• How do I install the driver for my Linksys AE1200 Wireless-N USB Adapter?

  - by Lewis Graham

  I recently downloaded Ubuntu from the main website with the hopes of dual booting it with Windows. While the operating system works, it says that I need to install a driver for my graphics card. When I type in my password the installation fails. I figure it is because I need Internet access. I tried to install my WiFi USB adapter with the installation disc but Ubuntu doesn't seem to run the setup when I click the exe. What are my available solutions as I would really like to use Ubuntu from my programming and Windows for my gaming needs? The name as read on the box is: Linksys AE1200 Wireless- N USB Adapter The description reads as such: ID 13b1:0039 Linksys (a comma messed up format) ID 046d:0a0b Logitech, Inc. ClearChat Pro USB (headset)

• MacBookPro 7,1 can only see one cpu

  - by gozzilli

  On a MacBookPro 7,1 running ubuntu 11.10, System monitor only sees 1 core (instead of 2). cat /proc/cpuinfo | grep 'cpu cores' also gives: cpu cores : 1 I followed this guide and added acpi_apic_instance=2 to the line with GRUB_CMDLINE_LINUX_DEFAULT, but that doesn't seem to change the situation. What can I do? I'm using rEFIt, installed under MacOS, and running in dual boot with MacOS. After the rEFIT menu, I'm still presented with the GRUB menu (I'm assuming that's normal). I saw similar posts on this matter, but could not fix my problem with what they suggested. EDIT: With the method mentioned above the computer runs sometimes with 1 core and other times with 2. Why is that? How can it be fixed?

• Installing drivers for an ATI 6950

  - by aj.esler

  Is there any way to get ubuntu to recognise an ATI 6950? I have tried installing the proprietary ATI drivers, but these do not seem to work properly. It seems to screw up the gnome desktop, and starts booting into terminal. I'm somewhat of a linux newbie, so not really sure whats going wrong. I don't want to game on ubuntu, I just want it to recognise my dual monitor setup rather than mirroring the monitors, so any driver that does this is fine by me. It seems like the open source ATI radeon drivers will not support the 6950/6970 for some time, at least until kernel 2.6.38 is released. The card is also flashed with the 6970 firmware, not sure if this is important. I am running a 64 bit version of ubuntu, I installed ubuntu server 10.10, then installed gnome-desktop.

• Why is my Workspace switcher view skewed

  - by Lee

  I have been using Workspace switcher in Ubuntu just fine but recently have encountered this problem. The windows in the switcher don't fill the screen. I must have pressed some combination of buttons somehow but can't find any information anywhere in regards to resizing them. As you can see in the screen shot it looks like a perspective view or something. http://i1115.photobucket.com/albums/k553/lmt337/Screenshotfrom2012-07-04103519.png I should also add I have a dual monitor setup and nvidia graphics. The switcher still works but the fact the screens dont fit my actual screens is driving me nuts. Thanks in advance for any help.

• GRUB install error

  - by Rohit

  Whenever I try to install Ubuntu, I get a fatal error that reads: 'Executing'grub-install /dev/sda' failed. This is a fatal error.' Its the same as this, but my graphics appear to be running fine. Also, I'm a complete novice at this and really need simple instructions to understand what I'm doing. I've tried booting from a LiveCD and a USB stick. I don't want to dual boot it because its an old computer that I erased XP and plan on only using Linux on it. When I used a USB stick and set the persistent file storage high, I was able to run it, but only as long as the flash drive was plugged in.

• display port on x230 not working

  - by Aaron

  having problems with my new lenovo x230 - using dual montiors, only vga registers anything. This has the Intel graphics controller : 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) TO get it to even boot, had to add the nomodeset parameter to the kernel. Otherwise will not even start up X Ive upgraded my kernel to the latest 3.6 with no difference. The display section reads the monitor as the only display and labels it as laptop. Cant seem to get it to work! Any help would be greatly appreciated.

• The use of LGPL for Commercial use

  - by Smarty Twiti

  I am trying to make my first app for sale, I would like to ask some questions for those who have already sold their software: Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers? for example, if your customers/ competitors from the market reveal technology/secrets that you used in your solution (as LGPL requires that you make a Dynamic Link (.DLL) for your libs and you clearly tell the use of a Lib/Framework ...). Full story: For my project, I used a framework LGPL/commercial (Dual License) the second one it was too expensive (about 3000 USD) which pushed me to use LGPL.. however I still concerned.. That is why I ask for advise and especially motivations... Please do not hesitate to participate... Thanks in advance.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• Why does update-grub not find ubuntu 11.10?

  - by Klaynos

  I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks

• keyboard shortcut to switch focus between separate X screens?

  - by ang mo

  I'm using XFCE on a dual monitor setup, with Xorg configured to separate X screens (neither twinview nor cinerama is working on GF470 with latest nvidia drivers). I'm not using xrandr. Suppose I have firefox running on one screen (:0.0) and thunderbird on the other (:0.1). When I want to switch focus from thunderbird to firefox, I need to move my mouse pointer to the firefox window and click (alt-tab switches between windows on a single screen only). Is there any keyboard shortcut for switching focus between screens?

• How can I get a 1920x1080 resolution?

  - by Sam T.

  I a newbie Linux and have just installed Ubuntu in a dual boot with Windows 7. I love the interface of Ubuntu but unfortunately I can only get a 800x600 or 1024x728 resolution with black bars all around the screen. I have an nVidia GTX 570 graphics card and an Asus 1080p 23" monitor. What may be of note is that I had to use the nomodeset command on installation of the boot would get stuck at a line with "nouveau", which I understand is to do with the drivers. Additionally, when I type in xrandr to the terminal, it comes up with the error message "failed to get size of gamma for output default". I guess what I am looking for here is someone who could explain to me really simply the steps I have to take to get a full 1080p resolution, at which point I am sure i will become a great fan of the OS! Thanks in advance, Sam T.

• Mouse Problem on Ubuntu 12.10

  - by KashmirHackers

  I had a strange mouse problem on Ubuntu 12.10(64-Bit), the problem is that when I turnoff power supply/power goes off, the red laser light of my mouse also goes off and my mouse stops working but it works fine when A/C power supply is on. First I thought my mouse or my laptop's USB ports had problem but since I am using Dual Boot with windows 7, I checked my mouse on windows 7 and it works fine, even I turn off power supply. Today,I thought that I should give a try to Linux Mint 14-RC (which is based on same Ubuntu 12.10) and after installing linux mint when I plugged in my mouse it worked fine even though power is off. Don't know what is really going on, and I am afraid if I reinstall my Ubuntu 12.10 the problem will remain.

• Ubuntu 13.10 - Black screen after logging in after installing nVidia drivers

  - by Javacow

  I recently installed Ubuntu 13.10 in a dual-boot with Windows 7, so I'm still quite new to using Linux. Most things were working fine, and I could log in normally (apart from the first login after install, which spent about 2 minutes on a black screen before going to the desktop). I installed the restricted Nvidia drivers with the command: sudo apt-get install nvidia-current Since then, after I enter my password and log in (the login screen itself works perfectly), I get a black screen with the cursor and nothing happens from that point onwards. Basically, what I would like to know is how to get back to the normal Ubuntu desktop and (hopefully) still be able to use Nvidia drivers.

• No wifi using Ubuntu on laptops

  - by Pete G

  I have loaded Ubuntu onto two different laptops and both had the same result...no WiFi. I could access the internet if I plugged into Ethernet port but try as I might, I just could not access WiFi. I even tried Wine to install a Windows based external usb WiFi device but again...nothing. It functioned normally in Windows but with Ubuntu installed....nothing and this was the same whether it installed just Ubuntu or dual booted with Windows. Any suggestions? Thx!

  Windows Phone 8 : Nokia dégaine ses Lumia 920 et 820 Pour contrer l'iPhone 5 ou le Galaxy SIII, suffisant ? C'est peu dire que l'attente était grande, une semaine après la présentation du Samsung Ativ S et une semaine avant celle de l'iPhone 5. Les premiers Lumias de Nokia sous Windows Phone 8 devaient être annoncés. Les rumeurs parlaient de terminaux avec des batteries rechargeables sans fil. D'autres, d'écrans de 4.3 et de 4.5 pouces, de processeurs Dual Cores cadencés à 1.5GHz, et 1GB de RAM. On parlait également d'un APN/Caméra à 8 megapixels (décliné de la technologie PureView de Nokia à 41 Megapixels)...

• Need to adjust touchpad edge scroll area

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the touchpad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature. Thanks a lot.

  I have been running Ubuntu 10.04 with GeForce 8800 Ultra graphics card without any problems for many months until a few days ago, after some updates, everything stopped working.

I have a dual boot and WinXP is not having this problem with the 8800 card. So, elementary... What's going on between Ubuntu and Nvidia? Best regards Gunnar
