• Can't boot after recent system update

  - by Ron

  Dear all, After recent system update (I think I saw something kernelish but don't really remember) my Ubuntu becomes unbootable. When I select "Ubuntu" from the boot menu, I'm greeted by a GRUB console and I don't know what to do (typing help shows some helpful commands for gods, unfortunately I'm a mere mortal). I'm doing this on Windows XP now. How do I go back to the future? Edit: The Ubuntu was installed using WUBI

• Unable to connect to wireless internet(wifi) through KDE plasma desktop

  - by Mohammed Arafat Kamaal

  I installed the KDE plasma desktop through Ubuntu software center. I am on Ubuntu Lucid Lynx. After the install, Im unable to connect to my wifi connection in the KDE session. But I can connect to my wifi perfectly through GNOME session. I've tried a lot without much success. Also KDE doesn't store my password correctly and keeps prompting for authorization again and again. Some of the things that I noticed. Network is detected, Network name and strength is also displayed. Other characteristics also appear properly. When the credentials are supplied, it accepts them and continually displays the message "Setting network address". However this process never succeeds. At this stage the password is repeatedly asked many times but the connection is never established. Some of the other things that I did, I have also tried other things like restarting my modem and the computer. That didn't work. I tried to restart nm-applet and KNetworkManager. That didn't work either. ifconfig display all my interfaces and Mac addresses correctly. Since its working fine GNOME the drivers are fine. This is sure a KDE specific issue. Other threads related to this on the interwebs don't offer much information either. Please share a solution for this.

• How to make bash quit tab autocompleting hidden directories

  - by Kristopher Micinski

  Most of the time, I don't need autocompletes for my hidden directories. In fact, that's the point of them being hidden! However, annoyingly, bash takes these directories into account when considering tab autocompletion. This is particularly annoying when I have the following scenario: a .svn foler along with a single folder that I want to traverse into by simply pushing tab. (This typically comes up with deep Java packages...) Is there any way to change the default behavior? Worst case scenario I have to type '.' before tab, which seems like a no brainer for my usability.

• Using the AccountsService API with Python

  - by pabluk

  I'm writing an application for the Ubuntu app showdown and I try to read/write the user's profile picture using this >>> from gi.repository import AccountsService, GLib >>> current_user = GLib.get_user_name() >>> user = AccountsService.UserManager.get_default().get_user(current_user) >>> print user.get_icon_file() None >>> print user.get_user_name() None But apparently does not work. Is there another way to use AccountsService with Python? I could not find more documentation about AccountsService and Python.

• How to inhibit suspend temporarily?

  - by Zorn

  I have searched around a bit for this and can't seem to find anything helpful. I have my PC running Ubuntu 12.10 set up to suspend after 30 minutes of inactivity. I don't want to change that, it works great most of the time. What I do want to do is disable the automatic suspend if a particular application is running. How can I do this? The closest thing I've found so far is to add a shell script in /usr/lib/pm-utils/sleep.d which checks if the application is running and returns 1 to indicate that suspend should be prevented. But it looks like the system then gives up on suspending automatically, instead of trying again after another 30 minutes. (As far as I can tell, if I move the mouse, that restarts the timer again.) It's quite likely the application will finish after a couple of hours, and I'd rather my PC then suspended automatically if I'm not using it at that point. (So I don't want to add a call to pm-suspend when the application finishes.) Is this possible? Any advice would be appreciated. Cheers. EDIT: As I noted in one of the comments below, what I actually wanted was to inhibit suspend when my PC was serving files over NFS; I just wanted to focus on the "suspend" part of the question because I already had an idea how to solve the NFS part. Using the 'xdotool' idea given in one of the answers, I have come up with the following script which I run from cron every few minutes. It's not ideal because it stops the screensaver kicking in as well, but it does work. I need to have a look at why 'caffeine' doesn't correctly re-enable suspend later on, then I could probably do better. Anyway, this does seem to work, so I'm including it here in case anyone else is interested. #!/bin/bash # If the output of this function changes between two successive runs of this # script, we inhibit auto-suspend. function check_activity() { /usr/sbin/nfsstat --server --list } # Prevent the automatic suspend from kicking in. function inhibit_suspend() { # Slightly jiggle the mouse pointer about; we do a small step and # reverse step to try to stop this being annoying to anyone using the # PC. TODO: This isn't ideal, apart from being a bit hacky it stops # the screensaver kicking in as well, when all we want is to stop # the PC suspending. Can 'caffeine' help? export DISPLAY=:0.0 xdotool mousemove_relative --sync -- 1 1 xdotool mousemove_relative --sync -- -1 -1 } LOG="$HOME/log/nfs-suspend-blocker.log" ACTIVITYFILE1="$HOME/tmp/nfs-suspend-blocker.current" ACTIVITYFILE2="$HOME/tmp/nfs-suspend-blocker.previous" echo "Started run at $(date)" >> "$LOG" if [ ! -f "$ACTIVITYFILE1" ]; then check_activity > "$ACTIVITYFILE1" exit 0; fi /bin/mv "$ACTIVITYFILE1" "$ACTIVITYFILE2" check_activity > "$ACTIVITYFILE1" if cmp --quiet "$ACTIVITYFILE1" "$ACTIVITYFILE2"; then echo "No activity detected since last run" >> "$LOG" else echo "Activity detected since last run; inhibiting suspend" >> "$LOG" inhibit_suspend fi

• Wireless with WEP extremely slow on an Acer Timeline 4810T with a Centrino Wireless-N 1000

  - by noq38

  I've upgraded an Acer Timeline 4810T to Ubuntu 11.10. Everything works fine except for the darn wireless interface (network manager). I just tested the wireless interface over a non-encrypted signal and it works beautifully. The issue is definitely related to WEP. Unfortunately, some of the networks I need to connect to are WEP encrypted, therefore this is a serious issue for me that is preventing me from using Ubuntu on my laptop. This was no problem in 11.04 and prior. Is there a simple solution for this? Any suggestions? Here's more hardware information. Hopefully this helps to debug the network issue: sudo lshw -class network *-network description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 00 serial: 00:1e:64:3c:5e:e0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-13-generic-pae firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:d2400000-d2401fff lspci 02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no Many thanks for your help!

• Why is Gnome-Shell thinking my "d" key minimizes all windows?

  - by Limitless

  I am on Ubuntu 12.04 LTS (in gnome-shell) and I am unable to use my "d" key. Regular gnome-2 works perfectly fine, but for some reason I cannot use my "d" key in gnome-3. I recently installed it and have been trying to figure this out, but I have no clue what's going on. I attempted to disable the keyboard shortcut that minimizes active windows, but that did not work. (My only option right now is to use CTRL-V to paste my "d"s.) On top of this, my arrow keys automatically move my windows and I cannot move through text using them. What's going on here, folks?

• What is better Ubuntu Tweak or Ubuntu Software center?

  - by S B

  Ubuntu Tweak has served me very well over the past few release cycles, but there seems to be more and more of an overlap between Ubuntu Tweak and the Ubuntu Software Center. I wanted to know whether these two great apps are headed for a head-to-head crash (which would be a shame for the Ubuntu community) or is there some way for the two projects to complement each other, integrate and make my favorite distribution even better? Happy new year to everyone.

• How to restore .bashrc

  - by Miranda Webb

  Terminal shows this bash: /home/atlas/.bashrc: line 73: syntax error near unexpected token `[' bash: /home/atlas/.bashrc: line 73: `if [ -x /usr/bin/dircolors ] ; then ' I've tried to fix it using "cp /ect/skel/.bashrc ~/" And I get this "cp: cannot stat `/ect/skel/.bashrc': No such file or directory" I'm unsure of why this is doing this and how to fix it. I had previously been in the bashrc file messing around and apparently I've messed something up. All I want to do is restore the bashrc file to factory settings.

• Mounting with Nautilus works but fstab gives "Host is down" error?

  - by Annan

  I'm connecting to my university's VPN so I can connect to the network drive. The VPN seems to be working fine and I can connect to the drive by typing the address into Nautilus and entering my login details: smb://139.___.___.140/home However, this fstab entry doesn't work: //139.___.___.140/home /media/___ cifs domain=CS,username==___,password=___,uid=sai,gid=sai 0 0 Nor does manually mounting it: sudo mount -t cifs //139.___.___.140/home /media/___ -o domain=CS,username=___,password=___,uid=sai,gid=sai,user The only error it gives is: mount error(112): Host is down Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) It's obvious the host isn't down since I can view the share from Nautilus. Why is Nautilus mounting it fine but not the normal mount command? What could cause this error?

• Deleted some files from home folder

  - by narendra shah

  I have recently installed Ubuntu for the first time in my life. So I am fairly new to it. I have deleted some files from my home folder. But now the problems have started. The system volume automatically reduces to zero. Further, as soon as I restarted my system, my panel settings we restored to default. When I right click in my home folder, it gives an option of 'restore missing files' but I am not able to restore them. Please guide me how to restore them. Thanks Narendra

  I am trying to compile some OpenGL apps from sources but there is no /usr/lib/libGL.so, or /usr/lib/libGL.so.1 or even /usr/lib/libGL.so.1.2. However fglrxinfo says: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc.

• Read Only usb stick that won't let me do anything to it

  - by Jonathon

  Somehow I messed up and accidentally made my usb stick into a read only file system. I have tried a bunch of things to delete the files, including the basic (rm -f myfile) and attempting to allow writing (sudo chmod +w myfile) and then deleting, but none of this seems to work. Any ideas on what I can do. I don't have anything on the usb stick that I need, but I don't want to throw away an otherwise perfectly good piece of equipment. How can I make it work? Am I going about this completely the wrong way?

• How does the PPA fit into the scenario of publishing an application to the Ubuntu Software Center?

  - by Mridang Agarwalla

  I've been going through docs for the past couple of hours but I haven't understood what the PPA is? I have a cross-platform Java application that I'd like to publish to the Ubuntu Software Center. My application is open-source and I'm using Github. Apparently, publishing applications to the store isn't as simple as uploading a deb package - am I right? I need to create an account on Launchpad and put all my code there. I don't intend to move from Git to Bzr merely for the sake of publishing to the app store but luckily, one is able to set up source-code mirroring from Github to Launchpad. Since my application is still very premature, it'll have updates fairly often. When I build my application on my machine, do I simply go my Ubuntu App Developer page and upload the new DEB package or do they build my application from source? What exactly is the PPA for? I don't think I'll need too many of the Launchpad features so I'd like to stick to Github if possible. (Publishing for Ubuntu really isn't trivial. I can see why there are so many developers out there who haven't published their applications to the Ubuntu Software Center. Publishing an Android applications has been the easiest so far.)

• Unity 3D (with Nvidia driver) becomes very slow and laggy

  - by Graham

  How can I prevent my Unity 3D desktop from becoming slow after a while, given that I have an Nvidia Quadro NVS 290 graphics in TwinView mode? The desktop starts out fast on login, but becomes slow / lagging / hesitant / high latency after a while, symptoms being spikes in CPU usage by /usr/bin/X whenever I cause any graphical activity with the mouse or keyboard (e.g. typing, changing tabs, dragging windows). The desktop remains slow even with all windows (except htop in Terminal) and extraneous processes killed. Detail: Changing tabs in Terminal takes about a second, and X spikes to 76% CPU. As I type into Firefox, X spikes to 95% CPU. Dragging Termiinal window, X goes to 70% CPU. Basically, every graphical action sends CPU usage of X through the roof. Device: Nvidia Quadro NVS 290 Driver package: binary driver nvidia-current-updates (280.13-0ubuntu5) Dual Monitors: Pair of DELL UltraSharp 1908FP in TwinView (X screen 2560x1024) OS: Fresh install of Ubuntu 11.10 amd64 Desktop with all updates. Hardware: Dell Precision T5400 Workstation Pastebin of Xorg.0.log Pastebin of xorg.conf Pastebin of nvidia-xconfig -t output (easier to read than xorg.conf) Output of /usr/lib/nux/unity_support_test -p: To obtain the following htop screenshow I typed "asdf" several times in in this text box, alt-tabbed to Terminal and took a screenshot of the high X CPU usage. This also happens when firefox is not running: Quadro NVS 290 has "No" thermal sensor according to sensors-detect: Next adapter: NVIDIA i2c adapter 0 at 2:00.0 (i2c-0) Do you want to scan it? (YES/no/selectively): Client found at address 0x50 Probing for `Analog Devices ADM1033'... No Probing for `Analog Devices ADM1034'... No P robing for `SPD EEPROM'... No Probing for `EDID EEPROM'... Yes (confidence 8, not a hardware monitoring chip) I tried the nouveau driver by disabling the nvidia-current-updates under Additional Drivers, but Ubuntu and xrandr -q fail to detect the second monitor. This may be issue 737349. Funniest thing is that Nouveau wiki says that XRandR 1.2 dual-monitor is supported so it should work with a second monitor.

• How to create list of installed packages for remove after testing?

  - by Wolf F.

  I like to test kmymoney. When trying to install there are a lot of kde packages that are needed by this program. That's ok, I'm using Unity and there are no kde packages installed at this moment. So, when I like to remove all this packages after testing kmymoney, how can I do that? sudo apt-get install kmymoney >> /some/folder/kmymoney.txt gives me the output of apt-get, but that's not what I'm looking for. Is there a way to remove this packages properly? Thanx in advance W.

• AFP and SAMBA shares are confusing my MacOS X Lion

  - by Pierre

  I've setup my file server running ubuntu 12.04 with AFP/Avahi and Samba shares. Simple configuration, nothing too complicated. I've given my AFP machine a different name than %h to avoid confusion when looking into my Finder. However, my mac os lion mbp still confuses the two and the only way to access the AFP shares is via direct connect to IP address. The samba machine name seems to be hardwired to hostname (I can only see that that workgroup can be changed). Is there anything I am missing or obvious that I need to set? Best regards and thank you in advanced Pierre

• What units does the ntp drift file use?

  - by arielf

  When the ntpd daemon is running, the file: /var/lib/ntp/ntp.drift gets updated periodically. Example: 17:20 hostname 118 ~> ls -l /var/lib/ntp/ntp.drift -rw-r--r-- 1 ntp ntp 7 May 20 16:46 /var/lib/ntp/ntp.drift # So it looks like it was last updated ~34 minutes ago The file has one number in it, for example, looking at a 4 virtual hosts, I find these values, respectively: -22.086 -10.214 -13.669 6.045 I assume these are seconds per day(?), but not sure. man ntpd mentions a different drift file /etc/ntp.drift which doesn't seem to exist. The man page doesn't explain what units are being used for the drift. Questions: Is /etc/ntp.drift actually /var/lib/ntp/ntp.drift on Ubuntu? What units is the drift expressed in? Thanks!
