• Dual monitor working incorrectly on a Dell XPS 8300 with an AMD Radeon HD 6450

  - by John

  I have been having trouble with Ubuntu on my Dell XPS 8300 (Actual image of the desktop). I have heard that the AMD Radeon HD 6450 has trouble with Ubuntu, and I believe that it is the source of the problem (though I am no expert by any means). When I boot the computer and choose to run Ubuntu, on a rare occasion both monitors (I have an AOC and a Samsung) will display their correct desktops, however most of the time, one of the desktops will be shifted away from its proper position and awkwardly positioned on the screen (showing the login box in the middle/right etc). If anyone has any advice on how to fix this, that would be greatly appreciated.

• Getting the PC speaker to beep

  - by broiyan

  There has been much written on getting the beep sound from Ubuntu releases over the years. Example: fixing the beep My needs are slightly different in that I do not want to ensure sound card beeps are functioning. Instead, I want PC speaker beeps, the kind produced by the original built-in speaker because I believe they will produce less CPU load. I have confirmed that my computer has the PC speaker by unplugging the external speakers and shutting down Ubuntu. At some point in the shutdown and restart process a beep is heard even though the external speakers have no power. I have tried the following: In /etc/modprobe.d/blacklist.conf, turn these lines into comments: #blacklist snd_pcsp #blacklist pcspkr In .bashrc /usr/bin/xset b on /usr/bin/xset b 100 Enable in the gnome terminal: Edit Profile Prefs General Terminal Bell Ensure no "mute" selections in: System Prefs Sound various tabs (uncheck them all). Select "Enable window and button sounds" in: System Prefs Sound Sound Effects In gconf-editor desktop gnome sound, select the three sound check boxes. In gconf-editor apps metacity general select the audible bell check box. Still I get no PC speaker beeps when I send code 7 to the console via my Java program or use echo -e '\a' on the bash command line. What else should I try? Update Since my goal is to minimize load on the CPU, here is a comparison of elapsed times. Each test is for 100,000 iterations. Each variant was performed three times so three results are presented for each. printwriter.format("%c", 7); // 1.3 seconds, 1.5 seconds, 1.5 seconds Toolkit.getDefaultToolkit().beep(); // 0.8 seconds, 0.3 seconds, 0.5 seconds try { Runtime.getRuntime().exec("beep"); } catch (IOException e) { } // 10.3 seconds, 16.3 seconds, 11.4 seconds These runs were done inside Eclipse so multiply by some value less than 1 for standalone execution. Unfortunately, Toolkit's beep is silent on my computer and so is code 7. The beep utility works but has the most cost.

• How can I find which "command" corresponds to opening a gnome-panel menu, for use in a keyboard shortcut?

  - by Ryan Jendoubi

  There are many questions and answers here and around the web on setting basic keyboard shortcuts in GNOME. Most of them are either for launching applications, or Compiz settings, or for changing defaults for other things for which Ubuntu provides defaults shortcuts. What I want to know though is how to refer to a gnome-panel menu item in a custom keyboard shortcut. I'm using Ubuntu 11.10 with GNOME Classic, and the old GNOME 2 / Ubuntu 10.04 keyboard shortcuts for the main menus (Alt-F1) and the "Me Menu" (Super+S) don't seem to work. So my question is two-fold. Primarily I'd like to know how to set those shortcuts. But a second-order question is how I could have found this out myself: is there some program I can use to see what signals or commands are fired off when I click on various things, in this case gnome-panel menu items? I'm interested in the broader question because I've sometimes wanted to set shortcuts for specific menus or menu items in GNOME 2, so a way to find out what command I need there would be useful. Give a man a rod, as they say :-) I've had a look at a good lot of keyboard shortcut and menu related items here to no avail. One somewhat relevant question is this one, but it's just a "how do I do it" question, and applies to Unity, not GNOME, although it would be great if whatever investigatory method answers this question might also apply under different desktops, like Unity. The answer to this question is essentially how I was doing it in 10.04 / GNOME 2, although the questioner's query isn't exactly addressed - how to get directly to "Broadcast" with a key combination. Again, it would be great if an answer delving into how such menus work and how they interact with the rest of the system would be applicable to pinpoint menu items.

• How to convert an XFS file system to HFS+

  - by user219350

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but ! " Basically, I work on OSX-Mavericks 10.9.3, which sees very Windows 8.1 and works wonders with NTFS, but does not see Ubuntu! Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.

• I have installed ubuntu into my windows 7 64 bit, i am having problems with boot

  - by noob

  I have a problem I have not found any solution to, I am not so familiar with ubuntu commands or ubuntu in general. My problem started when I chose in windows 7 settings/ bootloader settings as ubuntu default, and it boots straight into grub, and in grub if I choose windows, it goes to the loader for half a sec, and goes straight back to grub. So I have disabled my windows 7 completely. And I have not found any way to boot back to windows, so I could go to settings and set it to windows... My only option seems to be re-installing the whole Windows 7...thus loosing all my saved games etc... I am fine using ubuntu for basic needs, but I am getting desperate here...

• Ubuntu 12.10 - Resolution stuck at 1024x768 using Open Source Radeon Driver

  - by mumble

  I'm using Ubuntu 12.10 with an ATI Radeon HD5670 card. I currently have the open source xorg-edgers driver. I've been using this driver interchangeably with the Radeon open source driver since fglrx seems to give me a lot of freezes. So I can't really use proprietary drivers, the Radeon driver seems to be stable for me, the resolution is the only problem. The resolution is stuck at 1024x768, where my monitor's native resolution is 1366x768. How do I enable that resolution? Going to System Settings Display only gives me 800x600 and 1024x768 by the way. And just another question, how do I know if xorg-edgers driver is enabled? When I run sudo lshw -c video, I still see the radeon driver. configuration: driver=radeon latency=0 Thanks a lot in advance!

• Headphones don't work on an Acer Aspire 5920g

  - by Dave Chatelain

  All the problems I read about were all about the sound not working when they plugged the headphones in. I have the problem that my mic will work but the sound is still played on my built-in speakers. When I look at the sound settings, it doesn't give me any options for headphones. I run 12.04 and never had this problem in Windows. I run it on a Acer Aspire 5920g. Any tips or ideas will be very helpful.

• Fail to start windows after Ubuntu 11.10 install

  - by user49995

  Computer: HP Pavilion dv7-6140eo OS: Originally Win7 I recently decided to try out Ubuntu, and I decided to dual-boot it with Windows 7. First I googled some how-to's, then I downloaded Ubuntu onto a memory stick and made a second partition (I originally only had one partition that I shrunk and used the unallocated space to install onto during the Ubuntu install). During the install I set format type to xt4 (or something, it was the default option), chose the "in the beginning" option and set the last option as "\". The install was successful. Although, when I restarted my computer I weren't able to choose which operating system to start; it went right into windows. After showing the windows logo for half a second before rebooting, I get a blue screen (see bottom of the page). Trying to fix it, I deleted the newly made partition I had just installed Ubuntu onto (seeing it wasn't working either). This made no difference. I proceeded with installing Ubuntu again, so I would at least have a functioning computer, and now Ubuntu works fine (on it now). The only difference on start-up is that I get a Grub window asking me to between several options including Linux and Windows 7 (loader). Now, if I choose Windows 7, I get the message "Windows was unable to start. A recent software or hardware change might be the cause". It recommends me to choose the first option of the two it provides; to start start-up repair tool. The second option being starting windows normally. If I start windows normally, the same thing happens as earlier. My computer does not have a windows installation CD. Although, it has (at least it used to, if I haven't screwed that too up) a 17gb recovery partition. In addition I made an image of the computer onto a external hard drive when I first got it. Though, I have no idea how to use either. If anyone has any idea how I can make windows work again or reinstall it (already backed up my files) it would be greatly appreciated. I still prefer to dual boot between the two functioning operating systems, but I will settle for a functioning windows 7. Thanks a lot for any replies. Blue screen: A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps: Check for viruses on your computer. Remove and newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configures and terminated. Run CMKDSK /F to check for hard drive corruption, and then restart your computer.

• Wireless very slow. Changed mode from Infracstructure to Ad-hoc

  - by Dan

  This is my first time using Linux so go easy on me :) I downloaded and installed Mint 11 couple of days ago and I was having trouble connecting to internet with wifi. Actually it says it connects but does not load any webpages. I tried to get help from this model of laptop owners (Asus G73SW) who uses mostly Ubuntu but they said they never had any problem right from install. So I decided to try out Ubuntu 11.04. Same thing. BUT now I get internet after going into Network Connection edit and changing the Mode from Infracstructure to Ad-Hoc. I get load pages but very slow. And if I'm not mistaken, as I was writing this paragraph, I might have been disconnected. However the wifi bar is full. Please help me this newb because I really want to keep using Ubuntu but I might just have to go back to W7 if nothing can be done. Thank you!

• How to modify grub entry for supporting KGDB kernel image?

  - by Nishant

  I am trying to update target m/c grub.cfg file for KGDB setup but while booting the m/c it got hung completely and not asking/waiting for remote gdb connection. Following is the entry which I added:- menuentry 'Ubuntu, with Linux 2.6.32-24-kgdb' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set 12878c3b-c553-4b4b-986a-6e32daea3ad1 linux /vmlinuz-2.6.32-kgdb root=/dev/mapper/ubuntu-root ro kgdbwait [email protected]/,@192.168.140.158/ quiet initrd /initrd.img-2.6.32-24-server } I have also compiled and copied /boot/vmlinuz-2.6.15.5-kgdb & /boot/System.map-2.6.15.5-kgdb to target m/c from devlopement m/c.

• How can I limit the number of open AF_INET sockets?

  - by Stefano Palazzo

  Is there a way to limit the number of concurretly open AF_INET sockets (only)? If so, how do I do it, and how will the networking behave if I'm above the limit? For background: My cheap commodity router is a bit eager to detect 'syn flooding'. When it does, it crashes (and doesn't automatically restart itself). I'm thinking limiting concurrent connections to around 1000 should keep it from bickering.

• Strange resizing of partition after reinstalling Ubuntu 14.04 64bit

  - by Mike

  I started with Windows 7 on 120GB SSD and Ubuntu 14.04 32bit installed on 60GB partition on separate 1TB HDD. I just did a fresh reinstall of 14.04 64bit on the 1TB HDD. In the installation set up process, I selected the second choice of "deleting Ubuntu 14.04 and all it's files,documents, photos etc and reinstalling" to what I figured would reinstall the 64bit OS on the already existing 60GB allocated partition. Instead, it reinstalled Ubuntu as 43.5 GB and created a separate 15.8 partition. So now it reads that my disk space for Ubuntu ( in settingsdetails) is 43.5GB (instead of the previous 60GB that my old 32bit had) The upside is I can now access my 1TB HDD from my toolbar(and all the files located on it) Before, I could only access that through Windows (I can also access the SSD too, but that was always the case) Both drives are mounted now. My initial reaction was to go into Windows 7 disk management delete the strange/new 15gb partitionextend the 43.5 to the unallocated space. But I'm not sure if this is necessary or would even work. My question is why did it create a 15gb partition shrinking my ubuntu disk space, and is it useful? I don't want wasted space, so before I go through all my set up of Ubuntu, should I change this. At this time my HDD reads as 43.5 partiton, 15.8 partition, and 874GB exfat32 (939GB total)

• Package dependencies cannot be resloved?

  - by Hayden Win

  i was in the ubuntu software center, and when i try to install something like OpenJDK, i get an error saying: Package dependencies cannot be resolved This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time. When i click on "Details" it shows this: The following packages have unmet dependencies: openjdk-6-jre: Depends: openjdk-6-jre-headless (>= 6b24-1.11.1-4ubuntu2) but 6b24-1.11.1-4ubuntu2 is to be installed Depends: libjpeg8 (>= 8c) but 8c-2ubuntu7 is to be installed Depends: libpulse0 (>= 1:0.99.1) but 1:1.1-0ubuntu15.2 is to be installed How do i fix this, and what's caused this problem in the first place?

• How to import a pdf in libreoffice? under ubuntu, all pages are blank

  - by Daniele

  I have some .pdf generated by a scanner, that I want to import in LibreOffice and do some small editing. The PDF has only one object per page, a page-size image. If I open it in LibreOffice under Ubuntu 12.10, it imports "successfully" but all pages are blank. I have the libreoffice-pdfimport package installed. That is true with both LibreOffice 3.6 (part of Ubuntu 12.10) and with 4.0.2, from libreoffice ppa. The same .pdf files open perfectly fine on both LibreOffice for Windows and LibreOffice for Mac (yes, I have three computers with all three OSes), but on Ubuntu 12.10, all pages are blank, so I can only conclude this is an issue with Ubuntu packaging, or something really weird prevents it from working under linux. How can I import these kinds of .pdf into LibreOffice for editing?

• Why is Lubuntu default desktop environment

  - by John

  So I just wanted to try things out on 14.04, so I did sudo apt-get install lxde sudo apt-get install lubuntu-desktop When I get to the greeter, it reads Lubuntu (Default) Lubuntu Netbook LXDE Openbox Ubuntu Why is Lubuntu default? I don't know if its because its the last thing I installed or if its because it is in alphabetical order. I'm tempted to test this theory by installing Xubuntu and see if it becomes default. I'd like it to read Ubuntu (Default) and have the Ubuntu splash instead. When I open lightdm.conf, there is no line "user-session" nor "greeter-session". They are missing. Is this normal and I have to add it manually?

• /etc/profile not being sourced

  - by Marc

  For 11.04, I did a fresh install of my system. Part of that install was to install rvm, which sticks a rvm.sh in /etc/profile.d/. This doesn't work as /etc/profile (which loads each +r in /etc/profile.d/*.sh) is not being loaded. According to the documentation, the profile is only sourced if bash is run in login. To verify this, I invoked bash --login, after which rvm was available. This has worked for me in previous versions of Ubuntu without any configuration. That is, a fresh install of 10.10 will correctly source profile/.d. My question is: is there anything I'm doing wrong, or are there some new assumptions being made in Natty that have broken this? My current workaround is to source /etc/profile in ~/.bashrc (which is awful as profile is meant to load before bashrc's, but does the trick).

  I just migrated from Wubi to actual dual booting Ubuntu and Windows 7 my machine is an Aspire 4750G. When I had (Wubi) Ubuntu 12.04 LTS 64-bit the network applet included the "enable mobile broadband" option. Now, I am using Ubuntu 12.04 LTS (32-bit) actual install as the 64-bit does not work. And my problem is that it does not show the "enable mobile broadband" option. This is so weird considering that I did not encounter the same problem in Wubi based installation.. Kindly help.. I have managed to connect to the internet via Sakis3G Script, still I find the previous method a lot more convenient..

• Terminal/Putty showing control characters (^M) after updating

  - by jaycee48

  I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.
