• Network does not connect at boot

  - by Daniel Svozil

  I am on Ubuntu 12.04, fresh install. When I boot a machine, the boot screen says Connecting to network, later it is changed to something like Did not connect, trying for another 60s. However, the network does not connect at the boot. But I can then log in without a network connection, and if I start a network manager service manually from the terminal (sudo service network-manager start), the network is connected without any problems. Please, does anybody know where the problem could be? I don't want to wait more than two minutes every computer restart :-). I am new to Ubuntu (and also to upstart) so I am a bit lost. There is no /var/log/messages, in dmesg I found this record, though it may not be related: init: network-interface (eth1) pre-start process (492) terminated with status 1 init: network-interface (eth1) post-stop process (548) terminated with status 1 Thanks Daniel

• Ubuntu on USB does not boot on MacBook

  - by Sean H

  Ubuntu is installed on a 32 gigabyte flash-drive and it successfully booted every time up until I partitioned my hard-drive and installed Windows as a secondary boot (for programming reasons). Now every time I attempt to boot the Ubuntu flash-drive it boots into Windows XP. The same goes for partitions, I partitioned my hard-drive and installed Ubuntu and it only booted Windows XP. I am on a MacBook 6,1 with Mac OS X 10.6.8, 2 partitions, and I am using ReFit as my boot-loader. EDIT: I had Ubuntu working fine from FLASH DRIVE and at one point as a partition. I later uninstalled Ubuntu from my hard-drive and installed Windows. I then had to re-image my computer for certain reasons and I installed windows. Now when I attempt to boot anything other than Windows or OS X it boots into windows. Ubuntu was never on my hard drive while Ubuntu was on it. The flash-drive has been its own thing and has the boot-loader installed to it and loads from ReFit but boots into windows.

• No lock screen when the right click menu is open

  - by Shivram

  I just found that the lock screen on my laptop does not show up when the right click menu is open. I discovered this when I pressed the right click button accidentally while closing the lid and the laptop went to sleep, but the lock screen never showed up when I opened the lid again. I am also not able to lock the system manually(with ctrl+alt+L) when the right click menu is open. Is this by design or is it a bug? I would assume that the screen should be locked automatically when the computer goes to sleep, but this doesn't seem to be the case. Anyone have any suggestions? My specs are: Dell Vostro 1500, Ubuntu 12.10

• unable to enter bios

  - by fraz

  I have an asus desktop ( amd phenom X6 processor) which was preinstalled with windows 7. I wanted to install ubuntu on it (dual boot) but am unable to do so because of the boot order. So I thought of changing boot order thru bios. But it turns out, if I press any key while the computer is starting, it just doesnt boots. I can see that the keyboard and mouse are booted up. (the lights are on) but the monitor is in standby mode.. I tried tab, f2,f10, delete key. But nothing is working.. Is there a software or other alternate on how can I change boot order ? Thanks

• How do I fool 12.10 to think it uses Unity2d in order to get the resolution my screen can use?

  - by Konstapel Kask

  On a laptop (model older) I have two screens (one built in, one external). I wish to use them both at the same time, but the settings app complains: Requested size (2944, 1080) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square or select the Ubuntu 2D session at login. The problem though, Unity 2D has been discontinued. I have forced Ubuntu to render Unity in 2D mode (with the help of echo export UNITY_LOW_GFX_MODE=1 >> .xprofile in accordance to this askubuntu post. But the error message still remains. How can one get the resolution that my computer supports? Or, how can I assure Ubuntu that it truly does use a 2D session?

• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• What is the simplest human readable configuration file format?

  - by Juha

  Current configuration file is as follows: mainwindow.title = 'test' mainwindow.position.x = 100 mainwindow.position.y = 200 mainwindow.button.label = 'apply' mainwindow.button.size.x = 100 mainwindow.button.size.y = 30 logger.datarate = 100 logger.enable = True logger.filename = './test.log' This is read with python to a nested dictionary: { 'mainwindow':{ 'button':{ 'label': {'value':'apply'}, ... }, 'logger':{ datarate: {'value': 100}, enable: {'value': True}, filename: {'value': './test.log'} }, ... } Is there a better way of doing this? The idea is to get XML type of behavior and avoid XML as long as possible. The end user is assumed almost totally computer illiterate and basically uses notepad and copy-paste. Thus the python standard "header + variables" type is considered too difficult. The dummy user edits the config file, able programmers handle the dictionaries. Nested dictionary is chosen for easy splitting (logger does not need or even cannot have/edit mainwindow parameters).

• My ASUS U32U with fresh Xubuntu install shows a black screen 50-80% of the startups

  - by Jona Ekenberg

  I have recently installed Ubuntu 12.10 with Xubuntu-package on my ASUS U32U notebook (Radeon HD 6320 GPU). The issue I have is that more often than not, after the GRUB-select screen I get a black screen, and three times total white lines (kind of) flashes very quickly (with maybe 5 seconds between each flash). I'm not even able to get to the login-screen (nor the Xubuntu loading screen). At first I thought it was simply me having installed something dumb or messed up some settings, but even after reformatting the partition and installing ubuntu again, the problem remains. Before I formatted it xfce4's window manager wouldn't start either, but it does now (when I am able to see anything). I can access the virual consoles (ctrl+alt+f1), but I can't see anything, but I've managed to shutdown the computer by using it (sudo shutdown -h now).

• Instruct Ubuntu to boot TORAM from flash drive using unetbootin

  - by Goyuix

  I have used UNetbootin to create an installable / live bootable flash drive from Ubuntu 12.04. However that didn't preserve the normal Ubuntu boot menu which allows to me to enter advanced options. It has a custom menu that I can pick from predefined choices like "Install Ubuntu" and "Try Ubuntu without installing". What I would like is to be able to boot from the USB flash drive, but then be able to remove it from the computer once the desktop has loaded. The laptop I would like to use this on does not have a CD/DVD drive. What do I need to modify on the flash drive to add an option to "Try Ubuntu (RAM)" that passes the TORAM=yes parameter to the initrd options? Are their other things I need to touch/change as well? Bonus: I would guess the answer would also allow for other options like acpi=off as well, but if it is different I would appreciate having that answer too.

• Bluetooth pairing works in 10.10 but not in 11.04

  - by Nathan Haines

  My laptop, a Compaq Presario V2000, has a built-in Bluetooth module that has worked well since at least Ubuntu 8.04 LTS. I use it to pair with headphones and a mouse. These both worked great in Ubuntu 10.10 (and still do with a live CD) but I cannot pair to any Bluetooth device in Ubuntu 11.04, even from a live CD. I can see the Bluetooth module in lspci and when I try to set up a new device from the Bluetooth indicator my computer detects all Bluetooth devices around me but pairing always fails. At the moment I'm most concerned with getting my Microsoft Wireless Notebook Presenter Mouse 8000 paired. Relevant output of lspci: Bus 003 Device 002: ID 03f0:011d Hewlett-Packard Integrated Bluetooth Module

• Remote GDM login

  - by luri

  Is it possible to remotely (via ssh) make a login to GDM? I'll explain a situation in which I'd need this: I'm on my laptop and connect to my desktop via ssh. I realize there are some updates available. I install them all, but I need to reboot the computer. The problem is that once the desktop has rebooted, there will be no GDM session available, since it's necessary to log in. Can I somehow perform the GDM login remotely from my laptop? Edit: I can't find FreeNX for Maverick, and I haven't been able to configure x11vnc + vncviewer to work. Isn't there an easy way?

• Why is Ubuntu unmounting my primary hard drive?

  - by Twisol

  I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out?

• How to install hardware drivers for my laptop

  - by John Flisk

  Everytime I change the OS I usually format my laptop. It is an HP tx-2 Touchsmart. It has a touchscreen and additional hardware that isn't working (i.e. volume control buttons and the network discovery) If I was on windows I would just download the hardware drivers from the HP website. How do I go about installing the software for the built-in hardware of my laptop? I am new to the community and I really want to get this computer working like it used to, to get the full Ubuntu experience. Please direct me, thank you.

• Why does qt-creator need to connect to google-analytics?

  - by Nanda

  I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

• Wrong notification on GNOME Shell?

  - by audrianore

  I just installed GNOME Shell on my 12.04 a couple hours ago. The notifications are just cool, and I installed shell extensions, and it works smoothly in 1 hour. Then I restarted my computer for some reason, start back in to GNOME. And I was surprised with the default notification showed up. It replaced the GNOME notifications! I tried to: Reinstall gnome-shell. (autoremove and install) Reset desktop configuration. But it didn't work at all. Is there anything I can do to fix it? Plus: I got a double notification (osd + gnome notification showed up) when someone chatted me.

• Bluetooth mouse contstantly failes to reconnect after sleep

  - by Peter NUnn

  It seems the bluetooth subsystem shows some bugs after the upgrade to 13.10. It was working quite happily at 13.04. The bluetooth mouse I have, simply won't connect after the computer goes into any sort of sleep and has to be re-added each and every time. Sometimes the the entire bluetooth stack has vanished alltogether. What changed with the bluetooth between these versions, that may cause this? This is a fresh install of Kubuntu I'm using (bluedevil) no an upgrade, but the same hardware as 13.04 was happy on. I have reported this as a bug https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/124698 and added the link here as requested.

• Cisco Linksys AE2500 wireless adapter not working

  - by makuto

  I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

• Unity Desktop not loading and ccsm method not working

  - by slimy-spork

  I installed Ubuntu 13.04 x86_64 on my HP Pavillion DV7-6c60us. It installs fine and works until I update. I run the software updater and reboot as it requests after. When my computer comes back on I get the desktop background but the rest of the Unity desktop doesn't load. I've tried the ccsm method and re-enabling but it just de-enables itself. I've also tried installing the gnome desktop but that does nothing for me either. I really want to switch to Ubuntu but this is causing issues. P.S. I've also tried using 12.10 and 12.04 with no dice.
