• 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,

• Dual boot w/ windows 7

  - by Aduff

  So my PC had windows XP and Win 7 on it and I went into the XP partition and installed Ubuntu 12.10 over it being sure to use 90% of the XP partition for the / mount and 10% for the swap. It installed but when I boot the computer it doesn't give me the option of choosing between 7 or Ubuntu, just booting right to the Linux distro. Should I have installed it in 7 over the XP partition? I can see the drive in Ubuntu that contains all the 7 files. How can I recover my 7 access?

• What is the sudo password after I deleted the password for the user?

  - by Ubuntunewbie

  To have an easier access to the computer I deleted the user's password so it is blank. But now I'm still asked to type in a password for sudo actions such as installing programms, etc. I know that this belongs to Ubuntu's outrageous security policy (which is why I use Ubuntu in the first place..) but I don't have any password to enter any more!! The old user password is not accepted and anything else (like just hitting enter) doesn't work either. I already tried the recovery mode (root shell) way passwd USER< but it replied that it can't access the password or it has no authority. Thanks in advance for your help!

• How to work on my personal ideas during the weekend? [closed]

  - by nurne

  I'm working full time 5 days a week, mostly between 10 and 14 hours a day. In the end of the day I'm very tired and just wanna take a shower, hang out and go to sleep. I have a lot of ideas that I want to implement and someday sell maybe through an online software business. I have my weekends free. However, when I get to the weekend I can't even imagine myself turn on the computer. But I really want to make my ideas happen, and I can't leave my job right now to devote myself only to my ideas. What do you say? Do you find some method helpful? Do you use some technique? Thanks

• In 12.04, with my Linksys WUSB54G USB adapter I can see the networks, but cannot connect to any of them

  - by tobye

  I recently loaded Ubuntu version 12.04 onto my computer, and I have a WUSB54G v4 USB wireless adapter. I first tried to get it to work by simply plugging my adapter into an open USB port. This seemed to work fine, it came up with a list of wireless adapters, so I clicked on the correct one and entered the security code. It looked like it was going to connect. It tried for about five minutes before I stopped it. I then decided to create a network as I also have one setup. I did this and it connected, only one problem, I couldn't get onto the internet. Please help me, I am new to Ubuntu and am totally lost.

• External Hard disk not workng on windows after I formatted it on Ubuntu

  - by nav_jan

  I formatted my Western Digital 500 Gb hard disk on Ubuntu 10.4 and now I want to use it on Windows 7 but it cannot detect it. I formatted it with FAT(applicable to all) option. I tried to Google this problem a bit and as suggested by one of the site i tried to format this drive with NTFS. Still windows cannot detect it. Drives in windows 7 is not a problem because I tried a different usb drive on it and it works. I can see the led of the drive glow when I connect it and I can also see remove drive safely option in lower right corner, but i cannot see any option in "my computer" to access the hard disk. I am new to Ubuntu. Any help is appreciated.

• Monitor screen size and programming ease

  - by rrazd

  I recently heard that a big part in successful/quick debugging and easing the process of programming is to use a big screen. I may be purchasing a new computer in the future and this has me wondering: 1)Is the aforementioned statement actually true or is it a bit of a stretch? 2)Have you noticed that this plays a significant enough part to buy a bigger screen if the bigger screen is significantly more expensive? 3)Is it common for developers to work on 13'' laptop screen as their main (and only) workstation (this is what I currently develop on) or is this actually disadvantageous? This may be subjective but any professional opinions/experiences would be greatly appreciated!

• Sound not working

  - by Jason

  I am new to ubuntu, but really enjoy it. I do have one issue with setting it up on my computer. It is a GoBook XR-1 and everything works perfectly except there is no sound. I've searched and tried everything that I can think of, even uninstalling ubuntu and trying Windows to see if the speakers worked. I found out that it wasn't the speakers or any hardware issues. I tried to download the Realtek drivers, but still no success.

I want to totally remove my 12.04 and do a clean install of 12.10, i created a live USB then i restarted my computer to boot from USB, i got the following error: Product is covered by one or more of the following patents: US5,434,872, US5,732,894, (and many more) Under that i see: PCIe GBE Family Controller Series v2.38 Media test failiure Exiting PXE ROM And then it reboots I've searched a lot for an answer, i guess the problem is with something in my bios, but i didn't find a fix. I would really appreciate a fix for my problem. My laptop is a Toshiba p775 dual boot ubuntu 12.04 and windows 7.

• Ubuntu 12.10 doesn't boot (installed with wubi)

  - by Luna Kiyiya

  Quick and simple, my ubuntu doesn't want to load after installing with ubuntu. Starting the computer, at the screen to choose your operative system, first shows an error that windows failed to start, and later asks me to choose between ubuntu and windows. If I choose ubuntu, the same error happens again and I return to the same screen. If I choose windows, windows just starts normally as it was doing before I installed it. How can I solve this?? Thank you for your attention... I really need some help :)

• f12 and ctrl + f5 not working correctly [migrated]

  - by ComatoseDuck

  When I came back to my work computer after being away for a week I found out when I try to clear the cache and refresh the page via ctrl + f5 (or just f5) I get the prompt "Type the Internet address of a document, and Internet Explorer will open it for you" with a drop down list in IE. When I try f5 in Chrome and FF it opens the "Open file" dialog box. When I try to f12 for Dev tools in IE, Chrome & FF it opens up the print dialog box. Why is this happening and what can I do to revert it back to the way it was?

• NetworkManager refuses to manage my WLAN interface

  - by user104167

  I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

• Unable to change desktop environment in 12.10

  - by LEOXD

  I upgraded to 12.10 some days ago and now I'm unable to change between the environments. I currently have GNOME 3 (with extensions), KDE and, of course, Unity installed. The computer is a Lenovo G550. In the login screen I can get into the menu where the DEs are listed, but I can't select one. I can't use a test account of mine, which used GNOME 3, because after I logged in X crashes/restarts. Unity works, but I can't switch from the broken GNOME 3 to Unity. What did I broke during the upgrade and how can I fix it?

• C# .NET 4.0 interactive course?

  - by Kanyhalos

  I would like to learn C# programming. I already studied it for several weeks and wrote some minor programs with VS2010, and I'm not completely newbie at programming because I worked on STALKER - Shadow of Chernobyl as scripter, but it was LUA. I want to become a real programmer. I think C# is a decent way to start with. I already learned about the most commonly used resource sites and got some nice eBooks as well, but unfortunately I don't have time to sit down in front my computer all the time, so my progress is pretty slow. I would like to ask that if someone can recommend me some decent interactive online courses to make my learning progress faster. I know about the "joe grip" course but I don't know if it's worth $39 also it's only for .NET 1.x and 2.0 while I'd like to learn 4.0 so I have no idea what should I do.

• How can I disable as much "flair" as possible in Unity?

  - by UlfR

  I'm running Ubuntu 11.10 from a fresh install on a somewhat aged computer, so I have some speed problems. But since I do want to use the new cool way to work with things that Unity introduces I do not want to fiddle with getting another desktop environment. My idea is to disable as much flair as possible, but there are tonnes of options that I do not understand or have the time to read up on when I launch CompizConfig Settings Manager. Which of these could safely be disabled? Are there other places where performance could be gained by disabling things? So how can I make the whole thing a little more snappy?

• Can you run OpenGL 2.0 on modern machines?

  - by thePalindrome

  I'm looking to get into 3d with OpenGL, using SDL to help with other stuff. I found plenty of good tutorials (lazyfoo is a big one), but "Learning Modern 3d Graphics Programming" uses a newer version of openGL that I'm not able to run! I opened up OpenGL extensions viewer, and I can only run OpenGL 2.0, whereas most tutorials are in higher versions. I ask this because I've heard that just about everything in 2.* got depreciated in the newer versions, so I'm worried that my code might not work. I'm looking at a few other tutorials, but I'm so used to SDL that those just confuse me... So should I bother trying to do graphics programming now, or should I just wait until I can upgrade my computer?

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• Wireless mouse temporarily freezes when resume from standby

  - by R Pennese

  I have been getting a very annoying problem since recently in Ubuntu 12.04, probably due to another update that did more bad than good... When I resume from sleep on my Lenovo Thinkpad T420, my wireless laser mouse (Logitech M705) freezes at regular intervals (15.20 seconds) for 5 seconds then works again. This happens regardless if the computer is on battery or on AC power. How do I debug this? I am getting tired of the fact that my system gets more and more unstable over time while it should be the opposite...

• Cant install Ubuntu. How do you format a Windows HDD

  - by heldeman

  I have an HP 630, and would like to install Ubuntu. All goes well until the point where you have to choose how you want Ubuntu installed. I choose on the whole HDD, I want Windows off the HDD. I press enter and about 5 seconds later the CD tray open and the computer reboots. This happens over and over. How do I format this Window HDD completely to install Ubuntu 13.04. I have tried 3 different CD's and the same thing happens each time.

• I can't log into my ubuntu 12.04

  - by user292674

  When I try to log in on my Ubuntu 12.04 it goes to a black screen ( of logging in checking stuff ), and says Checking battery ----- [ok] ( I'm using a computer instead of a laptop ) and just goes back to the login screen. Two days before I executed the command sudo startx trying to start KDE, but it didn't work. And after logging off and trying to log in again, I had this problem. A big problem is that I don't have internet connection at home. What should I do?

• How can I fix a shaky touchpad cursor in Ubuntu on my hp pavilion laptop?

  - by Vindiggity

  I recently installed Ubuntu 12.04 on my laptop and it works great, except after the initial reboot my touchpad cursor shakes violently when I hold my finger completely still on the pad.It works fine with a regular mouse plugged in. I couldn't find much scouting around the internet except that it might be that my touchpad doesn't have any dead zones? I am very new to Ubuntu and am fairly computer savvy, but I don't know a lot about using the terminal or anything like that, so if you could dumb down a fix for this as much as possible for me, I'd greatly appreciate it.

• xset: unable to open display

  - by user287878

  for the longest time after about 5 minutes my screen would blank out. Now the screen will go blank after 5 minutes but then 2 seconds after that it will light up white and keep the laptop backlighting on. I didnt change any settings to my knowledge it just happened randomly after powering it on one day and has occurred since then. I wish to resort back to blanking the screen out completely since i leave this computer on all the time and its hard to sleep with a huge white light all the time. "xset dpms force off" just yeilds me ---- xset: unable to open display ""

• 12.04 Login gone wrong

  - by Mark H

  I seem to have a fault in the login procedure somewhere. When I boooted up I found that if I selected Guest I could use the computer. If I selected my administrator account I was taken straight to the terminal. So I opened a guest session, went to user settings, and unlocked my admin account (it accepted the password!), and amended it to show "password None" and automatic login. I now find that when I boot up I am taken straight to the terminal - if I exit terminal I get the login screen - if I select the administrator login I go back to terminal - if i select guest I can use the PC, and if I select mu normal user account I can use the PC. So I cannot login as an administrator - so admin functions such as update are no longer accessible. Sorry to be so long winde but I am stuck. Can anyone suggest anything - I am a beginner with this
