Hi everyone, I'm trying this tool on an Olivetti OlivoBook P1500 with Sis Mirage 3 and Zorin OS 17, but I can't make it work, at the end of the procedure the message "Please reboot your system now" appears, I restart the PC but nothing changes, does anyone know how to help me?

Oh, forgot about this.

If you have the same graphics device, the final solution for me was not to use this repo's driver, but to tell X to use the VESA driver.
For that, in the Xorg config file, in the Device section, I have repalced the value of the Driver setting with vesa. After a reboot (maybe even a relogin) it should work.

I have found this solution on the Mint forum: https://forums.linuxmint.com/viewtopic.php?t=266554
