Lenovo T460: Troubles with intel graphics and network interfaces

[sacke...@gmail.com]

Hello,

I have Qubes 3.2 running on a Lenovo T460 and I am encountering 2 problems:

1.) I have a docking station with 2 monitors connected to it. When I put the notebook in the dock and enable the second screen, sometimes everything freezes a few seconds after enabling the second screen. After that I have to reboot the whole device. I found out that when i delete /home/username/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml, then reboot and then turn on the second and third screen it works sometimes...but I cant really find out why it works or fails from time to time. I found a few tipps regarding configuration of the intel i915, but it seems nothing really works (or maybe I am just too stupid for it) :)

2.) When Qubes goes into sleeping mode I loose my network devices in sys-net. This means that I dont see any Ethernet or wifi card anymore in network-manager. I have to reboot sys-net or the whole machine to see the devices again. The only workaround I can imagine is deactivating hibernation.

I would be really happy for any tipps how I can troubleshoot or fix this.

Thanks!
