expected behavior: Screens refresh with a 200% scale applied and a dialog to
confirm.
Error encountered: Screens switch to "power saving mode" (go blank). After
about 15 seconds, they wake up in the original 100% scale mode.
Other notes:
I have done this successfully with 18.04 on the exact same hardware
(different hard drive partitions) in the past after installing NVidia drivers.
I have successfully rearranged the monitors in Settings and changed the
Primary Display in Settings with this install.
