Good troubleshooting steps. That i915 is a bit dated though, so I suspect you have some other Intel video driver related issue. Further review the Xorg.0.log file prior to the line about software rendering, and see if you can locate a reason for it being unable to use hardware acceleration. There may also be clues in dom0's "sudo journalctl -b" log. PS You should have been able to edit xen.cfg using your method, but without decrypting. For future reference at least, it's located under /boot/efi/EFI/qubes. -- - don't top post Mailing list etiquette: - trim quoted reply to only relevant portions - when possible, copy and paste text instead of screenshots -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
