• Half-maximized windows misplaced after switching display

  - by Arild

  I have a laptop which I often plug into a larger screen with another display resolution. Thus I'm frequently changing the screen for the system to use. Also I've recently discovered the advantages of half-maximizing windows when working alternatingly in two or more applications. When changing screens, however the windows basically retain their absolute sizes and positions. So in my case the windows typically have their bottoms outside display, don't fill up half the display, etc. I have to half-maximize the windows again every time I switch screens. I'm thinking this should be subject of a bug report but I find it difficult to know where to file them. Any ideas on what package is responsible?

• Setup shortcut keys not working

  - by Tim

  In my Ubuntu 12.04, in keyboard settings, I didn't find a shortcut key for restarting X, so in "Customer Shorcut", I set up Ctrl+Alt+Backspace for command sudo restart lightdm. But after that the shortcut doesn't work. Is it because it requires root privilege? Also I have a SysRq key on my keyboard, which I think to be the "Magic SysReq Key". My SysRq key is shared with PrtSc key (for screen shoot), and is in blue which means I have to press Fn key at the same time to invoke SysRq instead of PrtSC. But every time I press Fn+SysRq, it always shoots a photo of the screen, same as just hitting PrtSc i.e. without hitting Fn. I wonder how to use the Magic SysReq Key? Does it mean the shortcut has not been linked to any command that is supposed for Magic SysReq Key yet? PS: My laptop is Lenovo T400 and OS is Ubuntu 12.04. Thanks!

• have a missing file, and cant run ubuntu upon start up, and hasnt the flash drive i used didnt work either, any help?

  - by trent

  when I first downloaded Ubuntu to install it, it downloaded quick and caused no problems to my laptop. but then when it came time to install it as one of my operating systems, it wouldn't run because it said a file was missing or damaged. so then I uninstalled it and re-installed it but I still had that same problem. so I tried a flash-drive version but that didn't work either because it wouldn't boot from that, nor would it detect my flash drive, (in this case, an old 4 GB mp3 player). any help or tips and ideas would be great, I just need a decent operating system because windows is getting to be terrible at the moment, just note I wanna run Ubuntu along side windows 8.1

• Inside the IBM Selectric [Video]

  - by Jason Fitzpatrick

  The IBM Selectric was one of the best selling typewriters of the 1960s and 70s and featured a rather unique digital-binary to analog system that controlled a typeball instead of a row of type bars. Check out this video to look inside. Courtesy of Bill Hammack of Engineer Guy Video, we’re treated to a peek inside the popular typewriter model and an upclose look at how the unique typeball rotates and tilts to precisely deliver each letter.

• Expand size of Edubuntu partition on dual boot PC

  - by trptplyr

  I wasn't allowed to update to the next release of Edubuntu recently. It gave me an error stating that I did not have enough space to run the update. How can I expand the size of the Edubuntu partition to allow me to update? I am new to Linux so I hope that I am giving you enough and correct information on my system. I am using an older Dell Inspiron 9400 laptop. My root.disk file is 16.3Gb and the system.disk file is 256Mb. I would appreciate someone to point me to documentation or give me instructions on how to do this. Thank you.

• Securing Mobile Apps in a Bring Your Own Device World

  - by Naresh Persaud

  As more and more business users begin using their personal devices to access corporate information and resources, the number of network access requests has risen dramatically.  Access Management products and strategies that were based on an employee accessing network resources from a single desktop PC were never designed to monitor and manage an employee that is using a desktop and a laptop, a tablet, and a smartphone all from outside the corporate network, and possibly from an unsecured wireless public network. A new approach is needed to manage the types and frequency of mobile app access requests - an integrated Platform Approach to Identity and Access Management that is location and device aware, that can warn you of unusual or high risk access.  A platform that provides standard APIs so you can manage your mobile apps the same way that you manage your enterprise apps. View the slideshow below to see how the Oracle Identity Management platform can help you secure your mobile applications and data in a Bring Your Own Device World.

• How do I fool 12.10 to think it uses Unity2d in order to get the resolution my screen can use?

  - by Konstapel Kask

  On a laptop (model older) I have two screens (one built in, one external). I wish to use them both at the same time, but the settings app complains: Requested size (2944, 1080) exceeds 3D hardware limit (2048, 2048). You must either rearrange the displays so that they fit within a (2048, 2048) square or select the Ubuntu 2D session at login. The problem though, Unity 2D has been discontinued. I have forced Ubuntu to render Unity in 2D mode (with the help of echo export UNITY_LOW_GFX_MODE=1 >> .xprofile in accordance to this askubuntu post. But the error message still remains. How can one get the resolution that my computer supports? Or, how can I assure Ubuntu that it truly does use a 2D session?

• If Ubuntu freezes when running off a USB drive, will it freeze after full installation?

  - by fearoffours

  I'm planning to install Ubuntu on an aging Compaq Presario V5000. I've established that the Unity desktop is not suited to this laptop, and am now using the standard (Gnome?) desktop. I'm grappling with ndiswrapper and my wireless chipset. But I'm still running it off a USB drive before I take the plunge and install properly to my internal HD. Part of my reticence in completing the installation is I'm experience freezes after about 10-20 minutes usage. Is this likely to be in any way related to running it off the USB drive?

• Regarding Lost Administrative Password

  - by Rex Haggard

  I'm working on a Ubuntu 10.04 (Lucid Lynx) system using a Panasonic CF-50 Laptop. My Client has completely forgotten his Administrative Password. He doesn't even remember entering one; however it is there. I've tried the suggestions on the WebSite and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Do you have a solution? I look forward to hearing your response. Thanks for your time and consideration. -- Rex Haggard 1967 North St. Apt. #15 New Orleans, La 70802

• How USB drives goes after system hard drives

  - by raihanchy

  I am using Ubuntu 12.04 LTS. My hard drives usually comes as: sda, with 'sudo blkid' and if I plug-in any USB drive, they comes as: sdb, sdc etc; after sda. That's fine!!! But problem arises after I restart my laptop with connecting those USB drives. They alter and comes first and hard drive goes to the end, like: 'sudo blkid' shows, sda, sdb for USB drives and sdc for hard drives. It's making problem to mount with /etc/fstab. I couldn't find any solutions for this. I would like to have any USB drives after my system hard drives, as in Windows. Please, help me at this point. Thanking you. Raihan

• Low process priority problem

  - by Svepe

  I have just set Ubuntu 12.04 64bit with Cinnamon desktop and 3.5.0-030500 kernel on my new laptop with IvyBridge i7. I decided to test its performance by running a single threaded CPU-hungry program that I often use for camera calibration. Unfortunately, it ended up running much slower than I have ever expected. After some investigation it turned out that the program priority is automatically changed from normal to low which makes the program even slower. I have also noticed that all user programs such as Skype and Firefox are set to low priority. I tried manually resetting the priority to normal or even very high using the "renice" command, which works temporary until the kernel scheduler (I guess) resets the priority to low. Is this a normal behaviour and how can I overcome the problem with slowing down the execution? P.S. I also tried with the 3.2 kernel, but the problem is still present.

• Which ATI driver version did 10.04 use?

  - by Jack

  I have a trouble with ATI driver with Ubuntu 12.04 LTS. When I install ATI driver in Ubuntu 12.04 via "Additional Driver", then I can't shutdown Ubuntu, it showed blank (black) screen and my laptop still run. Sometimes, my screen like that: http://www.youtube.com/watch?v=U9_iygesbBM But when I install Ubuntu 10.04 and install ATI driver via "Additional Driver", it's very good and no trouble I've seen. It's sweet but 10.04 is old and is supported to 4/2013. So I want to know why Ubuntu 10.04 works good better than 12.04 with ATI driver (in my case)?

• Image Collector Rips Web Page Images to Your Dropbox Account

  - by Jason Fitzpatrick

  Chrome: Image Collector is a simple Chrome extension that rips the images on the page you’re visiting to your Dropbox (or Google Drive) accounts. Just click the icon, uncheck any images you don’t want it to download, and click save. You can, technically, modify the script to download the images directly to your hard drive, but modifying it was a bit of a hassle and the default save-to-Dropbox action is so smooth we saw little reason to do so.

• How do I use a 4GB USB flash drive to install Ubuntu 12.10?

  - by Logan

  I've downloaded "ubuntu-12.10-desktop-amd64" and used Pen Drive Linux to get it onto my USB. I then restarted my computer (a Windows 7 Home Premium edition) and entered the boot menu to have it boot from the Sandisk USB (it called it Sandisk Cruzer Cruzer). Linux came up and asked if I wanted to try or install. I picked install, connected to my Wi-Fi, and installed it. After my laptop restarted, Windows booted immediately. I have tried several times and cannot get a choice between the two. P.S. I have used the Windows Installer, Wubi, but at the last second it gave me some kind of error.

• Periodic clicking sound from PC speaker

  - by John J. Camilleri

  After an update some months ago, my laptop has begun making a low, repeated clicking sound every few seconds. It is not being generated through the regular sound system, as altering the volume and even muting the sound does not make any difference. My regular audio works fine, by the way, so I am guessing this is some sort of PC speaker, since I cannot hear the click when I listen through regular headphones. Strangely, when I open the sound settings dialog the click magically disappears. I don't need to change any settings; if I simply leave the dialog open in the background then the problem disappears. Any ideas what this could be? I am running regular Ubuntu 12.04, and this is the output from lspci -v | grep -A7 -i "audio": 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Acer Incorporated [ALI] Device 0349 Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at 54200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel

• computer doesn't boot from usb ubuntu installer when trying to install it alongside windows 7

  - by ali

  I'm very noob at linux and installing techniques. I want to install ubuntu 12.04 from bootable usb flash alongside windows 7 ( also tried live CD but now working ) but computer is not booting from usb flash or LIVE-CD and boots windows 7 ( acer aspire 4750g ). and of course I have set the bios priority in the right way. There is one important point to tell that I have installed Fedora 16 on my laptop successfully and now I have it on my system. when I was trying to install fedora i got some error and searched about it and got this point that I should delete a .efi file and then installation went right. In this case , what should I do to solve the problem? ( I also don't need my Fedora anymore )

• How to restore GRUB without re-installing the OS?

  - by Calixte

  A friend of mine has a Packard Bell laptop that came with Windows pre-installed. I installed Ubuntu on it and it works fine, but everytime she tried to boot Windows on it (fortunately rarely) it fails and the computer is unable to boot any OS anymore. Upon boot, the computer stops on a black screen with a GRUB Rescue prompt. Is there any way to restore GRUB without re-installing Ubuntu? (preferably an easy way as I cannot do it for her and she is not extremely computer literate) Also (but less important), is there a way to configure GRUB (or something else) so that Windows won't destroy it on every boot attempt?

• 12.04 on Pentium Dual Core with 1GB or ram running slow

  - by Alex

  hey i have a Lenovo Thinkpad Laptop with Ubuntu 12.04 installed. It runs slow. I tried "System profiler and Benchmark" to test the computer. but the application quits and closes after the first few benchmark test. before it even gets to the other tests. So i tried "Hardinfo" that installed on the Puppy Linux live cd. that did the same thing (the apps look just a like). the memory usage isnt the problem on this pc. its the cpu processes. just running the "system profiler" app that comes with ubuntu uses about 34% on each core, default with nothing running its 5-10% on each core. i cant really find what the deal is other than that ubuntu is a cpu hog. so im testing unity2D at the moment to see how it goes. if you have any other suggestions, feel free to answer this question. thanks

• Installing Ubuntu before or after upgrading from Vista to Win 7?

  - by andresmh

  I just got a new SSD hard drive for my thinkpad laptop. I just installed Vista with the factory CDs. On my old OS, my main OS was Ubuntu but I do want to keep Windows on a separate partition as a dual booth system. I definitely want to upgrade to Win 7 though and I will get it in a few days. My question is: should I install Ubuntu now and then upgrade to Win 7 in a few days? or is that going to mess up with the grub (or something else)? If that is the case, then I'd rather wait to install Ubuntu until after I upgrade to Vista. P.S. I know that probably any kind of mess done by the Win upgrade could be fixed, but I just want to avoid wasting time.

• Xubuntu, LXDE, USB Booting

  - by Kosciak

  Welcome, My problem appeared today - I was using Xubuntu for a long time, but find out that LXDE should be faster than Xfce, so I installed it. After installing I followed tutorial for removing Xfce, cause disk in my computer is very small and I wanted to release some free space. I used command from this tutorial: How to remove xubuntu-desktop? but instead of remove I entered purge command… and rebooted at the end. And I uninstalled whole my things. The problem is in installing system again - it's old Sony Vaio laptop (PCG-GR250) and I have broken CD-DVD drive. It's possible to boot from USB? I can access recovery mode, will this help me? Please answer fast, because it's my brother computer, and his going to kill me if I won't fix this fast :(
