Sorry, that was phrased wrong, and I hate to add any confusion for anyone.
 (I really should read more carefully before posting.)

I see the updated packages are for qubes-gui-agent's in the fedora/debian
templates.  Will grab those, fire up several AppVM's, and see if things
improve.

Cheers.

This might explain why I didn't see this behavior, because the external
USB drive that I booted 3.2rc1 from was a USB3 drive that internally
used RAID0, so it's probably faster than most.  Might I ask whether your
external USB drive was USB2 or USB3, whether it was an HDD or SSD, and
whether it used RAID0?

Sweet!

Mainly looking to have Keepass, running in an offline AppVM, to be able to
fire up specifically-allowed URL's in a browser in another AppVM, and
stuff a password into its clipboard.

(So it sounds like I could restrict the qrexec to a custom script in the
AppVM that only opens that specific site; and stuffing the clipboard
should be pretty benign, too.)

If I'm very careful about the permissions, I should be able to keep any
risk under control.  The qrexec design looks pretty flexible.

Thanks!

Hello,
Here is the HCL report for the HP Envy 14 LR1281G4W
Qubes 3.1 gave me "warm black" after install and was unable to boot so I 
installed Qubes 3.2 RC2 and the OS will now boot.

Upon boot i receive the error "Failed to start Load Kernel Modules" 

once logged in i am unable to connect to the internet or even scan for networks 
with my wireless receiver.

also there is no application bar. it never loads or shows up. any suggestions? 

Thank you,

I think you're normally supposed to set the desired resolution from within the
HVM OS's internal settings. In this case, try to set the desired resolution
within CentOS.

I think it's to be expected that attempting to force window properties in
KDE's window settings wouldn't work, since CentOS doesn't "know" about dom0's
window manager.

A tip for moving unwieldy windows around: Since you're using KDE, you can
simply hold alt, then drag anywhere on the window. This should work even if
the title bar is completely offscreen.

This issue has been reported previously:

https://github.com/QubesOS/qubes-issues/issues/2246

As you can see from the comment, the other user's media check also failed
after 4.8%. However, copying the same ISO onto a different flash drive (8 GB
Kingston) from a different computer (Linux Mint 17.1) worked. Perhaps you
could also try an alternative flash drive and/or computer?

If it still doesn't work for you, we can reopen the issue.

Yes, but it's completely user-configurable. You can read all about this system
here:

https://www.qubes-os.org/doc/qrexec3/

Pay special attention to the section titled "Qubes RPC administration." As
that section explains, there's a file where you can enable using qvm-run from
within an AppVM. That file is:

/etc/qubes-rpc/policy/qubes.VMShell

However, before doing this, there is a very serious warning that you should
heed:

Yes. The action is prohibited by default because it can be so dangerous.
However, as explained above, advanced users can choose to selectively allow it
for certain VMs at their own discretion.

Just a shot in the dark:

In order for IOMMU to work, it has to be supported by the CPU, chipset, and
motherboard. According to this previous guide, a common problem faced by many
users looking for compatible hardware is that even though their CPU supports
VT-d/IOMMU, their chipset does not:

https://groups.google.com/d/topic/qubes-users/Sz0Nuhi4N0o/discussion

Is it possible that, even though your CPU supports IOMMU, your chipset does not?

IIRC, some users have even found that their motherboard does not properly
support VT-d/IOMMU, despite the option to enable it being available in the BIOS.

I don't know enough about the AMD platform to answer definitively, but if I'm
interpreting this Twitter exchange correctly, it sounds like you might be right:

I'm not sure, but my guess is that it should largely the same as Fedora, the
difference being where you make the changes (dom0, sys-firewall, or sys-net).

[qubes-users] Installation boot problems on Lenovo T420

2016-08-19 Thread cedarrabbit
Hi everyone (Sorry if this is a double post, my post from a few hours ago
didn't seem to go through)

Would-be new user of Qubes here, but a longtime Linux user. I'm trying to
install Qubes-R3.1-x86_64 on a Lenovo Thinkpad T420. I encountered the
"hangs on penguins" problem described here:

https://www.qubes-os.org/doc/uefi-troubleshooting/

I followed the steps there and they all worked well, until the very last
section where it asks for " /boot/efi partition number". I don't know what
that is and I don't think it came from the previous steps. I tried it with
the entry number and with a similar number that came up during a different
step, but neither worked.

One time it gave me an error reading "segmentation fault" and something
about needing a unique instance. When I rebooted, I couldn't boot to
anything. Another time it created two instances of Qubes in the boot menu
but trying to boot to either got stuck at penguins.

I think all I really need is to know what a partition number is and where
to find it. Googling hasn't helped me so far, and I'd really appreciate
any help you all could provide.

Thanks so much for all your work!! Looking forward to getting Qubes going.

Re: [qubes-users] Re: installing Signal on Qubes mini-HOWTO

2016-08-19 Thread RSS

> Is F-Droid's Silence any better than Signal given it can run without
> Google Play Store?

I use CyanogenMod Android minus most of the Google malware (ie. no
Google play). In that configuration Signal refuses to work because it
(at least) depends on Google Play for notifications. Silence however
does not, and works great. On Android, with a sim card.

However, it is my (not deeply researched!!) understanding that the
Signal dev(s) do not like/permit other applications connecting to their
servers. No servers, no direct messages, all Silence messages are
necessarily SMS messages going over the phone network. So Silence will
not work outside of a phone with a working sim card.

I was just about to post the same problem, I'm guessing I have to pass a device 
to the vm I'm just unsure which one. I had my headphones plugged in when I 
started audacious in one of my vms I got this error message:

ALSA error: No suitable mixer element found.

ALSA error: snd_mixer_attach failed: No such file or directory.

when trying to play some of the songs I got this:

ALSA error: No suitable mixer element found.

ALSA error: snd_mixer_attach failed: No such file or directory.

ALSA error: snd_pcm_open failed: No such file or directory.

I'm updating my VM's and rebooting to see if it helps.

[qubes-users] HVMs auto-resizing, causing positioning issues.

2016-08-19 Thread Joe Thielen
I have a minor GUI usability issue.

I'm using a smaller monitor, and my CentOS 7 HVMs seem to always want to
take up the entire height of the screen.  The problem is the HVM window
title bar will show at the top cutting off a little at the bottom of the
window.  When using text-mode/CLI, this means once I get to the bottom of
the screen I can't see what I'm typing.

I've tried right-clicking on the title bar, going to More Actions, then
Special Window Settings.  If I set Position to Force 0,-25, this seems to
work when I do it manually.

When the HVM boots again it works... for the first bootloader screen.
However, after that, the HVM re-sizes itself, and I'm in the same boat
again.  Now, when I go back to look at the settings, it still says Force
0,-25, and if I hit OK, it will resize.

The problem is it doesn't do this automatically upon resizing.

I could force position to 0,0 then remove the header and frame.  But then I
can't figure out how to get the header back, in order to get to the
"Special Windows Settings" menu section again... in case I want to make
further changes.  If I right-click on the HVM in the taskbar there is a
"More Actions" section, but no "Special Windows Settings".  I can only seem
to find it when right-clicking the title bar.  But I've removed the title
bar for this HVM now...!

Any ideas?

I think I have a problem with the sound on my Qubes-OS 3.2rc2. Sound 
works fine with the speaker, but as soon I plug in headphones I can't 
hear anything. I can see the that the sound is playing in the Volumen 
Control but I can't hear anything. Also, it the Volumen Control shows 
that the headphones are plugged in. Anybody with the same problem or is 
it maybe a Layer 8 problem ;)

[qubes-users] 3.2RC1 fresh install, no internet access on sys-net

2016-08-19 Thread Jeff Gagnon
Hi, i did install a fresh copy of 3.2RC2 on a HP DL360 G6. when sys-net start, 
i can see icon on the top (dom0) saying Connection established, but there is no 
network access. 

my dhcp server provide ip address to Qubes, i can see it with ifconfig on 
sys-net, but i can't ping other device on the network from sys-net terminal. 
Also, from the cisco switch or from the dhcp server, i can't ping the address 
provided to qubes. 

i downgraded to 3.1 to check, and the problem remain. 
I did install VMware Esxi 6.0, and everything is fine with network. 

here is the /etc/resolv.conf of sys-net

[user@sys-net ~]$ cat /etc/resolv.conf
# Generated by NetworkManager
search jefflinux.com
nameserver 10.195.198.2

this is my domain and my dhcp/dns server ip address

I did try to set it to static (with dns and gateway) using the red network icon 
in the dom0 menu bar, but still no success. can't ping from each side.

here is the log from my dhcp server: 

Aug 19 11:28:33 pingouin dnsmasq-dhcp[24241]: DHCPDISCOVER(enp10s0) 
f4:ce:46:85:0b:70

on sys-firewall, the resolv.conf only have 10.137.1.1 and .254, which is 
normal...

Thanks

I am very new to systemd, but I believe the cause of my corruption is that
there may be a typo bug in one of the directives for systemd's
umount.target.

"systemctl show umount.target" reveals:

> JobTimeoutUSec=0

"man systemd.directives" and "man system.unit" do not show any such
directive; however, they do show "JobTimeoutSec" which I believe was
likely the intended directive, and which would set no limit on waiting for
that shutdown filesystem unmount, and I believe would prevent the
corruption I was seeing.

A zgrep of all the man pages shows no indication of JobTimeoutUSec being a
legit property.

Cheers.

It looks as though this thread went nowhere. I'm having the same problem as the 
original poster above. I've tried creating an install USB with both Windows and 
Linux - same result. 

I'm happy to try editing the edit kernel command line, but am hoping someone 
has solved this before I proceed. Please let me know if this problem wasn't 
solved.

Thanks,
Mike

[qubes-users] Clipboard

2016-08-19 Thread johnyjukya
Is there any qvm-* command, or other method, to programmatically copy to
the qubes clipboard?

(Similar to my last question, a perfectly reasonable answer might be "of
course not, are you crazy?" due to security concerns.  Requiring explicit
dom0/GUI user interaction for clipboard manipulation seems like a good
idea, but I thought I'd ask anyway.)

Thanks.

JJ

[qubes-users] qvm-run only available from dom0?

2016-08-19 Thread johnyjukya
When I try to run qvm-run from within an AppVM, I get "Request refused."

Is this by design, for security reasons?  If so, I guess that's perfectly
reasonable.  I just don't see that fact documented anywhere.

(The demonstration of one of the Xen exploits executes a qvm-run of xcalc
in dom0 from an compromised AppVM, which kind of implies the fact that
such behaviour is normally restricted between AppVM's.  If this is indeed
the case, it might be useful if certain commands could be configurably
whitelisted, from a config file in dom0, to be qvm-run between specific
VM's.)

Thanks.

Re: [qubes-users] Screen corruption on nvidia

2016-08-19 Thread johnyjukya
 However, under Qubes, I experience random screen corruption.

Actually, just FYI, the behavior seems to be a lot better under 3.2rc2. 
I've only seen it a couple of times, versus seeing it consistently under
3.1.

[qubes-users] Qubes OS installation freezes at installing bootloader?!

2016-08-19 Thread Darko Vuković
Hi there,

does anyone have any idea on how to continue after thin problem?

somewhere in the middle of the installation process screen freezes exactly at 
the moment where installer says "installing bootloader". Every time!

If anyone have some solution to this, please share!

Thanks in advance.
