Thinkpad T440s i7 and Qubes 4.0 compatibility

[Eivind K. Dovik]

Hi,

I have been offered a great deal on a used Lenovo Thinkpad T440s
(secondhand, but I trust the current owner). I am currently on a Macbook
Air running Debian and would like to make the switch to Thinkpad and
Qubes.

Does anyone have experience running Qubes 4.0 on a T440s? The T440s I am being offered has
a 512gb ssd and an i7 CPU.


Best,
Eivind

I run Qubes 4.0 on T440p and it runs great. 500gb hdd and an i5 vPro CPU

I went and got the T440s today. I had prepared two USB drives: one with
Qubes 3.2 and another with Qubes 4.0. I tried installing Qubes 4.0 first. After setting
boot to UEFI, I was able to install Qubes 4.0. After installing, I ran
into problems when booting - ended up in a boot loop, never getting to the
grub-screen (this occured no matter what boot settings I set in the BIOS).

After playing around with the different boot settings, I tried installing
Qubes 3.2. This time, I had to do Legacy boot to get to the installer.
Installing was a breeze, and I'm currently running Qubes 3.2. Wouldn't
mind upgrading to 4.0. If anyone has a solution to my
boot-loop-problem, I'd be thankful.

maybe, I am missing something, did you try installing 4.0 in legacy mode?

it seems with the older thinkpads this is the way to avoid the dreaded
black screen EFI thing.

I tried installing Qubes 4.0 in legacy mode at first. I was presented with
the legacy-installer, and after hitting "Return" the screen went black.
UEFI-installer worked like charm, but booting after install did not (stuck
in boot-loop, no grub-menu).

I'm using a Thinkpad w530 and I had to play a little bit with BIOS settings, since virtualization does not play well with graphic card.

So I had to enable virtualization in BIOS (it's disabled by default) and then use integrated graphics (if no external monitor is connected) or optimus (if I have a external monitor).

After finding the right combination of these settings, I could boot without issues.

Hope this helps.

I noticed on the HCL that some TPad users had to change the Bios
graphics as well, My 530 didn't have that setting , "discrete graphics"
