How to get my laptop to detect SD cards inserted into its built-in card reader?

My laptop has a built-in SD Card reader but it cannot detect one when inserted.

Is it possible to set a VPN through Tor? and have functionality for Software Updates?

- by moazhmi

Gday, I have been trying to do a software update on Trusty both on terminal and software update app but that hasnt been successful, apparently my ISP has a broken transparent proxy. moazhmi@moazhmi-K52F:~$ wget -S http://extras.ubuntu.com/ubuntu/dists/trusty/InRelease --2014-06-04 17:34:52-- http://extras.ubuntu.com/ubuntu/dists/trusty/InRelease Resolving extras.ubuntu.com (extras.ubuntu.com)... 91.189.92.152 Connecting to extras.ubuntu.com (extras.ubuntu.com)|91.189.92.152|:80... connected.

How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

- by Adam

A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right.

Broke Ubuntu 12.04 either with Screencloud or Ubuntu Tweak

- by pgrytdal

Earlier today I installed the Screen Shot app "Screencloud" and after the installation Firefox was having problems. I didn't think much about it, just closed Firefox, then proceeded to change the toolbar opacity on Ubuntu Tweak. After restarting my system, hoping it would fix Firefox (because, you know, restarting fixes everything ;) ) I am able to go to the Log In Screen, type in my password, but then I get 3 errors regarding the Screencloud Ubuntu One, Imgur, and Dropbox plugins. After clicking the "Okay" on all three errors, all I see is my wallpaper. I am not able to access the terminal VIA CtrlAltT, but I am able to log out VIA CtrlAltDelete. I have tried all desktop environments I have installed (that, except for Unity 2D, has to do with Cairo Dock.) I hope I have provided enough information. If you need more, please ask. Please help! I would like to not have to re-install Ubuntu. Other info: OS: Ubuntu 12.04 I also have a Ubuntu 12.10 Live USB, but Ubuntu 12.10 hasn't run very well on any of my computers.

Low graphic mode after switching to fglrx drivers

- by MrKenkadze27

I have another problem on my laptop after trying to fix another issue. So, because of this issue, I wanted to switch to fglrx to fix it and after restart, I got this screen: I went back to terminal and I got rid of this problem by "purge"-ing the fglrx driver and removing it, going back to problem number one. I tried lot of methods to fix this such as this ones but they ether switched back to open-source drivers or didn't helped at all. So would anyone like to help? maybe give some commends to try? My Laptop has 2 GPU, AMD Radeon HD 7650M and Intel(R) HD Graphics 4000. AMD is running always making my laptop too hot. Here's one of the Xorg.5.log file paste, I am sure it will be useful finding my problem. Thanks! Please make answer easy to understand as I am not an expert, this problem is keeping me from being one. Also the AMD driver which can be downloaded from their site doesn't install, it says non compatible graphics card but Ubuntu Software Updater sure installs it.

Struggles to connect to network when using WPA with a BCM43225

When booting my laptop, it will try to connect to my wireless network, however a window keeps popping up asking me for my security password, which has already been saved. I have to keep deleting my network settings, and reconnecting, otherwise it keeps failing to connect. My wireless is set up with a WPA, I do not want to lower my security because of this, but it is a pain and can take me 15mins plus to finally connect.

Trouble installing Pokerstars on a Live USB without Persistence through WINE

- by Ricky Foster

I need to install any form of Texas Hold Em' on a Lubuntu Live USB that doesn't have persistence. I was able to download PokerStars.net by emulating the .exe (a windows type file) using WINE for Linux (Lubuntu). But, when I try to install, I have no room. The only place on the Live USB is in the root folder which is set to read-only. Is there any way I can change the read only properties of the Live USB while it's in use? So, to recap. I am running Lubuntu 13.04 and can't start in Persistent mode. When I start normally everything worked fine. I proceeded to Chromium and successfully downloaded Wine and the Pokerstars.exe. I right clicked the downloaded fiel then clicked Wine, the installer loaded fine. There are about 8 different disk icons and only the one containing system files is active. Is there any way I can use the terminal to install it to Root. Thanks in advance for your answer/alternate method (without having to buy another USB to install it to).

Problems with Intel Video Resolution on Acer Laptop Wide Display

- by ricstr

I have an ACER Aspire 5332 laptop which I have just installed Ubuntu 12.04 x64, which is causing some issues with the video display on boot and video resolution. First and foremost, it will only boot past the purple screen if GRUB has been edited to replace 'quick splash' with 'nomodeset'. Secondly, once it has booted with the the 'nomodeset' option, it does not allow me to change the resolution higher or lower from 1024 x 786. Is it OK to use the 'nomodeset' for normal use? Will this compromise performance of other devices? The video card is an on-board one, integrated within the Intel GL40 chip-set. The display is a wide-screen LCD, and under Windows could operate under various resolutions. Ideally I would like it to operate on a resolution to fit the wide-screen display as it a bit stretched out at the moment, and less desktop space as I am used to. I believe the optimal resolution is 1366 x 768. Below is some information from the terminal which may be useful. ricstr@Aspire-5332:~$ lspci | grep -i VGA 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 09) ricstr@Aspire-5332:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 0.0*

Apple's Java Mac OS X 2012-006 Update

- by Sharon Zakhour

The recent Java Mac OS X 2012-006 update from Apple removes the Apple Java 6 plug-in from your Mac. The Mac OS X Install FAQ will be updated with the next 7u release, but you may find the following information useful in the meantime. Q: I have installed Java for OS X 2012-006 and Apple Java 6 can no longer be used for applets or Web Start. How do I get it back? A: The Java for OS X 2012-006 update from Apple uninstalls the Apple-provided Java applet plug-in from all web browsers. You can download the latest version of Java from Oracle, which has improved security, reliability and compatibility. If you prefer to continue using Apple's Java 6 plug-in, you can follow the steps provided in How to re-enable the Apple-provided Java SE 6 applet plug-in and Web Start functionality. Q: After installing Java for OS X 2012-006, can I continue to use Apple's Java 6 alongside the OS X JDK or JRE for Java 7? A: If you want to continue to develop with Java 6 in a Terminal window you can modify the startup script for your favorite command environment. For bash, use this: export JAVA_HOME=`/usr/libexec/java_home -v 1.6` Some applications use /usr/bin/java to invoke Java. After installing Java for OS X 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java related command line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application. Also, this update removes Apple provided Java Preferences app. For more information on how to determine the default version of Java on your system, see Determining the Installed Version of the JRE in the JRE 7 Installation for Mac OS X page.

Keyboard-shortcut key-press-detection sensitivity settings

- by Juve

last week I switched from Ubuntu 10.10 to 12.04 and after setting up my keyboard shortcuts, e.g., CTRL+ALT+E for my favorite editor and CTRL+ALT+X for the terminal, I noticed that the behavior when pressing the appropriate keys changed somehow. I know this is very subjective and I am not 100% percent sure if I am suddenly just too lazy when using my keyboard, but here is what I noticed: To run your shortcuts, you usually press the modifiers first and in addition press the alphanum key. Now, if I hold the modifiers down very consciously and press the alphanum key afterwards everything works fine. However, I noticed that I may often release the modifiers a bit too early. In Ubuntu 10.10 (metacity/compiz) my keyboard shortcuts would still execute and my tools would pop up. This does not work anymore in 12.04. Nevertheless, I still believe the old behavior to be more intuitive and would like to have it back. I a nutshell: Is there a parameter to control the shortcut-key-press detection behavior? I already searched the ubuntu keyboard options and searched for "keyboard" in gconf-editor but could not find any hints so far.

Sound in Ubuntu 12.10 on Chromebook

- by Paul Mennega

I've got an HP Chromebook 14 that I've rooted and installed Ubuntu via Crouton (upgraded to 12.10) and most things are working nicely. One issue that I am having trouble solving relates to sound. I've got sound output that I can control via the individual app (e.g. Youtube), but when trying to control the volume via the built-in xfce4-mixer, I get the following error: GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem. Opening a terminal, I can run the alsamixer and control the volume levels. It is reporting back that the card is CRAS. I'd love to be able to do it from XFCE and the built-in mixer. I've tried re-installing the GStreamer packages, but no luck. It seems like I am close but not sure where to go from here. On a maybe unrelated note, plugging headphones into the headphone jack in Ubuntu also does not stop the sound from coming from the speakers and nothing comes through the headphones. Switching back to ChromeOs, everything works as expected, so I think that it's a driver issue.

The most mind-bending programming language? [closed]

- by Xepoch

From a reasonably common programming language, which do you find to be the most mind-bending? I have been listening to a lot of programming podcasts and taking some time to learn some new languages that are being considered upcoming, and important. I'm not necessarily talking about BrainFuck, but which language would you consider to be one that challenges the common programming paradigms? For me, I did some functional and logic (ex. Prolog) programming in the 90s, so can't say that I find anything special there. I am far from being an expert in it, but even today the most mind-bending programming language for me is Perl. Not because "Hello World" is hard to implement but rather there is so much lexical flexibility that some of the hardest solutions can be decomposed so poetically that I have to walk outside away from my terminal to clear my head. I'm not saying I'd likely sell a commercial software implementation, just that there is a distinct reason Perl is so (in)famous. Just look at the basic list of books on it. So, what is your mind-bending language that promotes your better programming and practices?

How do I get an application to appear as a choice in update-alternatives?

- by Jay

I separately installed the Firefox Beta and Alpha channels, and have desktop configuration files pointing to them in ~/.local/share/applications. However, stable Firefox is being used as my default browser by the system. (Firefox Beta used to be used until I messed with the "Default Applications" in System Settings, where it is not listed.) I tried running sudo update-alternatives --config x-www-browser to manually change it, but it's only recognizing Chromium and Firefox (stable) and showing them as a choice. What can I do to get custom desktop configuration files in ~/.local/share/applications to be seen as default alternatives? I think I may have to fiddle with the desktop config files, or with mimeinfo.cache or mimeapps.list? Running Oneiric. Here is the content of the firefox-beta.desktop file I created: [Desktop Entry] Name=Firefox Beta Exec=firefox-beta -P Beta -no-remote Icon=firefox Terminal=false X-MultipleArgs=false Type=Application StartupNotify=true StartupWMClass=Firefox Categories=GNOME;GTK;Network;WebBrowser; Comment[en_US]=Firefox Beta Channel MimeType=text/html;text/xml;application/xhtml+xml;application/xml;application/vnd.mozilla.xul+xml;application/rss+xml;application/rdf+xml;image/gif;image/jpeg;image/png;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp;x-scheme-handler/chrome;video/webm; Name[en_US]=Firefox Beta [NewWindow Shortcut Group] Name=Open a New Window Exec=firefox-beta -new-window about:blank TargetEnvironment=Unity

forward motion car physics - gradual slow

Im having trouble creating realistic car movements in xna 4. Right now i have a car going forward and hitting a terminal velocity which is fine but when i release the up key i need to the car to slow down gradually and then come to a stop. Im pretty sure this is easy code but i cant seem to get it to work the code - update if (Keyboard.GetState().IsKeyDown(Keys.Up)) { double elapsedTime = gameTime.ElapsedGameTime.Milliseconds; CalcTotalForce(); Acceleration = Vector2.Divide(CalcTotalForce(), MASS); Velocity = Vector2.Add(Velocity, Vector2.Multiply(Acceleration, (float)(elapsedTime))); Position = Vector2.Add(Position, Vector2.Multiply(Velocity, (float)(elapsedTime))); } added functions public Vector2 CalcTraction() { //Traction force = vector direction * engine force return Vector2.Multiply(forwardDirection, ENGINE_FORCE); } public Vector2 CalcDrag() { //Drag force = constdrag * velocity * speed return Vector2.Multiply(Vector2.Multiply(Velocity, DRAG_CONST), Velocity.Y); } public Vector2 CalcRoll() { //roll force = const roll * velocity return Vector2.Multiply(Velocity, ROLL_CONST); } public Vector2 CalcTotalForce() { //total force = traction + (-drag) + (-rolling) return Vector2.Add(CalcTraction(), Vector2.Add(-CalcDrag(), -CalcRoll())); } anyone have any ideas?

Change X settings to boot into laptop with non working screen using an external monitor

- by dassouki

My laptop committed suicide. Is there a way I can boot into my ubuntu using an external screen? Ubuntu 10.10 video: Nvidia 9500 gm i think I can get dual screen upto and until the ubuntu login screen at which point it goes back into laptop display only. Then I can just type and enter my password. The system (i assume boots into ubuntu) but I got no way of going onto the x or nvidia settings to change my display to external monitor EDIT well I booted into terminal using control shift F1 i think, and now I'm trying to reporgram x.org, but strangely it seems bland with not a lot of settings in it EDIT 2 xrandr returns "Can't open display" EDit 3 after some messing around with xrandr and xinit ... my x.org only displays one monitor instead of two in its settings although both, i.e. the laptop and external screens are both connected. EDIT 4 it seems that x.org now has a "screen" and "monitor" section, I can't seem to be able to boot linux into monitor. I get a "Monitor is not a valid keyword" in this subsection

Ubuntu 12.04 nomodeset fixes boot problem but causes screen resolution to get stuck

- by Thunder

I've been searching the askubuntu forum for the past 3 days trying to figure out what's going on with my system and I have tried a lot of things but to no avail. So, I will explain my situation and tell you what I have tried and I hope someone can help me :) I have an: HP Workstation xw4100 Pentium(R) 4 3.00 GHz 1.5 GB RAM NVIDIA Quadro4 380 XGL graphics card It came with Windows XP and I set it up (with WUBI) to dual boot with Ubuntu 12.04 After installation I had the problem that so many people had with it booting to a black screen (mine was actually booting to the terminal basic shell) that is fixed by adding nomodeset into the grub. When I do that, MY screen resolution becomes stuck in 1280x768 (as opposed to 1366x768 before adding nomodeset) (and also, when running XP the best resolution is 1280x720) When I go to "additional drivers" it doesn't show any proprietary drivers, so I manually downloaded them using this command: sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current but after rebooting, that made the graphics even worse (now stuck as 800x600) SO I tried to configure the drivers with sudo nvidia-xconfig but that simply created an empty xorg.config file. I found one place where a guy gave information to manually input into the xorg.config file but that had no effect at all. Lastly I tried to install previous versions of the NVIDIA drivers, but they wouldn't even fully install. So now I have just re-installed Ubuntu 12.04 and I either need to find a better solution to the first problem (nomodeset) or get the nouveau driver to correctly configure to work with my nvidia graphics. Thanks for your help ahead of time!

Input/output error, when trying to install on netbook [closed]

- by Ben

Been trying to install ubuntu on my Samsung NB30 netbook, but I have been running into the same error over and over again. [Errno 5] Input/output error This particular error is often due to a faulty CD/DVD disk or drive, or a faulty hard disk. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers), to check whether the hard disk is old and in need of replacement, or to move the system to a cooler environment. I'm installing from the USB bootable version, I get the exact same error at the exact same point when trying to install both ubuntu desktop and ubuntu desktop remix. I've tried redownloading both ISOs twice and I've tried two different USB sticks (one being completely new). I've tried installing from with in an ubuntu live session and I get the exact same problem. I've ran a bootable memtest and everything passes with no errors, I've also ran a dmesg in terminal after the installer fails here's what it reported - http://bit.ly/exAQRR Thanks in advance! EDIT: I know this was ages ago, but to anyone out there with the same issue, the problem turned out to be the downloaded image, my internet is poor at the best of times and the ISO failed the MD5sum check, if this happens to you I recommend you download the ISO image by torrent, it'll check the integrity of the file is maintained.

Impossible to boot Ubuntu on a USB stick (OS X Montain Lion)

- by user109513

I know this has been discussed over and over but I still cannot run Ubuntu on a USB stick. Here's the step I followed: 1. I downloaded Ubuntu 12.10 (ubuntu-12.10-desktop-i386.iso) from http://www.ubuntu.com/download/desktop which I renamed 'ubuntu.iso'. I bought my Mac mid-2010, it has an Intel processor. 2. I formated my 16GB USB stick with HFS+ File System following this tutorial: http://www.switchingtomac.com/tutorials/how-to-format-a-drive-or-partition-with-the-hfs-file-system 3. I opened a terminal and typed: hdiutil convert -format UDRW -o ~/Downloads/ubuntu.img ~/Downloads/ubuntu.iso It created ubuntu.iso.dmg 4. I ran 'diskutil list' and identified the device node assigned to the USB. 5. I unmounted it: diskutil unmountDisk /dev/disk2 6. Then, I entered the command: sudo dd if=~/Downloads/ubuntu.img.dmg of=/dev/rdisk2 bs=1m. It seemed to work. A Mac message poped up saying that the system doesn't recognized the disk, I pressed 'ignore'. 7. I ejected the USB using diskutil eject /dev/disk2, then removed the USB. 8. I rebooted the computer, plugged the USB key, pressed ALT.I could see my Macintosh partition and my Windows partition, but couldn't see my USB stick. Any help will be very appreciated :) Victor

Screen resolution stuck at 1024x768

- by Dananjaya

I just updated from Ubuntu 10.10 to 11.04 and have an issue regarding the screen resolution. I have Intel integrated gfx chip and my monitor supports resolutions larger than 1024x768. (in 10.10 I've been using 1280x1024) But as soon as I upgraded, I'm stuck with 1024x768 resolution and seems I can't change it. running xrandr In terminal yields the following results, Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x800 58.1 + 1024x768 60.0* 800x600 60.3 56.2 640x480 59.9 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1366x768 59.9 + 1360x768 60.0 1024x768 75.1 72.0 70.1 60.0* 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 1280x1024_60.00 (0xce) 109.0MHz h: width 1280 start 1368 end 1496 total 1712 skew 0 clock 63.7KHz v: height 1024 start 1027 end 1034 total 1063 clock 59.9Hz What maybe the problem? Is it a bug? What kind of steps I should take in order to get a higher resolution? (changing xorg.conf maybe?) Any insight is highly appreciated. Thanks in advance. UPDATE Screenshot after running xrandr --addmode VGA1 1360x768 As you can see, side bar is not completely visible and Ubuntu logo at the task bar is missing. Also when you open an application, the Task bar of the application (where it should go to the top panel) is missing as well..

Ubuntu stops using Nvidia driver after kernel upgrade

- by Daniel

Just updated and restarted, Ubuntu's doesn't display correctly. After restart, the desktop now looks like this. I've temporarily switched to the Nouveau driver. The update history reveals the kernel was updated, amongst many things; and the following were installed: linux-image-3.5.0-19-generic (3.5.0-19.30) linux-image-extra-3.5.0-19-generic (3.5.0-19.30) I've encountered this type of problem quite recently, so I decided to reapply the same steps, to solve the problem, as follows: sudo apt-get install linux-headers-3.5.0-19 sudo apt-get install linux-headers-3.5.0-19-generic sudo depmod -a sudo modprobe nvidia sudo /etc/init.d/*dm restart When installing linux-headers-3.5.0-19-generic, I get an error, message from terminal as follows: Setting up linux-headers-3.5.0-19-generic (3.5.0-19.30) ... Examining /etc/kernel/header_postinst.d. run-parts: executing /etc/kernel/header_postinst.d/dkms 3.5.0-19-generic /boot/vmlinuz-3.5.0-19-generic Error! Problems with depmod detected. Automatically uninstalling this module. DKMS: Install Failed (depmod problems). Module rolled back to built state. However, I ignored the above error and continued the steps with sudo depmod -a, installed nvidia-current, then did sudo modprobe nvidia, which yielded the following error: FATAL: Error inserting nvidia_current (/lib/modules/3.5.0-19-generic/updates/dkms/nvidia_current.ko): No such device Upon restart, the Nvidia driver now works! BTW, do those error messages imply I broke something? Just curious, cause I don't want to get happy I've fixed it, then it stops working later on. The system is Dell XPS-L702X, with NVIDIA GeForce GT 555M, and 17" screen.

Remove unwanted Mount option from Places Menu

- by Jack

On Ubuntu 10.10, I added a CIFS network share into /etc/fstab using /media/pub as my mount point. The share becomes visible on the Desktop and under Places (drive icon), which is what I want. But the problem is, Ubuntu 10.10 (unlike 10.04) creates another entry under Places with same name "pub", except this appears to be a mount shortcut rather than another link to the share. When I move my mouse over it says "Mount pub" and if I click on it, it will mount the share and again each time (if already mounted) - it does not display contents of share. In either case, an error pops up soon after "Unable to mount pub - Timeout waiting for mount to appear". The share itself is accessible, but I can't unmount via GUI, system reports its mounted multiple times and I have to unmount via terminal. (sudo umount -a) As I'm mounting the share at boot time, I don't need this manual option under Places. Is there an easy way to stop Ubuntu from listing it under Places? I have tried making the mount point under /mnt, this fixes the problem, except creates another as it removes the drive icon from Desktop and Places. I could create a bookmark, but just wondered if there's an easy fix to this unwanted entry under Places. Thanks
