The command line "unison work ssh://remote.dcs.ed.ac.uk/work" fails, with "fatal error: could not connect to server." But when I connect directly with ssh remote.dcs.ed.ac.uk/work, I see that my PATH variable is correctly set, and the unison executable is found.

Logitec Camera C210 (maybe C270) - Error - lvrs64.sys , lvuvc64.sys Windows 11 memory integrity

Problem

There problem with the Logitech webcam software are the drivers lvrs64.sys and lvuvc64.sys. These drivers are blocking Windows memory integrity.

Solution

I managed to make this working removing all the drivers from Win11, and use native Win11 native drivers.

Windows+X > Device Manager> Imaging Devices > Uninstall device > remove with drivers.
Disconnect and connect camera [Error will pop up, ignore it]

Intel GPU on Win11 22H2 WSL2 Ubuntu 20.04, gcc 9.4.0

Notes of support of Intel GPU in WSL can be found here https://github.com/intel/compute-runtime/blob/master/WSL.md

My test is in a laptop Lenovo Carbon X1 Gen 10 with processor i7-1280p. I installed the latest Intel GPU driver (as in 9/30/2022) gfx_win_101.3430_101.2111.

I am using the follow configuration for WSL in c:\User\myuser\.wslconfig:

[wsl2]

Create /etc/apt/sources.list.d/clangofficial.list with the follow lines

deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-14 main
deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic-14 main

Add the key: wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add -

Note to self

This works with Clang 12 on Manjaro, and maybe other Linux versions. CUDA 11.1 is installed with pacman in /opt/cuda.
