Qubes on Lenovo Thinkpad X250 Issues

[rayho...@gmail.com]

I have attempted to install Qubes OS on my Lenovo Thinkpad X250 in "Legacy Mode". The installation itself works without incident, but when I attempt to boot, things hang on a black screen with a blinking cursor. I have also attempted to install in UEFI mode, but in that case the installation process does not even create an EFI entry (and I abandoned UEFI after reading about other peoples' troubles).

I have never read about anyone having trouble installing Qubes in Legacy mode, is there something that I'm forgetting? I have turned on Vt-d and Vt-x in the BIOS, but I don't imagine that forgetting this would prevent the system from booting.

It looks like others have reported a similar issue here:

https://groups.google.com/d/topic/qubes-users/fRxncIsQrGc/discussion

However, the report says that the booting issue only happens
sometimes. Are you unable to boot at all, even after multiple attempts?

Just to confirm: Are you on Qubes R3.1 (stable)? Have you tried
installing any other releases?

Even after trying to boot numerous times it never manages to. Yes, it is Qubes R3.1. I will try other releases later today.

5th generation

Qubes 3.0 appears to work perfectly, so I'm happy for now. Don't know why this issue was introduced between 3.0 and 3.1.

[Thierry Laurion]

Bump. Its not Qubes specific. Same applies to latest Xen Hypervisor on Ubuntu 16.04.1.

Any idea what got introduced into Xen between 3.0 and 3.1?

There was a change from Xen 4.4 to Xen 4.6 there. So, probably a lot of
changes...

I am using a X250 since last february (installed R3, updated to R3.1 and full reinstall of R3.2).

No problems with booting so far.
Let me know if you want to compare BIOS versions, config, etc.

Regards,
///Pablo

[Thierry Laurion]

Yep I would like to, as I was able to use 3.1 with Legacy but can't boot 3.2.
Updated BIOS to 1.25, made sur vt-d and vt-x were activated.

It's an i7, if it changes anything. Attempting to add Xen hypervisor to Ubuntu results in the same behavior. Will attemtpt to find debugging arguments and setup AMT to have debug logs.

Did you manage to troubleshoot? I would like to reinstall Qubes v4 on my X250, after having given up due to booting problems at v3.1, and the issue is not identical, but might be connected.

Installation succeeds, but when booting just some lines mentioning xen are visible and then a black screen appears. No grub, just a black screen, and I can't find a way of interacting with the computer to debug.

Maybe someone has had similar issues and knows how to solve them?
Thank you.
