• configuring separate X screens instead of TwinView

  - by fimre

  My Sony Vaio laptop is connected to an external Samsung monitor and my nVidia driver is configured in TwinView mode. Everything is OK with this, however, I can not adjust my displays individually so at the moment my external display is a little bit darker which disturbs me a lot. I tried the Separate X Screen mode but after restart, my laptop display was white with a black x sign mouse pointer and the external display normal desktop. Is it a bug or something I missed? The idea is that using Separate X Screen mode, I could adjust my displays individually. I would really appreciate someone would guide me out of this situation. Thanx in adv..

• Can I get some advice on graphics cards please?

  - by Victor9098

  I know that Steam for linux is on the way and have been seen a lot of games appearing in the Ubuntu Software Centre of late but my system lacks a decent graphics card and was hoping I could get some recommendations. The desktop is a Packard Bell Imedia S1800 (or Imedia D3526 UK) with the following specs; Memory: 3.8 GiB Processor: Pentium(R) Dual-Core CPU E5800 @ 3.20GHz × 2 The system lists the graphics as 'unknown', though I think its just an integrated Intel card From what I can see there is a free PCI-E x16 slot. Any advice would be great, thanks!

• How do I install ubuntu 12.04 over windows HP

  - by Cakemix

  I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

• PC won't boot up after installing 11.10

  - by bakhshu

  I have a HP/Compaq s1010z (AMD64) desktop and installed 11.10 from a CD (using the entire disk). So it formatted the entire drive, went through installation and then it ejected the CD and asked me to click the Restart button, which I did. It rebooted fine the first time, but any time thereafter, it fails. Meaning, after the initial BIOS screen, the monitor seems to be stuck in limbo with a text cursor blinking on the top left corner, as if it can't find anything to boot from. At first I tried reinstalling (reformat entire drive again) - no improvement. Then I did an in-place re-installation (leave home dirs in place, just redo the OS), nothing there either. Then I put in the 11.04 CD, changed the boot order to CD first, and got the CD menu, chose 'Boot from first hard disk' and it booted fine. The problem is that I can't boot without the 11.04 CD, how ironic! Any ideas?

• USB key will only be mounted by gparted [?]

  - by user2413

  Hi, When I insert by usb key nothing happens (i.e. the drive is not visible). I can mount the USB drive from gparted though (and then it's suddenly recognized). It's not particular to any USB key. This only happens on my laptop (on the desktop the same key will be mounted upon plugging it in without any problems). Finally, the key is formated as fat32 and dosfstools and mtools are installed (through gparted claims otherwise). what's the catch? EDIT Also, gparted offers me the option to mount the key on "/" : shouldn't that be "/media" (or has this changed ?)

• Defaulting internet requests to wlan0 when also connected to eth0

  - by Dudemcman

  I am trying to configure an Ubuntu 10.04 desktop edition as a server. I currently have the DHCP server working through eth0. My problem is that I only have one Ethernet port, and am receiving Internet though a mobile hotspot on my phone through wlan0, and whenever I attempt to connect through wlan0 and eth0 I am unable to access the Internet through the server or the clients. When I disconnect from eth0 I then regain access. I have searched extensively for a solution, and have come up short. Any help is appreciated.

• No splash screen on hibernate

  - by Marky

  Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

• No background/wallpaper in Ubuntu 12.04 - what to do?

  - by magnesus

  This is how my desktop looks like after moving Firefox window arround: The background just doesn't redraw, there is no wallpaper. It is like that since update to 12.04 - it was the same in 11.10 but I had special intel drivers then that fixed this problem. Doesn't seem to be fixed in 12.04 even with the ppa I was using then. What can I do? I couldn't find anything about it on Google because results were unrelated. :( I have Samsung RF-511 notebook with Nvidia card turned off - so it's using only Intel from i7.

• Flikering line on top of display

  - by jaskaran

  I just bought a new Dell Inspiron pre-installed with Ubuntu 11.10. All was fine until I updated the OS. Since then, I have this flickering line at the top of my screen and it won't go after rebooting or changing the screen resolution. It gets really annoying. I don't know which update did this. I tried reinstalling the image from Dell, and it worked fine until I applied the updates. I tried to take a screen shot but it does not show. The line seems to be outside the desktop area. Help please... Thanks!

• How do I access an external hard drive plugged into my router?

  - by Shawn

  I am running Ubuntu 11.10 and I own a Netgear N600 Wireless Dual Band Router with a USB port built into it. Naturally, the router came with instructions on how to mount and view this drive with both Windows and Mac, but nothing about Linux. I have an WD Elements 1 TB external HDD that I would like to plug into the router and share across my home network. However, when I plug it in, absolutely nothing happens on my desktop. I checked on two different machines and nothing seems to indicate that the drive has been mounted (or is even seen at all) on either machine. I am fully aware that it may not be possible to do this with a Linux system, but I was hoping someone might have a suggestion. Thanks!

• Why does my screen blank out for the duration of the Grub boot menu?

  - by hushs

  Upon booting, when I should see the GRUB menu, my monitor simply says: "No optimum mode. Recommended mode: 1600*1200". If I wait for a short while, Ubuntu starts to boot and it reaches the desktop. So I guess there is no video signal during that time, there's the grub menu but I cant see it and after the wait time everything is fine. I have the same problem when I log out for a short moment, before the log in screen is reached. and this also happens when i shut down ubuntu. The VGA is an onboard NVIDIA GeForce 7025.

• How do I replace Unity?

  - by Krista O'Connors

  I wanted to use Ubuntu 12.04 for its long term support. But I cannot stand Unity. I cannot find a way to replace it with compizconfig, so I tried replacing it with Lubuntu. When I restarted my computer started to load lubuntu, then just went right on with ubuntu as if nothing had happened. Likewise, it shows lubuntu when it shuts down. What is the deal? I'm confused here, is ubuntu 12.04 supposed to be an operating system or a desktop interface? Can I even run ubuntu with a Lubuntu interface? Is there a way to do this in compizconfig that I should be doing instead?

• Ubuntu user expectations from 12.04 and future releases

  - by Rick Green - Turbo

  How much further ahead is 12.10 vs 12.04 in respect to kernel updates and applications? Example: Gimp's newest release is 2.8 which runs equally as well in both 12.04 and 12.10 and probably will in 13.04. What restricts 12.04 from having "the same" look, feel, applications and kernel as 12.10 or the upcoming 13.04? I know that it's more than a name change.....it's whats under the hood that counts. Incrementally upgrading, I feel is safer than radical changes from release to release. Trying to keep a stable desktop and current user experience, how far can I take updating applications before I absolutely have to make a distro upgrade from 12.04LTS

• How to debug slow session start of Gnome 3?

  - by user65521

  After Upgrade from 11.10 to 12.04, the login process of Gnome 3 is extremely slow (It takes in the order of 60 seconds when it was in the order of a few seconds before the upgrade (Harddisk is a SSD!)). Running "top" in a VT shows that gnome-shell is producing about 90% CPU load while dbus-daemon is taking roughly 10%. The moment when CPU-load of gnome-shell drops to normal levels (around 2-3%) corresponds to the time the login process is terminated and the desktop is displayed. De-activating the four gnome-shell extensions (Alternative Status Menu, Quit Button, Remove Accessibility, system-monitor) that I have installed does not have any effect on session start up time. Login to Gnome classic does not show the slow session start. The system logs do not show anything suspicious. Thus, what is the best way to identify the underlying problem?

• Is there a ppa or repository where we can update LibreOffice to version 3.6?

  - by josircg

  On http://www.libreoffice.org/download/ there is only RPM version - when great majority of Desktop Linux users are using systems based on APT... ppa:libreoffice/ppa seems to be very outdated with version 3.5 It's frustating to see several fixes on Windows version and Ubuntu versions so outdated... People generally reply as: we don't update due to security/stability reasons, etc example 1 example 2 why don't you compile yourself ? For those easy answers, I generally reply: let me decide which version to use at my own risk. I just want to try a newer version and I trust on LibreOffice devs. I understand that update a core lib is very dangerous but Libreoffice is an user application and it don't just break the whole system. Why don't I compile ? Because I am a regular user and don't have time to learn it. I would love to have this time but unfortunately, I don't have. Red Hat/Fedora guys have the same concerns but they update their LibreOffices...

• Windows 8 Location Services

  - by ryanabr

  I spent the afternoon with the Geolocator object in the WinRT and Widows 8 platform. I have also been working with doing Windows Phone 7 development, and first had to wrap my head around the fact that while similar, it is not the same as the GeoCoordinateWatcher that environment. I found a nice example here http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66 But the behavior of my app wasn’t the same. Once you ensure that location services is enabled by following these instructions: http://msdn.microsoft.com/en-us/library/windows/desktop/hh768219.aspx Location Services was still disabled. From everything I read, it sounded like the first time you try to use the Geolocator object, the user would be prompted to allow to “Access to your location”. After nosing around I found the issue. You need to add the location service as a Capability in the Package.appxmanifest file: After checking the box, I was prompted to allow access to location services as expected the first time I needed to use it.

• Switching to an external display, when primary is broken

  - by Shazzner

  I've successfully install Ubuntu 11.10 Desktop (x86) on an old(er) laptop that unfortunately has a broken screen, so there is an external monitor plugged in. On the livecd it come up on the secondary display just fine and I was able to install ubuntu and everything. Unfortunately when I reboot into Ubuntu proper now, the secondary display is off and I'm literally driving blind here trying to switch it to the secondary display. Using Nvidia open source drivers. Things I've tried: Rebooting back into livecd, mounting the partition and trying in vain to find a config file (it uses the open source drivers so no Xorg.conf I could edit manually) Trying to blind-type xrandr settings into what I hope is terminal: xrandr --output VGA1 --auto (nothing happened) Trying to blind install openssh-server so I could ssh into it and maybe configure it from my working computer. For some reason though, no luck. Ubuntu really should default to expanding to all screens for this use case.

• Can't open Minecraft with java

  - by Shingaling

  I know this has been asked here before, but none of the solutions have worked for me. I have a fresh install of Ubuntu 12.04 on my system and I installed Open Java 7 and I downloaded Minecraft. I right clicked Minecraft went to properties and set it as an executable and then went to open with and Java is no where to be found in the list. I made a new Java desktop file in /usr/share/applications and now when I go to the list Java is there and I set Minecraft to open with it by default but when I open it nothing at all happens. Now how am I supposed to get Minecraft to work?

• Accidentally deleted my windows 7 while installing ubuntu, trying to reinstall it

  - by user286874

  I had Windows 7 Ultimate on my desktop and I believe have downloaded the correct ISO file. I've been trying to use GParted and UNetbootin to create a bootable usb by formatting to FAT32, flagging the boot box, and writing to the flash drive with UNetbootin, but there have been problems. When I select my flash drive in the BIOS, it just reflashes the BIOS stock MSI picture 4 times then boots to Ubuntu anyway. Details: it's a new computer, self-built, hasn't shown any problems in the past, got Windows 7 through r/softwareswap so it's a MSDN file, the flash drive is a Sandisk U3 Cruzer, I uninstalled the bloatware when Iwas using Windows 7, but in the BIOS it still comes up as "Sandisk U3 Cruzer" I don't have a cCD/DVD drive. I dont care if I have to completely delete ubuntu in the process, I just need Windows 7 back by monday. I think the problem is because of the cruzer and am going to pick up a different flash drive today.

• How can I fix unreliable Unity startup?

  - by Vagrant232

  When I log in, either Unity loads perfectly or it just doesn't; all I see is my desktop background. Commands don't seem to work and I can't switch to the terminal view. No matter how long I wait, Unity doesn't start. I never had this issue with Oneiric Ocelot. Other GUIs such as GNOME 3.4 don’t seem to be having that issue. I've got MyUbuntu, Ubuntu Tweaks, CompizConf and other tweaking tools installed. Could they be causing the problem? If not, what should I do? I'd really like to use Unity again. Thanks in advance!

• How can I disable update checking on boot?

  - by Chauncellor

  I'm running off of a thumb drive with very average read/write speeds and automatic update checks makes the bootup far less pleasant. Since I manually update via apt there's truly no need to notify me like on a normal desktop. In older versions of Ubuntu there was an item to disable this behavior. On 12.04 this is no longer the case. would it be the 'unattended-upgrades' item in /etc/init.d? If yes, would simply removing the init script would solve my problem?

• Internet Not Working... Initially Worked fine

  - by Sneha429

  I am using an HP Pavilion desktop, not sure of exact model, etc. Initially saucy looked and worked great. It's my parents, and after two days of no issues, they started having more than a few. The mostly use the internet to access email and videos. I believe Google Chrome was the only application they used. Then, the internet stopped working. Restarting didn't fix it, neither did turning the internet on and off. The computer went from lightening fast to inexplicably slow. I've read some other posts about the internet not working, but none seemed applicable. Any suggestions?

• How do I allow Ubuntu to use more space on my computer?

  - by anonymous

  Ubuntu currently won't use more than 4GiBs on my computer, but I need more space. My computer can hold much more than 4GiBs. How do I allow Ubuntu to use more? Please give step-by-step instructions in plain English. Update: I'm referring to my Ubuntu operating system. I installed it using Wubi through Microsoft Windows. I deleted Wubi from my Windows desktop after installation. All I want is to expand my Ubuntu operating system. I plan to gradually transition from Windows to Ubuntu and so I'll need to transfer more files and programs from Windows to Ubuntu in the future. Right now, I already need more GiBs for Ubuntu. I can barely use Ubuntu right now because there's almost no space left. I simply want Ubuntu to use what space I need it to use. People, please quit complicating this issue and inform me how to make Ubuntu use more space.

• Custom widgets/controls in application indicators

  - by markitusss

  I want to develop an app for ubuntu, that integrates inside the calendar indicator/menu. It should allow to enter info right from it, and have several controls like input boxes, drop downs, spinners and buttons. Is this possible to integrate/replace the standard date/time indicator? If not, is it possible to create it as a separate indicator that when clicked opens a popup with all the controls and stuff? I want it to look as part of the sys tray and not as a separate desktop app. I'm using Quickly for this. Thanks for your help!

• Low display resolution under Ubuntu 12.04

  - by Chinouk

  I had some problem after installing new drivers for Nvidia. After having followed the instructions answered to this question, I now only have the Nouveau open-source driver. I can have access to my desktop, but I'm stuck with a 640x480 (4:3) resolution. No other resolution is proposed in the dropdown list of the "Displays" utility. I tried installing the two Nvidia drivers suggested in the "Additional Drivers" utility, but each one broke my display again. Now that I have reverted back to Nouveau again, what should I do to get a higher resolution ?
