Hi,

I just completed a fresh R3.2 install on a Lenovo X1 Carbon 3rd generation (20BSCT01WW). Thanks to all the devs for their amazing work on this release. So far as I can tell, everything works out of the box. (One of my favorite features is the ease of implementing VM-by-VM VPNs.)

I want to enable TRIM for the SSD, following https://www.qubes-os.org/doc/disk-trim/. However, there is no /etc/default/grub in dom0. I realized that grub2-tools is supposed to provide /etc/default/grub and grub2-mkconfig. So I installed that in dom0. But there is still nothing in /etc/default/grub. Where can I find the default /etc/default/grub file?

Thanks for any help you might be able to provide, I hope to pass it on in the future to other users.

Best,
Daniel

I guess you have installed the system in UEFI mode. In that case, kernel
parameters are in /boot/efi/EFI/qubes/xen.cfg.

Hi Marek,

Thank you for the quick response. That hint and a bit more searching helped me find this earlier discussion on the mailing list: https://groups.google.com/forum/#!msg/qubes-users/KTRlrc9vC1U/ajxXQtBPBAAJ

Editing xen.cfg and then relocating the initramfs produced by dracut solved the problem. Perhaps someone with permission could add a link to that discussion to the wiki page.
