• Ubuntu 12.04 Hangs with Software Center open then opening Dash Home

  - by Josea

  I have a Dell D610 - Intel graphics - 1 Gig RAM. I have test the hard drive and RAM and both are fine. When I open Software Center, then Dash home my system locks up. The mouse cursor moves but is unresponsive if I try to right or left click anything. The keyboard is totally unresponsive and I have to hold the power button to power off! I have reinstalled from CD, did all updates but the issue persists. I tried using the track pad only, and I plugged in an external mouse also but no change. Everything else works great ! I am sick of running Vista and have no love for Metro! Thanks for any suggestions, on a scale of 1 to 10 (Newbie - Expert) I am about 3

• Where does Ubuntu Software Center store its (language) settings?

  - by guntbert

  On a fresh install (13.04) I see a strange mix of languages in Software Center The menu (like my system language) is in English, but the descriptions are in German. I want the descriptions in English too. I am using a german keyboard and have German installed too (for giving support to students with German as system language :-)) In system settings I have moved German below English - so it should be ignored, I have logged out after that. I have cleared the "Software Center Cache" with Ubuntu Tweak. The picture remains the same.

• Network doesn't work after upgrading to 13.10

  - by Inkbug

  I upgraded from 13.04 to 13.10, and a number of things stopped working. Most importantly, I don't have internet access anymore. When I go to the network settings, I receive the following error: The system network services are not compatible with this version. The only settings that show up in the network settings are the proxy settings. I tried sudo service network-manager start and sudo service network-manager restart, but it told me the service was already running. In addition, the menu bar is missing all of the indicators (such as keyboard layout, sound, network, clock, and the gear icon). Is this related or a separate issue?

• (My) Sun Ray 3i

  - by user13346636

  Last week, some Sun Ray devices were shown at the LASDEC exhibition. Afterward, they were brought back to the Aoyama Center, but not all of them found a place to be stored. So, two days ago, Iwasaki-san, one of the co-workers I've been close to (and who was at the exhibition), put a Sun Ray 3i (all-in-one with 21.5" screen) on my (shared) desk. Yay! I managed to get a Japanese keyboard, and now I can access my card and cardless sessions from Germany, and the performance is just great, as good as when I work from home in Hamburg. That's the way my deskt looks now,almost as messy as my desk in Hamburg: And my back is very grateful.

• How to avoid movement speed stacking when multiple keys are pressed?

  - by eren_tetik

  I've started a new game which requires no mouse, thus leaving the movement up to the keyboard. I have tried to incorporate 8 directions; up, left, right, up-right and so on. However when I press more than one arrow key, the movement speed stacks (http://gfycat.com/CircularBewitchedBarebirdbat). How could I counteract this? Here is relevant part of my code: var speed : int = 5; function Update () { if(Input.GetKey(KeyCode.UpArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.RightArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.LeftArrow)){ transform.rotation = Quaternion.AngleAxis(315, Vector3.up); } if(Input.GetKey(KeyCode.DownArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } }

• Screen Brightness Stuck on high on an HP dv7t laptop

  - by theJollySin

  I have an otherwise fully-functioning install of Ubuntu 12.04 on my HPdv7t laptop. When I press the 'brightness buttons' on the keyboard the associated images appear on my screen to say I am increasing/decreasing the screen brightness. When I go into "System Settings" I can move the 'brightness slider bar' up and down. But none of that changes the fact that my screen is stuck on the highest brightness setting. ANY clues on how to fix this would be greatly appreciated. This giant 17-inch monitor is blinding, and this is making it hard to code for any length of time.

• No video signal after install

  - by tW4r

  Today I tried to install Ubuntu 12.10 to my machine, but all the time I encountered the same problem, I successfully boot from Ubuntu 12.04 DVD, and a purple background comes up with accessibility and keyboard icons at the bottom of the screen, then when you wait a while a monitor text comes up "No signal" (Keep in mind that this signal is only shown when there's cable in the monitor HDMI plug), and nothing happens, a little later disk drive stops flashing meaning that disk finished being read. Even if you reset the computer you still get no signal, you have to turn the power of and on again, and plug HDMI out and put it in again. My info: Graphics card: ATI/AMD Radeon HD 4850 Connection to monitor: HDMI Monitor: Samsung SyncMaster T220HD

• Ubuntu freezes while working

  - by webid4me

  Ubuntu on my laptop has frozen multiple times in last 6-7 months. Its not frequent but I can not relate the freezing to anything which I was doing. Today it froze again when I was taking notes in class - approximately at 12:00 PM. During the freeze both mouse and keyboard stopped working. I tried Alt-Ctrl-F1, Alt-Ctrl-F2 etc without any success. After that I waited few minutes & then I restarted the laptop. I checked /var/log/syslog and /var/log/kern.log and it seems that it did not log anything (I was not able to understand most of it). Please let me know if you can find something unusual at around 12:00 PM. Is there any other log which might be useful? Here are the /var/log/syslog and /var/log/kern.log files.

• How to run CLI commands from the launcher?

  - by user50849

  I press ALT+F2 key on my keyboard, and get the launcher HUD up. From there I enter a command as I would in a shell, specifically vlc ~/Music/* -Z. If done from a shell, vlc starts and begins to play music. However, when done from the launcher, VLC replies: File reading failed: VLC could not open the file "/home/[username]/Music/*". (No such file or directory) user Your input can't be opened: VLC is unable to open the MRL 'file:///home/[username]/Music/%2A'. Check the log for details. I can't quite figure out what the difference is.

• Binding hotkey for toggling wireless card state - System76 Bonp3

  - by user109076

  Recently, my wireless card shut off on my laptop (System76 Bonp3 running Ubuntu 12.04 LTS). Awhile back, my keyboard had a meeting with a cup of coffee, and my F11 key no longer works. The key binding for turning my card back on happens to be Fn + F11, so I cannot turn my wifi on. The only solution I can think of is to somehow change this to be bound to another key. I'm looking for the script that handles this particular hardware switch so I can bind it elsewhere.

• sometimes, strange audio distortion(peeping, scratching), ubuntu 12.04

  - by richi902

  i have a problem with my sound in ubuntu 12.04. the problem is, that sometimes out of nowhere, when switching songs, or playing youtube videos, changing volume with my keyboard buttons, that the sound gets distorted(peeping, scratching). i dont know if it is related, but when i skip through music in rythmbox, there is also a little scratching noise. i can sometimes temporarly fix it: for youtube videos, i refresh the page, and sometimes it works agian normal, mostly not. for audio playback with rythmbox, i have to pause the song for sometime, and resume it, and hope that it works. before all that,i have changed my soundcard to "Analog Surround 5.1" in the sound settings from ubuntu, but i also used alsamixer to change it from 2 channels to 6 channels, since changing in ubuntu sound settings alone wasnt enough to make the other speaks work. i use a ASUS P8-H61-M LE B3 Revision Motherboard. which has a built in surround soundcard.

• Can I use Unity with XMonad?

  - by geniass

  I've been using Fedora for a while, but I recently decided to upgrade my ubuntu installation from 12.04 to 12.10. While I was using Fedora, I found xmonad tiling window manager which I sort of got working with xfce. I really like xmonad and I now automatically use the keyboard shortcuts without even thinking. So I would like to use xmonad with unity. Now, I have seen several blog posts etc. that explain how to setup the whole thing in 12.04, with Unity2D. But now, Unity2D has been removed, and the old methods no longer apply. I have read that Unity is actually just a Compiz plugin, and that the wm can't be replaced. Does no version of Unity have a replaceable WM? I've also tried MATE (GNOME2 fork) with xmonad on 12.10 and that is totally broken for me, but that's for another question.

• Ctrl+Alt+T doesn't open Terminal (Compiz related?)

  - by TheDevo

  Ctrl+Alt+T doesn't open the Terminal, and I'm pretty sure it's got something to do with Compiz. Compiz disabled the transparency on my launcher (using Ub.12.04LTS+Unity) and so I uninstalled it. But after I uninstalled Compiz, my UI was messed up, so I reinstalled it, now Ctrl+Alt+T doesn't open the terminal. System Settings Keyboard Shortcuts has the shortcut to terminal there, but it simply does not work. Any tips on what I could do? Thanks in advance!

• 12.04 monitor brightness commands ignored

  - by jarvisschultz

  I cannot change the brightness of the monitor on a laptop either from the command line or from keyboard shortcuts. I have verified that the file in /sys/class/backlight/acpi_video0/brightness is changing. I have also verified that I am running the nvidia drivers. Things I have tried: Adding entries to /etc/default/grub The GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX entries now read GRUB_CMDLINE_LINUX_DEFAULT="quite nosplash acpi_backlight=vendor" GRUB_CMDLINE_LINUX="noapic" I have also tried various commands here (with an update grub and reboot each time) but nothing has helped I enabled brightness control in /etc/X11/xorg.conf so that it now looks like Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Investigated installing linux-kamal-mjgbacklight and determined it was not applicable to my system Nothing seems to have made any difference. I am using an Nvidia GeForce GT 330M with driver version 295.40. Does anyone have any other suggestions?

• Nautilus (File) 3.10.1 how to lock drag and drop bookmarks

  - by Davide Marchi

  From the new Nautilus releases exist the ability to create shortcut/bookmarks simply by drag&drop folder onto the nautilus left panel; However, this behavior can unintentionally create additional bookmarks if you are not very accurate when dragging files to bookmarks, especially by people with little experience in the use of computer. How is possible to disable the drag&drop bookmarks creation? Or ideally should be planning to implement the drag & drop mode only if you are running in conjunction with the press of a key on the keyboard ..

• suspend error on 14.04 LTS

  - by user1450663

  I've looked around and seems like various problems around suspend are wide spreaded for 14.04 release, nevertheless I haven't seen exactly my problem reported, nor my laptop model mentioned. So, the problem. When I press sleep button system seems to be going into suspend, i.e. screen goes black, it stops responding on the keyboard and wireless LEDs turn off, however the power LED doesn't go into suspend state and CPU fan also keeps spinning. But unlike the other problem described here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315435 when I close the lid and reopen it - system wakes up and goes back to normal locked screen state, so reboot is not needed. System details: This is a clean freshly installed Ubuntu 14.04, 32bit Laptop Dell D630 kernel 3.13.0-34-generic

• How do I disable auto-away for online presence?

  - by Will

  I am using Natty with with classic GNOME desktop. I use Empathy and sometimes Skype. Both these get the online state from the system itself somehow. If I don't touch my keyboard for a few minutes - even when watching a YouTube clip or something - the inactivity triggers an auto-away state on my messaging apps. It's synchronized so I imagine its coming coordinated from the system, and not the two apps making the same decision individually. How can I disable this? I want manual control - I'm only away when I set it to away in a messaging app.

• How to automount usb drive reliably without fstab

  - by user103279

  Hi I need a way to mount a usb drive without using fstab. I Cannot use fstab because the drive is not connected to my computer at boot. This causes an issue during any one off reboots because start up hang waiting for this device until a keyboard intervention to skip it. I cannot use my current script with just does mount /dev/sde1 /media/Backup because sometimes it changes to sdf. Consider this a server install. I can't use tools at the user or GUI level. I suppose the sum of my question is how to manually mount a usb drive from the commandline considering the reliability of the /dev/sd value isn't consistent. Thanks,

• How to have the game world get rendered on just a part of the screen?

  - by VictorB

  I am implementing a game on both Desktop and Android. The Desktop version will just rely on the keyboard to handle the user input on the game screen, whilst the Android one will have to have a set of buttons placed in a bar at the bottom of the game screen, using a Stage. Consequently, I am expecting the game world to take up the entire space available on the Desktop screen, whilst on Android it should expand to the entire width of the screen, and to the screen height minus the height of the buttons bar I've mentioned. What would be an appropriate approach of handling space sharing between the game world and the buttons bar? Thank you.

• Syanptics Touchpad Won't Re-enable

  - by user71607

  I disabled my Synaptics touchpad while a key on my keyboard and now I can't get it to work again. When I press that key again it says the touchpad turns back on but will not work at all. Rebooting doesn't help, and I tried installing touchpad-indicator but when I try to enable from there it says that it enables, but the icon remains like it's disabled. The odd thing is that it works on the lock screen so I know the drivers aren't messed up, it's just a setting. Also, the touchpad works on guest mode but still nothing on my account. I tried using gconf to set the touchpad_enable to true and it worked, it sure set it. Doesn't make a difference though, my touchpad is still useless. Terminal commands I've used: gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true synclient Touchpadoff=0 modprobe psmouse
