If the memory that temporarily renders to the screen is as isolated from other 
appvms as expected rendered content (like an open windows), then, yes, I'm not 
concerned about leakage from one environment to another. 

I will say that it is simply disconcerting to see it display, security 
implications aside. More important to me, though, is the hope that this "screen 
saver" triggering will go away on future updates. Let me know if there is 
anything I can do to help that process.

This is concerning from the perspective of one who expects a lock
screen to protect the confidentiality of your activities from
untrusted people who may temporarily have limited access to your
machine while it is locked.

But perhaps more seriously, if I understand the report correctly, this
also suggests to me the potential existence of some code path which
renders stale content from untrusted appvms in a full-screen
undecorated context? If that is true, and if it is reliably
triggerable from an appvm, then this would be a useful tool for one
attempting to trick a user with fake UI. This is purely theoretical,
and standard mitigations apply as normal (e.g. trusted window-manager
actions to differentiate true windows) but this still does cause some
concern.

 I've got 16GB myself. It's not that the memory is full, but it seems to 
 happen more when I have a lot of VMs open in one desktop. That may just be 
 a coincidence though.

 I'm glad to see it wasn't just me though. I never had this happen with 
 earlier versions of Qubes on the same hardware. Not sure if it might be 
 the XFCE or a video driver issue. (I've never installed the nVidia 
 drivers.)

I don't think that should necessarily be disconcerting. The Qubes security 
model does not include or rely upon purging memory at any particular time 
interval. It assumes that you, the authentic single user, should be the only 
one with access to dom0's screen content. So, the fact that you're allowed to 
see your screen content from yesterday doesn't constitute any violation of the 
security model. You're still the same trusted user as you were yesterday. (If 
I've misunderstood your concern, please let me know.)

Sorry for the delay in responding. I used the default install for 3.2.

I also just noticed that it appears that memory is not being purged when apps 
are closed. Today when I "woke up" the screen from one of these odd screen 
saver like issues, it very briefly displayed a browser window with a site I was 
on yesterday. I looked carefully and confirmed that I did not actually have 
that window open on my system. It's as if something from yesterday's memory was 
sent to the screen and then closed. Rather disconcerting.

 I've got 16GB myself. It's not that the memory is full, but it seems to 
 happen more when I have a lot of VMs open in one desktop. That may just be 
 a coincidence though.

 I'm glad to see it wasn't just me though. I never had this happen with 
 earlier versions of Qubes on the same hardware. Not sure if it might be 
 the XFCE or a video driver issue. (I've never installed the nVidia 
 drivers.)

Yeah. I had the same thing happen when I upgraded to R3.2 as well. I
asked the same thing but nobody replied.
https://groups.google.com/forum/#!topic/qubes-users/xjHi2TcYBAQ

It still happens from time to time. Seems to happen less if I have a 
lot
of free memory. Closing down some memory hungry AppVMs seems to 
lessen

it, but I haven't been able to specifically replicate it.


Interesting, because I think I have more than enough memory (32 GB). 
Thanks.

I used the default install parameters of R3.2. xfce4-about in dom0 shows 
I'm using version 4.12. The same hardware since R2 has not experienced

[qubes-users] XScreenSaver for dom0 pops up

2016-10-26 Thread John Maher 
I'm getting the strangest thing on my screen. I'll be working and the 
XScreenSaver dialog pops up (indicating the screen is locked) and the screen 
goes black. However, the screen is not locked. I have to move a window around 
to redraw my screen. This has always happened since I started using Qubes about 
3 weeks ago. There appears to be no pattern that prompts this response. 
Bizarre! Any thoughts?
