• Bluetooth not working on Acer 3820tg (Ubuntu 12.04)

  - by Iohannes

  After upgrading to 12.04 (it was done by a complete reinstallation), bluetooth doesn't work anymore. Before (I think it was Ubuntu 11.04), I just followed instructions on this page and copied /lib/firmware/ath3k-2.fw to /lib/firmware/ath3k-1.fw and everything was fine. But in 12.04, there isn't any ath3k-2.fw in the /lib directory, so this method is not possible. Also, pressing Fn+F3 doesn't work. I would appreciate any help. Some further information (I hope it's enough): dmesg [ 23.063710] Bluetooth: Core ver 2.16 [ 23.063740] NET: Registered protocol family 31 [ 23.063743] Bluetooth: HCI device and connection manager initialized [ 23.063746] Bluetooth: HCI socket layer initialized [ 23.063747] Bluetooth: L2CAP socket layer initialized [ 23.063972] Bluetooth: SCO socket layer initialized [ 23.066930] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 23.066934] Bluetooth: BNEP filters: protocol multicast [ 23.068422] Bluetooth: RFCOMM TTY layer initialized [ 23.068428] Bluetooth: RFCOMM socket layer initialized [ 23.068430] Bluetooth: RFCOMM ver 1.11 lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0020 Intel Corp.

• Ubuntu 12.04.1 LTS and Nvidia dirver (304.51) 64bit: problem 640x480

  - by nibianaswen

  I have a problem with this configuration: Asus K55V, Ubuntu 12.04 LTS and Nvidia driver 304.51. I have remove the nouveau driver with: apt-get --purge remove xserver-xorg-video-nouveau I installed the official nvidia driver (from www.nvidia.com) but when I reboot the PC the resolution of screen is only 640x480 and the monitor is resized. Mo solution at this problem if i change the xorg.conf. Now i have uninstall the nvidia driver and reinstall with sudo apt-get purge nvidia-current sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current When I reboot the screen resolution and size is OK, but if I start nvidia-setting I received the message: You do not appear to be using the NVIDIA X driver. and with command: sudo lshw -c display | grep driver I received configuration: driver=i915 latency=0 This sound like the system is using the Intel card. When I launch command lspci | grep VGA the output is: 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1058 (rev ff) And there is no /etc/X11/xorg.conf. I have read a lot of guides on internet but without success.. How i can use nvidia card with the driver that i have installed?

• Ubuntu 12.04 server froze during the first boot after it was installed.

• Why is my fresh install of 12.04 running slow?

  - by user75129

  Hey guys I'm a new linux user, I figured it would be the best for the laptop I just purchased because it's said to be faster than Windows 7. I'm currently dual-booting with Windows 7 Professial and Ubuntu 12.04. The laptop I am using is the LG X Note P210 Specs: Intel Core i5 470UM Dual Core clocked at 1.33GHz 12.5" HD LED LCD Screen at 1366 by 768 4GB DDR3 @ 1333 MHz RAM Integrated Intel HD Graphics Card 4 Cell Battery with 3150mAh It comes loaded Windows 7 Home Premium 64-Bit, it runs fine on that but my Ubuntu 12.04 runs slower than it and I don't understand why, it definitely has decent specs to run even a 64-bit operating system and do some gaming. Granted I know it's not the best but for a laptop it does the job so Ubuntu should work especially since it's said to make older units with worse specs run even better. I'm not all that familiar with coding and all so what are things I can do to optimize speed without overclocking? Boot up is fine, its program response time I believe, once Im in the actual OS, it lags, slows down, apps stop working, take forever to load up apps.

• How to debug lack of sound in Asus EEE PC

  - by Kalmar

  I have an Asus EEE PC 1225B with fresh Lubuntu 12.04. And no sound. It doesn't seem to be some common problem, so I have to make some research what's up. I tried running alsamixer, so I know I have Realtek ALC269VB with nothing muted unexpectedly. What can I do next to identify and solve the problem?

• SD card won't appear after upgrade to 13.10

  - by Pixel

  My SD card won't mount when I put it into my lap top, everything was fine before the upgrade. The information about the SD card appears just fine when I type "sudo fdisk l " it just says that it doesn't have a valid partition table.

• Ubuntu does not recognize my built-in monitor.

  - by B3tturTh3nU

  I've recently discovered of a boot problem Ubuntu has with my laptop. I have successfully installed Ubuntu on two other computers, and I've never experienced this problem. What happens is, after the live boot CD loads, the screen goes completely blank. Although, I suspected that there was no problem booting, so I loaded with BIOS only, which worked perfectly fine. Of course, not being very proficient with this, I have no idea what needs to be done to fix the problem. I have switchable graphics cards(the ATI Mobility Radeon HD 5650, and some low-end Intel card), and an Intel i5 quad core processor. I was booting with the Ubuntu 10.10 64 bit desktop distribution. If there's any more information you need from me, please let me know. EDIT: I was able to look into this a bit more, thanks to one of the comments provided, and I have some new information. Ubuntu does seem to be able to recognize both of my graphics cards. The problem I found was that, in the Xorg.0 log, it mentions that there were "no screens found." I'm using a notebook, so the screen is built in. Does anyone know of a way to get Ubuntu to recognize the monitor?

• Ubuntu 12.04 and Nvidia GTX 550 Ti

  - by Jim

  OK I'm currently trying to install Ubuntu x64 Server 12.04 onto the following machine: Intel Core i5-2320 3.0GHz LGA1155 6MB 8 GB DDR3 RAM, Gigabyte Z68P-DS3 S1155 Intel Z68 DDR3 ATX M/B, OCZ 60 GB SSD, 3x Samsung 2TB drives in a RAID 5 array (via M/B) Now what I think is causing the issue is the following: EVGA GeForce GTX 550 Ti 951MHz 1GB PCI-Express HDMI FPB As the server CD works in text mode I haven't had a problem with actually installing Ubuntu. Partioned with: 1GB /boot SSD, 59GB / SSD, 10GB swap RAID5, ~4TB /home RAID5 On a straight boot, you briefly see the GRUB menu, followed by a blank screen. The keyboard and mouse blink as they are initialised but no sign of life from the screen. Followed by a bit of research (otherwise known as google) ... Booted in quiet splash nomodeset Now I have a fully working linux distro at the command prompt. I then proceed to try and update the nvidia drivers with apt-get (after updating repositories etc) and rebooting. Still the same problem. I also tried reinstalling from the CD and installing said drivers in the install process before GRUB was installed, still the same symptoms. Does anybody have any solutions? I'm at my wits end here, I bought this machine to be a linux server / tinkering machine and have just spent 4-5 hours trying to just get a basic install working.

• I can't enable extra effects in Ubuntu 10.10. Please help?

  - by jasoncruz98

  I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was Compiz 0.9.6. Now, after installing Ubuntu 10.10, when I first logged in, the graphics were slow. When I dragged a window from one end of the screen to the other, the whole screen would blur up and pixelate and it would be very laggy. I tried going to System Preference Appearance and selecting Extra effects on the Visual effects tab, but all I got was "Desktop effects could not be enabled". I don't know whether I should install the Additional drivers (proprietary) because my Internet is slow and it would take a long time. Furthermore, in Ubuntu 11.10, after I installed the proprietary graphics driver, I immediately went into fallback mode and wasn't even offered an option to set my desktop session to Ubuntu 3D. I didn't need the driver to run Compiz in Ubuntu 11.10, it just ran so smoothly. But in Ubuntu 10.10, everything is so laggy. Should I install the ATI/AMD Proprietary FGLRX Graphics Driver for Ubuntu 10.10 to enable extra effects? Or is there something else wrong with my system?

• Problem with installing Nvidia display drivers on Ubuntu 13.10

  - by Pascal

  Hello everyone and thank you for taking a look at this topic! I'm currently trying out Ubuntu 13.10 but I keep hitting a wall when it comes to installing a driver. I've tried: sudo apt-get install nvidia-current This resulted in a un-bootable system. The screen just stayed black and the cursor displayed as an 'X'. After that I did had to re-install Ubuntu. The computer I'm using is an Acer-Aspire-V3 with a build in Nvidia geforce GT 630M and also with a Intel HD graphics chip-set (not sure if chip-set is the right word here). "lspci | grep VGA" output: pascal@pascal-Aspire-V3-571G:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) I've searched a bit here and there and found out that it would be wise to mention that this laptop is using (or so I think) Nvidia Optimus, not sure if it will add anything to the subject but at least I'll mention it just to be sure. Now to the questions: Q1 How is this caused and how can I fix it? Q2 What additional information could I provide to help you help me?

• WiFi slow sometimes, reboot helps, how do I debug it?

  - by January

  Ubuntu 12.04.1 with all updates installed. Laptop Lenovo Thinkpad X230 with Intel Corporation Centrino Advanced-N 6205. WiFi sometimes becomes extremely slow. Often this occurs when I wake the system from suspend and connect to a different network. I find no obvious clues in system logs. /etc/init.d/network-manager restart doesn't help, but a reboot does. How can I go on with debugging this issue? In specific, which parts of the system should I try to restart (without a complete reboot)? I know of problems with Intel WiFi (see for example this question and the instructions here), but if that was the problem, I would expect the WiFi to be slow at all times, and not just sometimes. Also, I have a gut feeling that it might be a DNS issue (for example, getting a page from a known server is faster than accessing a new server), but I don't know how to tackle it. Update: despite numerous updates in the meanwhile, I still observe this behavior. It happens always when I access my WiFi router at home after returning from work; when I reboot my laptop, the connection speed is good again.

• Ubuntu 12.04 won't shut down - stopping winbind daemon

  - by jan

  My Precise Pangolin sometimes won't shut down - the screen is black with text on it. Mostly last line says something like "stopping winbind deamon" (sometimes also virtualbox, which is above winbind daemon; edit: sometimes the last line says "running unattended updates") and it stays like this for about ten miutes. Then I usually hold the power button for 5s to shut it down. It's very unpredictable - sometimes the computer shuts down without problem and sometimes it hangs. I've tried many ways to shut it down: HW button, panel applet, sudo shutdown -h now, sudo poweroff, sudo halt, etc. even sudo reboot or restart from panel applet have this problem. Sometimes it works ok but every method named hung at least once on the same (damned) line. My specs: FUJITSU SIEMENS LIFEBOOK E8310, Intel Core2 Duo T7300 @ 2.00GHz, 3GB RAM, GPU: Mobile Intel(R) 965 Express Chipset Family Ubuntu 12.04.2 32bit, 3.5.0-41-generic kernel (but it did it on older kernels and 12.04.x systems too). Any ideas what should I try next? Thanks a lot! Jan

• Ubuntu is not detecting my android device

  - by user3514160

• LiveCD/USB boot issues with Ubuntu 12.04 on blank drive

  - by Richek

  Not sure how common this issue is, or even how badly I may be missing something simple, but I am a first time usuer having some serious problems. Some background: old HDD running Windows 7 developed too many bad sectors and is bricked. I'm attempting to install Ubuntu 12.04 on a fresh 1TB drive by booting from a liveCD USB flash drive. I've not been able to get past the initial menu screen, however, as the process stalls out shortly after selecting an option (both boot from drive and install to drive). I've tried multiple USB drives as well as CDs, modified the boot order, flashed BIOS, and even tried booting with only the flash drive and the keyboard connected with the same results.Typically what I observe is that the OS begins what I think is compliling, listing drivers and components before freezing on one. When the keyboard is plugged in, its the keyboard driver, before I flashed BIOS, it was a BIOS related item, now its an unknown entry. The computer seems to be reading the drive (idicated by USB light flashing or CD drive reving) for roughly 10 minutes with no progress, followed by the drives going quiet. Some spec info: Motherboard: ASUS P5Q Pro, BIOS version 2102 (latest version), Intel chipset CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz help would be appriciated!

• How to get Nvidia graphics working on Sony Z laptop?

  - by projectshave

  I have an older Sony VAIO Z 590 laptop with switchable graphics between Intel and Nvidia GeForce 9300M. It is NOT Optimus. I did a clean install of Ubuntu 12.04. Everything works, but it's using Unity 2D with the Intel drivers. I've tried loading the Nvidia drivers from "Additional Drivers", but it says "this driver is activated but not currently in use". When I run "nvidia-settings", an error window pops up to say "You do not appear to be using the NVIDIA X drivers." "lspci" shows both graphics cards. Let me know if I should add more info. How do I get the Nvidia graphics and Unity 3D working?

• Kubuntu not showing eth0

  I just installed Kubuntu 12.04.2 and do not have an internet connection. I also cannot access the Desktop and only have the terminal. When I enter xlcock I get Error: Can't open display:.

• How do I turn off PCI devices?

  - by ethana2

  With the purchase of an Intel SSD and 85WHr Li-ion battery and the linking of wifi and bluetooth to my laptop's wireless switch, extensive Intel PowerTop usage, switching from compiz to metacity, stopping of the desktop-couch daemon, removal of Ubuntu One and several other services from my startup, disabling of everything possible in my BIOS, and physical removal of my optical drive, I've gotten my battery life up fairly high, but I think there's still more to be done. Specifically, when I'm in class taking notes, I want to temporarily but completely power down: Ethernet Firewire USB ports SD card reader Optical drive Webcam Sound card PCMCIA slot ..without turning them off in my BIOS like they are now, if possible, because then I have to restart my computer to use any of them. As it stands, I still haven't managed to power down: Firewire USB connection to webcam sound card How do I tell Linux to disable and power down these devices? Is it true that any PCI slot can be physically powered down? My current idle power consumption is 7.9 watts plus the screen. (10.0W at min. brightness) Also, how do I set the screen timeout to ten seconds? gconf editor isn't honoring it when I set it to that. Will switching from nVidia to Nouveau save any significant amount of power?

• LiveCD not booting/can't install Ubuntu 11.04

  - by user20318

  So, i got a new laptop somedays ago and as usualy, i went formated it to install Ubuntu. Download 11.04 and burned it on my pendrive using my old laptop (running 11.04). When i tryed to boot from the LiveUSB on my new laptop, it just showed me some weird graphics and if i select any option (can't see what im selecting), it gives me a black screen and that is all. Then i tryed to boot with this LiveUSB on my old laptop, and it worked just fine ._. Burned a CD with Ubuntu 11.04 (64bits) and the problem continue. Then i tought it could be my CD Driver, since the laptop is new and all... burned a Windows 7 64 bits DVD and it worked just fine. Also, if i check the CD/Pendrive inside Windows Seven, all the files there are ok. Anyone have any idea of what can be? I found lots of questions about this, but none of them had the weird menus i'm getting ._. oohh... i also get a "prefix is not set" before the weird menu appears :S My sis specs: Intel Core i5 2400 Intel HD 3000 4gb DDR3 If anyone can help, i will be really greatfull ._.

• Screen flickering / scrambling on an Asus UL30A

  Recently my Laptop screen started to flicker. You can view the phenomena here: YouTube Sometimes the screen is totally scrambled, but most of the time it starts with the Title bar only. It happens inconsistently. My Laptop is Asus UL30A and I'm using Ubuntu 11.10.
