• Regulating brightness using Fn-keys

  - by richter12

  I have a laptop with the newest Ubuntu-version (12.04). I want to use the FN-Keys to adjust the brightness of my screen, but it doesnt work. Normally it should be FN+left arrow/right arrow. However adjusting the volume with FN+ up arrow/down arrow works fine. I already searched for a few soulutions, for example tried to replace in the Grub-File GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" or GRUB_CMDLINE_LINUX_DEFAULT="quiet splash cpi_osi=Linux" but it all doesnt work for my laptop. How can I fix this problem? Thank you very much! Richter

• suspend error on 14.04 LTS

  - by user1450663

  I've looked around and seems like various problems around suspend are wide spreaded for 14.04 release, nevertheless I haven't seen exactly my problem reported, nor my laptop model mentioned. So, the problem. When I press sleep button system seems to be going into suspend, i.e. screen goes black, it stops responding on the keyboard and wireless LEDs turn off, however the power LED doesn't go into suspend state and CPU fan also keeps spinning. But unlike the other problem described here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315435 when I close the lid and reopen it - system wakes up and goes back to normal locked screen state, so reboot is not needed. System details: This is a clean freshly installed Ubuntu 14.04, 32bit Laptop Dell D630 kernel 3.13.0-34-generic

• How can I use Ubuntu to rescue files from an NTFS drive?

  - by dago

  I reinstalled windows on the laptop of my daughter. Before doing this we made a copy of her music, pictures and so on. Unfortunately, the folder we created for the backup was empty (I checked after I reinstalled windows). Today a miracle happened, as suddenly the data were back but when Itried to copy them to another place thez disappeared again. Checking the drive with disk utility I got the message "filesystem is not clean". Is there a way to recover the data? Preferred solution would be a tool with a gui. The drive I need to repair is formatted in NTFS and is connected via usb to laptop.

• No Mouse Pointer - ubuntu 13.10

  - by Paul

  just installed 13.10 on my HP Envy M6 laptop and have no mouse pointer. My USB mouse does not work and neither does the track pad. When I booted from a USB key everything worked OK but once installed it seems to have broken the mouse. Unlike other posts, there is no flicker, it simply doesn't work at all. My laptop is an i5 with 6gb and dual Intel and AMD radeon graphics. Any help would be gratefully received as I really can't stand Windows 8 any longer. Thanks.

• Can I safely remove pre-installed software in Ubuntu 13.10?

  - by Andzt

  I uses a lots of Google Apps Product in my Laptop, Tablet and Mobile. Since I never use all pre-installed software in Ubuntu, can I remove it? E.g like: LibreOffice | I use Google Doc etc. RhythmBox | I use Google Play Music Thunderbird | I use Gmail, don't like client Videos | Watch online Messaging | Hangouts And other softwares like Remmina Client, BitTorrent Client. Can I simply remove it in Ubuntu Software Centre? I like my Laptop clean and having unmessy software that I never use. I normally use Chromium Browser to do all the stuff, I think I am heavy user of Google, and love the simplicity of Ubuntu. Lol! Can anyone tell or guide me? Thanks!

• Can I stop battery charging at say 80% and switch to AC?

  - by elim

  While I was looking for a battery management utility for my Dell E5420, I came to read this post - How can I limit battery charging to 80% capacity? . Sofar, I haven't found one that relates to my laptop. So, I wonder now if any battery manager utility can be found for my laptop specified above. I would be happy if someone could point me if such utility is available under Ubuntu 12.04 that can stop charging a battery at a certain percentage and to ONLY use A/C mode. Again, to start using battery mode when the A/C is off or when the battery level reaches at certain level. Thanks for all your help. Elim.

• Function keys on an external keyboard

  - by asymptotically

  So I bought a keyboard for my laptop. Unfortunately, it doesn't have the function key (though I know many people say it's useless). On my laptop, I control volume with the function key and F9-11. How can I get the same functionality on my external keyboard? The advanced keyboard settings don't have an option related to the function key. More specifically, it would be great if I could map it to my 'Menu' key which I'm never going to use. Or is there a way to get full functionality without it?

• Can't Reboot into Windows 8.1 from Ubuntu

  - by Extended Range

  I am newb in Ubuntu. Currently I am using an Acer V11 laptop with a pre-intalled Windows 8.1. I follow some guideline (http://www.everydaylinuxuser.com/2014/05/install-ubuntu-1404-alongside-windows.html) which successfully install Ubuntu 14.04 LTS alongside Windows 8.1 with UEFI enabled all the way throughout the installation and my current usage and a GRUB. But I got into some problem. The dual boot mostly works fine as I am able to successfully boot into either one of the Windows 8.1 or Ubuntu when stating my laptop. However it ran into issue after I start the device and use Ubuntu for a while (2 hour for instance) and then restart it: If I press the restart from Ubuntu, the grub still shows and I am still able to choose the Windows Boot Manager. But the Windows loading process was stuck at the Acer Loading Screen and I am not able to see the standard circular Win8 loading progress bar. Does someone know why would this happens?

• Getting wifi working on 14.04

  - by user286114

  I have installed Ubuntu 14.04 on my laptop. When I plug in the ethernet cable the internet works fine, but I can't see any wireless network in the networking manager. The wifi switch is definitely on on my laptop! It's a Dell XPS M1330. I'm not sure what the network card is - how can I find out? nm-tool gives me this: NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: 00:23:AE:28:FE:A2 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.1.26 Prefix: 24 (255.255.255.0) Gateway: 192.168.1.254 DNS: 192.168.1.254

• 12.04 boot failure after update

  - by msanderz

  I am using 12.04 and updated using Synaptic Package Manager. Now, however, when I turn on the machine it fails to boot, just a blank screen. If I shut off the machine and start it again and press F12 (on my laptop) to get the boot menu and select the default for HD-0 it boots OK. I had previously used Update Center and had a similar problem, which I corrected by reverting to "Previous" setup. Are there any fixes for this problem or am I unique in this situation. Ubuntu 12.04 Lenovo G575 laptop msanderz Thanks in advance.

• Core i7-620M vs Core i5-540M

  - by Shalan

  Hi, I'm recommending a laptop to a colleague, and the specific laptop he has chosen has the above CPU chips as options. Both chips have 2-cores/4-threads. The i7-620M is a 2.66 GHz (4MB Cache) while the i5-540M is a 2.53 GHz (3MB Cache)....both Arrandale architecture. He is a .NET programmer working with SQL Server and Oracle, and occasionally uses Adobe Fireworks for web-related design elements. He also loves playing around in Adobe Premiere Pro, and does a lot of media/video work. Would you notice any significant performance difference between the 2? The laptop manufacturer claims that the battery life on both is the same irrespective of the chip used (although I find that hard to believe), but there is a major cost difference between them, with the Core i7-620M being the more expensive. According to http://ark.intel.com, the one thing that seems different (besides the obvious speeds/frequencies/etc) is a feature called "Embedded" - what is this exactly? You can see the quick comparison here - http://ark.intel.com/Compare.aspx?ids=43544,43560 I would sincerely appreciate any advice me on this. THANKS!

• Can't get my OpenVpn client to connect

  Hi Guys, I am trying to setup a test vpn between my home desktop and my laptop. So far I have got the server on the desktop to connect fine but I can not get my laptop to finish the connection. I have tried several different configurations and they all give me the same result. Obviously it has nothing to do with my Client configuration but possibly something on my laptop? Here is the message I get in the log when it stops then times out and restarts.

• How can I forward an application with X11 in grayscale

  - by ??????? ???????????

  I am trying to run a graphical application at home and display it on a it on a laptop which is located about six routing hops away. The problem is that the connection is so slow (or rather there is so much GOOEY being transfered) that the mouse is unresponsive and it takes a "long time" to redraw the window even at a resolution of 800x600 pixels. The connection speeds are 10MBit up at home and about 1MBit down on the laptop, which I think should be sufficient for looking at some GUI in (almost) real time. Since this traffic is sent over over a secure shell, I have enabled Compression with highest CompressionLevel along with Ciphers set to blowfish-cbc. This has substantially improved the responsiveness of the application, making it nearly usable. However, my goal is to improve the performance even further by sacrificing colors and even frame rate. The application to be displayed a Qemu SDL window with a graphically-oriented OS in it. This is not strictly relevant, but perhaps there are options to tweak the SDL output which I am not aware of. A possible workaround would be to run the application in a "hidden" X server and enabling TigerVNC on that X server. This would automatically give me the benefits of an optimized VNC viewport, but the goal is to do without (reduce complexity). The question I'm asking is what are my options for reducing the data-rate generated on the server in order to make the graphical application more usable on the client. As mentioned, colors are not important and I could probably work with 5-16 fps. Both machines are running Gentoo with the software in question being: workstation X.Org X Server 1.10.4 OpenSSH_5.8p1-hpn13v10, OpenSSL 1.0.0e QEMU emulator version 0.15.1 (qemu-kvm-0.15.1) laptop X.Org X Server 1.12.2 OpenSSH_5.8p1-hpn13v10lpk, OpenSSL 1.0.0j

• Intel Wireless 4965AGN not achieving N throughput when connected to an Airport Express N network

  - by BenA

  I have an Intel Wireless WiFi Link 4965AGN adaptor in my laptop (HP Pavillion dv2000 series) which is connecting to a 5Ghz-only 802.11n network provided by an Apple Airport Express. The network is using WPA2 encryption. My desktop is also connected the Airport, via a Linksys WUSB600N USB adaptor. Both are running with the latest drivers, and the Airport is running the latest firmware. The Airport is also configured to use wide channels. The problem I have is that I never get throughput above 4MB/s when transferring files between the two machines. Even a pessimistic calculation shows a 270Mbps network as being capable of transfer rates at well above 10MB/s. I'm pretty sure I've isolated the issue to being the Intel adaptor, as wiring the desktop to the AP, and using the Linksys adaptor on the laptop immediately yielded speeds limited by the 100MB/s ethernet connection. I know that 802.11n is still a draft standard, and so mixing kit from different manufacturers can easily lead to poor results, but I was just wondering if anybody else out there has had success with this Intel adaptor on an N network? Or even better, connecting it to an Airport Express? Can anybody give me any advice on how to troubleshoot this issue? I should also mention that the Airport Express doesn't allow you to manually specify channels when running in N mode, and that I've been able to rule out interference from other Wireless LANs by scanning. There aren't any other 5GHz networks in my area. All ideas welcome! Update: A while later, I've just updated to the most recent drivers for both the Intel chip in the laptop, and the USB adaptor. Unfortunately this hasn't improved things :(. If anybody has any advice it would be be gratefully received.

• Ubuntu/Nvidia lists DVI dual cable as single

  - by Joseph Mastey

  I have an NVidia Quadro FX 880M graphics card, from which I am trying to drive 2 monitors: my internal laptop montior (15.6", 1920x1080, Nvidia driver says it's running via DisplayPort) and an external 27" monitor (Dell U2711, 2560x1440 native resolution, via DVI). I've hooked the dual DVI cable to the dual DVI port on my dock (Dell PR03X) and installed the proprietary NVidia driver, but I cannot seem to get the full 2560x1440 out of the larger 27" external monitor. Looking at the NVidia driver settings, the monitor's connection is reported as a single DVI cable, rather than a dual one, which would explain the reduced resolution. Does anyone have any experience with an issue like this? What can I do to make full use of my new monitor? (Possibly) Relevant Information: There is no DVI port on the laptop itself, but one is provided via the dock. The laptop and dock both provide a DisplayPort jack, but I have been unable to get this working on either w/ the monitor. I did have the nouveau driver installed when I installed the nvidia proprietary driver, but have since removed it (no change in the monitor situation when I removed it). The 27" reports a max resolution of 1680x1050. Thanks, Joe

• First Request to IIS Express Fails with 503 Service Unavailable, Second Succeeds

  - by Chris Moschini

  Each time I start my ASP.Net MVC 3 app from Visual Studio 2010, IIS Express launches and IE spins waiting. The request fails with HTTP 503 Service Unavailable. I hit Refresh in IE, and the request succeeds. All subsequent requests succeed until I stop debugging. The next time I go to start debugging, the first request fails again. Has anyone else experienced this? In IISExpress\applicationhost.config I have: <site name="ProjectName" id="6"> <application path="/" applicationPool="Clr4IntegratedAppPool"> <virtualDirectory path="/" physicalPath="c:\users\chris\dropbox\code\2010\SolutionName\ProjectName" /> </application> <bindings> <binding protocol="http" bindingInformation="*:80:laptop" /> </bindings> </site> I have this in my hosts file: 127.0.0.1 laptop And my Project is set to start with IIS Express, with Project Url set to: http://laptop It's very strange that only the first request fails, perhaps as though Visual Studio isn't waiting long enough for IIS Express to start? Is there some way to make it wait? Stopping debugging, making a change, and then starting again is one of the most common tasks I do so adding another step to get there is pretty annoying.

• Lenovo Wi-Fi Replacement

  - by user22910

  I recently got my T500 with a very poor signal Wi-Fi, Thinkpad BGN, a Realtek chipset. I would like to replace my Wi-Fi card with either the Intel WiFi Link 5100 or 5300. However, I read somewhere that Lenovo specfically "whitelist" their Wi-Fi cards to only work with their laptops. I could not find any of the Intel Wi-Fi, moreover any Wi-Fi cards on the Lenovo site. So, I went to hunt around in Amazon and found several sellers. Plus what sort of card do I require? There is a difference between mini cards and the full sized card, though I do not know which one my laptop supports. Here are the specifications for my laptop: http://privatepaste.com/8b0537bce0 I would like to have confirmation which one of these specific cards as posted below will work on my laptop (or the one you recommend to have): Intel Wifi Link 5300 Intel WiFi Link 5100 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft 2.0) Intel WiFi Link 5100 - Network adapter - PCI Express Half Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft) Intel WiFi Link 5300 - Network adapter - PCI Express Mini Card - 802.11b, 802.11a, 802.11g, 802.11n (draft)

• Why did MAC-Adress Cloning Fix My Router?

  - by FranticPedantic

  I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!
