Other Issues

Google Chrome does not open with default PDF application

1. Disable the chrome pdf plugin Write about:plugins in the Chrome address field. Disable the PDF plugin.

2. Restart the browser

3. Klick on a pdf-link at a web page Chrome now downloads the pdf file. On the buttom of the page (left side) then you can see the downloaded file. klick on the little arrow beside the filename and select "always open files ..."

Now Chrome will open the pdf with your default ubuntu pdf browser (which you have to configure in Nautilus -> right mouse key -> open with).

AWN and run apps dialog

There is a problem with using AWN and the run apps dialog (Alt+F2).

It simply doesn't work any more, when you disable gnome-panel which you have to, if you like to run an awn only desktop. Gnome-panel can simply hindert from beeing started with the following shell command:

sudo chmod -x /usr/bin/gnome-panel
sudo killall gnome-panel

A good replacement for the build-in gnome-panel run-dialog is Gmrun:

sudo apt-get install gmrun

Then do the following steps:

1. disable the run dialog in: Settings -> Compiz Configuration settings -> Gnome comaptibility
2. disable the Alt+F2 key combination
3. add a new key combination for gmrun and assign Alt+F2

And the best: now the launch entry in the awn main menu is working too.

Faster internet browsing

1. Disable IpV6:

> vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Reboot.

2. Install a Webproxy:

> sudo apt-get install squid

Squid runs on port 3128. I recommend to take the following entries in the configuration file (according to [1]).

> vim /etc/squid/squid.conf

http_port 3128
#http_port 10.0.0.1:3128
#http_port 10.0.0.1:8080

# icp_port 3130
icp_port 0
 
#  TAG: no_cache
…
#We recommend you to use the following two lines.
acl QUERY urlpath_regex cgi-bin \?
no_cache deny QUERY

#Default:
# forwarded_for on
forwarded_for off

#Allow ICP queries from local networks only
icp_access allow localnet
icp_access deny all

# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
#acl localnet src 10.0.0.0/8    # RFC1918 possible internal network
#acl localnet src 172.16.0.0/12 # RFC1918 possible internal network
acl localnet src 192.168.0.0/16        # RFC1918 possible internal network

sudo /etc/init.d/squid restart

Flash buttons don't respond

According to [2] edit a line export GDK_NATIVE_WINDOWS=1 in the following file:

> gksudo gedit /usr/lib/nspluginwrapper/i386/linux/npviewer

[...]
export GDK_NATIVE_WINDOWS=1
. /usr/lib/nspluginwrapper/noarch/npviewer

Restart the browser.
