Dell Inspiron 3538 (with Qualcomm Atheros QCA9377) has weak Wi-Fi signal on Ubuntu 18.04.3 LTS

Yesterday I bought Dell’s Inspiron 3538 with preinstalled Ubuntu 18.04.3 LTS.

Everything works pretty much fine (well, there were minor issues as missing a language, a timezone and a region during setup which normally do not miss with vanilla Ubuntu) except Wi-Fi.

For some reason Wi-Fi signal is blatantly weak. First I went to Additional Drivers, there was a wireless device first time I opened Additional Drivers, now it is missing, Ubuntu is not showing it anymore. So I cannot change driver there.

Then I tried installing backports according to this question. I tried few versions, none of them helped. Kernel I am using is 4.15.0-1057-oem.

I really do not know what to do next except installing another kernel (which one?) or just removing preinstalled Ubuntu, download vanilla Ubuntu and install it.

Which is really bad because I bought this Dell explicitly because of its support for Ubuntu and I expected everything to be smooth.

Preventing boot from USB on Dell Inspiron 5559

So what I am looking for is a way to prevent anyone from booting from a USB drive on this specific Dell Inspiron 5559 so normally what I would have to do is to set an Admin password in BIOS that would prevent anyone from booting using a USB drive or change BIOS settings without the Admin password but the bad thing is the admin password could be easily bypassed using certain websites with the System Serial that appear in the message asking for the admin password I won’t post links here but you can search on Youtube and see for yourself so apparently that doesn’t work now I have windows 10 installed and I can use Bitlocker to encrypt my HDD and protect my Info but I am also trying to protect the HDD from sabotage ie formatting the HDD (without using external backup Drive) in short I want that if someone wanted to tamper with the laptop they would need to open the laptop casing and take the HDD out (or even the cmos battery if they tried to reset the BIOS settings) and I am OK with that.

WiFi stops working intermittently on 18.04 (Dell Inspiron 15 5000)

I recently got a new laptop (a Dell Inspiron 15 5000) and have been experiencing stability issues with the wireless connection ever since I installed Ubuntu 18.04. The WiFi will disappear seemingly at random for somewhere between 30 seconds and one minute, then reappear. I have been unable to make it function any quicker by restarting the adapter using ifconfig

The issues are very similar to those described in this askubuntu question. I checked /var/log/syslog as suggested in this bug on Launchpad and did indeed find entries with avahi-daemon[xxx]: Withdrawing address record for xx.xx.xx.xx on interface_name. The suggested solution to disable ipv6 and reboot did not solve the issues.

I am unsure how to properly diagnose the issue and progress from here.

I have tried pinging various addresses while the WiFi is not working, all of which have resulted in the following message: ping: [xxx]: Name or service not known.

Likewise, rfkill list yields the following when the WiFi is not working:

1: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no 

Some system information:

Can’t install ubuntu on dell inspiron 3670 – i5

I just got a brand new desktop a dell inspiron 3670 i5 with a ssd. Im having a real hard time installing ubuntu. Tried making a USB of 18.04lts and that failed on multiple levels to install. I created a 40gb partition in windows 10 disk management but its ntfs or exFAT only no option for ext4. The ubuntu installer isn’t giving me any options for install alongside windows. I have fast boot and secure boot turned off in bios. I am now trying to install from a dvd of 18.04 and i keep getting a message that ubuntu requires atleast 29 gb of free space and this computer has 0 bytes available. For some reason its not seeing the hard drive. Even when i try ubuntu and run gparted it only sees the dvd. Ive spent many frustrating hours on this and need help please!

Installing Ubuntu 16.04 on Dell Inspiron 5482

I am new to Ubuntu and trying to install it on my laptop.
I get through the stages fine until the “installation type” stage where the partition is empty.
I get three buttons, +, -, and change.... When I press the + or change... it terminates the installation and when I press the -, it prompts a message No root file system is defined, please correct this from partition menu.

Do you have an idea what should I do?

Dell Inspiron 7559 GPU issues

I have started installing Ubuntu 18.04 on my Dell Inspiron 7559, but failed to boot. After research, I have found https://connorkuehl.github.io/dell-inspiron-7559-linux-guide/index.html where is described how to install Ubuntu 18.04 and 16.04. Everything went well and now I’m running ubuntu, but only on Intel HD Graphics. Is there a possibility to use Nvidia GPU?

When I’m trying to switch to Nvidia sudo prime-select nvidia, I cannot boot anymore. Boot stalls at “Detect the available GPUs and deal with any system changes” with an “Timeout” error.

My hardware:

Is Ubuntu fully supported on Dell Inspiron 15 3000 series (AMD A9 Dual core)?

My sister has this Dell laptop and is having Windows 10 pre-installed. She is planning to switch to Ubuntu since Windows is making her life very hard.

I just want to check, if this Dell laptop is fully supported by Ubuntu – because, the wifi drivers on Windows has some issues, system is very slow, processor is AMD.

Below are the details of the laptop:

Dell Inspiron 15 3000 APU Dual Core A9 – 3565 laptop

6 GB – 1 TB HDD – Windows 10 Home

Thanks!

Mouse skipping with Ubuntu 18.04 on Dell Inspiron 3558

I am experiencing an intermittent problem of mouse skipping with my Dell Inspiron 3558 running Ubuntu 18.04.2. I sometimes have to reboot a couple of times before it stops skipping. I experience the issue with both wired and wireless mice. I even disabled the touchpad, which helped a little, but the problem persists. Please help.

USB-C port occasionally partially dying on Dell Inspiron 7375

Occasionally while docked with a USB-C dock my laptop’s USB-C mostly dies. All USB devices cut out, but display and power continue working.

The last 1000 or so lines of journalctl are here https://pastebin.com/C1eAwmJZ

All of dmesg https://pastebin.com/aCTRKhg5

I should mention that I’m currently using this solution to get Ubuntu to boot at all, though I’m running 19.04 and it still won’t boot without the parameters. https://askubuntu.com/a/1050026/177527

I’m not sure how to proceed troubleshooting this issue. I’ve had it happen to me on all of 18.04, 18.10, and 19.04 now identically, though now that GNOME finally has good support for fractional scaling I have only this in the way of Ubuntu being my daily driver.
