• How can I remove unmounted SD Card icons from my desktop?

  - by user75286

  I have been using some audio utilities in Ubuntu 11.10 to tweak .mp3 files on my phone (Motorola Photon 4G). I connect via USB... both my phone and the internal SD card are mounted as two separate drives. The SD card has an unusual drive name with some odd characters. When I'm finished, I unmount my phone (or "safely remove drive"), but the SD card can't be unmounted. I've mounted and unmounted my phone on 4 occasions now, and there are now 4 SD card drive icons that I can't remove from the desktop. I tried using the gconf-editor/apps/nautilus/desktop trick to make drives invisible and it's not working. Right-clicking on the icons and selecting "unmount" produced the following error message; (I can't type the unusual drive name characters... replaced with xxx) Unable to unmount xxx umount: /media/xxx is not mounted (according to mtab) How can I remove the unwanted icons from the desktop and is there a method for avoiding this problem in the future? Thanks!

• Evince 3.10 with menubar

  - by user43787

  I find that the 2 buttoms menu from the evince v3.10.0 are not really useful. Why did ubuntu NOT re add an menubar?. It would have been looking better in unity ! The unity top panel has enough space for an normal program menu. Here is an screenshot of what i mean: (The program works already in ubuntu 13.10 with unity or cinnamon fine. Some little compiler warnings but nothing more) Example in Cinnamon or in unity

• How to upgrade from 11.10 to 12.04?

  - by Marco

  I am using 11.10 and I really want to update to 12.04 but it's impossible. I cannot see it in the update manager (I did select the option for the releases). I tried sudo update-manager d, and sudo-apt get upgrade and sudo apt-get upgrade release d but nothing. And sudo do-release-upgrade is not working as well! (I get "no release found" message.) So finally I did put on a live USB and when I boot, I click on install, then it's telling me that I do have 11.10 and I can select for erase all and install Ubuntu 12.04 or I can install along 11.10 and the second option to update 11.10 to 12.04 is grey. I cannot selected it! Why? Am I running out of options? What else can I do to upgrade to 12.04?

• Broadcom 4313 Signal strength very low on an HP Pavilion dv4

  - by thegreyspot

  I have a HP pavilion dv4 4141US laptop running fresh ubuntu 11.10. This laptop has a broadcom 4313gn chipset for the network card. The network card is using the brcmsmac driver. Which, I heard else where on askUbuntu that its the best driver to be using for this card. I can connect to my network, however I have extremely low network signal. Right now I am right in front of the router, and I only get 72%. If i go to the room directly behind the router's wall, i get no signal, where as with windows 7 I get a nice 70% percent. UPDATE: I use WEP at home and an open wireless connection at work. Both have same result. Both are completely different routers. Also you G What can i do?

• sudo does not work in GUI after upgrade to 13.10

  - by Radim

  On 2 completely different machines I have the same problem after upgrading from 13.04 to 13.10: All programs/task requiering sudo permissions (software updater, starting synaptic, installing programs, shutdown) do not start / execute. No gksu (or other) window comes up. Synaptic never shows, software updater pops up with a "you are not allowed to perform this action" message. All programs / task work when started from terminal with sudo, like "sudo synaptics" asks for my password, starts and works as expected. I am in the admin group which is liked in sudoers config (verified with visudo and getent group admin). Some link from GUI to gksu (or similar) is broken. Please help! Radim

• Installing linux on OCZ RevoDrive3 x2

  - by user2101712

  First of all, here is the configuration of my computer: Motherboard: Asus H87Plus RAM: Corsair Vengeance 32GB Processor: Intel i7 4770 Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module) I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD): # modprobe dm_mod # dmraid -ay it says: no raid disks. And the following command: # ls -la /dev/mapper/ just shows /dev/mapper/control How can I install Ubuntu on my computer? what is the correct method?

• Ghosting Program for Ubuntu 12.10

  - by Sean Webber

  I am looking to figure out how to set up a mass backup system for a computer network (of about 25) and am looking for a ghosting program that makes an image of the entire system for backup/recovery purposes. While clonezilla would work.. you have to manually boot us the CD for it. I am looking for a program that runs INSIDE Ubuntu that sends a system image backup off to the network server at set times, then when needed could also be used to burn the clone back to the machine. Another words- automatically and the only time I have to do anything to it is when I need to burn a backup BACK to a 'crapped' machine. Any ideas?

  - by Waxolunist

  I have a Thinkpad X230. After a boot it hangs with checking battery state [OK]. A second boot is most times successful.

  - by Paul Connolly

  I am a Windows user trying to move over to Ubuntu without much success. I have installed the 11.10 version as dual boot by using Wubi tool on the Ubuntu website and can only use the operating system for about 5 minutes before it overheats and shuts off the machine. I have done my searches and seen many posts about overheating but cannot see one that I am able to apply to my particular case. Can anyone give me a steer on this please?

• Google Chrome on Ubuntu 12.04 not rendering webpages correctly

  - by sumit_gt

  I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem? PS: here's the output of lshw -c video: *-display description: VGA compatible controller product: Madison [Radeon HD 5000M Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi vga_controller bus_master cap_list rom configuration: driver=fglrx_pci latency=0 resources: irq:46 memory:e0000000-efffffff memory:f0020000-f003ffff ioport:d000(size=256) memory:f0000000-f001ffff Here's the output of lspci -nn: output of lspci -nn

• My application quicklist goes missing when using "quickly submitubuntu"

  - by Kazade

  I'm trying to submit my app for the app showdown, but I've just noticed that when I use the "submitubuntu" Quickly command, my dynamic quicklist entries don't work. I think this is because the desktop file gets renamed from tickit.desktop to extras-tickit.desktop I'm coding a hacky fix to look for /usr/share/applications/extras-tickit.desktop and changing the argument for get_for_desktop_id() if it exists, but is there a better way? Can I stop Quickly renaming the desktop file?

• Text box select issue

  - by Kent Boogaart

  I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

• Battery Power when running Ubuntu 14.04 LTS in dual boot

  - by Amro A.

  This is only a general question in order for me to get a better idea of my dual boot (windows 8 & Ubuntu) systems. I noticed that every time I run Ubuntu (which is becoming more often) the battery power gets consumed really fast. I am not performing any special tasks at the moment, just getting to know the system, for example, sound settings, watching videos, surfing the net and so on. When I do the same thing in Windows 8 the battery lives a considerable amount of time longer. Is this something to do with Ubuntu or is it because of the dual boot that I have going on? In other words, if I start running Ubuntu all by itself on my laptop, will it be more power consuming than Windows 8?

• Black login screen Ubuntu 12.04 if WGA cable pluged in on reboot

  - by Sulliwane

  I'm using Ubuntu 12.04.1, 64 bits, installed on a Z77 Pro4 (ASrock motherboard), crucial M4 SSD drive (sata 3), and intel i5 3570k (ivy bridge). I have this annoying problem : When I startup the computer, I get a CLI login prompt : At this moment, if I press enter, i get the usual CLI login prompt. If not, here is what I get : From now, if I login using CLI, i identify the lightdm processus, kill and start it : #ps -A | grep lightdm #sudo kill -9 1273 #sudo lightdm and miracle, these commands bring back the gui login screen. BUT It's very annoying as I have to repeat these steps at every boot, and the people using this desktop are not familiar with linux at all! So I tried to figure out the cause and here is what I found : If, when I shutdown the computer, the WGA cable is not pluged in, then Ubuntu will boot on GUI login screen without a glitch! But If the WGA cable is pluged in when shuting down, I will get CLI login prompt... Note 1: I installed linux kernel 3.4, but it hasn't solve the problem. Note 2: Is it linked to the new HD 4000 integrated graphic processor ? Note 3: If i boot on an USB stick (Ubuntu 12.04), NO problems ! Note 4: If booting on the SSD, when clicking "shutdown" button, the shutdown process never ends up (logout screen keep displaying and fans are still rolling). But if booting on USB stick, the shutdown action runs properly.

• Setting up multiple cores for apache solr for Ubuntu 12.04 and Drupal 7

  - by chrisjlee

  I'm setting up solr locally for my development purposes and integration with Drupal 7. I'm not very familiar with tomcat. My background has primarily been LAMP setups. So I went and installed the package provided by ubuntu for apache solr following this guide. sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples sudo apt-get install solr-tomcat I've got that working. The apt-get package manager does a great job and allows me to setup solr but with one core. What steps need to be taken to enable multi core setup for apache solr? And below is my solr.xml file: sudo nano /var/lib/tomcat6/conf/Catalina/localhost/solr.xml <!-- Context configuration file for the Solr Web App --> <Context path="/solr" docBase="/usr/share/solr" debug="0" privileged="true" allowLinking="true" crossContext="true"> <!-- make symlinks work in Tomcat --> <Resources className="org.apache.naming.resources.FileDirContext" allowLinking="true" /> <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr" override="true" /> </Context>
