• How do I make a Live USB without destroying my Windows computer?

  - by user71089

  Unlike every other post I have read, let me begin by saying that I am TERRIFIED of destroying my Windows 7 home system in the attempt of making a bootable Ubuntu Thumb Drive. I very specifically DO NOT want to attempt configuring a dual boot system. What I am seeking is a portable operating system on a thumb drive, through which I can run my COREL software via VirtualBox-4.1.16-78094-Win. I want to be able to use my own software on my work computer without any worries about screwing up the host system anywhere I go. Supposedly, I just made a bootable Thumb drive, having successfully loaded the ISO for ubuntu-12.04-desktop-i386 using Pendrivelinux's Universal-USB-Installer-1.9.0.1 However, all that I get is a Thumb Drive that wants to install Unbutu onto my PC's HDD. I am not finding any clear path to this end in the posts I am reading. Like it or not, Windows is a fact of life for me. The goal is to be able to use my software on my work PC without doing anything intrusive that will cost me my job. If I have a meltdown on my PC at home trying to make this happen, it will be nearly as bad. Is this even Do-Able? Can the process be made clear? Thank You, Ubuntu World ...!

• 5 year old ubuntu system, always dist-upgraded => ok. however some tasks remain

  - by knb

  I have a PC with a current ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kindof left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

• Touchpad issues on HP Pavilion dm4 (can't right click)

  - by Habstinat

  Can anyone help me with my touchpad issues? I have a HP Pavilion dm4 and it has two areas on the bottom of the touchpad to designate right and left clicks. This mostly doesn't work on Ubuntu in the fact that it recognizes any taps on either tap zone as a left click. Instead, I have it set so if I tap anywhere on the pad it makes a left click. There should be, and there are, many ways in the mouse configuration window to simulate a right click using only a touchpad. None of these work. Changing mouse orientation doesn't do anything, "dwell click" also does nothing, and, the oddest part of this problem, whenever I try to turn "Simulated Secondary Click" off (it doesn't work anyways, but just to try to toggle it), the entire theme of my desktop changes to a gray Windows '95ey look. The only way to get rid of this is to close and reopen the mouse preferences window. My computer is fairly new and the Ubuntu installation is less than a day old. I didn't do anything that I think could cause this. The problem is that I can't right click. Help, please?s that I can't right click. Help, please? Afterword: I installed two scripts from http://sansmicrosoft.blogspot.com/2010/10/pavilion-dm4-1160-erratic-touchpad.html . They didn't do anything I couldn't already do, and they did not make it possible for me to right click. :(

• Ubuntu 12.04 "stuttering"

  - by Totte

  When I log in to the desktop Ubuntu seems to "stutter". Doing pretty much anything causes the cursor to freeze for a few seconds, and the rest of the screen updates something like every 15 seconds (during these 15 seconds I can still move the cursor). For example, opening the home folder I first see no effect, followed by a semi-transparent home folder, and finally the folder as it should be (this can take like 30 seconds); no animation, just three individual frames. Also, I sometimes don't see a window for a program, even though the program in question is supposed to be "up". Since this is my first experience of Linux, I confess I have no idea where to start - searching the web I only found problems with complete freezes/crashes requiring rebooting, as opposed to this "stuttering". I installed Ubuntu 12.04 32bit from a bootable USB stick a couple of days ago, right after a fresh Vista 32bit install. Thinking the stuttering might stop if I updated Ubuntu, I managed to install approx 270 updates through the Update Manager, but the stuttering was still there. Apart from the updates, I haven't installed any software other than what was included on the bootable USB stick. Vista and Ubuntu are on a single Crucial m4 SSD, in a dual-boot setup, with GRUB. CPU: Intel Core 2 Quad Q6600 GPU: Nvidia GeForce 8800 GTX (with the recommended proprietary drivers) RAM: 2GB DDR2

• Smart Phones Shockingly Energy Efficient; Lead to Decreased Household Power Consumption

  - by Jason Fitzpatrick

  Given how often our smart phones and tablets spend plugged in and topping off their battery reserves, it’s easy to assume they’re sucking down a lot of power. Analysis shows the lilliputian but powerful devices are surprisingly efficient and may be decreasing our overall power consumption. Courtesy of energy-centric blog Outlier, we’re treated to a look at the power sipping habits of popular smart phones and mobile devices. The simple take away? They use shockingly little electricity over the course of the year–you can charge your new iPhone for a year of regular usage for under a buck. The more complex analysis? The proliferation of tiny and energy efficient devices is displacing heavier energy consumers (large televisions, desktop computers, etc.) and driving a more efficient gadget-to-consumption ratio is many households.

• Using Git with TFS projects

  If you having been following the updates to CodePlex over the last several months you will have noticed that we added support for Git source control. It is important to the CodePlex team to enable developers to use the source control system that supports their development style whether it is distributed version control or centralized version control. There are many projects on CodePlex that are using TFS centralized version control. But we continue to see more and more developers interested in using Git. Last week Brian Harry announced a new open source project called Git-TF. Git-TF is a client side bridge that enabled developer to use Git locally and push to a remote backed by Team Foundation version control. Git-TF also works great for TFS based projects on CodePlex. You may already be familiar with git-tfs. Git-TFS is a similar client side bridge between Git and TFS. Git-TFS works great if you are on Windows since it depends on the TFS .Net client object model. Git-TF adds the ability to use a Git to TFS bridge on multiple platforms since it is written in Java. You can use it on Mac OS X, Linux, and Windows, etc. Since you are connecting to a TFS Server when using Git-TF make sure you use your CodePlex TFS account name: snd\YOUR_USERNAME_cp along with your password. At this point, you will need to be a member of the project to connect using Git-TF. Resources Git-TF Getting Started Guide Download: Git-TF Git-TF Source on CodePlex

• How to Activate wifi in Toshiba Satellite C655?

  - by user4106

  I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

• How do I force the system to look for new sound devices?

  - by John Zeringue

  I have a small flat screen TV (Toshiba) that I often connect via HDMI to my laptop (an HP Pavilion dv4) and use as a computer monitor. When I do this, I prefer to use the TV's speakers, particularly when I'm watching video, because the sound quality is much better. However, when I connect the HDMI cable after turning on my computer (rather than having it plugged in before booting up), Sound Settings does not list the TV as an output device, and I am forced to reboot. I was curious if there is an easier solution to this, perhaps a CLI command to check for new sound outputs. Does anyone know of something like this or have another solution? To clarify, I believe this is a software problem. The HDMI always works, and I can switch my desktop over to the TV at any time. The issue is that, if the HDMI wasn't connected during start up, the TV will not appear as an output option in the Sound Settings GUI. So, unless I'm mistaken, my question is not HDMI specific, but rather a general usage question about manipulating sound settings from the command line.

• Network(ing) to the Limit

  - by Oracle OpenWorld Blog Team

   By Karen Shamban While Oracle OpenWorld attendees are networking, there's an Oracle Global IT team that builds and maintains the massive networks that help run the show. The objective? To keep things running as seamlessly and smoothly as possible, constantly evaluate priorities, mitigate risk, and be ready for whatever might happen -- because things do happen when there are 50,000 plus attendees, tens of thousands of devices, unexpected requirements, and a constant flow of up-to-the-minute information. Here's just some of what it takes to keep the conference going, network style: 100 Oracle network, voice, and desktop engineers; security, risk management, and other IT experts, who come in from 17 countries  1000+ network switches 300+ miles of copper and fiber 485 wireless access points 2,500 wired laptops 300 VoIP phones And just where are all these networks and devices deployed? This is what the team had to build and manage: Moscone North, South, and West, including: The keynote hall Oracle DEMOgrounds in the Exhibition Halls Hundreds of session rooms Connection Centers, Social Avenue, Lounges Registration The Howard Street Tent and Taylor Street Cafe tented venues Oracle Square (Union Square) Yerba Buena Gardens Masonic Auditorium Sessions and demos at 8 hotel venues That's a whole lot of networking going on. And here's the kicker: the team has only 4 days to bring get it all up and running across these many venues, and exactly 12 hours to take it all down once the show ends. The Global IT team puts in the equivalent of 152 24-hour days for set-up, 227 24-hour days of support during the conferences, and then tears it all down in about 20 24-hour days. And in case you were wondering, the planning for next year's Oracle OpenWorld starts ... next week. No rest for the weary.  Now THAT's networking!  So hats off to the Global IT team -- the job ain't easy, but somebody's got to do it, and they do it remarkably well.

• Will Ubuntu work out on my mother's computer?

  - by PleaseStand

  My mother had an old Compaq desktop computer running Windows 98, which she used for occasional Web browsing and playing cards. Recently, a relative brought up a newer computer; it ran Windows XP. Unfortunately, the hard drive failed soon afterward, forcing me to reinstall the operating system. Not having the original Windows disc or product key led me to consider Ubuntu Linux. Will it work for mom? Is the hardware compatible? (Check the history of this question for the full specifications.) Would Ubuntu/Xubuntu suffice, or would I be better off buying a new copy of Windows? Is her card game (Hoyle Card Games 3) likely to run on Wine? I believe the minimum system requirement is Windows 95. Failing Wine compatibility, is running Windows 98 on VirtualBox an option on such an old computer? Are there any equally good card games for Linux? She plays mainly Bridge, Poker, and Solitaire. Is there any "Large Fonts" option for those with poor vision? Is it possible to use a serial mouse?

• Screen refresh/display problem in Xubuntu 14.04

  - by user286328

  I have just installed Xubuntu 14.04 as a dual boot on a desk top (Pentium R 4 CPU, 2.66 GHZ, 2G RAM) running XP home edition. In some situations when in Xubuntu I am having what seem to be screen refresh problems. When I open File Manager or Settings Manager the text names of various apps display but most of the icons do not. Moving the mouse over an app name generally causes the icon to appear, but it often vanishes once the mouse pointer is moved. This issue occurs irrespective of the view setting. Icons appear fine in the menu that comes up when I right click in the desktop, and in the menu that comes up when I click the mouse icon at top left. What I suspect is a related issue. In Abiword text sometimes fades, disappears or does not display immediately when I type, or text of the whole document fades. It then comes back or darkens if I left click a few times on the text. If I scroll through a document the text often fades and may remain faded until I left click a few times.

• Ubuntu Not Waking From Suspend

  - by thenorm

  I'm running Ubuntu 12.04 (not wubi, usb install) alongside Windows 7 on my Toshiba Satellite Laptop Series L655D-S5050 I have a couple of issues, Ubuntu will not wake from suspend when closing the lid. It will show the Ubuntu screen then go to black and spit out some quick text before the screen will just flicker, as if trying to wake up. I've been googling around looking for a fix but nothing seems to help. Maybe it has something to do with the drivers? I checked additional drivers in the system settings, but it says there are no drivers present. Any ideas? Also, this issue isn't present all the time. But sometimes when I go to shutdown or restart Ubuntu, it will just loops to the login screen. Thank you, for any input or help! Also I can get some logs of these issues, but not really sure how to go about all of that. I'm not to familiar with ubuntu, as i've only been using the desktop version for a couple months now.

• How should a team share/store game content during development?

  - by irwinb

  Other than Dropbox, what out there has been especially useful for storing and sharing game content like images during development (similar feature set to Dropbox like working offline, automatic syncing and support for windows/osx)? We are looking into hosting our own SharePoint server but it seems to be really focused on documents... Maybe Box.net would work? EDIT For code, we are using Git. To be more precise, I was looking for an easy, automatic way for content produced by artists/audio engineers to be available to everyone. Features like approvals of assets don't hurt either. Following the answer linked by Tetrad, Alienbrain looked pretty interesting but..is way out of our budget (may be something to invest in in the future). What ended up doing... We were going to go with Box.net but downloading the sync apps for desktop use required us to wait to be contacted by them for some reason. We did not have much time to wait so we ended up going with Dropbox Teams. Box.net has a nice feature set but we never really felt held back without them. Thanks for the help :).

• How can I activate a Panel-icon via a script (or get its screen co-ordinates; to click it)?

  - by fred.bear

  This question is in the context of Lucid 10.04 desktop (ie. no Unity). I do most screen navigation via the keyboard (not the mouse), so I'm looking for a script solution to re-activating an app which has been "minimized" to the Panel's Notification Area. I'll use Skype as an example. wmctrl allows me enough access to normally-minimized windows, but when Skype is "minimized" to the Notification Area, it simply goes "off the radar" as far as wmctrl is concerned. Bearing in mind that icon positions in the Notification Area can vary, is there some way to determine the screen co-ordinates of Skype's Panel icon, so I can "click" it using xdotool (or a similar utility)? ...or maybe there is a more direct way to activate the "dormant" Skype? ... (and I don't mean the mouse ;) Here is the script, so far. Hopefully it will make clear what I'm trying to do: #!/bin/bash procname="skype-wrapper" windmask="Skype™" if [[ $(pgrep -x -n -c "$procname") == 1 ]] ; then wintitle="$(wmctrl -l |grep "$windmask" |head -n 1 |sed -n "s/^.\+${HOSTNAME} \(.*\)/\1/p")" if [ "$wintitle" = "" ] ; then echo "Click on Skype's Panel-icon to show the main window" ############################################################### # How can I find the screen co-ordinates of Skype's Panel Icon ############################################################### else # Skype is running, and has (at least) one visible window which matches $windmask. Activate it. wmctrl -a "$wintitle" fi else # The process is not currently running. Start it. ("$procname" &) fi

• Release Notes for 5/18/2012

  Here are the notes for this week’s release: Pull Requests We’ve added the ability to see the snippets of code where a user commented inline in the discussion of pull requests. You can also add another line comment directly from the discussion area, rather than navigating to the code diff viewer. Note that there’s currently a known issue where the line associated with the comment isn’t being properly differentiated for existing pull requests (the line in the middle of each diff preview should be bolded). Apologies for the inconvenience! As part of this work, we also took some time to clean up our diff viewer UI to remove the dots and introduce a new color scheme where green is used for added lines. Bug Fixes Fixed an issue affecting the ability to assign pull requests. Fixed an issue where managing various team resources for a project was not working in Chrome or Firefox. Fixed an issue where a project’s RSS subscribe dialog popped up in the wrong place. Fixed an issue where editing wiki anchor links would insert extra characters, resulting in broken links. Fixed an issue where project logos did not display correctly when browsing the site with https in Chrome or Firefox. Fixed an issue where users could encounter errors when deleting remote Git branches. Fixed an issue affecting the ability of fork collaborators to push changes to the fork. Fixed an issue where the advanced work item filters would not persist when navigating through result pages. Fixed an issue where the issue tracker notifications link was not clickable in Chrome. Fixed an issue where pull request comments with line breaks would not be formatted properly when viewing the pull request. Other We upgraded our Git servers to version 1.7.10.1.

• Can't install GTX 680 drivers on 12.04

  - by user68945

  I recently installed Ubuntu 12.04 on my desktop. I have three monitors, and after installing, ubuntu only detected one at 1080p. I downloaded the driver from the nvidia website, but when I stop lightdm and try to run the driver, it gives me an error message: ERROR: Unable to find the kernel source tree for the currently running kernel. Please make sure you have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems, for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option. I tried instead to install the driver via the terminal, with the X ppa. The installation seemed to work, but when I rebooted, my display was at 640x480 resolution, with no other options for resolution. The NVIDIA X Server settings program is there now, but when I run it, it simply tells me that I don't seem to be using their driver, and that I should run nvidia-xconfig as root. Doing so doesn't help, I simply get the same issue again. I checked the file at /etc/X11/xorg.conf, and it's an NVIDIA file (has nvidia in the header). Does anyone know something else I can try? EDIT: Forgot to mention, I tried installing drivers via the "Additional Drivers" GUI utility, there were two options, one of them marked "(post-release updates)". I tried both of them, in both cases it tried to download and install for a while, then said that there was an error, and that a description could be found at /var/log/jockey.log. Both logs were over 700 lines

• Mouse selects everything on its own

  - by meneer

  I have a strange problem that my mouse keeps selecting everything I point to. For example, if I open Rhythmbox, then at the top of the screen there is a text which says which song is playing. If I move my mouse over this text, then it will select this text; but I am not clicking. This behaviour does not happen in all programs. For example in Firefox I have no problem at all. Maybe it is Gtk related? Nautilus also behaves strangely; I cannot open files by clicking on them, I have to select and make a box around the file and then press enter to open it. If I click, then nothing happens. Similar problems also happen with other Gtk software. I think the problem might be related to touchscreen issues (I have a touchscreen). I run Gnome 3 on Ubuntu 12.04. I have a HP touchsmart 610 desktop computer. Any help is greatly appreciated. UPDATE: I just did a fresh reinstall, and I am 90% certain that it is related to the touchscreen drivers. Here is what happens when I reinstall. At first boot, so exactly after install, everything works fine, except the touchscreen: The touchscreen does not respond. I update ubuntu, because I installed from an old CD (CD with ub. 12.04). Then on next reboot I have touchscreen working , but the working touchscreen comes together with the mouse selecting everything on its own. SECOND QUESTION: Would anybody know how I could figure out what those touchscreen drivers are (so that I can disable them) ?

• Now that Apple's intending to deprecate Java on OS X, what language should I focus on?

  - by Smalltown2000

  After getting shot down on SO, I'll try this here: I'm sure you'll all know of Apple's recent announcement to deprecate Java on OS X (such as discussed here). I've recently come back to programming in the last year or so since I originally learnt on ye olde BASIC many years ago. I have a Mac at home and a PC at work and whilst I have got Windows and Ubuntu installed on my Mac as VMs, I chose to focus my "relearning" on VB first (as it was closest to BASIC) and then rapidly moved to Java as it was cross platform (with minimal effort) and so it was easiest to work on code from both OSes. So my question, if the winds of change on Mac are blowing away from Java and in this post-Sun era, what would be the best language to focus my new efforts on? Please note, this isn't a general "which language is better?" thread and or an opportunity for the associated flame-war. There's plenty of those and it's not the point. I realise that in the long term one shouldn't be allegiant to an individual language so, taking this as an excuse, the question is specifically which is going to be the most quick to be productive on given the background whilst bearing in mind minimum portability rewrites (aspiration rather then requirement) and with a long term value of usage. To that I see the main options as: C# - Closest in "style" to Java but M$ dependent (unless you consider Mono of course) C++ - Hugely complex but if even slightly conquered, then a win? Is it worth the climb up the learning curve? VB.Net - Already have background so easiest to go back to but who uses VB for .Net these days? Surely if using a CLI language I should use C#... Python - Cross-platform but what about UI for the end-user? EDIT: As a usage priority, I envision desktop application programming. Though the ability to branch in the future is always desirable. I guess graphics are the next direction once basics are in place.

• PHP hosting some info required [closed]

  - by mtk

  I have recently given a control of newly bought hosting space and the domain account. There is a technical team from the hosting site to help out with problems, but that is a long process, i.e. log a ticket, wait for a long time, and I don't get the correct answer in the first shot. I was wondering, if anyone has any helpful guide and how one must go with hosting a site. Any info that must be know w.r.t to cpanel? Any other useful stuff if any one has, or could point me to ? Just to give a few difficulties: The same php code working well on local machine, giving error on remote as "File not found". The file is present indeed as I have ftp'ed all the files correctly. session_start error are outputted to html page with warning "Header already sent". and many more technical things, that work well on local but not on actual hosting server. So, if anyone has any helpful stuff in this reference, as to what all changes are required or what a programmer must be aware from a hosting perspective, please let me know. Note I am hosting a PHP site with mysql db, on a shared environment.

• No wubildr, No spaceleft, Boot Error and A previous installation was detected in D:\ubuntu. Please uninstall that before continuing

  - by tdc2bdc

  At first I was downloading Ubuntu 12.10 using Windows Installer, but I cancelled it after just 2-3 minutes and dowloaded 32-Bit ISO (ubuntu-12.10-desktop-i386). Then I created bootable USB Stick (new HP 210 v210 w) using Pendrivelinux (Universal-USB-Installer-1.9.1.4). I Formatted D Drive. (Both by Windows & EaseUS) I've set boot priority correctly. But after getting message "Boot Error", I ran wubi.exe directly from USB drive. Now the message is "A previous installation was detected in D:\ubuntu. Please uninstall that before continuing." I formatted D: again and performed disk check, surface test using EaseUS. It shows no error or bad sectors. Formatted & checked my pendrive too. Directly ran .iso. But same error keeps coming. I found way around above problems, by copying extracted .iso on D:\ and installing Ubuntu using wubi.exe and though on boot it was shown with Windows 7, selecting it caused following error Try hd(0,0): NTFS5 : No wubildr Try hd(0,1): NTFS5 : So, I uninstalled it and Reeinstalled it Now installation fails at around 7mins saying " An error occurred. No space left on device. For more info please see log file " My D: is a 9 GB partition. (99% Free) Ubuntu Site 12.10 says it needs around 4.5 GB. Now Trying it by extendin D: to 10 GB... Got No wubildr. Please help. tdc2bdc

• Cannot find GRUB - Ubuntu/Windows 8 dual-boot

  - by ubeatlenine

  Hello Ubuntu community, I find myself in an interesting situation. I have a Dell Inspiron 531 with Windows Vista. Recently my brother decided it would be a good idea to overwrite Vista with the Windows 8 consumer preview. Since we have had this PC for a very long time, we have long since lost the Vista CD, and according to the Windows 8 preview website you cannot recover your previous OS without it. I thought this would be a good opportunity to try out Ubuntu (since we obviously cannot keep the preview as an OS), but it appears that Ubuntu 11.10 Desktop is not compatible with Win8. Ubuntu doesn't run from the LiveUSB I made, instead it freezes on the loading screen and then disintegrates into black and white stripes. I blamed this failure on Ubuntu not being compatible with win8 yet and tried to install Ubuntu from the USB on a partition made from the remaining space on my hard drive - about 100GB. However the installer crashed while loading modules and told me I didn't have enough disk space. Since then, I have not been able to load either Ubuntu or Windows, BIOS is shifted over to the left of my screen, and I always get the same message: error: unknown filesystem grub rescue> typing "ls" at the prompt gives me the following: (hd0) (hd0,msdos7) (hd0,msdos6) (hd0,msdos5) (hd0,msdos2) (hd0,msdos1) does this mean I have multiple partitions running windows on my computer? Is it possible to recover Vista without the disk? Are all of my problems stemming from Ubuntu not being compatible with Win8 preview? (I realize the majority of my questions are about Windows, but seeing as the prompt I get is for grub I thought I would ask here first.) Any insight anyone has on this predicament would be greatly appreciated.

• I deleted all files and folders (including hidden) from /home/username/ now in big trouble

  - by jeffery_the_wind

  I am logged into a remote ubuntu server, and I accidentally erased the entire /home/username/ directory for the current user. The only thing left is a hidden directory called .gvfs. I don't need anything of the Documents/Music/etc. Now it is not letting me cd into the /var/www/ directory, which has permissions 666 and it is owned by the current user. I am afraid to disconnect from my ssh session because I don't know if I will be able to get back on. Have I permanently created a problem? Is there a way I can replace the most important files to the /home/username/ directory? Thanks! ** EDIT ** Thanks everyone for the help. I figured the problem with cd into the /var/www/ was actually my permissions in the /var/www/ directory. It was set to 666, changed it to 755 and everything was good again. It doesn't look like anything systematic was ruined by deleting the contents of the user folder.

• Delete Ubuntu and Grub from PC (and BIOS unaccessible)

  - by Temitope

  I've really done a mess while upgrading 12.04 to 12.10, or my PC did, or ubuntu did, I can't really tell. The situation now is I have a dual booting machine, Windows 7 and ubuntu 12.10 -When turning on the PC, I can't access boot options, I've tried every thing, esc, f1 f8, f10 (I have a Hp pavilion) but all I can see is a short-lasting screen with three lines reading something like "error:files not found" or "link not found". So the PC turns to the Grub loader screen. This is already a BIG problem. It means I can't change boot order, and I'm diperate, since it doensn't seem that repairing my operating systems will bring my BIOS back. -If I chose Ubuntu in grup, it loades but then frezes on the desktop, I may be having problem with unity3d, or compiz, which was reported to be crashing the first times I started ubuntu. Now, after turning off and on the pc several times, no crash is reported again. Ubuntu just load my background image and nothing else. Not the side menu, not the header, nothing. Althogh the system seems "functioning", when I press the power button on the PC, for example, the normal shutdown dialog window appears. -If I chose Windows, Grubs tells me that something is not found, and to press any key to continue; I do it and then Windows loads perfectly. What I now want to do is 1- use EasyBSD to change boot order and boot Windows partition first 2- delete the ubuntu partitions from within windows disk manager What I except happening is that My PC turns to, or near to factory booting settings: I press the power button and Windows loads without asking me nothing I have acess to all my hardisk from withing windows Is that what will really happen? Are there danger I'm not seeing? What I don't except happening is The BIOS access key return functioning How could I eventually solve this? I would like to reinstall Ubuntu, 32 bit version this time.
