Dell XPS 9310 Linux install notes (Ubuntu/Xubuntu 20.04)

My NL i7/16GB XPS 9310 has a Killer AX1650s WiFi chip, which eventually worked. Other Killer chips may not work.

I ordered the Windows Home edition, because developer edition with Linux was not available in my country. Apparently you can reclaim €100 from Dell if you don't use Windows.

Install

• Bios:
• Change the SATA Mode from the default "RAID" to "AHCI"

Intel for display, NVIDIA for computing

This guide will show you how to use Intel graphics for rendering display and NVIDIA graphics for CUDA computing on Ubuntu 18.04 / 20.04 desktop.

I made this work on an ordinary gaming PC with two graphics devices, an Intel UHD Graphics 630 plus an NVIDIA GeForce GTX 1080 Ti. Both of them can be shown via lspci | grep VGA.

The TLS key schedule looks like this:

QUIC effectively exports the various traffic secrets, so I had assumed that its use of the different base label in HKDF-Expand-Label() would be limited to those uses that were after that export. I forgot key update when writing this up, but that was fixed in #1899.

However, in looking at what people implemented, it appears that the base label they use was used for the entirety of the TLS key schedule.

Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface.
You can use the user and password that you use for the web interface.

You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS.
You don't need to install it, just extract it or copy the files in "jre" folder.

Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor.
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture.
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs.

Save the route script to /usr/local/lib/openvpn/route on the client. Make it executable with chmod +x.

Remove the push redirect-gateway option from the OpenVPN server config.

Add these options to the OpenVPN client config:

setenv OPENVPN_ROUTE_TABLE 94
route-noexec
route-up /usr/local/lib/openvpn/route
route 0.0.0.0 128.0.0.0
