• Getting wireless to work on Ubuntu 11.10 (on a mac machine)

  - by yayu

  I have a 2008 white 13.3 inch macbook that now solely runs ubuntu. However, I cannot get wifi or cable to work on it. Regarding the cable, it atleast tries to connect but eventually disconnects from the wired network. Here is the output for lspci (pastebin) I tried installing b43-fwcutter and firmware-b43 but get errors. (I loaded them from a thumb drive and tried sudo dpkg -i). I cannot understand these instructions from the documentation, as I cannot locate the pool directory. b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online. Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

• Hard disk error

  - by Nadim A. Hachem

  I got this error during installation. "The installer encountered an error copying files to the hard disk: [Errno 5] Input/output error This 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." how can i fix this and what does it mean specifically? i'm installing via usb so it can't be the CD. the laptop is recent so it cant be an old HD.

• Only one resolution available in Xorg.conf

  - by Kévin Guilbeault

  I recently upgraded to Ubuntu 12.10 and when I try to change my resolution in NVIDIA X server settings, I only get the native one (1600x900). When I had 12.04 installed, all resolutions were available in the drop down list. My goal is to have twinview working again. I used to set my two screens to twinview and clones, using my HDTV resolution (1360x768) which was previously available in 12.04 for my laptop screen too. In 12.10, I tried to install all of the NVIDIA drivers available except the nouveau driver. I tried to add a new mode using Xrandr --newmode / --addmode, but it didn't work; it coudn't detect my output. I'd like to know if this is a known bug and if there's something to do with that. Thanks!

• pulseaudio: no microphone configuration

  - by mitsch

  Updated Ubuntu to precise from oneiric on a Dell Inspirion Mini 10 (with an Intel HDA-Soundcard). I can't remember having any issues with the microphone. I didn't need it - I tried ekiga the first time in precise. I couldn't hear any sound in the echo test of ekiga, so I switched to the "System Preferences" and looked for the microphone to boost it. Surprisingly, the microphone input was greyed out - I couldn't mute or unmute, i couldn't even move the volume-slider. On the other hand: I could change the microphone-setting on console with alsamixer, so don't worry about that… :) I just wanted to ask, how to get pulseaudio back to the known, comfortable behaviour. Some newbies won't know the trick to use alsamixer… My soundcard (output of lspci): 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Greets!

• Why isn't garbage collection being activated in my code? [migrated]

  - by Netmoon

  I have a foreach statement in my code, where each iteration calculates huge amounts of data and goes to the next iteration. I run this code, but when I read the log, I see there's a memory leak error. PHP.net says when this happens, using gc_enabled() is a good way to handle this. I've added these lines to last line of the foreach block: echo "Check GC enabled : " . gc_enabled(); echo "Number of affected cycles : " . gc_collect_cycles(); And this is the output: Check GC enabled : 1 Number of affected cycles : 0 Why do cycles exist, but the affected cycles is 0?

• How do I get a matching theme when I run a program as root?

  - by NES

  I use a Metacity theme in my Ubuntu installation. Unfortunately it isn't activated for programs with Gui that are started as root user and some other other certain programs like gufw (when i start gufw by commandline not as root)? It uses an old not very eyecandy Theme. For example for Gufw is gives the following output on commandline: /usr/share/themes/Finery/gtk-2.0/gtkrc:365: error: unexpected number `0', expected number (float) /usr/share/themes/Finery/gtk-2.0/gtkrc:365: error: unexpected number `0', expected number (float) What could be the reason, is there a way how to enable this theme also for these programs?

• SSD becomes hot, disk failure warning

  - by Aegluin

  I have a two weeks old SSD (Kingston SSDnow 64GB). Yesterday, the computer shutdown twice and after rebooting I was bombarded with disk failure warnings. I usually take such warnings serious (and backed up), but skeptical. After cooling down, the laptop boots again and the only red Smart value was the temperature (Ubuntu did not show the temperature of failure, but the at that time 29°). After refreshing the Smart status and doing a "self test", everything is green. Before contacting Kingston support, I would like to know whether it could be due to a software issue: Is it possible that it is false alarm, and how can I check? I installed Ubuntu 12.04 32bit and took care of alignment. I supposed Ubuntu set up with optimal settings for SSDs, how can I check that there was no mistake? The current temperature is around 40-56°. Is such a temperature abnormal for SSDs? Output of sudo smartctl --all /dev/sda: http://pastebin.ubuntu.com/1175940/

• Weird issue with iptables redirection

  - by skypemesm

  I am trying to redirect all incoming traffic on UDP port 5060 to port 56790, and all outgoing traffic from 5060 to the port 56789. I used these iptables rules: iptables -t nat -I PREROUTING -p udp ! -s localhost --dport 5060 -j REDIRECT --to-port 56790 iptables -t nat -I OUTPUT -p udp ! -s localhost --sport 5060 -j REDIRECT --to-port 56789 I listen on both ports using RAW SOCKETS after setting the interface to PROMISCUOUS mode using ioctl. I see packets ONLY on 56789 i.e.SENDING side, and I do not see any packets on 56790, while wireshark shows that many packets are delivered to port 5060. Why would this happen? Any ideas? Do you think it's a problem with iptables rules or something to do with raw sockets? [This is ubuntu 10.04 and iptables v1.4.4]

• How can I use smbclient to connect to Windows shares by hostname when a firewall is enabled?

  - by skyblue

  I can't connect to file shares on Windows computers using smbclient -L //hostname when the firewall is enabled. This occurs whether I'm using ufw (which allows outgoing traffic and replies back in with the default configuration) or iptables (where I'm allowing outgoing traffic and replies back in with iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT). However, smbclient -L //ip-address works whether the firewall is enabled or not. I also tested this against a Samba server running on Ubuntu and again smbclient -L //hostname does not work when the firewall is enabled, but smbclient -L //ip-address works whether the firewall is enabled or not. For reference, here are the iptables rules I used during testing: *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -d 224.0.0.251/32 -p udp -m udp --dport 5353 -j ACCEPT COMMIT

• How can I change resolution of "my video" in Skype?

  - by koushik

  I have a logitech Quickcam Pro 9000 connected to my ubuntu desktop and it works fine with Skype. However, Skype inputs and sends my video at the native (for the webcam I think) resolution of 1600 x 1200. I can confirm that the camera supports a wide variety of resolutions starting from 160 x 120 upto 1600 x 1200 (including e.g., 320 x 240, 352 x 288) using cheese. I can select these resolutions and see the output is appropriately scaled. Also, I don't see any improvements in smoothness of motion in the captured video so I suspect the original 1600 x 1200 is scaled down in the path somewhere. Is it possible to somehow to enable this scaling capability towards Skype?

• How do I figure out the minimum number of swaps to sort a list in-place?

  - by sova

  In-place sorting is essentially swapping elements without using extra storage, correct? How can I find the minimum number of swaps required for a list? A C D Q R Z E // input | | | > > > <<< // movement A C D E Q R Z // output Swapping: A C D Q R Z E swap Q with E, ACDERZQ swap R with Q, ACDEQZR swap R with Z, ACDEQRZ. done. 3 swaps. Shifting items left or right is essentially swapping, but I want the optimal number for plucking an item out of line and switching its place with another.

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

• Bumblebee optirun appears to depend on Intel

  - by user206398

  I have a Lenovo T420 with Intel and Nvidia graphics. On upgrade to Ubuntu Saucy, I had to purge and reinstall bumblebee-nvidia to get beyond optirun failing to find a GPU driver. Now, "optirun glxgears" and "optirun sol" succeed, but optirun fails on 2 Virtual Life viewers that it supported in the past, Cool VL (CoolVLViewer-1.26.8.34-Linux-x86) and Imprudence (Imprudence 1.4.0 beta2). In both cases, the error output is huge, but it starts with libGL error: failed to load driver: i965 and libGL error: failed to load driver: swrast From the little I can discover, i965 is an Intel graphics driver, which should not be invoked at all. I haven't found any information about swrast. I suspect that some of the X configuration associated with Bumblebee has some Intel dependence that is invoked on certain library calls, but not others. I haven't discovered any definite information on this line. The Cool VL Viewer runs without optirun, but complains about the insufficiency of the Intel graphics.

• Optical Character Recognition software recommendations?

  - by Tim

  I have seen some ebooks/papers that were apparently scanned from their paper versions but the text in the ebooks/papers can amazingly be copied out. I suppose the directly-scanned versions must have been processed by some Optical Character Recognition software. So I would like to know what are the recommended Optical Character Recognition softwares? Especially those that are either for Ubuntu or free? If those for Windows are far more superior, please let me know as well. I am particularly interested in those OCRs that can accept a scanned pdf file as input and still produce as output another pdf file that looks the same as the input one but with its text copyable. Thanks and regards! Please limit one software per answer

• Monitor not recognised after apt-get upgrade on 11.10 - maximum 1024x768 resolution
