How do I verify the latest Dell A10 BIOS is installed?

Dell released the A10 BIOS 19 May 2008 and updated it 21 June 2013.

From Terminal:

user@latitude-d620:~$   sudo dmidecode -s bios-version A10 user@latitude-d620:~$   sudo dmidecode -s bios-release-date 05/16/2008 

This date does not match Dell’s. man dmidecode does state, “[Because it does not] probe for the actual hardware[,] the presented information [is] possibly unreliable.” Is this an example of unreliableness? Does this date indicate when the BIOS was last updated, demonstrating mine is outdated? or only the release date itself, implying nothing about when mine was last updated?

How do I determine whether my “A10” is the 2013 updated version?

How to keep track of the installed software/system configuration to restore after a fresh linux install?

I have been thinking of writing some sort of utility for linux that keeps track of all my installed software and configuration. Something that after doing a fresh install I can just run it and will restore my copy of ubuntu as it used to be before doing the fresh install.

I do not know exactly where to start with this. I know that you can get a list of user installed software from dpkg -i | grep ii.

I would really appreciate any suggestions.

Unable to run (installed) Hubstaff

I am using Kubuntu 18.04 and I want to use Hubstaff, which was successfully installed according to its interface, but in the terminal it showed terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid . The same message appears when I go ./HubstaffClient.bin.x86_64. And here is the full message:

List of pages where app is installed? Hopefully via PowerShell

Scenario: I am migrating a bunch of apps to the cloud and I’m trying to justify if they are being used before I rewrite them (they are oooooold). We are in SP2013 on-prem currently,

Problem: I need to know what pages the Apps have been placed on. I was able to get a report of the sites that the App is installed on, but that doesn’t actually give me usage, since the app can be added to the site, but not be placed on a page.

My ask: Can anyone give me a PowerShell script that will pull pages the custom apps are installed on? I have both Googled and explicitly searched on Stack, but am either using the wrong phrasing or it can’t be done. Your assistance in advance is greatly appreciated.

Just installed drupal-7.65 and getting JIT compilation error

Brand new to drupal and website building in general, just set up a local server and installed drupal 7.65. Before doing anything, I am getting a long list of errors whenever I navigate to a new page, each starting with the following:

Warning: preg_match(): JIT compilation failed: no more memory in *

Along with this error: Your PHP max upload size is bigger than your max post size. This is known to cause issues in some installations.

Seems like something I should fix? Anyone know how?

Ubuntu 18.04 installed (dual boot) but not working on Dell XPS 9570 : SATA problem?

I’ve just installed Ubuntu on a Dell XPS 9570 but now can’t access it after rebooting.

In the first place, the installation program couldn’t detect any hard drive so I changed the SATA parameter (previously on RAID) to AHCI. This solved the detection problem, I installed Ubuntu and it seemed to work fine.

The problem is that after rebooting, Windows 10 wouldn’t load : I changed the SATA parameter back to RAID and now Windows works fine.

But now, if I reboot to get back to Ubuntu, I get the following screen : ACPI Exception / ACPI Error / CPU temperature above threshold How can I access Ubuntu, while still having access to Windows ?

Best, Lucas

HDMI port not detected on Ubuntu 18.04 (with bumblebee installed)

After going through all related questions (dozens of them), I still couldn’t figure out.

system & hardware spec:

Lenovo Thinkpad P51, NVIDIA Quadro M2200 and Integrated Intel Graphic (hybrid graphic card),

Ubuntu 18.04 (dual boot with Win10)

symptom: When connected external monitor with HDMI port, no monitor detected.

  • xrandr outputs:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm    1920x1080     60.02*+  60.01    59.97    59.96    59.93    48.00      1680x1050     59.95    59.88    
  • lspci |grep HDMI outputs nothing, lspci |grep VGA gives the following:
00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04) 
  • prime-select query gives intel (used to be nvidia, but when installing bumblebee and avoid the infamous login loop, I switched to Intel.
  • Nvidia Driver: nvidia-driver-410 with packages like nvidia-410 installed.

additional note: This worked before and still work on Win10 (dual boot), thus shouldn’t be a hardware problem, but rather a config or hardware config one in the Ubuntu 18.04 system.


The website program is installed under the local wampserver, but the access path still jumps to the domain name

I downloaded the magento 2 website program and database for local debugging of the local computer wampserver. I have installed the website program and database, but I now enter the path: localhost/supwatch/

The website can be opened, but jumping to the domain name of my website is not a local path! How to solve it? enter image description here
