• Chromium web-app creation doesn't work in 12.10?

  - by speter

  If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result: 20:32 ~ speter Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden (English: "File or directory not found"). Can anyone explain or knows a workaround?

• How to connect to the internet via command line or graphical utility given I can't click at the top of the screen?

  - by Ben

  My Ubuntu 12.04 installation has an input problem resulting preventing me from clicking near the top of the screen. That is, there is an unclickable area, circa 60 pixels high and stretching all the way across the screen. I will ask about this in a later question. For now, I would just like to be able to connect to the internet, given this limitation. I am able to access the network connections application by hitting the super key and typing "network connections". There is a LAN and a wireless network available. The network icon in the bar at the top of the screen shows an empty wedge, which I suppose means that wireless is off. I've attached the cable for the Ethernet connection, but it does not seem to have connected automatically. How can I figure out what's going on? (I'll happily edit in the output of any relevant terminal commands.) Thank you.

• Window controls missing; Cannot maximise or minimize applications

  - by omg_scout

  Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

• Would security be comprimised if I install a gui (e.g. zPanel) for LAMP?

  - by Kirk

  I am an Ubuntu/Linux noob. There are many questions I have regarding the use of my system as a server. First and foremost is security. I want to install a simple GUI (zPanel appears the most user friendly) that will allow others to log into the server and database with ease, similar to a hosting service, though my intent is for the development of one site. Upon looking at the instructions of numerous GUI's, they require installation as root. This makes me uneasy, as my thoughts spiral to the possibilities of the developers creating the elusive 'back-door', thereby giving them root access to my entire system. Am I just being paranoid or is that theoretically possible? If it is possible, what steps are necessary to ensure security?

• How to reduce noise in Skype?

  - by tkc

  According to Alsamixer I do have a HDA Intel soundcard with Nvidia MCP77/78 HDMI chip (Realtek sound card on MSI notebook). When I use Skype under Ubuntu 12.04 for video calls, the other side hears background noise such as in Windows when you have your microphone boosted. In fact they can hear everything, even the fans turning on. There is nothing tweaked on Ubuntu's fresh installation. Also tried this site: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages , but there are no *.deb files that I can test if any fix the problem. The question is if there is a way to add/tweak something to enable on software level the noise cancellation like the Windows sound drivers have that option. I use my build in mic.

• How can I fix my problems with fonts in Firefox?

  - by snostorm

  Ever since I reinstalled Ubuntu a few hours ago, I've experienced major visual artifacts with smaller font sizes in Firefox. The fonts end up looking like this: Or even like this: This only occurs in Firefox; other applications are unaffected. It also occurred on the LiveUSB I used for installation, making me suspect a hardware or driver issue. The output of lshw on my computer is here: http://pastebin.com/LnSt6veT. Any idea what might be causing this, or how I can fix it? ... and "Use Google Chrome" is not a valid answer. ;)

• video/audio output via HDMI Ubuntu 12.04

  - by lostNfound

  I've been out of the Ubuntu loop for quite a while now and have a completely new laptop now. Just installed Ubuntu 12.04 64-bit and would like to output my video and my audio via HDMI to my television. the following is the lspci | grep VGA for my computer. please tell me if there is any additional information needed and preferably how to obtain it and i will be more than happy to oblige. thank you in advance for your time and assistance in this matter. 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1) Edit: every time i restart my computer, after a short moment, i get an error message stating something along the lines "sorry, jockey needed to close unexpectedly." after researching, i discovered jockey is the name of the "additional drivers," which after initial installation, ubuntu informed me of proprietary drivers available. those are no longer available, and this error continues to occur.

• Ubuntu gets slower by the day

  - by Doug

  Ive noticed that Ubuntu has been getting slower and slower to boot, launch programs, etc. I installed 12.04 about 4 months ago,now 12.10, running on a quad-core Q8300 Intel, 4GB Ram, and an 80GB WD IDE drive. For some reason (ever since 11.04), Ive noticed after installation, the speed is good. The longer I have the OS installed, every bootup gets slower and slower, launching programs get slower, frame rates change radically(onboard GF9400 gets anywhere from 60fps down to 12 in worst cases). I would think maybe the HD is the issue, however I installed 11.10 on a 160GB SATA, and the same thing occurred. Looking at system resources, I'm holding steady at 1GB memory usage (I have 4GB, but it's actually showing 3.6GB, dunno why), no swap usage, and using right around 4% on cpu currently. HD capacity is only 28% used. Has anyone else ran into this issue? I love Ubuntu to death, but using other distros other than Ubuntu, I dont have this problem.

• Fonts totally unreadable

  - by user11181

  I've just upgraded from 10.04 to 10.10 and my fonts are all just small rectangles with nothing in them. They are completely unreadable. EVEN THE FONTS IN THE TERMINAL. Thank god the fonts in my Chromium were ok, because I wouldn't be able to find this site or write this message. So far I've tried to use the Appearance - Font thing and it doesn't work. For some reason there was an error with the fonts during the installation. Please help, this is an utter nightmare...

• Broadcom bcm4311 rev2 Full disabled on battery

  - by Antonio BG

  Ok this is my problem... My problem begins while ago when I installed ubuntu 10.10. (is the same with 11.04,11.10...) My wireless card is disabled if the power cord is unplugged, and the only way to fix this is rebooting my pc WITH the power cord plugged and if I use lspci command, it doesn't show me the wireless card. is like if I've removed the wireless board from my laptop port. I've searched a lot of solutions for bcmw4311 issues, but none of them fix my problem because when apply one of the fixes, if I unplug the cord, my wireless card it just gone away... I have dual boot on my pc(w7,ubuntu), I've tried with full installation just to see if this is the problem, but not, is the same. On windows all work correctly with and without power cord.. so this is not a hardware problem, is more like a kernel problem. anyway I can use wireless with power cord plugged, but c'mon this is a laptop not a desktop pc XD haha any help is welcome

• .htaccess 301 Redirect for wildcard subdomains

  - by Steve

  I run Wordpress in Network mode, which means I can have multiple websites running off one installation of Wordpress. Each website runs as a subdomain. Wordpress handles this using .htaccess, and a wildcard subdomain pointing to the location of Wordpress, so there are no actual subdomains created in cPanel; just a wildcard subdomain in cPanel, ad Wordpress handles the rest. I want to 301 redirect http://one.example.com/portfolio to http://two.example.com/portfolio. If I only have 1 .htaccess file in the web root of example.com, how do I achieve this?

• How do I get to the maintenace shell?

  - by Narida

  I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

• phpMyAdmin says: $cfg['Servers'][$i]['userconfig'] ... not OK

  - by Palantir

  I have installed phpMyAdmin and it works fine. At the bottom of the pages however, there is this error message: The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why click here. In that page, the only red row is this: $cfg['Servers'][$i]['userconfig'] ... not OK [ Documentation ] User preferences: Disabled In the configuration I have this: $cfg['Servers'][$i]['userconfig'] = 'pma_userconfig'; The pma_userconfig was missing from my phpmyadmin db so I found the create_tables.sql from my phpMyAdmin installation and I ran that, then restarted apache and mysql. The table has been created, but the error is not gone. Thanks!

• How to grub-install ignore specific drive/partition

  - by gsedej

  Is it possible to use grub-install or update-grub to just search on specific disk/partition? (or ignore specific)? I installed Ubuntu 12.04 on my hard drive, but i wished to do some testing on it without harming current installation, so I "rsynced" root partition (the only) to the USB partition (ext4). I did fix /etc/fstab on USB partition. The problem is that when I do grub-install /dev/sdb (usb) GRUB seems to confuse when UUIDs. Whatever I chose in GRUB it always boot from disk. In grub in edit mode I see that in two "UUID" lines are not the same. If I retype UUID from "first" to second "line" it boots from USB (as I wish). Is there any other way than fixing /boot/grub/grub.cfg each time? EDIT: the GRUB generated good when I booted from USB and grub-install from there, but question is still if it's possible ignore drives

• I installed Ubuntu alongside Windows but I can't see it in Windows' boot menu

  - by André Hallé

  I have a second machine where Ubuntu 12.04 LTS and Debian Squeeze are installed on the same HD and when I boot, I have this grub menu where I can choose which partition I will used. It works perfectly! But in my Windows environment that's another story. Now after making almost everything that I know, to make it work along Windows 7, there is no entry in the boot menu of Windows (I know, Ubuntu use grub but anyway there is surely a way to fix it, access it?). Why there is no Ubuntu entry? Why the installation gave me no error while I have this strange situation of having a "ghost OS" called Ubuntu installed somewhere in my second HD in a partition made especially for it and not being able to access it, starting it, having it working? Am I wrong? If I am, what's the problem? If I'm not, what's the need of Wubi?

• After Upgrading to 12.04 the Kernel won't Initiate

  - by Jeff

  I had 11.10 and tried to upgrade recently, via the installer pop-up reminder. Afterwards it would not boot, citing an issue with the kernel. So I've setup a 12.04 installation USB, which appears to work fine. The problem is it doesn't provide an upgrade option, just format and install or install alongside the current broken kernel. I believe I should be able to still get the information from the broken OS after installing alongside, but if there is a way to fix this more directly that would be preferable.

• Various crashes in 12.04 after upgrade and fresh install

  - by stefan

  Ubuntu drives me crazy. Since I upgraded from 11.10 64-bit to 12.04 Ubuntu crashes regularly. One time the crash report tells me that Skype is the faulty app, another time it was Opera, and today the crash report tells me Xorg crashes. I read that it can be caused by a faulty upgrade so I made a clean new installation of 12.04 32-bit. But the error is the same. I had a look in the log files with a friend but we did not find a answer. This morning the crashes happened like this: Boot Auto-start Thunderbird Start VLC for radio Start Opera Working a while (30 minutes) Starting Skype 2 minutes later, the system freezes, the monitor turns black, a login screen appears and I enter my password. The desktop comes up again and the crash report pops up.

  I have a problem with the MATLAB 2012 installation. After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that. This made me happy, but only for a while because as soon as I try to search for Matlab within the applications I cannot find it and neither if I try to run matlab into terminal it says: command not found Can someone help me!?

• How do I get a matching theme when I run a program as root?

  - by NES

  I use a Metacity theme in my Ubuntu installation. Unfortunately it isn't activated for programs with Gui that are started as root user and some other other certain programs like gufw (when i start gufw by commandline not as root)? It uses an old not very eyecandy Theme. For example for Gufw is gives the following output on commandline: /usr/share/themes/Finery/gtk-2.0/gtkrc:365: error: unexpected number `0', expected number (float) /usr/share/themes/Finery/gtk-2.0/gtkrc:365: error: unexpected number `0', expected number (float) What could be the reason, is there a way how to enable this theme also for these programs?

• How to prevent a 404 Error when creating a subdomain and using www to access it?

  - by Chris

  I have installed a multi-site installation of WordPress onto my domain. I then added the necessary code to the wp-config.php file and .htaccess as instructed by WordPress. I also installed a plugin called Quick Page/Post Redirect Plugin which allowed me to place a 301 redirect onto the main domain as I only want to use the sub domain and not the main domain. Then I also added the following line of code to the wp-config.php file to redirect the main domain define( 'NOBLOGREDIRECT', 'URL Redirect Address' ); The site works fine with a redirect on the main domain and my subdomain runs fine when you type in subdomain.example.com or http://subdomain.example.com. However when I enter www.subdomain.example.com or http://www.subdomain.example.com the following error message is returned: Not Found The requested URL / was not found on this server. Apache/2.4.9 (Unix) Server at www.subdomain.domain.com Port 80 Any help with this would be much appreciated.
