Apache 'You don't have permission to access / on this server'

- by Dying

I just install apache2 on ubuntu,the default www directory is /var/www/ ,I use ln to link it to '/media/Software/Program Files/wamp/www/' at the windows directory,but the apache shows 'You don't have permission to access / on this server',Then I use 'sudo chmod -R 777 /media/Software/Program\ Files/wamp/www/' to set the permission,but it didn't work,and nothing changed when I saw the permission in the preporties of the '.../wamp/www' folder.So I want to know How can I change the www directory to '.../wamp/www' as I also need to access this diretory in windows.

Unable to install libcairo2:i386 on ubutu 12.10 X86_64

- by user63726

I get the following error. I think it is a bug. Is there a workaround? There is mismatch between the 32 and 64 bit version of this package. apt-get install libcairo2:i386 Reading package lists...

How do I install drivers for the Atheros AR8161 Ethernet controller?

- by Jessica Burnett

I have installed Ubuntu 12.04-64 bit on my Lenovo IdeaPad laptop, and the wired Ethernet (LAN) connection doesn't work. Running the lspci -vv | grep Atheros command from the terminal shows me I have the AR8161 Gigabit Ethernet controller: 02:00.0 Ethernet controller: Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 08) This looks like a new product whose drivers are not built into Ubuntu. How do I install drivers to get the AR8161 working?

How can I change the default location of content directories (eg Pictures, Templates, Music) in my home folder?

- by Casey

I have multiple users on my home desktop. I am content with most of the default user directories, however I would like to make one change. I would like to setup a common directory for Music (ie /home/common/Music/) that is writable to all users and Nautilus/Dolphin/whatever recognizes as the user's Music directory. I know that it would involve changing the xdg user directory setup, but everything I see points that it is relative to the user's $HOME. Is there a way I can specify an absolute path?

Intermittent temporary GUI freeze in Ubuntu 11.10

- by Oscar

I've been using Ubuntu 11.10 for a month or so. In the last week it's started freezing randomly (every few hours or minutes). I can still move the mouse and switch to other terminals with ctrl+alt. I thought this was purely a gui issue as I could continue entering commands (mouse clicks and keys) which seem to be processed once the system resumes (generally 30 seconds to a few minutes). I'm using gnome and metacity. I can't identify anything in particular that triggers the freezes. Saving a file in LibreOffice causes the system to hang. I tried disabling most of the services I've installed (dropbox, autokey, etc.) but doesn't help. Switching to another terminal and running top, the CPU column is shared equally among all of my processes (i.e. non-root). I have no idea what that signifies. My PC is unusable in this state.

What is the version numbering logic for open source developers managing software releases?

- by Stephen Myall

I guess this is more of a general question that I cant find the the answer to anywhere. What is the version numbering logic for open source developers managing software releases and is there any governance or guidance I can read up on. The origins of this question comes from me reviewing and researching software on countless websites that I would like to use on my Ubuntu OS. Through experience, I am learning some sites are much better than others explaining if a release is a stable, experimental or maintenance release but these explanations are not consistent with any version numbering logic I am familiar with.

How to hide (in Thunar and Nautilus) a directory without putting a dot in its name?

- by Ivan

Usually Linux programs store user's settings in ~/.* directories. But unfortunately some developers (of some applications I need) do not follow this rule and don't start their settings storage folders names with a dot. This results in never-user-used folders cluttering (not the right word perhaps, as there are not many, but they annoy anyway) a home directory. Renaming them is not an option, as the applications won't find them in this case (and will create them again). Is there a way to hide a folder having no dot starting its name from being displayed in common file system browsers (I actually use Thunar of XFCE, alongside with Midnight Commander and Krusader, but wouldn't mind to know about Nautilus too).

Using External Monitor with Laptop Monitor as separate monitors

- by user14623

I am trying to use 32"LCD monitor with my ubuntu 10.10 installation. I am trying to use my laptop screen and external monitor at the same time but having two separate desktops. I also want to use my laptop with 1280x800 resolution and external one with 1920 x 1080 using VGA. However, ubuntu sees my external LCD as a CRT and provide 13....x... resolution at the best not above. My graphics card driver is Nvidia 270.... driver. Is ubuntu capable of using two monitors separately or should i give up? Thank you

Compiz stop working

- by Aikanáro

I'm on a laptop sony vaio, vng-nw330f with ubuntu 11.10. One day I used my computer normally, I shutdown and the other day when I turn on it again, all was different. Compiz effects is not working at all, it doesn't matter what plugin (from ccsm) i enable or disable, nothings happens, nothings changes. I tried next commands: unity --reset unity --reset-icons sudo rm -rf .config .gnome .gnome2 .gnome2_private .compiz .icons .fonts .nautilus .themes .qt .local (from my home directory) gconftool-2 --recursive-unset /apps/compiz-1 I try reinstalling compiz (I remove compiz from software center and installed it again). I have just a couple of weeks using ubuntu, I'm not sure if exist a desktop call it unity 3d, but I think that it's missing. I want the graphics interface of ubuntu 11.10 by default.

How can I break out of ssh when it locks?

- by Wayne Werner

Hi, I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - ^c, ^z and ^d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. when the pipe fails "normally" it will exit with a message about a broken pipe)? Or do I have to figure out what the PID is and manually kill it? Thanks!

Ubiquity crashes when installing from CD

- by Ashes

I didn't want to take any risks so I ordered a CD from Canonical to get Ubuntu. Thing is, another CD was given to me about 2 days before the CD from Canonical got to me, so I installed Ubuntu 10.10 but there was a problem with the login screen (When the Ubuntu logo should be displayed, it wasn't, instead it would just say "Ubuntu 10.10") so I decided to reinstall Ubuntu 10.10 with the CD that arrived a few days later. Whenever it's finishing the installation, the installer (ubiquity) crashes, or sometimes it gets to the part where the boot loader should be installed and for some reason it is unable to install the boot loader (if I choose not to install it, I don't get how to start Ubuntu, since you have to reboot my laptop after the installation is over). I'm currently running Ubuntu 10.10 from the CD I ordered, since I have no other OS on this laptop.

apt-get does not work with proxy

- by tommyk

For a command sudo apt-get update I get following error W: Failed to fetch http://ch.archive.ubuntu.com/ubuntu/dists/maverick-updates/multiverse/binary-i386/Packages.gz 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) I am running Ubuntu 10.10 installed on Windows XP using VirtualBox. For internet connections I am using proxy server with an authentication. I tried to use gnome-network-proxy tool to set proxy settings system-wide. After that /etc/environment has been updated by http_proxy variable with the format http://my_proxy:port/, there were no authentication data. I checked this with firefox. Browser asked my for login and password and everything was working fine. It was unfortunately not the case for apt-get. I have also tried to do as described here. Unfortunately it does not work. May it be somehow related to the fact that a proxy is in a Windows domain, any ideas ? EDIT: My proxy name is http-proxy. Is '-' a special character here ?

Dual LAN Printing

- by Christopher

I want to use Ubuntu 10.10 Server in a classroom, a computer lab whose bandwidth is provided by a local cable ISP. That's no problem, though the school network has an IP printer that I want to use. I cannot reach the printer through the cable Internet. But, I have two network cards. How is it possible to use both networks at once? eth0 (static 192.168.1.254) is plugged into a four-port router, 192.168.1.1. On the public side of the four-port router is Internet provided by the cable company. I also have the classroom workstations plugged into a switch. The switch is plugged into the four-port router. The whole classroom is wired into the cable Internet. The other NIC, eth1, could it be plugged into an Ethernet jack in the wall? It uses the school network, and I might receive by DHCP an IP address like 10.140.10.100, with the printer on maybe 10.120.50.10. I was thinking about installing the printer on the server so that it could be shared with the workstations. But how does this work? Can I just plug eth1 into the school network and access both LANs? Thanks for any insight, Chris

virtualbox host | Ubuntu vs XP

- by iambriansreed

In order to lengthen the lifespan of my machine I am replacing the weakest link, the hard drive and installing a new OS. I had planned on using xp pro as my virtualbox host and ubuntu as guest. After messing with ubuntu desktop and server I am really impressed and am thinking of reversing the virtualbox setup; ubuntu host xp guest. I would use XP for Adobe Fireworks, Netflix, and iTunes (maybe) that's pretty much it. Any reason not to do ubuntu host with xp guest? I know the xp vbox will run slower as a guest but really how much slower? It's a desktop. 4gb ram, 500gb disk, Pent D 3.2 ghz

How do I know if my system is capable of playing 24bit/96kHz sound?

- by Igor Zinov'yev

Let me state for the record that I'm a total noob when it comes to Hi-Fi sound systems, but I am rather picky about the sound quality. Normally I listen to CD recordings ripped to FLAC in 16/44, but I have several albums that are also ripped from vinyls to FLAC in 24/96. But it seems that I can't tell the difference between 16-bit and 24-bit versions (except for some vinyl noises, of course). That can be due to several reasons: my equipment (onboard audio, monitor headphones) isn't good enough to make any difference, my system is not playing audio in 24-bit 96 kHz, I am physically unable to hear the difference. So here is my question, how do I tell if my system can play 24-bit sound with 96 or 192 kHz resolution? And if it can, how do I tell that it plays it instead of downsampling to 16-bit / 44 kHz? Also, what hardware (audio cards, amplifiers, etc.) would you recommend to play such recordings on Ubuntu?

Wifi works but doesn't start automatically on ubuntu 11.10

- by Nikita Kononov

Good evening everyone, I have got an issue which I hope you will help me to solve. I was trying to update my Kernel in ubuntu from this web-site http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-rc4-oneiric/ And everything went smooth. But, for some reason, my wifi doesn't work in new Kernel so I decided to switch back to my old one 3.0.0-17 generic and to my surprise WIFI doesn't start automatically eventhou it was working. What I mean is that I have to click on wifi icon and put a mark Enable Wireless. This is not a really serious issue but I don't like switch on everytime at log in my WIFI because before that it was working when system started. What is the cause of this and how to fix it. Thank you very much for you help.

Creating a GTK theme, but Qt and Java apps are not affected, and title bar button layout is ugly

- by Mr. Pixel

I'm playing with a gtk2 / gtk3 theme which I use in the Mate desktop. Everything is looking well, even gtk3 apps, but I still have 3 important issues: Java apps ignore the theme QT apps ignore the theme I'm using those nice ubuntu 10 title bar buttons, but the problem is, when only the close button appears, the title bar looks ugly. Can I make it so that it shows the two other buttons, but disabled? I don't know how Ubuntu 10 handled this. Here's a screenshot showing the 3 problems (above is a small java app, below is a Qt app): Under my previous desktop environments, Unity and Cinnamon, both apps seemed to be taking the right theme correctly, but I did not use my custom theme yet. Cinnamon is based on gnome-shell by the way, and mate is a gnome2-fork. Please note that the shown java app explicitely tries to load the gtk theme at runtime. By default, java apps don't, but this one has the necessary code, which worked in unity and cinnamon. Any suggestions how I could make my theme better so these problems disappear? Thank you very much!

Bad 3D Performance in Ubuntu 12.04

- by Pandem

I already posted a question before but I didn't really get any advice/help. I'll be a bit more brief/general in hope it'll help. I have an MSI HD 7850 with the Catalyst 12.4 drivers installed. I've found that I'm having bad 3D performance for some reason but I'm not entirely sure what. I suspect it may just that the graphics card is new and AMD just need to work on their drivers but it would be nice to get advice and narrow the problem down so that I can be sure rather than wait for driver updates that may not even help. I ran gxlgears to give some general idea of how bad the performance is. At default size it is averaging around 2000 FPS. The command glxinfo confirms the renderer is using AMD Radeon HD 7800 Series with OpenGL version 4.2. Edits below: As asked for others: lspci -v output is here. fglrxinfo output is here xvinfo output is here glxinfo | grep rendering says yes for direct rendering. These confirmed that everything was configured correctly. Within Unity and Gnome Classic: glxgears had an FPS of around 2000 FPS fgl_glxgears had an FPS of around 544 FPS Within LDXE: glxgears had an FPS of around 4600 FPS fgl_glxgears had an FPS of around 1600 FPS In the end it was discovered that Compiz was causing a large performance decrease and solution was simply to change window manager for the time being. Thanks to TechZilla for all his help!

Low graphics mode on Ubuntu 12.04 with Intel Graphics

- by NightShadeQueen

When I boot, my computer just tells me it can't detect graphic card (or something else) settings and it has to use the low graphics mode. Then it gives me four choices, but doesn't let me choose any of them. I can get my computer to boot by going to some sort of terminal mode and then typing sudo gdm. The other graphics manager I have is lightdm. I originally had the nVidia propriety driver, and I've tried bumblebee. Mobile Intel Graphics Media Accelerator 4500M is my graphics card. Is there any way to fix this so I can use lightdm again?
