• Blank screen when "boot from USB"

  - by Nathan

  OK so, here is what I have done: I downloaded the iso "ubuntu-12.04-desktop-amd64" I used "Universal-USB-Installer-1.9.0.0" to make a bootable USB I restart PC and change the boot option to USB HDD I get the menu to: Boot from USB Install to Hard drive Help etc When I click Boot from USB or Install to hard drive, loads of text flies past and then I get a blank screen and I cant see anything? What can I do so I can see the installation screen? Im using a dual monitor setup from my GFX card and my main display is on my HDMI port to my TV.

• Launcher disappears when Focuswriter is minimized

  - by Andreas

  This bug has to do with the integration of the full-screen writing app Focuswriter within Unity. It appeared before I upgraded from Ubuntu 12.04 to 12.10 - probably caused by a an automatically upgraded change that persist in 12.10: When I minimize Focuswriter after it has been in full-screen mode the launcher is invisible - instead of seeing it I just see a rectangle the color of my desktop background where it should have been. The launcher becomes visible if I click the area once but then I'm likely to hit an icon and unwillingly open a program. I've reported the bug to the developer of the program here: https://github.com/gottcode/focuswriter/issues/101 He has labeled the bug "upstream" saying that the bug is can only be fixed in Unity. My questions are: 1) does anyone (perhaps experiencing problems with other full-screen programs) have a solution or workaround so the launcher won't disappear? 2) where can I file a bug report for this problem?

• xrdp setup over ssh

  - by Xianlin

  Here are the steps to install xrdp on ubuntu 12.04 and get it working: http://www.ubuntututorials.com/remote-desktop-ubuntu-12-04-windows-7/ However, I want a secure xrdp connection over ssh and I am able to achieve it by using port forwarding in the software putty as below: L1234 == localhost:3389 But I am still able to remote login to the ubuntu through xrdp connection when I am not connected using SSH. It is supposed to deny remote login when SSH is not present. In the file /etc/xrdp/xrdp.ini I tried to change the [global] section by adding "ip=127.0.0.1" and it didn't work.

• How to disable Gnome-Shell auto-open in Dashboard

  - by user48027

  I am personalising my Gnome-Shell in Ubuntu 11.10 I would like to disable the feature to open the Gnome's Dashboard when I close the last Window in a Workspace. Edit to clarify: The dashboard is available only in GNOME Shell. The dashboard opens if you press the windows key (aka SUPER) or if you move the mouse to the upper left corner. If you close the last window of a workspace, but there are open windows on other workspaces, the dashboard opens automatically. The latter behaviour is annoying if you do not want to use the dashboard to open new windows or to change workspace. There are many ways to to both (Gnome do, Docky, keyboard shortcuts, clicking on something on the desktop, ...). Edit: There is a related Q&A, which was closed because the asked the same question for Mint: How can I prevent the activity view for opening when I close the last running app?

• Nautilus only starts as root user

  - by user7978

  Hello. I am running Ubuntu 10.04 64-bit. When I attempt to start Nautilus from the command line, it does not appear -- although a PID is generated. As root/sudo, I can start Nautilus fine. One note: I run e16 as the windows manager, so I do not use Nautilus to draw my desktop. However, even under this configuration, Nautilus used to run fine as a "regular" user. The permissions for Nautilus are the same as the other packages in /usr/bin. I believe this is a Gnome issue, but I'm fumbling at this point.

• Reinstall Ubuntu on Custom Partitions

  - by Forerunner117

  I am attempting to reinstall ubuntu 13.04 without losing my installed software and /home docs. I have read countless threads on this same topic, but nothing seems to apply to my situation. When I originally installed, I had created a separate partition for /home, but I am now unsure of which partition that was. Based on the picture below, where should I be installing the new copy? Also, will I run into problems since I am now running 13.10 and want to put 13.04 back on it? Should I grab 12.04 or 13.10 for this reinstall? Picture: http://i.stack.imgur.com/FL2SY.png (Note: I am performing this reinstall due to a complete muck up of my unity/compiz settings and configuration, resulting in no desktop. I've done my best to resolve this problem first before resorting to this.)

• Gnome 3 freezes when switching workspaces

  - by Bill Cheatham

  I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?

• Installing Ubuntu Server 11.04

  - by Jackson Walters

  Trying to install Ubuntu Server 11.04 on an 64-bit AMD machine. The install goes fine until after "Loading additional components", then I get a blank purple screen with a responsive cursor at the bottom. I've looked everywhere and can't find anything (all the documentation seems to be on the desktop version). I have a wireless card installed if that makes a difference, don't why it would. This happens regardless of whether nomodeset is set. Here's what it looks like (as described): Specs: CPU - 64-bit AMD Sempron 140 @ 2.7Ghz RAM - 1Gb DDR3 1333 HDD - WD 500Gb 7200RPM SATA 3.0Gb/s Mobo - Foxconn M61PMP-K Wireless Card - Rosewill RNX-G300LX

• How to fix LibreOffice 3.5 to start from launcher icon?

  - by Bucic

  Recently I installed LibreOffice 3.5 from debs (including the ones for desktop integration. Since then it behaves in a weird manner. Basically it won't launch from launcher shortcuts. Example: dash libreoffice launched (launcher shows with 2 seconds delay) 'keep in launcher' LO closed the LO icon on the launcher clicked pulsating for 5 seconds, then stops LO didn't launch I didn't look for open processes or anything and... dash libreoffice launched immediately without problems It also didn't remember recently opened items, but now it got fixed somehow. Other symptoms: - icon on the launcher and all menu categories appear with a delay of few seconds - two writer icons appear on the launcher What I did: used 3.4.5, uninstalled, installed 3.5 RC3, problems started to occur uninstalled RC3 'clean' per http://wiki.documentfoundation.org/Installing_LibreOffice_on_Linux#Debian_.2F_Ubuntu_3 installed 3.5 stable which is identical to RC3 still same issues I don't know if it is related but I use Unity test PPA:vanvugt/unity which I needed to solve the stuttering windows bug. Any ideas?

• How can I repair a corrupt kernel if no others are installed?

  - by Willi Ballenthin

  I've been running Ubuntu 10.04 on my laptop for quite some time. When I went to boot it up this morning, BAM! kernel panic (which immediately lead to human panic) when loading the kernel. So I've spent much of the day troubleshooting, and my current theory is that the FS is fine, but that the kernel image may be corrupt. Let's go with this current theory for the sake of this question, as I am interested how it is done. How can I replace the kernel image if I have no bootable kernels? Can I boot to a 10.04 live CD, copy the the vmlinuz-2.6.3x... to the HD and go from there? Wouldn't I want to copy the initramfs as well, but configured for the desktop system? Can I generate this from the live CD?

• How much C/C++ knowledge is needed for Objective-C/iPhone development?

  - by BFree

  First, a little background. I'm a .Net developer (C#) and have over 5 years experience in both web development and desktop applications. I've been wanting to look into iPhone development for some time now, but for one reason or another always got side tracked. I finally have a potential project on the horizon, and I'm now going full steam ahead learning this stuff. My question is this: I haven't done any C/C++ programming since my schooling days, I've been living in managed land ever since. How much knowledge if any is needed to be successful as an iOS developer? Obviously memory management is something that I'll have to be conscious about (although with iOS 5 there seems to be something called ARC which should make my life easier), but what else? I'm not just talking about the C API (for example, in order to get the sin of a number, I call the sin() function), that's what Google is for. I'm talking about fundamental C/C++ idioms that the average C# developer is unaware of.

• Boot splash broken by "SP5100 TCO timer: mmio address 0xyyyyyyy already in use"

  - by mogliii

  I have ubuntu 11.04 with all the latest updates. I have an ATI HD 4350 graphics card and the "ATI/AMD proprietary FGLRX graphics driver" activated. The reported behaviour does not affect the functionality, its just an optical thing. When I booted up using the desktop CD, the ubuntu boot splash was shown correctly in high resolution. Now after installation with FGLRX the dipsplay is broken (see picture). http://img824.imageshack.us/img824/7269/tcotimer.jpg This is what can be found in dmesg [ 8.621803] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01 [ 8.621967] SP5100 TCO timer: mmio address 0xfec000f0 already in use [ 8.622650] fglrx: module license 'Proprietary.

• How to control fan speed and temperatures on Asus A8Js laptop?

  - by Azeworai

  I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

• Mouse pointer hides at bad times after updating to 13.10

  - by Richard

  A bug, I think, though I can't even seem to find any information when searching for it. The mouse pointer hides itself, but it is still possible to use it. Whenever I start watching a video in VLC, or start playing KSP through Steam my mouse pointer disappears. It is not returned upon exiting the application. I have not tried with other games in Steam. The mouse pointer do not disappear when watching videos online through YouTube, though it properly hides itself after a few seconds. The bug came about after I updated to 13.10, it was not present with the same setup in 13.04. I have tried removing ~/.compiz and restarting the kernel module psmouse. Going to tty1 and back to the desktop reveals the pointer, though this fix is bothering me. How do I fix this problem?

• How to do pre-loading

  - by Dave

  I have a question that is confusing me with making a game. For my game launch i pre load everything for the main menu then i loop the game to display it. But lets argue player wants to launch a new game or a specific level, then you preload the relevant sounds/graphics for that level right? How ever, the player must already be running the game loop if they are at the main menu, so you can't load in the game loop or you will load every frame...but im pretty sure most big games don't preload every level when you first run the game from desktop because it would take a long time on some of these games.... How is it done :S

• Are Intel HD 4000 graphics supported on Ubuntu 10.04 LTS?

  - by user1118764

  I have an intel Core i7-3700 system with Intel HD 4000 integrated graphics with a dual monitor setup (1 connected via VGA, the other via DVI) on Ubuntu 10.04 LTS 64bit. I'm trying to get my monitors correctly detected. Right now, in only 1 unknown monitor is detected with a max resolution of 1280x1024, which is lower than my main monitor connected to DVI. Also, the desktop is mirrored rather than extended. I've previously managed to get a Core i5-2400 system with Intel HD 3000 integrated graphics with the same dual monitor setup and Ubuntu 10.04 LTS 64bit to work using the glasen ppa drivers, but this time, after installing them following the instructions How do I install the Intel HD 3000 video driver? but it doesn't seem to work. Does the Intel HD 4000 require a different driver from the 3000? If so, where can I get it?

• Various crashes in 12.04 after upgrade and fresh install

  - by stefan

  Ubuntu drives me crazy. Since I upgraded from 11.10 64-bit to 12.04 Ubuntu crashes regularly. One time the crash report tells me that Skype is the faulty app, another time it was Opera, and today the crash report tells me Xorg crashes. I read that it can be caused by a faulty upgrade so I made a clean new installation of 12.04 32-bit. But the error is the same. I had a look in the log files with a friend but we did not find a answer. This morning the crashes happened like this: Boot Auto-start Thunderbird Start VLC for radio Start Opera Working a while (30 minutes) Starting Skype 2 minutes later, the system freezes, the monitor turns black, a login screen appears and I enter my password. The desktop comes up again and the crash report pops up.
