• Loading latest firmware iwlwifi-6000

  - by grzeh

  I just installed 11.10 on Dell XPS 15z. Somebody know why kernel does not load the latest firmware for wifi Intel Centrino Advanced-N 6230. $ modinfo iwlagn |grep iwlwifi-6000 firmware: iwlwifi-6000g2b-5.ucode firmware: iwlwifi-6000g2a-5.ucode firmware: iwlwifi-6000-4.ucode In package linux-firmware there is latest version (iwlwifi-6000g2b-6.ucode) $ dpkg -L linux-firmware | grep iwlwifi-6000 /lib/firmware/iwlwifi-6000-4.ucode /lib/firmware/iwlwifi-6000g2a-5.ucode /lib/firmware/iwlwifi-6000g2b-5.ucode **/lib/firmware/iwlwifi-6000g2b-6.ucode**

• iwlwifi on lenovo z570 disabled by hardware switch

  - by Kevin Gallagher

  It was working fine with windows 7. The hardware switch is not disabled. I've toggled it back and forth dozens of times. The wifi light never turns on and it always lists as hardware disabled. I have the latest updates installed. I've been searching for solutions, but none of them seem to work for me. I've tried removing acer-wmi. I've tried setting 11n_disable=1. I've tried resetting the bios. I've tried using rfkill to unblock (only removes soft block). I've rebooted dozens of times. The wifi light turns off as soon as grub loads. Edit: I have a usb edimax wireless nic. It shows hardware disabled as well (although rfkill lists as unblocked). If I unload iwlwifi the usb nic works fine. uname -a `Linux xxx-Ideapad-Z570 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linu`x rfkill list 19: phy18: Wireless LAN Soft blocked: no Hard blocked: yes dmesg [43463.022996] Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree: [43463.023002] Copyright(c) 2003-2011 Intel Corporation [43463.023107] iwlwifi 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [43463.023190] iwlwifi 0000:03:00.0: setting latency timer to 64 [43463.023253] iwlwifi 0000:03:00.0: pci_resource_len = 0x00002000 [43463.023257] iwlwifi 0000:03:00.0: pci_resource_base = ffffc900057c8000 [43463.023261] iwlwifi 0000:03:00.0: HW Revision ID = 0x0 [43463.023797] iwlwifi 0000:03:00.0: irq 43 for MSI/MSI-X [43463.024013] iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Wireless-N 1000 BGN, REV=0x6C [43463.024250] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [43463.045496] iwlwifi 0000:03:00.0: device EEPROM VER=0x15d, CALIB=0x6 [43463.045501] iwlwifi 0000:03:00.0: Device SKU: 0X50 [43463.045504] iwlwifi 0000:03:00.0: Valid Tx ant: 0X1, Valid Rx ant: 0X3 [43463.045542] iwlwifi 0000:03:00.0: Tunable channels: 13 802.11bg, 0 802.11a channels [43463.045744] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

• No more internet connection after update in 14.04 with Intel Dual Band Wireless AC 7260

  - by luis

  My Dell XPS 15 (haswell) was working fine until I stupidly accepted recently to apply Ubuntu updates. Since then, my wifi does not work (it shows "device not managed" when clicking wifi icon in toolbar). Even USB to Ethernet adapter does not seem to work. Bluetooth at least "sees" other bluetooth devices around... See below output from dmesg (dmesg |grep iwl) : [ 886.462459] iwlwifi 0000:06:00.0: irq 51 for MSI/MSI-X [ 886.462561] iwlwifi 0000:06:00.0: Direct firmware load failed with error -2 [ 886.462562] iwlwifi 0000:06:00.0: Falling back to user helper [ 886.463284] iwlwifi 0000:06:00.0: loaded firmware version 22.1.7.0 op_mode iwlmvm [ 886.475345] iwlwifi 0000:06:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144 [ 886.475433] iwlwifi 0000:06:00.0: L1 Enabled; Disabling L0S [ 886.475684] iwlwifi 0000:06:00.0: L1 Enabled; Disabling L0S [ 886.689214] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' Below the output from modinfo iwlwifi: filename: /lib/modules/3.13.0-29- generic/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko license: GPL author: Copyright(c) 2003-2013 Intel Corporation <[email protected]> version: in-tree: description: Intel(R) Wireless WiFi driver for Linux firmware: iwlwifi-100-5.ucode firmware: iwlwifi-1000-5.ucode firmware: iwlwifi-135-6.ucode firmware: iwlwifi-105-6.ucode firmware: iwlwifi-2030-6.ucode firmware: iwlwifi-2000-6.ucode firmware: iwlwifi-5150-2.ucode firmware: iwlwifi-5000-5.ucode firmware: iwlwifi-6000g2b-6.ucode firmware: iwlwifi-6000g2a-5.ucode firmware: iwlwifi-6050-5.ucode firmware: iwlwifi-6000-4.ucode firmware: iwlwifi-3160-7.ucode firmware: iwlwifi-7260-7.ucode srcversion: 1E6912E109D5A43B310FB34 alias: pci:v00008086d0000095Asv*sd00005490bc*sc*i* (a pack of lines of kind "alias: pci:xxxxx...." that I guess are not helpful) alias: pci:v00008086d0000095Bsv*sd00005290bc*sc*i* depends: cfg80211 intree: Y vermagic: 3.13.0-29-generic SMP mod_unload modversions signer: Magrathea: Glacier signing key sig_key: 66:02:CB:36:F1:31:3B:EA:01:C4:BD:A9:65:67:CF:A7:23:C9:70:D8 sig_hashalgo: sha512 parm: swcrypto:using crypto in software (default 0 [hardware]) (int) parm: 11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint) parm: amsdu_size_8K:enable 8K amsdu size (default 0) (int) parm: fw_restart:restart firmware in case of error (default true) (bool) parm: antenna_coupling:specify antenna coupling in dB (defualt: 0 dB) (int) parm: wd_disable:Disable stuck queue watchdog timer 0=system default, 1=disable, 2=enable (default: 0) (int) parm: nvm_file:NVM file name (charp) parm: bt_coex_active:enable wifi/bt co-exist (default: enable) (bool) parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default: 0) (int) parm: power_save:enable WiFi power management (default: disable) (bool) parm: power_level:default power save level (range from 1 - 5, default: 1) (int) I downloaded the latest versions of iwlwifi firmware from git (git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git; copy iwlwifi-3160-9.ucode iwlwifi-7260-9.ucode iwlwifi-7265-9.ucode to /lib/firmware and reboot) but as you can imagine it did not help.

• Wireless not working on Dell XPS 17 after installing 12.04

• Wifi disabled for Intel Centrino Wireless-N 1000 Intel in 12.04

  - by new_bie

  Laptop model - HP- dm4 - 2070. I had faced the same problem for wireless being disabled in case of 11.10. It had to do with the new kernel. I thought with 12.04 this problem will be handled but the problem persists. Is there no way to get the wireless working except for the way mentioned in the following link ??

• Intel Dual Band Wireless-AC 7260 keeps dropping wifi

  - by Rick T

  My wifi Intel Dual Band Wireless-AC 7260 keeps dropping wificonnection drops and the network to which I was connected disappears from the list of available networks in network manager. The only way to fix it is to disable wifi and re-enable it How can I fix this. I'm using ubuntu 14.04 64bit. It mostly drops connections on the 5ghz network. My other devices don't drop connections over wifi. see logs and versions rt@simon:~$ uname -a Linux simon 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux rt@simon:~$ rt@simon:~$ dmesg | grep iwl [ 3.370777] iwlwifi 0000:03:00.0: irq 46 for MSI/MSI-X [ 3.381089] iwlwifi 0000:03:00.0: loaded firmware version 22.24.8.0 op_mode iwlmvm [ 3.414637] iwlwifi 0000:03:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144 [ 3.414695] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 3.414913] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 3.630208] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' [ 9.304838] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 9.305068] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 605.483174] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S [ 605.483396] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S rt@simon:~$ cat /var/log/syslog | grep -e iwl -e 80211 | tail -n25 Aug 14 08:13:02 simon kernel: [ 3.452780] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:13:02 simon kernel: [ 3.630208] ieee80211 phy0: Selected rate control algorithm 'iwl-mvm-rs' Aug 14 08:13:06 simon NetworkManager[1125]: <info> rfkill1: found WiFi radio killswitch (at /sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0/ieee80211/phy0/rfkill1) (driver iwlwifi) Aug 14 08:13:06 simon NetworkManager[1125]: <info> (wlan0): using nl80211 for WiFi device control Aug 14 08:13:06 simon NetworkManager[1125]: <info> (wlan0): new 802.11 WiFi device (driver: 'iwlwifi' ifindex: 3) Aug 14 08:13:06 simon kernel: [ 9.304838] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S Aug 14 08:13:06 simon kernel: [ 9.305068] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S Aug 14 08:14:18 simon kernel: [ 81.230162] cfg80211: Calling CRDA to update world regulatory domain Aug 14 08:14:18 simon kernel: [ 81.232330] cfg80211: World regulatory domain updated: Aug 14 08:14:18 simon kernel: [ 81.232332] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Aug 14 08:14:18 simon kernel: [ 81.232333] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:14:18 simon kernel: [ 81.232334] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:14:18 simon kernel: [ 81.232335] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Aug 14 08:14:18 simon kernel: [ 81.232336] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:14:18 simon kernel: [ 81.232337] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:23:02 simon kernel: [ 605.483174] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S Aug 14 08:23:02 simon kernel: [ 605.483396] iwlwifi 0000:03:00.0: L1 Disabled; Enabling L0S Aug 14 08:23:18 simon kernel: [ 621.223905] cfg80211: Calling CRDA to update world regulatory domain Aug 14 08:23:18 simon kernel: [ 621.228945] cfg80211: World regulatory domain updated: Aug 14 08:23:18 simon kernel: [ 621.228950] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Aug 14 08:23:18 simon kernel: [ 621.228954] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:23:18 simon kernel: [ 621.228956] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:23:18 simon kernel: [ 621.228959] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Aug 14 08:23:18 simon kernel: [ 621.228961] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Aug 14 08:23:18 simon kernel: [ 621.228963] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)

• Can not connect to wireless on 12.04 with Intel WiFi Link 5100

  - by WiData

  I am having problem in connecting to wifi. I have dual boot (Windows 7 and Ubuntu 12.04) on my Dell Studio 15. I upgraded to 12.04 quite some time ago (at least one month) from 11.10. Everything was working fine till yesterday. Since yesterday I can see the list of available Wifi connection but does not connect to any or if connects (after hours of trying) then disconnects after few minutes. My wifi interface is Intel WiFi Link 5100 AGN. However the problem is on both Windows and Ubuntu. Here are outputs of some commands which may be useful for those interested in helping: ~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:22:19:fa:65:bb UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:794 errors:0 dropped:0 overruns:0 frame:0 TX packets:794 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:56280 (56.2 KB) TX bytes:56280 (56.2 KB) wlan0 Link encap:Ethernet HWaddr 00:22:fb:d2:fc:ce UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:239 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:53603 (53.6 KB) Here is the output for the command sudo lshw -C network *-network description: Wireless interface product: WiFi Link 5100 vendor: Intel Corporation physical id: 0 bus info: pci@0000:04:00.0 logical name: wlan0 version: 00 serial: 00:22:fb:d2:fc:ce width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-48-generic-pae firmware=8.83.5.1 build 33692 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn resources: irq:47 memory:f8000000-f8001fff My kernel version is kernel version 3.2.0-48-generic-pae I also checked this post which was helpful.

• How do I prevent missing network from slowing down boot-up?

  I have been having rather slow boot on Ubuntu 12.04. Lately, I tried to figure out the reason and it seems to be the network connection which does not get connected and requires multiple attempts.

• Slow boot on Ubuntu 12.04, probable cause the network connection

• Ubuntu 11.10 to 12.04 results in loss of N network capability - how to restore?

  - by user74273

  On Ubuntu 11.10, I had zero issues with N network detection and speed. I cannot remember whether the old driver was iwlagn or iwlwifi. This was with Ubuntu repository Linux kernel 3.0.0-22. Upon upgrading to Ubuntu 12.04, iwlwifi is the available driver and while it detects N networks, upon connection, the speed is cripplingly low and DNS look-ups do not occur (impossible to browse). This is with Ubuntu repository Linux kernel 3.2.0-26. Please note that the 11n_disable flag for the iwlwifi module cannot work for me as I require N network access. Is there another solution? Perhaps, is there a way to easily patch the new kernel with the old wireless module (just copy-and-paste the iwlagn module into the new kernel source and re-compile)? Relevant hardware specs: Dell Inspiron N5110 Network Adapter: Intel® Centrino® Wireless-N 1030

• After connecting wlan0 to bridge interface (and then removing it), can't connect to AP

  - by gmonk

  I'm on a laptop running Debian Jessie with kernel 3.13-1-amd64; lspci shows that my wireless NIC + driver is 04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 3160 Kernel driver in use: iwlwifi This has been working without any problems, until I tried creating a bridge for lxc containers to use. I did the same thing as this person here: How-to set up a network bridge on a laptop for LXC use? -- and ended up having the same problem as this poster did, so I decided to "undo" my actions. This hasn't been successful.

I'm not sure what I did wrong, or what step I've skipped in trying to get wlan0 back as a non-bridged device -- I removed it from the bridge and then deleted the bridge itself. Any ideas?

• Need help with chronic slow wifi connections

  - by mgeorge

  I have had chronic slow wifi connections on several networks for a while now, I think since my update to 12.04 when it came out. I have tried many of the tips and tricks already available out there in the forums with no luck (wicd, etc..). I want to see if any of you experts out there might be able to help me, and thanks in advance!! I use ubuntu 12.04 on a lenovo ideapad y650, and most networks I connect to lose the connection frequently or do not give appropriate bandwidth when I am connected.

• Yoga Pro 2 Wi-Fi not working

  - by user293004

  I installed Ubuntu 14.04 on my new Yoga Pro 2 and the wireless is not working. It started with Windows 8 on it. The Network Manager says Wi-Fi is disabled by hardware switch. I tried putting a blacklist file in ect/modprobe.d as has been suggested in many places. I called the file "blacklist-ideapad_laptop.conf" and wrote in the file blacklist ideapad_laptop I checked to make sure that the wireless is enabled in the BIOS. It is. I ran rfkill list all and it displayed: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes I ran iwlist wlan0 scan and it displayed: wlan0 Failed to read scan data : Network is down I ran sudo rmmod ideapad_laptop and it displayed: rmmod: ERROR: Module ideapad_laptop is not currently loaded. I ran ifconfig wlp1s0 up and it displayed: wlp1s0: ERROR while getting interface flags: No such device. I ran "lspci" and it displayed: 01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b) I ran sudo lshw -c network and it displayed: *-network DISABLED description: Wireless interface product: Wireless 7260 vendor: Intel Corporation physical id: 0<br> bus info: pci@0000:01:00:0.0 logical name: wlan0 version: 6b serial: 7c:7a:91:5f:9b:fa width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.13.0-24-generic firmware=22.24.8.0 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:61 memory:b0400000-b0401fff This No wireless with Intel Centrino Advanced-N 7260 seems to be dealing with a similar issue. It suggests that I need to update my firmware. So I downloaded iwlwifi-7260-ucode-23.214.9.0 from Intel's website. I put the file "iwlwifi-7260-9.ucode" in /lib/firmware and ran "sudo lshw -c network" again. It displayed exactly as before. Is there something else I need to do install the new firmware?

• Load old kernel module while keeping current

  - by legion

  So I was wondering if there is anyway that I would be able to load an old iwlwifi from a 2.6 kernel while still using the 3.2 kernel and if there was a guide to doing so? I need to be able to do so because my wireless card is.... well the new kernels have broken all support for my card, which is a Intel Ultimate-N 6300. I'm extremely upset with how badly they broke support for this card to the point where I can't connect to any router that isn't wifi N enabled and even then only a select few routers work, it amazes me as to how awful it is and whats more amazing is how well it worked in 2.6 kernels. I've tried all the work arounds that have been discussed to try and fix this, and the only thing I have found that works is running a 2.6 kernel. However I would like to be able to keep my 3.2 kernel and just load up an old version of iwlwifi that actually supports it, is there anyway to do this?

• Why does my laptop resume immediately after suspend?

  - by Igor Zinov'yev

  I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er Pavilion laptop (Intel Core 2 Duo). Here are the relevant log sections: kern.log: Jun 1 10:42:21 igor-laptop kernel: [ 2225.131171] PM: Syncing filesystems ... done.

  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:. I believe this is because I do not have the correct drivers and need to download them ... using the internet which I can't access.

• WIFI/LAN not working after Installing Ubuntu 13.10

  - by user183025

  I can't connect to my WIFI after installing Ubuntu 13.10. I tried re-installing it three times (thinking that I did something wrong during the installation) but I still can't connect to my WIFI. It just gives me the message that I'm offline and that I can't connect to my WIFI. I also tried connecting to the internet using LAN cable but with the same results. I tried google but it seems that there's no solution to this yet.... Anybody knows how to solve this? Thanks!

• OpenGL (glx) not working with ubuntu 12.10

  - by user26766

  It all started when I installed nvidia's own (download from website) driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode. Here are some outputs: glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig glxgears Error: couldn't get an RGB, Double-buffered visual optirun glxgears works fine lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff) Here's the content of log file when just after running glxinfo: less /var/log/Xorg.0.log | grep gl [ 112.156] (II) LoadModule: "glx" [ 112.157] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so [ 112.157] (II) Module glx: vendor="X.Org Foundation" [ 112.157] (II) UnloadModule: "glx" [ 112.157] (II) Unloading glx [ 112.157] (EE) Failed to load module "glx" (module requirement mismatch, 0) Some more info... lsmod Module Size Used by bbswitch 13612 0 pci_stub 12623 1 vboxpci 23195 0 vboxnetadp 25671 0 vboxnetflt 23480 0 vboxdrv 320372 3 vboxpci,vboxnetadp,vboxnetflt parport_pc 32689 0 ppdev 17074 0 bnep 18141 2 rfcomm 46620 12 binfmt_misc 17501 1 snd_hda_codec_hdmi 32049 1 snd_hda_codec_realtek 78147 1 joydev 17458 0 uvcvideo 76750 0 videobuf2_core 32852 1 uvcvideo videodev 120310 2 uvcvideo,videobuf2_core videobuf2_vmalloc 12861 1 uvcvideo videobuf2_memops 13405 1 videobuf2_vmalloc snd_hda_intel 33492 3 coretemp 13401 0 kvm_intel 132760 0 arc4 12530 2 snd_hda_codec 134213 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel kvm 414111 1 kvm_intel iwlwifi 386837 0 i915 520799 2 snd_hwdep 17699 1 snd_hda_codec snd_pcm 96668 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec psmouse 100389 0 drm_kms_helper 49113 1 i915 ghash_clmulni_intel 13221 0 snd_seq_midi 13325 0 snd_rawmidi 30513 1 snd_seq_midi btusb 22475 0 drm 288436 3 i915,drm_kms_helper serio_raw 13216 0 snd_seq_midi_event 14900 1 snd_seq_midi snd_seq 61555 2 snd_seq_midi,snd_seq_midi_event mac80211 535936 1 iwlwifi bluetooth 209249 22 bnep,rfcomm,btusb snd_timer 29426 2 snd_pcm,snd_seq snd_seq_device 14498 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78921 16 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device cfg80211 206797 2 iwlwifi,mac80211 aesni_intel 51038 1 cryptd 20404 2 ghash_clmulni_intel,aesni_intel aes_x86_64 17256 1 aesni_intel dell_wmi 12682 0 sparse_keymap 13891 1 dell_wmi dcdbas 14439 0 i2c_algo_bit 13414 1 i915 microcode 22804 0 lpc_ich 17062 0 soundcore 15048 1 snd snd_page_alloc 18485 2 snd_hda_intel,snd_pcm video 19391 1 i915 mac_hid 13206 0 wmi 19071 1 dell_wmi mei 40691 0 lp 17760 0 parport 46346 3 parport_pc,ppdev,lp ahci 25721 3 libahci 31192 1 ahci atl1c 41102 0 how can I fix this? any ideas?

The most relevant post I found on the web was this: http://ubuntuforums.org/archive/index.php/t-1722306.html Here it's explained that the problem is with the priority of shared libraries that are loaded for glxinfo. Here's what I get when I look up the libraries: linux-vdso.so.1 => (0x00007fff6bf8b000) libGL.so.1 => /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 (0x00007f22d6ccd000) libX11.so.6 => /usr/lib/x86_64-linux-gnu/libX11.so.6 (0x00007f22d6993000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f22d65d3000) libglapi.so.0 => /usr/lib/x86_64-linux-gnu/libglapi.so.0 (0x00007f22d63ad000) libXext.so.6 => /usr/lib/x86_64-linux-gnu/libXext.so.6 (0x00007f22d619b000) libXdamage.so.1 => /usr/lib/x86_64-linux-gnu/libXdamage.so.1 (0x00007f22d5f97000) libXfixes.so.3 => /usr/lib/x86_64-linux-gnu/libXfixes.so.3 (0x00007f22d5d91000) libX11-xcb.so.1 => /usr/lib/x86_64-linux-gnu/libX11-xcb.so.1 (0x00007f22d5b8f000) libxcb-glx.so.0 => /usr/lib/x86_64-linux-gnu/libxcb-glx.so.0 (0x00007f22d5977000) libxcb.so.1 => /usr/lib/x86_64-linux-gnu/libxcb.so.1 (0x00007f22d5759000) libXxf86vm.so.1 => /usr/lib/x86_64-linux-gnu/libXxf86vm.so.1 (0x00007f22d5553000) libdrm.so.2 => /usr/lib/x86_64-linux-gnu/libdrm.so.2 (0x00007f22d5346000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f22d5129000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f22d4f25000) /lib64/ld-linux-x86-64.so.2 (0x00007f22d6f54000) libXau.so.6 => /usr/lib/x86_64-linux-gnu/libXau.so.6 (0x00007f22d4d20000) libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007f22d4b1a000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f22d4911000) It seems "mesa" instead of nvidia-current is being used. However I didn't find any obvious link to /lib/nvidia-current in /etc/ld.so.conf (where the directories containing the shared libraries are listed). I don't know if there's anything missing or if this is normal. thanks, UPDATE: The problem was solved by updating to Ubuntu 13.04. It seems bumblebee was to blame, but I'm not sure what was going wrong...

• Intel Centrino Wireless-N 1000 Again ! Ubuntu 13.04 x64

  - by vafa

  First I have to say that I tried everything written about this concept. The problem is that it stops working randomly in 3 main forms : 1 - sometimes it disconnect from wireless network and reconnect automatically 2 - sometimes it disconnect and wont connect no matter what (needs reboot) 3 - some times it's still connected but cannot ping or surf or whatever. I already tried disabling N mod using these commands : sudo modprobe -r iwlwifi modprobe iwlwifi 11n_disable=1 (or 0, whatever) it didn't help . these are the results of lspci, sudo lshw -C network, ifconfig, iwconfig, rfkill list when it disconnected and didn't connect till reboot : ifconfig : eth0 Link encap:Ethernet HWaddr c8:0a:a9:34:65:77 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX
