Disable USB power saving for booting from USB

Having issues booting from USB connected SSD and disabling this in the Linux Kernal seems to solve the issues of the disk becoming unavailable.
Edit /etc/default/grub and change the following line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
Update the config with: sudo update-grub
Thanks to this post.

Chromium Hardware Acceleration Issues on Mint 18,2

I'm currently testing Mint18.2 and have run into a number of issues with Chrome. It initially started with corruption issues in Youtube.
After investigation I discovered that the hardware acceleration had been disabled. By adding the following switches to the 'exec' lines in /opt/google/chrome/google-chrome I was able to force all the acceleration options on:

  • --enable-native-gpu-memory-buffers
  • --enable-zero-copy
  • --disable-gpu-driver-bug-workarounds
  • --ignore-gpu-blacklist
  • --enable-gpu-rasterization
  • --enable-checker-imaging
I added these to the file by editing it with root (sudo) options. I suspect the file will be overwritten on update. There seems to be an environment variable for chromium which allows you to set command line options to pass to chromium without editing files, but I can't tell if this works for Chrome yet.

Unable to update Skype because of GPG error

Recently installed NHSbuntu on an SSD and added Skype but kept getting the following error when trying to run 'apt update':

W: GPG error: https://repo.skype.com/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3

Thanks to QwertyChouskie over at this thread for the answer:

Bug #1587975 “packagekitd eats all the CPU” : Bugs : AppCenter:

Elementary OS problems with packagekitd using all CPU after installation of Skype.

Seems that the Skype repo doesn't add the GPG key properly.

I only had to run these lines:

curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add -

sudo apt update

Installing Virtualbox Guest modules into Devuan

This involves the following:

1. Remove the cdrom as a package source
2. Add jessie-backports as a package source
3. Update the installation
4. Add the required packages

1. Remove the cdrom as a package source

As a privileged user, edit the /etc/apt/sources.list file and put a hash character in front of any line starting with 'deb cdrom':

$ sudo vi /etc/apt/sources.list

2. Add jessie-backports as a package source

Add the following three lines (if you're using the GB mirror) to your sources.list:

# jessie-backports
deb http://gb.mirror.devuan.org/merged/ jessie-backports main contrib
deb-src http://gb.mirror.devuan.org/merged/ jessie-backports main contrib

Adjust the URL if you are using a different mirror to what you are using for e.g. jessie-updates

3. Update the installation

$ sudo apt update
$ sudo apt dist-upgrade
$ sudo apt autoremove
$ sudo apt autoclean

4. Identify your kernel architecture:

$ uname -a
Linux devuan 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2 (2017-04-30) x86_64 GNU/Linux

4. Add the required packages, replace amd64 with the architecture identified above as appropriate:

$ sudo apt install virtualbox-guest-utils virtualbox-guest-x11 virtualbox-guest-dkms dkms linux-headers-amd64 build-essential

openvas | sil3ntcor3 ramblings

Running an 'apt dist-upgrade' on my Parrotsec install updated the version of OpenVAS and it would not longer start. I could see a message about "wrong database version" on feed update.

The link below got me up and running again.

I had to run:

  • openvasmd --migrate

Windows 10 Creators Update bumped to build 15063.250 with KB4016240 | On MSFT

Windows 10 Creators Update bumped to build 15063.250 with KB4016240 | On MSFT:

I'm hopeful the browser memory leak fix ss the one I observed and reported with regards to the Jetstream tests at http://browserbench.org/JetStream/ .

Edit: Edge still uses GB of memory and eventually crashes and returns to the start page before completing three runs of the test. Not sure if this is an Edge issue, or a combination of Edge and Sophos client v10.7. The same behaviour was seen with Sophos v10.6.

Playing with Open vStorage and Docker - Open vStorage BlogOpen vStorage Blog

Playing with Open vStorage and Docker - Open vStorage BlogOpen vStorage Blog:

Very interesting article on how to get vStorage up and running under Docker within VirtualBox. I managed to get a single node up easily but there were a few errors on adding the second node. vStorage seems to be a virtual storage solution that's able to replicate across disks, servers and locations while supporting compression, dedupe and encryption.

The line 'gzip -dc ovshc_unstable_img.tar.gz | docker load' should read 'gzip -dc ovshc_unstable_img.tar.gz | sudo docker load' and the URL to access the GUI should read https://IP_Address_of_VM.

Starting the second node seems to hang on the command 'sudo ./ovscluster.sh join ovshc2' hung with the status 'Status: Downloaded newer image for docker.openvstorage.org/ovshc/unstable:latest4417288f5ad21f5577e3fb4fe6ba25f4af0e71c277ab4d2cf554521c517469e6' and nothing else seems to happen after this.

I'd really like to see a tutorial to set this up on a physical Ubuntu server with RDMA but I can't seem to leave a comment on the blog. :(

Good article though, and thanks!

Join.me showing a black shared screen on Windows 10

I solved this by using the  Radeon Firepro settings app to use power saving for the join.me.exe file.

This forced Join.me to run under the Intel HD5500 card, and the graphics display correctly at the remote end.
