USB Device over current status detected [ASUS motherboard]

Submitted by Druss on Mon, 2020-10-05 21:53

An ASUS ROGSTRIX B450-F gaming motherboard that I have had been working perfectly fine for a year. Suddenly though, booting up the system resulted in the following message on the POST boot screen:

USB Device over current status detected !! System will shut down after 15 seconds

The system would shutdown and restarting would result in the same message. I couldn't get into the BIOS either as the del and F2 keys did nothing.

Installing a legacy pear package in Xubuntu 20.04

Submitted by Druss on Sat, 2020-09-26 20:03

Trying to install a legacy pear package on a new version of Ubuntu is a bit of a chore as things are broken. For starters, using

$> sudo apt install php-pear

$> sudo pear install foo

results in errors such as

Notice: Trying to access array offset on value of type bool in PEAR/REST.php on line 187

and

Freeplane hangs in Kubuntu 18.04

Submitted by Druss on Mon, 2019-03-11 17:58

Freeplane, a fork of the mind-mapping program, Freemind, works really well. Except for the fact that in my (K)Ubuntu installation, it sometimes hangs in the middle of editing a node. Once it becomes non-responsive, the only fix is to kill the process and restart the program. The version of Freeplane in Ubuntu 18.04 is 1.6.13. However, the current version (March 2019) of Freeplane is 1.7.7. So, it's highly possible that upgrading Freeplane to the latest version will fix this issue.

Create a bootable Windows installation USB drive using Linux

Submitted by Druss on Sat, 2019-01-19 02:32

I needed to install Windows and downloaded the 4.7GB Windows 10 ISO from Microsoft's website. Since I only had Linux machines at my disposal (and no DVD drives), I had to look to install the ISO on a pen drive. While the purists advocated that I use dd to accomplish this, I found that getting the USB to be bootable was something of a chore. So I looked for a friendlier solution and this is what I found for Kubuntu:

Netflix Playback Error Code: F7701-1003

Submitted by Druss on Sat, 2018-11-24 01:56

So I tried playing a video on Netflix in Firefox and while everything worked including the previews while hovering over a title, the actual movie/TV episode failed to play and resulted in the following error:

Playback Error Code: F7701-1003

The main thing that needs to be done is to enabled DRM support in Firefox's preferences section. (Look for a checkbox titled "Play DRM-controlled content".)

Hearthstone: Unable to claim gift via the battle.net client on Linux (PlayonLinux)

Submitted by Druss on Thu, 2018-01-11 01:27

So, Blizzard is offering a gift to players for some reason (possibly for a bug, I forget). But on my Linux install (via Playonlinux), clicking the Gifts button at the top just brings up a blank screen. You are supposedly also able to claim the gift by logging onto battle.net in a browser. But where does one go from there? There's a "Gift history" option in your account settings section, but that does not list anything that is claimable.

Kubuntu/Pulseaudio: Record both mic and system audio

Submitted by Druss on Fri, 2016-10-14 19:35

Today, I started dabbling in doing some screen recording in Linux and while I could find programs to record the screen, I couldn't get the audio working as I wanted. By default, the programs record either the system audio, or the mic audio (or if the program is shit, neither); they don't record both the system audio and the mic audio. The fix for this on my Kubuntu 16.04 (Xenial) system which uses the Pulseaudio system to manage audio is as follows:

Enabling logging for your MySQL queries from the MySQL prompt

Submitted by Druss on Sat, 2016-06-04 01:44

I usually find it a chore to edit the MySQL conf files (as for one, I often have no idea which my.cnf file to edit!) One way to work around this issue, particularly if you want to change a setting temporarily, is to simply enable the change dynamically via the MySQL command prompt. This can be accomplished by modifying "global" variables which can be listed with commands like so:
