[qubes-users] will it work with ultrabook?

2022-01-24 Thread Anna Kovalchuk
Hi guys. I want to buy a laptop to work with this operating system. I found 
this one for myself, with the maximum configuration. will it work well? who 
knows? any advice with which device better to work? 


https://www.qubes-os.org/hcl/#hardware-laptops

Unfortunately, I would like new models to be released in 2021 ... otherwise 
all the options offered there are already an excellent pillow for the 
homeless in a landfill... maybe there is something for a person who earns 
more than 300 bucks per month??? I didn’t find it on this list... 
Can you recommend a laptop newer and faster than my grandma?

[qubes-users] Keep hard disk mounted when PC goes into suspend mode

2022-01-24 Thread Michael Singer

Dear Qubes community,

I am trying to permanently mount a hard drive in such a way that it will not be 
removed when I put the computer into suspend mode. Unfortunately, it does not 
work when I do the following:

1) dom0: qvm-usb attach --persistent example-VM sys-usb:3-3

2) Open Nautilus in the example-VM and mount the harddisk.

3) Put the PC into suspend mode.

When the PC wakes up again, the hard disk is no longer accessible as 
sys-usb:3-3, but suddenly as sys-usb:5-3. Accordingly, the Nautilus window no 
longer shows the folders on the hard disk and the hard disk has disappeared 
from the Qube. If you then mount the hard disk again in the example VM and put 
the PC into suspend mode and wake it up again, then it remains with 
sys-usb:5-3. The hard disk is then still assigned to the example VM, but is no 
longer mounted there. Accordingly, it is again the case that Nautilus displays 
an empty window.

I have experienced this with Qubes 4.0 and Gnome Debian. Does anyone have an 
idea how to set it up so that the hard disk is still mounted after suspend mode?

It looks like it is some weird fedora34 compatibility thing,
and not the qubes scripts that was causing my problem.

What worked for me was adding the following two lines to
my /rw/config/qubes-firewall-user-script

> # For some reason a duplicate nftables ruleset is getting created
> # that mirrors the iptables ruleset.  Flush it so that only iptables

> iptables -I FORWARD 2 -s 10.137.0.13 -d 10.137.0.33 -j ACCEPT

In particular "nft flush ruleset" was needed before any iptables changes
were reflected in the forwarding behavior.

What is the appropriate way to get https://www.qubes-os.org/doc/firewall
updated to reflect that people my have to deal with this?

Eric

[qubes-users] Re: Google Maps producing a very high CPU usage

In Qubes the graphics card hardware acceleration is not exposed to the vms 
for security reasons 
(https://www.qubes-os.org/faq/#can-i-run-applications-like-games-which-require-hardware-acceleration).
So it is incorrect to blame Google for this.
