• Ubuntu running like mud, system hangs and looks like its running at 3FPS

  - by user240803

  the system specks: AMD XP 3200+ 1GB DDR 333 RAM 160 GB HD IDE NVIDIA FX 5500 AGP Video Card Compaq Presario sr1230nx the system takes forever to boot and when it does it runs like total mud, reminds me of an overloaded system that has too many windows open or something... fresh install tried soo many thing like new memory (it had 512 stick) a new video card (onboard 8mb sis sounded like the problem, but wasn't... has gotten a little faster now but not by much) tried to disable all the things on the motherboard that could be, with no help... this machine runs windows XP, 7, and 8 JUST FINE!!! I mean for a single core CPU WIN8 runs AWESOME!!! BUT I already have a Gaming Desktop that has Windows 8 pro I want a Linux machine to get some time in and learn a few things... I want Ubuntu because of the Software center so I can install things I want until I am familiar with the command line.. I've worked on Computers since I was 12 I remember some of the DOS commands but I guess these are a little different... anyway any ideas? Ive also tried both drivers for the NVIDA card and that didn't help either... its not the card since it did this with both the NVIDA card and the SIS onboard... it also does this on live mode with the USB so I don't think its the HardDrive... I'm running out of options of hardware to try... I know this version of Linux works cuz Ive booted it on other machines and it ran great... what is with this Compaq? here is a vid of exactly what its doing... let me know if you need anything else I am right by the comptuer tonight so ask anything... http://youtu.be/-P-XNo81098

• GeForce and Radeon: what is present condition of opensource and proprietary drivers?

  - by Septagram

  So, it'm about to buy a fresh videocard. Since I do most of my stuff on Linux, I wonder how well will either videocard perform. I recently had a good experience with GeForce 6600 with proprietary drivers and a less than satisfactory experience with Radeon 9000 a while ago. From my experience, proprietary drivers for GeForce used to work very well, while proprietary drivers for Radeon failed miserably. And opensource drivers were sloooow. A few months ago I found out that ATI opened their specifications, and a work on fully featured opensource driver is in progress. I prefer to use free software whenever possible, with the exception of games, so, if that driver is fast enough, feature-rich enough and reliable enough I'd very much like to try it out. I wish I could say that if I can just to basic things, like watch video, heavily use compiz and work with simple applications, this may be enough. I do most of my gaming under Windows anyway. However, there is a good chance I'll go into indie game development in a few months fulltime, so it should also be able to run not-so-very-demanding games (say Nexuiz). But if it isn't, I'd like to know, what to expect from proprietary drivers. Do recent proprietary drivers from NVIDIA and ATI work well? Are ATI drivers just as easy to install on Ubuntu as are NVIDIA drivers?

• New XAML-Based User Group started in Birmingham, Alabama.

  - by mbcrump

  I’m pleased to announce that a new XAML-Based User Group has started in Birmingham, Alabama. The group is being hosted by Michael Crump and Jonathan Marbutt. The reason is very simple: we feel that Birmingham needs a fresh start. We are both very passionate about .NET and are hoping to share our experiences with the community. We have created a site (http://allaboutxaml.net) and our first meetup is now scheduled. We are here to discuss all things that have to do with xaml. This includes Silverlight, WPF, Windows Phone 7, Surface, Lightswitch and Silverlight with SharePoint 2010. We: believe strongly in xaml and are passionate about what we talk about. believe in an open-forum. believe a user group should be FUN as well as educational. do not claim to be an expert on anything, we are here to share. record every presentation and put it on the web for others to benefit. meet monthly but are flexible on the actual date. do our events outside of technical colleges. have families and our meetings start and stop on time. welcome new speakers. welcome adult beverages. Our first meeting is going to be on February 15th, 2011 (6PM), at Logan's on HWY 280. It is going to be more of a meetup than a meeting. I would like to discuss current xaml-based projects that you are working on and get to know one another. If you are interested in coming then please sign up here so that we know how many to expect. Please visit our site to find out more about us: http://allaboutxaml.net.

• In virtualbox, I can't access the dvd drive to install a guest host

  - by user211062

  I have installed a fresh copy of Ubuntu Server 12.04 and VirtualBox 4.3. I have set up a VM called "MediaServer" and tried to start it. I then get the following error: Cannot open host device '/dev/sr0' for readonly access. Check the permissions of that device ('/bin/ls -l /dev/sr0'): Most probably you need to be member of the device group. Make sure that you logout/login after changing the group settings of the current user (VERR_ACCESS_DENIED) I have looked all over the Internet and have been unable to find a solution. Using Webmin, I tried changing the group settings so that my user name was in the "vboxusers" group, but that did not work either. I tried various other changes in group settings and none of them worked. Also, I tried rebooting the server after the changes and that didn't work either. I have been following a guide on how to set up an Ubuntu server from the website "linuxhomeserverguide.com" and when it came to the section where you could finally set up your first virtual machine, I am stumped. I would really appreciate it if someone could help me. Thanks in advance.

• How to add display resolution fo an LCD in Ubuntu 12.04? xrandr problem

  - by SeregaI

  I am fresh for Ubuntu and Linux in general. I have installed Ubuntu 12.04 and stuck trying to setup correct resolution for my LCD display. The native resolution for the LCD is 1920x1080 here is the output from xrandr: $xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Then I create new modeline: $ cvt 1920 1080 60 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync So far so good. then I create new mode using xrandr: $ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync But for some reason that new mode was created for VGA (VGA1) output instead of LCD output (LVDS1): $ xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) 1920x1080_60.00 (0xbc) 173.0MHz <---------- ????!!!!!! h: width 1920 start 2048 end 2248 total 2576 skew 0 clock 67.2KHz v: height 1080 start 1083 end 1088 total 1120 clock 60.0Hz So, if I try to add mode to LVDS1, I get an error: $ xrandr --addmode LVDS1 "1920x1080_60.00" X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 25 Current serial number in output stream: 26 Adding that new mode to VGA1 works fine, but I don't use that VGA1 output.

• Laptop power button not working

  - by DyP

  I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install. Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press. Here some more information, please ask if something more could help: Power button is recognized as a device: xinput lists Power Button as a slave keyboard at /dev/input/event1, and I can run a tool to listen to that device and invoke some action (successfully). But using .config/openbox/lubuntu-rc.xml to assign some action to XF86ShutDown or XF86PowerOff does nothing. Works well for any key of the keyboard. xinput --test reports a keycode (key press, key release) of 124 when pressing & releasing the power button. xmodmap -pk lists 124 mapped to XF86PowerOff which seems correct to me (btw: is this the same as XF86ShutDown?) When assigning another keysymname to the 124 keycode, e.g. 'w', still nothing happens when pressing the power button (no window seems to receive a 'w'). Works well for any key on the keyboard. The outputs of xev for a press/release of the power button irritate me: MappingNotify event, serial 41, synthetic NO, window 0x0, request MappingKeyboard, first_keycode 8, count 248 FocusOut event, serial 41, synthetic NO, window 0x2a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 41, synthetic NO, window 0x2a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 41, synthetic NO, window 0x0, keys: 93 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (instead of 93, I also get different values) I might have missed something very basic since I'm not very familiar with both openbox/lubuntu and the X input system. Btw.: same goes for three other special buttons on my laptop..

• Why is my disk full?

  - by Agmenor

  I installed Ubuntu 12.04 by doing a fresh install where there was previously Ubuntu 11.10. My computer warns me now that my disk is nearly full. After having run apt-get purge, run apt-get autoremove and emptied the Trash can, I still have this problem as shown by this screenshot of Gparted: The disk /dev/sda7 is indeed full. I ran the Disk Usage Analyzer (Baobab) and I am still not sure of what is happening: One of my hypothesis is that when installing Ubuntu 12.04, I didn't configure my disks well and the disk /dev/sda6 is not mounted well as /home. Is this the reason indeed? What should I do to verify this and then to get the things fixed? Here are a few additional details to answer the questions I received (thank you everybody): My home directory is not encrypted. The Backup utility (Déjà Dup) is not set for automatic backups. (I do it myself and manually.) After I mount /dev/sda6, the command df -h gives Filesystem Size Used Avail Use% Mounted on /dev/sda7 244G 221G 12G 96% / udev 3,9G 4,0K 3,9G 1% /dev tmpfs 1,6G 904K 1,6G 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 164K 3,9G 1% /run/shm /dev/sda6 653G 189G 433G 31% /media/8ec2fa69-039b-4c52-ab1b-034d785132a1 (sorry but formatting this into code does not work, for an unknown reason) Thanks to izx's post, I realized /dev/sda6 was not even mounted before. It contains all the documents I used to have when I was running Ubuntu 11.10.

• Random touchpad and keyboard freezes on new 10.10 installation

  - by ancaleth

  My touchpad and keyboard freeze up on my newly installed Ubuntu 10.10. I was using Ubuntu 10.4 via wubi before on this Laptop where this problem never occurred. (I did not migrate wubi or upgrade to 10.10, it's a fresh start. 64-bit on Dell Studio, plenty of RAM, plenty of free space on partition etc.) I can't say there is a pattern yet, once it happened during the download of packages with the Update Manager, once it was just using Firefox, no other program running. I was forced to shut down manually. In between these crashes the laptop was booted once, updates were installed etc., firefox was used and there weren't any problems. Both crashes should be in the attached kern.log and I noticed there were some error problems before the last crash (at the end, obviously). It seems the wireless was experiencing problems. This wasn't noticed on the user end, since the touchpad + keyboard were already frozen. kern.log: http://paste.ubuntu.com/552617/ How can the freezes be fixed?

• Copy Ubuntu distro with all settings from one computer to a different one

  - by theFisher86

  I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out. On the source computer run dpkg --get-selections > installed-software and backup the installed-software file Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory. Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/ Then I'm going to run dpkg --set-selections < installed-software Followed by dselect That should install all of my apps for me. I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here. I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...

• LAMP setup - phpmyadmin says the mysqli extension is missing (but its listed in phpinfo)

  - by WebweaverD

  I regularly set up virtualbox ubuntu setups to run as local webservers. I have set these up several times and never had an issue. Recently I have been cloning them but wanted to do a fresh install this time in the hopes of fixing some niggling problems which have propagated through my setups. However, something has changed: 1)vb guest additions no longer allow me to copy and paste (i'll worry about that later) 2)more importantly phpmyadmin no longer works as installed - Initially going to localhost/phpmyadmin gave a message that the page could not be found. So I have followed some instructions (sorry I know its vague I cant find them now) which have created a phpmyadmin directory in /var/www but now I get an error saying: the mysqli extension is missing. If I run phpinfo mysql and mysqli are listed. All I have done so far is install apache2 (working) install php5 (which I think used to come with apache) Install mysql server (and client for good measure) and install phpmyadmin I found a post of a similar question which suggested I should install php5-mysql (done) and edit php.ini and uncomment the line extension-mysqli.so - this is not there, so I tried adding it with no joy. I have restarted apache and still no joy on phpmyadmin. Any help is much appreciated as this is driving me nuts. Why the change for the worse - I was just starting to like linux! I'm running a windows 7 machine and the guest os is ubuntu 12.04 - I ran apt-get update before doing anything so all packages should be the latest versions.

• When can I publish a software tool written at work?

  - by AlexMA

  I'm working on a software problem at work that is fairly generic, but I can't find a library I like to solve it, so I'm considering writing one myself (at least a bare-bones version). I'll be writing some if not all of the 1.0 version at work, since I need it for the project. If turns out well I might want to bring the work home and polish it up just for fun, and maybe release it as an open-source project. However, I'm concerned that if I wrote the 1.0 version at work I may not be allowed to do this from a legal sense. Obviously I could ask my boss (who probably won't care), but I'm curious how other programmers have dealt with this issue and where the law stands here. My one sentence question is, When is it okay (legally/ethically) to open-source a software tool originally written by you for work at work? What if you have expanded the original source significantly during off-hours? Follow-up: Suppose I write the whole thing at home on my time then simply use it at work, does that change things drastically? Follow-up 2: Note that I'm not trying to rip off my employer (I understand that they're paying me to build products that they own)--I'm just wondering if there's a fair way of doing this for all involved... It would be nice if some nonprofit down the road could use my code and save them some time. Also, there's another issue at stake. If I write the library for a very simple, generic thing (like HTML tables in Javascript), does that mean I can never again do so on my own time without putting myself at legal risk (even if it was a whole new fresh rewrite or a segment of a larger project). Am I surrendering my right to write code for this sort of project for the rest of my life (without this company's permission), since the code at work might still be somewhere in my brain influencing me? This seems related to software patents, as a side-note.

• 12.10 no audio via hdmi and video speeds up

  - by jackson

  I have a laptop with an ati radeon 4200, on 12.04 everything worked fine, since upgrading to 12.10 I cannot get sound over the hdmi. When I switch to hdmi audio the video speeds up to about 2x. I can use the speakers in my laptop and watch video via hdmi with no problems. Things I have tried: Various tutorials to install the AMD/ATI drivers, all of which resulted in low graphics mode. Checked that everything is properly set in alsamixer, the sound utility and - installed pavucontrol and checked everything in there. Verified the output from cat /proc/asound/cards looks normal When I initially upgraded there was a plethora of problems which I believe were due to the old proprietary driver still being used but not compatible, after a few hours trying to fix that I decided just to back up and do a fresh install which works great except for the above stated problem. Any help would be greatly appreciated!! Finally hopefully this hasn't already been answered, I have tried a few different searches on the boards and haven't come up with anything. $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC269VB Analog [ALC269VB Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 0/1 Subdevice #0: subdevice #0

• File browsing on Nautilus extremely slow after upgrade to 12.04

  - by Tobelli

  One month ago I updated (no fresh install) to 12.04. Since then nautilus got extremely slow. When I open a folder that contains many subfolders I sometimes have to wait 4 seconds until everything is displayed. This has never been like that before, in previous versions I could always browse between my files extremely fast. I looked in "additional drivers" and changed from Nvidia current-version-update to the recommended drivers. This drastically increased the performance and speed of file browsing, unfortunately just for a couple of days. Now I am stuck again with the very slow Nautilus. I also tried to install the latest nvidia driver like it was suggested here: http://www.techlw.com/2012/03/install-nvidia-drivers-on-ubuntu-1204.html Did not work at all. Also when using the dash to try to find files it does not respond properly: does not find files or loads for ages until the file is displayed. I am working on an Acer Notebook with Intel® Core™ i5 CPU M 430 @ 2.27GHz × 4 6GB RAM GeForce GT 320M/PCIe/SSE2 64 Bit Ubuntu 12.04

• radeon display driver clones monitors while using Xinerama

  I'm trying to get my two Radeon HD 4770 cards working with three monitors. Xinerama works so far in the way that I have two fully working monitors were I can move windows from one to the other.

• Totem crashes immediately after startup in 12.10

  - by Sakib Hasan

  I did a fresh install of Ubuntu 12.10 and did sudo apt-get update && sudo apt-get update. Then I installed ubuntu-restricted-extras, audacious and vlc from Software Center. After that I tried launch Totem Movie player but in terminal following error comes up: (totem:9295): Gdk-ERROR **: The program 'totem' received an X Window System error. This probably reflects a bug in the program. The error was 'BadDrawable (invalid Pixmap or Window parameter)'. (Details: serial 1808 error_code 9 request_code 152 minor_code 9) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I tried purge and again install. But the error remains. What should I do?

• Recover Lost data/partition

  - by Kaleido

  This is what happened: I was running 12.04.1 and wanted to install 12.10. upgrade, but a fresh install. When setting up my computer I anticipated for this by dividing my 640GB HD in following partitions: 1. 60 GB for Ubuntu, boot 2. 576 GB for data, mountpoint /home 3. swap, 4GB The idea was to manually select the correct partition in the installer but I got distracted for a moment and selected the wrong option. Result: The installer started repartitioning the entire HD. When I noticed this I interrupted the installer, but upon reboot it was clear that I was too late, no OS to boot to. I booted from a Gparted Live CD to see if I could recover the data on my previous /home-partition, but it's gone. Is there any way to recover the lost data? I searched around and read alot about Testdisk, but in all the tutorials I've seen, the set-up has been much easier than what I'm facing. I've not only lost my partition table, it's been replaced. Thanks in advance for any ideas that might help! If extra info is needed, please specify and I will do my best to provide.

• How do I develop database-utilizing application in an agile/test-driven-development way?

  - by user39019

  I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

• Trying to move away from PHP/Yii: RoR, Python/Django or ASP.NET MVC? Your opinions please [closed]

  - by Örs

  I have a CS degree and I've been working as a web developer (front & backend) for about 2 years now. I've been working with PHP mostly because it was easy to pick up and find a job, but I've grown to dislike the language and want to try something new, and possibly get a better paying job. That last point is especially important because in my area (Romania/Eastern Europe) PHP jobs are mostly for people fresh out of college/high school, hence the pay is rather low. I've been working with the Yii framework which, if I understand correctly, borrows a lot from Ruby on Rails (convention over configuration, MVC, Active Record, scaffolding). Other than PHP I only know curly-brace languages (C/C++/Java) and bash so Python/Ruby might be a bit challenging. On the other hand I've been using Linux (with vim and recently Sublime Text 2) for almost 4 years now so Windows and a lack of a terminal would have its downsides as well. I'm leaning towards Python/Ruby because of my *nix bias (plus both look like fun), but I've heard great things about ASP.NET MVC as well. Any suggestions? PS: I think there are more jobs in ASP.NET around here, but that's not necessarily a plus, because there are a lot of CS graduates as well. tl;dr: Romanian PHP/Yii developer trying to move to Python/Django or Ruby/Rails or C#/ASP.NET MVC. Suggestions?

• How do I partition my Hard drive to install Kubuntu?

  - by Xdflames

  I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

• Grub2 attempting to boot hd1 when it should boot hd0

  - by JoBu1324

  I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

• sharing life experience

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year. Now, I want to construct webpage to guide fresh students by giving advise of yours and mines.Maybe, you wonder Why I want to construct webpage , I just want help the other student. I am giving a link to that question < http://stackoverflow.com/questions/3389465/how-should-i-study-programming-languagess If you have other advice, feel free. EDIT: This web cite, I think , is constructed to share member's life experience and also I know these experiences is valuable . So I have no right to want your opinion, But I want your opinion / experience even if you think it is not so helpful to other

• Velvet screen after grub selection

  - by Spleen

  After a fresh install of Ubuntu 11.10 64-bit, the boot seems to stop after selecting the ubuntu option (same with the rescue one) in the grub menu. At first I thought this was related to grub-efi, as I've had similar problems after a Ubuntu 11.04 update which replaced grub-efi with grub-pc and got me stuck on a "elf magic" grub console (https://bugs.launchpad.net/ubuntu/+source/apt/+bug/800910). While the 11.04 problem was resolved with a simple chroot and apt-get install from the live cd, that solution doesn't work this time. The drive with the bootloader is a sata3 ssd with 64 gb gpt (sdb1 20 mb efi boot partition fat16, sdb2 60 gb root ext4 and sdb3 4 gb swap) on a msi e350ia-e45 mainboard with a pair of 2 TB ext4 mbr drives for photos/music/movies. I've tried a few grub-install/update-grub with boot-directory sdb1 from chroot, but I cant seem to go anywhere. Even this guide: http://en.gentoo-wiki.com/wiki/Grub2#EFI (ofc I replaced grub2 with grub in the grub-install and efibootmgr commands) doesnt seem to get me anywhere. Any help or ideas are appeciated ;) edit: I guess its the combination of gpt/uefi that also seems to haunt f16 edit: same with 12.04 beta btw
