Screens remain blank on Mint 21 Acer Aspire R5 Intel graphics card

[tonyscardina]

I installed the debian installer from this repo.

lsusb shows the adapter and xrandr --listproviders shows multiple displays (see below) but the displays do not show up when I open the "Displays" app that comes wth Mint. The one used to configure multiple displays.

The screens do display the "Universal Graphics Adapter" message, but then stay blank and go into power saving mode.

When I remove the adapter and plug the screen into an HDMI port, it works. (I only have one HDMI port and plan on having two external screens)

When I tried the solution at #228 (comment) there was no change

When I tied the solution at #236 (comment) I lost my GUI (thankfully command line still worked so I could restore the backed up config file)

Success! This ticket can be closed.

I ended up trying the fork of this project with no luck, and then forgot to unintall before installing this driver: https://www.siliconmotion.com/downloads/SMI-USB-Display-for-Linux-v2.22.1.0.zip and now it works.

Whether or not I needed to install one over the other I don't know, but it is working now.

ENORMOUS THANKS! To ALL the people working on this project and the forks
