Wifi card recognized but not working

I removed old wifi card and replaced with new one. OS is Ubuntu 18.04. The new card’s model is Intel 7260HMW, Intel DualBand Wireless card which supports upto wifi AC. I downloaded right driver from https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html, and placed the .unode driver file into /lib/firmware, as the webpage suggests. Funny thing is that there were already bunch of intel 7260 drivers, maybe because Ubuntu shipped with some popular wifi card driver.

After rebooting, and sudo lshw -C network, terminal says the board recognizes the new chip by showing the chip model. However when ifconfig the wlan0 doesn’t have ip address, and ping 8.8.8.8 also doesn’t work, with message connect: Network is unreachable.

I typed dmesg to see what’s written on kernel log, and the following is shown around 13th second:

iwlwifi 0000:03:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x14 iwlwifi 0000:03:00.0: base HW address: 80:19:34:e2:14:13 ...

I followed the guide here: My WiFi adapter is not working at all, how to troubleshoot? I had no soft link nor hard link when rfkill list, and the guide didn’t work.

I’d really appreciate if someone helps me 🙂

GPU model not recognized in Additional Drivers tab

I am looking to install Nvidia’s proprietary drivers in order to be able to use CUDA for some Machine Learning.

But I am not able to select the proprietary driver option as the GPU model is not recognized in Software & Updates under the additional drivers tab: It only says Nvidia Corporation: Unknown

But if I lookup the GPU through a lspci command, it is detected correctly: It is indeed a GTX1660

Does someone know why that is the case?

partitions setup in Fedora, want to keep them, but root is not recognized

I’ve seen comments that claim all I need to do is change the name of the partition from “root” to “/” – cool, HOW?

I am looking at the [!!] Partition disks page of the Ubuntu Server amd64 install and I just don’t get the interface. HOW does one rename a partition? Is it really accepting the partitions that are already defined? Fedora doesn’t, you have to re-enter them every time even when it sees an existing install & partition table (29 releases and they haven’t made that any easier to use?).

Recognized but no sound with Asus Xonar SE in Ubuntu 19.04

Recently I have bought the Asus Xonar SE in order to use S/PDIF devices for playback. It was the newest and best I could find for the price, and people on Amazon commented it worked in Ubuntu for them (read about 12.04 & 14.04 being OK). Now, I don’t know how they did it, but I can’t get it to work. I have tried many things told about for troubleshooting and solving audio-related problems similair to mine on Ubuntu/Linux, but nothing so far.

I would like to use the S/PDIF output, but also by trying with the analog output on the card had no luck: I have seen no playback.

The card itself is a bit weird. It uses a USB (yes, even though it’s PCIe) audio processor from C-Media (the CM6620A), a host controller for USB from AsMedia (ASM1042A) and the S1220A from Realtek as a DAC.

Asus their soundcard works perfectly in Windows 10 (my PC is dualbooted with REFInd), after having installed the software from the CD Asus provided (so there’s no hardware problem there)

Now software (steps):

I have set the output device correctly in the Ubuntu settings panel for sound (it looks like this: https://imgur.com/a/AfJN7ls ). I have also tried changing to different digital profiles in a PulseAudio tool, but no luck with that either.

I already worked with Alsamixer in the terminal and tried solving the issue with f.e. muted volume, but no luck there. This is what it looks like now: https://imgur.com/a/fLIotEY To me it mainly looks odd that none of the outputs are correctly labelled, as they are with working (normal) cards in Alsamixer. It’s all “PCM …”

Another thing I tried was doing a search on the codecs on the machine, and there it returned this:

==> /proc/asound/card0/codec#0 <== Codec: Realtek ALC892  ==> /proc/asound/card0/codec#2 <== Codec: Intel Kabylake HDMI 

From the return of aplay -l I can see that the Xonar SE is card#1 , but for that there are no codecs available via the command I ran like above (= head -n 1 /proc/asound/card*/codec#*).

aplay-l output:

**** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 1: SoundCard [Xonar SoundCard], device 0: USB Audio [USB Audio]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 1: SoundCard [Xonar SoundCard], device 1: USB Audio [USB Audio #1]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 1: SoundCard [Xonar SoundCard], device 2: USB Audio [USB Audio #2]   Subdevices: 1/1   Subdevice #0: subdevice #0 card 1: SoundCard [Xonar SoundCard], device 3: USB Audio [USB Audio #3]   Subdevices: 1/1   Subdevice #0: subdevice #0 

The full Alsa information output it produced seems fairly complicated to me. I find it difficult to get information from there, but I have the output here: http://alsa-project.org/db/?f=2a945544a53708b95cd185596fd636a60f1c1e62

Btw: I also tried it with a different Ubuntu version (18.04 LTS from USB) and also Mint 19.2. No luck with that either, same result like all of the above information.

Is there anyone who knows what steps I can take to make this work? Or how to diagnose a problem?

Thanks already

q key not recognized

I have an ASUS ROG G752-VSK gaming laptop that I recently installed Ubuntu on. During the installation, keyboard did not work so I had to plug an external USB keyboard to finish the installation.

After booting up, I noticed that the keyboard started working again however this time the functionality keys and backlighting was not working, also the q key stopped working completely.

Considering it a kernel issue, I went ahead and manually updated to the latest Linux kernel. This fixed the backlighting and function keys, however the q key remains non-functional.

I’ve done a few different troubleshooting attempts, and tried out basically a ton of different suggestions:

  1. Important to note, the keypress is not being detected.

I tried out xev,scancodes, etc, updated the system, upgraded all apps and other different ways, installed some old packages for reconfiguring the keyboard, changed the keyboard locale multiple times, went in the dkpg keyboard utilities. Changed system settings, even messed with ACPI parameter and GRUB settings. Nothing I ever did indicated any response from key.

This is not a hardware issue, this key has been working yesterday on W10.

Anyone have any idea on how to fix this?

External HDD works on desktop but not recognized on laptop

My 1 Tb external HDD is not seen by my laptop but woks fine on my desktop.

Laptop is running Ubuntu 18.04.2

Desktop is running Xubuntu 18.04.2

HDD also works on Windows and Mac machines, so the issue is with the laptop, not the HDD.

On the Laptop:

lsusb shows the HDD is listed as a device.

fdisk -l does not list the HDD

gparted does not see the HDD either.

USB memory sticks work and automount as expected.

My problem seems a little like this guys problem, but I’m not sure if I understand his solution, or if it would work for me: https://www.linuxquestions.org/questions/linux-hardware-18/external-usb-hard-drive-not-detected-bu-usb_storage-4175575404/

How can I successfully mount my external HDD on my laptop?
