My trackpad requires that I enter pci=nocrs into grub boot parameters in order to work. How do I do this in Qubes OS? In addition, is there a way that I can set this temporarily, like for a single boot only? I am a bit concerned about what might happen if I mess with pci device settings considering that there is another layer of abstraction from the hardware in Qubes. Does anyone know specifically how pci=nocrs would affect Qubes? I know it works with other linux distros.
You don't have to answer all of my questions. Any help will be appreciated.
I see a xen.cfg file in /boot/efi/EFI/qubes that appears to have boot parameters. Do I just tag pci=nocrs onto the end of the 'options=' line?
