[qubes-users] troubleshooting Iris Xe problems


I’m currently trying to troubleshoot my Iris Xe graphic card problems by following this guide:
It advises to modify: Edit /boot/efi/EFI/qubes/xen.cfg (e.g. sudo nano /boot/efi/EFI/qubes/xen.cfg) Unfortunately, in my latest v4.1 beta installation with EFI there is no such file. Only files in /boot/efi/EFI/qubes are: fonts grub.cfg grubx63.efi xen-4.14.2.efi None of the seems suitable. Any ideas? Best, P.
