Hi, older Toshiba laptop new SSD & 32GB Ram (upgraded by me) running Fedora 40 KDE.
Tried all the options when trying to install including the last one (latest kernel) even added nomodeset=0 to the line & CTRL + X but still just get grey screen with still white line, top left corner. And secure boot NOT enabled, have tried all the options, (waiting with baited breath for 5 mins each time) inc test media, to no avail (no cursor movement nothing). Please advise 
Your CPU doesn’t have VT-d support that is required for Qubes OS:
- Intel® Virtualization Technology for Directed I/O (VT-d) ‡ No
Bummer!
