Hello Qubes users
Does anyone have an AMD based laptop that doesn't have PSP (i.e. anything
pre-2013), and if so, does it work with Qubes 4? Mainly asking for hardware
recommendation and so that I can choose a stock model that does come with a
working AMD-V with RVI and AMD-Vi (aka AMD IOMMU).
Thanks infinitely for any help!
Boom.
Lenovo G505S.
https://www.coreboot.org/Board:lenovo/g505s
Owner controlled.
The blobs for video and power management are removable as there isn't
any hardware code signing enforcement.
Some thoughts:
- A10-5750M is 2013 Q2, the request is pre-2013. For this chip, does it have
the privacy invasive blob? or is it without?
It doesn't have PSP.
- The A10-5750M isn't all that fast, but it isn't super slow either for normal
requiring needs, like browsing, streaming, writing, in Qubes.
I use a CPU which is much slower than that and I don't have an issue.
- 6GB RAM is harsh for Qubes, while it may work with few VM's up, it can be a
hassle. Need to ensure that the machine can upgrade its RAM, but it should also
be considered an extra expense before buying. Never mind checking whether it
can be upgraded or not to begin with. Is the RAM easily accessible? Does the
current RAM have to be removed or does it have an extra free slot? etc.
Of course you can easily upgrade the RAM.
- I would also consider a HDD to be less optimal for Qubes. I haven't run Qubes
on non SSD's, so I can't be entirely sure, but it strikes me as more different
than between Linux/Windows running on HDD vs. SSD, due to all the loading and
copying during Qubes runtime. While HDD seems entirely practical and feasible,
it does also seems like it might cause some buttlenecks, which may not be
desired. There is also a question of how big these bottlenecks actually are.
Anyone have experience with Qubes on HDD's vs. SSD's here? If wanting an SSD,
it'll be an extra expense in addition to the RAM, unless you have an unused SSD
laying around already.
You gotta have an SSD, but used laptops don't come with drives so you
would be buying one anyway.
- Is the firmware blob really removable and truly user controlled? You hear a
lot of claims like these, but I haven't actually seen anyone completely succeed
yet on any decent laptops.
Yeah this is the real thing-- it isn't like purism's faux free firmware
where 100% of the init process is done via binary blobs.
The only blobs are for video and power management, so this is the best
option there is - in comparison the Lenovo X230 with coreboot will have
an open source init for those but you'll be stuck with a nerfed ME - in
my expert opinion the G505S is the better choice.
Trust me, I have 4 computers that run coreboot and I am a regular on the
mailinglist.
- Lenovo is known to be a customer- and privacy offender, as well as a proven
lier in these regards, caught with their hands in the candy jar, multiple of
times again and again at that. What reasons are there for this Lenovo laptop to
be exploitable to the point, that it makes up for the bad and distrust rep of
Lenovo? Can everything Lenovo can do to the laptop, really be undone?
Lenovo's shenanigans were BIOS based, if you install coreboot you
replace their BIOS.
- Has other people run Qubes 4 RC-2 on the Lenovo G505S? On paper it looks good
enough, but has anyone tested this?
It'll work, trust me.
