[qubes-users] XScreenSaver for dom0 pops up
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? Thanks. John -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

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.

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.

It assumes that you, the authentic single user, should be the only one with access to dom0's screen content.

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. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

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.
