I've run into an issue where mine doesn't even maintain connection for some 
reason (I haven't had the time to diagnose it) It connects and then disconnects 
from sys-net. 

It also does the same for any netvm that I try and connect it to.

Re: [qubes-users] Apps not starting on the first try

This seems to be a new issue on a recent reboot.

If I try to run a program from a VM that's not yet running, the VM
starts as expected, but the program never runs. Even after the VM is up
and running, I can't get any program to run in that VM. Even opening a
window in dom0 and using the qvm-run command does nothing.

However, if I kill the VM, the next time I try to run a program (which
reopens the VM), it works perfectly.

Any thoughts on troubleshooting this?

Thanks.


This is a long-term issue and the reports usually center around nautilus 
(Files) because that it the most prone to the behavior.


See https://github.com/QubesOS/qubes-issues/issues/2449

I believe its caused by gnome expecting some session-related daemon to 
be already running when it tries to start a program.

I've investigated it further, found a crazy hack (with some drawbacks) and

My investigation briefly: Fedora 23 (live distribution, no updates) has the

control brightness). Fedora 25 (live distribution, no updates) has those issues 
fixed. I guess, Qubes 4 will work fine out of box on this laptop.

The crazy hack is: take the kernel from Fedora 25 and use it in Qubes. 
Theoretically, PV support is in Fedora out of box for a long while (see 
https://wiki.xen.org/wiki/Fedora_Host_Installation ), so it should work.



Wish I noticed this earlier... There is a newer kernel v4.8.12 in 
"unstable" repo and it works very well.

Re: [qubes-users] A way to restart VpnVM same as can reload/restart tor?

Thx, I created it uisng the Qubes Doc instructions. So perhaps I could
combine the two lines you wrote to make it a bit shorter?

alias rstopvn="sudo pkill openvpn && sudo /rw/config/rc.local"

maybe?


In this case using a ';' semicolon between the commands instead of '&&' 
makes sense, because openvpn may not be already running.


BTW, another thing you could do instead is to add an infinite loop to 
the end of rc.local:


while true; do
sg qvpn -c "$VPN_CLIENT $VPN_OPTIONS"
done

Yet another thing you can try (because I'm recalling my early 
experiences with openvpn) is to comment-out the "persist tun" line in 
your ovpn file. Openvpn can experience problems trying to re-use tun 
devices, and that can cause it to quit when trying to re-connect. This 
is the simplest remedy.

[qubes-users] Re: Windows hanging at starting up screen (changing xen video -> cirrus not working?)

[Gaiko Kyofusho]

No responses? Is there any more information that I could post that might
make it easier to diagnose this issue?

For what its worth, I was able to make a non-template winVM on another
computer (before I quite understood that I could make a WinTemplate) and
then restored it onto my current computer and it works well enough, but I
really think the best model for me would be using a wintemplate if
possible, and was hoping to figure out why the intstalling win7 on this
win7-x64-template isn't working?

Thoughts would be apprecaited.

Hi, yes I may have not used vi right, but think I have it now (google is my 
friend):)  

As mentioned earlier, I can't interpret the next steps in Eva's post and had 
some specific questions.

Thanks,
Patrick

Re: [qubes-users] [3.2] Issues with Intel® HD Graphics 620 after update of clean installation

[Vít Šesták]

OK, I've found how to compile it 
https://groups.google.com/forum/#!topic/qubes-users/yBeUJPwKwHM/discussion .

Now, I am running on a compiled kernel with the Qubes-related patches. It works 
mostly the same (supend/resume OK, graphic output OK and using i915, brightness 
works, OpenGL via llvmpipe, sys-net issues I mentioned earlier). Well, 
qubes-dom0-update works better now, because it does not want to remove the 
kernel I am currently using…

The sys-net issues after resume are easy to resolve: rmmod and then modprobe 
iwlvmv+iwlwifi. This seems to be minimal set of modules you need to refresh via 
rmmod+modprobe.

So, it works now. With Qubes 4, it will probably work more out-of-box…

Regards,
Vít Šesták 'v6ak'

There's a link in the last section. If you need to create a *.desktop

vim (the texteditor someone tricked you into using earlier) leaves these
if you don't exit it correctly. You can safely delete these files. Until
you learn to use vim properly, maybe try nano instead. (vim is great,

This question is very frequently asked. Perhaps we should change "in the

[qubes-users] No network connection v2

[menthols]

Today installed Qubes 3rd release, but no network connection. Spent hours 
trying to fix it, but to no avail. Network card is recognized. I have two 
cables connected, no WiFi. I try to put qubes on Dell poweredge, Intel Xeon e3, 
8 GB RAM, Broadcom NetXtreme Gigabit Ethernet PCIe, two 1 TB harddrives. I used 
option "Test and install" at installation, no error message. I have choosed 
both harddisks at install, hope there is someway to configure the soft raid. 
Before tried to install other Linux flavors before (Debian-8 and Fedora-23) and 
none of them had any trouble connecting to the internet immediately (updates 
downloaded during install). Maybe need to activate some more PCI devices. 
What's the best I can do? Wait for the next release? Buy another machine? ;-)


Opened netvm terminal and checked the following things: 

1. Does 'lspci' list your network adapter?  
Yes, i've tried both debian-8 and fedora-23 both list the network cards.

2. Do you have interface detected (does 'ifconfig -a' contains en* device)? 
No, none of them detect the interface using ifconfig.

3. Does kernel messages ('dmesg') contains some errors regarding network 
device initialization? 
No, there is no message regarding network at all.

4. Check if linux-firmware package is installed (rpm -q linux-firmware).
Yes it is installed.

Normally we push updates to stable repo 7 days after uploading to
testing (or more if update is bigger or potentially more problematic -
but it isn't the case here).

[qubes-users] Apps not starting on the first try

[Todd Lasman]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

This seems to be a new issue on a recent reboot.

If I try to run a program from a VM that's not yet running, the VM
starts as expected, but the program never runs. Even after the VM is up
and running, I can't get any program to run in that VM. Even opening a
window in dom0 and using the qvm-run command does nothing.

However, if I kill the VM, the next time I try to run a program (which
reopens the VM), it works perfectly.

Any thoughts on troubleshooting this?

Thanks.

You could try re-installing thunderbird




apt-get purge thunderbird icedove

apt-get install thunderbird

I started a thread about this back in April.  Apparently a known issue with a

By chance are you logging into the same Google Account in the different VMs?  I 
have noticed this same behavior, but only when logged into the same Google 
account. In fact, many times something causes the session to disassociate with 
the browser and hang - I suspect there's something in the network part of the 
hypervisor that is causing google to get confused as to which VM should be 
authorized, etc - as the same IP is being used. Or, something in this regard.

If I close out of the Google Sessions each VM seems to work fine - but, when 
this does happen it surely causes the VM to hang up for a very long time.

Not wanting to push it too much but is there a rough eta as to when these 
patches will be pushed to 3.2-stable?

Seeing same problem here. I think it is a known issue [1] related to some 
recent updates. I don't use chromium either, but there is a related issue for 
that too [2].

[qubes-users] debian8's thunderbird dead

[Bernhard]

Hello,

since debian-8 rebraded icedove thunderbird, they are all dead. On the
command line the just spill out "Killed" verbose or safe-mode give no
better information. This may or may not be linked to the change in
debian8 - it may also be linked to the "immutable script" in rc.local
that I copied after some hardening discussion here in the forum 2 months
ago. I don't see how, but since I am lost I look for any possibility.
May you help me?  Thx, Bernhard
