Re: [qubes-users] Re: Does qubes block usb on thunderbolt port?
I find the thunderbolt/usb-c hardware compatibility a mess[1] The USB-C dock I have uses DisplayLink[2] for output its a pain to get to work with Linux and ~impossible on cubes without compromising security of Dom-0[3] As far as I know Thunderbolt Docks use DisplayPort pass-through so should just work assuming the thunderbolt port your using supports the feature (it may need to be enabled in the bios), though I haven’t used any of these so nit sure. [1] USB (various versions), PCIe, DisplayPort and PowerDelivery all can use the same physical plug, and it’s very much not obvious which subset happens to work on any given port. [2] proprietary compressed frame buffer over high bandwidth USB, or apparently also (wireless) network. [3] you need to attach the ports usb controller directly to Dom-0, and then recompile + install the binary blob Display Link driver see https://github.com/displaylink-rpm/displaylink-rpm , and then significant massaging of the Xorg configuration to get it to play nice.

Re: [qubes-users] How to install DisplayLink USB to HDMI converter
hi, I got this working on my laptop (dual 4K monitors), but It’s complicated, and compromised the security of dom0 (if that’s okay for you depends on your reasons for using Qubes) I’ve sketched out the steps i took below, these intentionally are not step by step instructions. It’s fragile and you will probably have to do some debugging... - ensure that the USB3 controller that you plug the display link adapter into is attached to Dom0 and not Sys-USB (I had to completely disable my sys-usb wich breaks other stuff). This opens up a huge attack surface on Dom0. Only do this if you trust all the USB devices you’ll be plugging in... - I needed to rebuild and install the display link and evdi RPMs. I grabbed the latest src.rpm got each and then rpmbuild in Dom0 to get installable packages (installing all the build and install dependencies with Qubes-Dom0-update). This is a terrible idea, I should have used mock in a domU to build the RPMs... it’s also not ideal to be installing an untrusted binary blob (display link) in dom0 - (probably related to driving 16billion pixels...) I regularly have to restart X before I can use the extra screens (stop all vms, remove the X shared memory file, restart X, setup the extra screens, start the VMs as needed) It’s probably possible to do this in a cleaner way, run display link in the sys-usb qube and share the EVDI virtual frame buffer devices between Dom0 and Sys-USB, but the later part is probably hard to get working reliably...

Re: [qubes-users] Re: I passedthrough GPU pci to win7 but can't install driver on windows
I think Nvidia have logic in the (consumer) driver to detect when it’s running under XEN (and other hypervisors) and will refuse to load/install in that environment. https://wiki.xen.org/wiki/Xen_VGA_Passthrough_Tested_Adapters Sent from my iPhone >> On 10 Jan 2020, at 05:15, xyzo wrote: > > -- > You received this message because you are subscribed to the Google Groups > "qubes-users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to qubes-users+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/qubes-users/fe3f992a-4749-4090-baaf-b3de26a55fb7%40googlegroups.com. > -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] ThinkPad T480
I have a T480 with the i7-8550 and 32gb ram. It’s a nice and powerful laptop. Everything I have used so for has worked out of the box for, except power management. I have the large auxiliary battery (advertised 27hrs, and I got that running windows) with gives me about 3-4 hours running wines (which is ok). I haven’t yet figured out of to fix the power management, so it runs hot and has the poor battery life.
