AMD ATI Graphics tearing in Chrome on Ubuntu 15.04

I had to switch to using proprietor AMD drivers as the open source ones don’t support audio via display port, but after switching, Chrome was tearing and just going completely black.

The chrome GPU page reported no hardware acceleration enabled.

So I went to Chrome Flags page and forced GPU acceleration and rasterisation

Override software rendering list -> Disabled
Enable GPU rasterization -> Force enabled on all layers
Smooth Scrolling Linux -> Enable

How to connect to CloudFoundry’s Loggregator directly via WebSockets

Firstly make sure you can run the standard CloudFoundry cli:

cf logs [APP_NAME]

Then turn on tracing:

export CF_TRACE=true

You will see a HTTP request and then it will switch to a secure WebSocket:

WEBSOCKET REQUEST: [2015-04-22T11:27:22+01:00]
GET /tail/?app=[APP_GUID] HTTP/1.1
Host: wss://loggregator.[YOUR_CF_DOMAIN]:443
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Version: 13
Sec-WebSocket-Key: [HIDDEN]
Origin: http://localhost
Authorization: [PRIVATE DATA HIDDEN]

As you can see the Authorisation header is hidden, but fear not if look in ~/.cf/config.json under “AccessToken” thats all you need ("jq .AccessToken ~/.cf/config.json"). Combine this with wscat and you are good to go:

wscat -c wss://loggregator.[YOUR_CF_DOMAIN]:443/tail/?app=[APP_GUID] -H Authorization:$(jq .AccessToken ~/.cf/config.json)

Intel Graphics Installer on Ubuntu 14.10

So if you just downloaded the latest Intel Graphics Installer and just found that it doesn’t support Ubuntu 14.10.

Fear not you can trick it into installing by doing the following:

First backup

sudo cp /etc/lsb-release /etc/lsb-release.backup

Then edit the file

sudo nano /etc/lsb-release

And put the following in there


This will allow the installer to proceed but you will also want to add the public key so updates work correctly:

wget --no-check-certificate -O - | sudo apt-key add -
wget --no-check-certificate -O - | sudo apt-key add -
