• Screen has 1px vertical dead area on the right side

  - by pileofrocks

  Meaning that I can not click anything on that 1px vertical area (such as scrollbars). Illustration (purple = screen, black = the dead area): I am thinking Compiz has to be the main suspect, especially as on a guest account, this problem does not exist. I have a dual-monitor setup and this does not happen on the 2nd screen. However, turning off the 2nd display does not make any difference. I had this issue already before upgrading to 13.10 and while doing that, I also resetted all Compiz settings and re-loaded my profile configuration file. I have tried disabling all Compiz plugins under "Window Management" What next?

• Ubuntu Server 12.04 Screen Resolution "Out of Range"

  - by Alastair Mackie

  I'm fairly new to ubuntu and have just installed Ubuntu Server 12.04 on a spare machine to experiment and play with! The installation went without problem, however whenever the OS boots the monitor displays a an error message saying the resolution is "out of range" and i can't see to do anything - i can wait as long as i like, but nothing appears. Ubuntu is the only OS installed so bypasses GRUB on boot, although the GRUB screen is also out of range if forced on startup. I can access a shell from the recover mode and i can get at a terminal through a LiveCD of the Desktop version but have had little luck with either. I've been trying to figure this out for days and i'm at a total loss. Any thoughts?

• finding a WUXGA or matte laptop

  - by John Paul Cook

  UPDATED: HP still sells 17" WUXGA laptops - details in the new paragraph at the end. Lenovo, Dell, Sony and Sager do not sell a 1920x1200 (WUXGA) laptop. I understand that manufacturers provide what there is market demand for. I also understand that HDTV and the 1080p standard is heavily influencing both monitor and laptop screen resolutions. But I do not understand why there is so little demand for a WUXGA laptop. Nor do I understand the popularity of glossy displays. I really don't like to look...(read more)

• Windows 7 won't boot from any bootloader except for Windows Boot Manager after partition resize

  - by user2468327

  I have a triple boot system on a single SSD: OSX, Windows 7, and Ubuntu. I use Chimera (basically another version of Chameleon) as my bootloader. Usually I can boot all 3 OSs without any issue, but after using GParted to make my Ubuntu partition 2 Gigs larger, Windows 7 throws me an error when trying to boot to it from either Chimera or Grub. The error is consistently: `0xc000000e can't find \Boot\BCD" (slightly paraphrased). However, I can still get into Windows by selecting Windows Boot Manager from the boot options in my BIOS. I've already tried several known fixes for similar issues, including bootrec /rebuildbcd (and variations), and BootRec.exe/fixMBR + BootRec.exe/fixBoot. I've also tried Chkdsk. At best this has made it so Windows 7 boots on its own by default (making me have to reinstall Chimera and change back my boot settings in the BIOS). At worst this made it so Windows won't boot period. Now I'm back full circle where I started. A detail that might be useful is that bootrec /rebuildbcd says that the number of found Windows installations is 0. I'm fairly certain that I don't have a hybrid MBR. Mainly because I have a UEFI BIOS, and with that, it appears each OS can support a GPT. So it would kind of pointless to have and deal with. I may be wrong though, I couldn't find any way of finding out for sure online. However, I know for sure that the version of Windows I have installed is the UEFI version, as well as every partition tool I've used to look at my boot drive tells me it's GPT. How do I get it back so I can boot Windows 7 through another bootloader so I don't have to manually select it in the BIOS? Preferably without a reinstall.

• Is the "App" side of Windows 8 practical for programmers?

  - by jt0dd

  I like the tablet-friendliness of Windows 8 Apps, and some of the programming apps seem pretty neat, but there are many aspects that make me think I would have difficulty using this format for an efficient programming environment: Unlike the desktop + multiple windows setup, I can't simply drag my files around from source, to FTP or SFTP file managers, between folders, web applications, and into other apps, etc. I can't switch between apps as fast. This could have different implications with different monitor setups, but it seems like a shaky setup for an agile workflow. The split screen functionality is cool, but it doesn't seem to allow for as much maneuverability as the classic desktop setup. This could just require me getting used to the top-left corner shortcut, but it does bother me that I have to move my mouse all the way up there to see my different windows. These aspects could become relevant in the event that Windows were to move further towards their "app" structure and less towards the Windows 7 style. I'm wondering if anyone has been able to utilize the "App" side of Windows 8 for an efficient programming workflow.

• Ubuntu 12.4 cursor changes

  - by mantic0

  I have a weird problem with my Ubuntu 12.4 dual screen setup (Toshiba laptop + one monitor). After a while the cursor on one screen completely changes its shape (not every time). I don't really know how to describe it because it's always something else. Sometimes I get four or five vertical lines instead of a cursor, sometimes I can only see part of the cursor, etc, sometimes weird shade appears. This only happens on one screen simultaneously. If I go to the other screen, the cursor appears to be fine but when I change screens, the cursor changes. I tried to do a screenshot but when I do, the cursor looks just fine. I'm using Unity and Gnome 3 but the problem is on both desktop environments. Nothing is wrong with my screen though because I'm also using Windows and I don't have any problems there.

  - by soekarmana

  just updated from 11.04 to 12.04, fresh install installed apt-cacher-ng and notice something strange about it its always downloading index file (Packages.gz) even though the file exist on the apt-cacher-ng's cache, so this is what exactly happened : on ubuntu 10.10 & 11.04 apt-cacher-ng installed & configured on my laptop, then i reload & install some packages after that i configure my friend's laptop with apt-cacher-ng proxy (192.168.1.1:3142), reloading repository was blazingly fast, finished in a second without using my Internet connection (checked on system monitor, total Received just 15kB) on ubuntu 11.10 & 12.04 apt-cacher-ng installed & configured on my laptop, then i reload & install some packages after that i configure my friend's laptop with apt-cacher-ng proxy (192.168.1.1:3142), reloading repository was really slow!, apt-cacher-ng redownload the index file from internet

• Apple Cinema Display 23" and grub

  - by Joshua Pruitt

  As per the title, I'm running my display on an older 23" Apple Cinema Display (because I still love it, darn it). I'm pushing it with an ATI Radeon DVI dual-link PCIe card. It works just fine, except GRUB doesn't seem able to push out the 1920x1200 pixel resolution needed in order to show me a boot menu! So..., I keep a smaller second monitor connected as the primary display so that I can see the boot menu and boot the system (I don't use that display once booted). This is a goofy work-around, and I'd like to just use my single display exclusively to boot the machine. I found some grub codes for higher resolutions, but not for 1920x1200. Is it capable of this? Did I just miss it? Thanks in advance!!!

• What hinders Ubuntu from getting traction in the professional field? [closed]

  - by Prasad

  If this is not the place to ask this, please forgive this Ubuntu cub, I want to ask, what do people do with Ubuntu? As an Ask Ubuntu user I can see that most of the users (including myself) are asking questions about entertainment related problems. Is that all? No commercial use with it? Do people make fun of Ubuntu or just pretending to be Ubuntu users and use Windows secretly? Please don't hate me or make fun of me, I know lots of people trying to make Ubuntu even better, and I know it's better than Windows (if Adobe software just work on Ubuntu, I won't see Windows logo on my monitor anymore). What hinders Ubuntu from getting traction in the professional field?

• 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.

• window borders, menu bar missing over VNC

  - by zacaj

  I'm running Ubuntu 14.04 with Unity and Gnome3, however I don't have a screen hooked up anymore. I have installed x11vnc and run it with "-create" so that it will create a new X11 session, however when I VNC to it, the menu bar, window borders, etc are missing, windows are ordered based on creation time, and cannot be resized. Now, I don't really care if I end up with Ubuntu or Gnome's window manager, as long as this doesn't mess up my normal desktop stuff if I should happen to hook a monitor up again, and I'm not even attached to x11vnc if someone can point me to a good complete tutorial using something else, but I've been trying vino and tightvnc and rdp and x11vnc is the only one I've managed to get this far.

• UPS power requirements for server

  - by captainentropy

  Greetings! So, I just placed an order for a new server. The company recommended that I get a 3000W UPS. (!) As best as I could I calculated the following wattage consumption based on benchmarked data or datasheets provided by the manufacturers of each component: number watts **total watts** MoBo 1 240 240 CPUs (E5540) 2 80 160 RAID cards (3ware) 2 18 36 RAM (6x4GB) 6 3 18 DVD drive 1 7 7 floppy 1 2 2 RE4 drives 8 7 56 WD20 drives 8 6 48 Intel X25 SSD 2 0.15 0.3 total = 567 So that is for the PSU requirements only. The PSUs in the machine are a 720W for the master node and 800W each for two subsystems. That's a total of 2320W that can be delivered by these PSUs. But that is 4X the amount being consumed, at most, by the components. I didn't count case fans or the eSATA card (3W maybe?) or what the PSUs themselves require but assuming I double or triple my calculations I'm not even remotely close to the 3000W UPS I was suggested to get. They run at least $1100. I could get a 2000W for about $750 or a 1500W for $450 and still be well over my estimated power need. I don't think I need a whole lot of run time in the case of a power outage, maybe 20 minutes max, enough time to shutdown if the power doesn't come on within 5-10 minutes. Any thoughts? Am I off on my calculations? Did I overlook something major? If so what are your suggestions for a UPS? Thanks!

• unable to enter bios

  - by fraz

  I have an asus desktop ( amd phenom X6 processor) which was preinstalled with windows 7. I wanted to install ubuntu on it (dual boot) but am unable to do so because of the boot order. So I thought of changing boot order thru bios. But it turns out, if I press any key while the computer is starting, it just doesnt boots. I can see that the keyboard and mouse are booted up. (the lights are on) but the monitor is in standby mode.. I tried tab, f2,f10, delete key. But nothing is working.. Is there a software or other alternate on how can I change boot order ? Thanks

• Maximize, minimize and close buttons are either not present or not working in Lubuntu

  - by jimirings

  As the title indicates, the maximize, minimize, and close buttons are either not present or not working on my Lubuntu desktop. In fact, it only seems to be Google Chrome that displays the buttons at all, and only the close button works in Chrome, maximize and minimize don't do anything. When I use regular Ubuntu, they're all there just fine but not on Lubuntu. This all seemed to occur after I hooked my netbook up to an external monitor while using Lubuntu. Not sure if that had anything to do with it or not, but it seemed too big of a coincidence to not mention. Any ideas what the cause and a fix might be? Thanks in advance.

• Frequent GUI pauses in Ubuntu 13.04 / Unity / Intel HD4000

  - by Simon

  I'm experiencing very frequent (and regular) GUI pauses on my system. Every 30 seconds (pretty much exactly) the GUI will freeze for maybe .25 to .5 seconds. The mouse stops moving, keys stop echoing and a stopwatch timer briefly pauses. I'm using the Intel Graphics driver available from: https://download.01.org/gfx/ubuntu/13.04/main I've looked in a few places and tried a few things for a solution: I've checked cron and anacron for scheduled processes. I've disabled background processes (eg mysql, postgres, apache) not that these were doing anything anyway I've checked the following posts and tried the suggestions there: Unity GUI pauses/freezes for less than a few seconds How to go about troubleshooting frequent system pauses I've watched the system using top and System Monitor and there are no spikes (or even blips) of cpu usage when the pauses occur. There are no obvious error messages in dmesg or syslog There is loads of free RAM (8GB+) and no swap usage If it helps it's a ZooStorm i5 laptop with a HD4000 GPU, 16GB Ram and an SSD. Any help / suggestions would be very gratefully received.

• update-apt-xapian-index uses 100% CPU, even when Update Manager is set to not check for updates

  - by Dave M G

  I have a slightly older laptop running Ubuntu 11.10. It runs fine, but frequently, when I start it up, the CPU monitor in my Gnome Panel shows 100% usage for for what can be up to five minutes or so. It seems that the offending process is update-apt-xapian-index, which, if I understand correctly, is the update manager checking for updates. I have gone into the update manager settings, and selected to never check for updates. I'll do that manually when I feel like I have the time to leave the laptop running for that. However, despite my selection, this still happens. Roughly 50% of the time or more, when I start my laptop, it runs update-apt-xapian-index. How can I get the update manager to respect my settings, or at least to get this process to stop eating my CPU cycles?

• Input Signal Out of Range 1920x1080

  - by Zach

  I've recently installed Ubuntu 12.04 on my computer. Now, every time I boot and when I shut down, my monitor goes blank and says "Input Signal Out of Range - Change Setting to 1920x1080 60Hz." Once the computer gets to the login screen, it's okay again. This problem also happens when I try to open any 3d app. My graphics card is NVIDIA GEforce 6150 SE. I tried updating the drivers, but it broke everything and I had to reinstall Ubuntu. Any help?

• Windows Server 2012 Hyper-V very slow

  - by Matt Taylor

  I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

• Wireless USB Adapter driver configuration

  - by Jones

  First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

• Track url from Amazon S3 using Google Analytics

  - by morktron

  I couldn't find any decent pay per view video solutions for low budget clients. So I'm considering using a membership extension with Joomla and hosting the video with amazon S3. The only issue is that once someone has signed up to view or download the video if they have any web development experience they will be able to get the url of the video and freely publish it on the web. How can this be prevented? It looks like it can be done using IAM User Temporary Credentials - AWS SDK for PHP but the client would prefer not to have to pay someone to spend hours writing custom php code to get this to work. With Amazon s3 I could at least check the log files I guess to manually monitor the url but is there a way to track the url with Google Analytics? or is there a more elegant solution?

• How to disable DisplayInfo for Intel i810 when there is no xorg.conf

  - by user86954

  I'm testing Ubuntu 12.04 on an office desktop. This machine has an integrated Intel i810. This very machine used to run Ubuntu (or kubuntu) quite well, until the natty narwhal release, when the xserver started freezing. This seems to be caused by an issue with a call to the video bios, which can be circumvented by disabling the option DisplayInfo. I tried creating an xorg.conf by using Xorg -configure, but it produced an error after trying to make a file. I did have a file, and I put it in /etc/X11 with DisplayInfo false (maybe it wants "disabled"?), but it wouldn't boot at all until I removed that xorg.conf. There is no 10-monitor.conf file either. All I want to do is set the appropriate option so that my intel display doesn't freeze. Is there any other way I can disable the DisplayInfo? Andrew
