how to automatically turn off gnome extension when I connect the external monitor (RGB)

So I am using “hide top bar” extension for gnome, but whenever I connect an external monitor (and the screen is located “above”) the laptop screen I can’t move my cursor to that external screen because of the top bar pop-ups instead.

So I am turning it off and on manually whenever I connect an external monitor. Is there a way to automate this?

Can any ally benefit from the help action during a combat turn? [duplicate]

This question already has an answer here:

  • Can the Help action be used to give advantage to a specific ally's attack (rather than just the next ally who attacks the target)? 2 answers
  • Do I choose the target or the ally for the Help action? 2 answers

Party members Alex, Bart, and Caroline are in combat with a Drow, in that turn order (A, B, C, D).

Alex uses the help action on the Drow, being within 5ft. If Bart chooses not to attack on her turn, can Caroline attack with advantage because of Help? If Bart decided to attack, would Bart have gotten advantage instead?

Does a specific ally need to be named to benefit from the advantage? Or is it first-to-attack?

What happens when two creatures actually share the same turn?

Related to this Q/A (“Does a controlled mount share its rider’s turn?”) where there doesn’t seem to be a consensus on whether or not the rider and their mount actually share a turn.
I am left wondering what even happens when things do share a turn:

The true polymorph spell states:

Object into Creature. You can turn an object into any kind of creature, as long as the creature’s size is no larger than the object’s size and the creature’s challenge rating is 9 or lower. The creature is friendly to you and your companions. It acts on each of your turns. You decide what action it takes and how it moves. The GM has the creature’s statistics and resolves all of its actions and movement.

Similarly the simulacrum spell states:

The simulacrum is friendly to you and creatures you designate. It obeys your spoken commands, moving and acting in accordance with your wishes and acting on your turn in combat.

It is notable that these do not simply say that you have the same initiative they say that you have the same turn.

Does this mean that you and the creature/simulacrum can go back-and-forth taking actions and moving throughout your shared turn?

How to turn off Nvidia GPU on a headless server?

I am running a headless server with an Nvidia GPU. Even when the GPU is not doing any work, it is consuming about 25 Watts of power:

Is there a way to completely turn off power delivery to the GPU when it is not in use?

I tried sudo prime-select intel Which does cause nvidia-smi to stop working, but a power meter connect to the wall shows exactly the same power consumption with either intel or nvidia selected.

Completely removing the GPU reduces the power consumption by about 30 Watts as expected.

The main purpose is to save power and costs during idle operations, with an option to spin up the GPU when it is needed (remotely via ssh).

Can a College of Swords bard use Blade Flourish multiple times in a turn?

Bards of the College of Swords have a feature called Blade Flourish that lets them use their Bardic Inspiration to add a modifier to their Attack action:

Whenever you take the Attack action on your turn, your walking speed increases by 10 feet until the end of the turn, and if a weapon attack that you make as part of this action hits a creature, you can use one of the following Blade Flourish options of your choice.

The feature then goes on to read:

You can use only one Blade Flourish option per turn.

Does this last clause mean that you can only use the feature to affect one attack in that turn, or that you can only use one of the three options for any attack you wish to affect during that turn?

For example: Could I hit my first attack and choose to use Mobile Flourish, and then hit a second attack in the same turn and expend a second usage of Bardic Inspiration to use Mobile Flourish again?

How to understand set notation and turn it into regex?

{w | w ∈ {a,b,c}*}

What does the above notation mean and how to turn it into regex?

my understanding is that this set notation will produce {abc, aabbcc, cab, bba} basically any number of a’s b’s and c’s in no particular order so the regex would look something like (a|b|c)* is this correct?

{w | w ∈ {b}* U {c}} and something like this means I have a language that contains any number of b’s or just a c {b, bbb, bb, bbbb, c} in regex b* | c is this correct?

Dealing with people who turn up late for sessions

I run sessions every Monday evening at a pub in the centre of London, and most people come to play straight from work. Up until recently we were attempting to start at 7pm, but there were one or two players out of five who struggled to get there on time, which was causing disruption to the rest of the group.

We talked about this as a group and decided to move the start time back to 7.15pm, with people asked to arrive early enough so that we could start playing at that time. However, what has actually happened is that some people are now arriving at 7.25, which means that overall we are losing a good half an hour of gaming time before everyone is sat down, knows what is going on and are ready to play.

I find this extremely frustrating and disrepectful to me as GM and to those players who make an effort to arrive on time. The problem is that I’m not sure what, if anything, I can do to stop this from happening. I’ve considered various approaches, with the most severe being asking disruptive players to leave the game, but I really don’t want to have to do this.

So, my question is:

What strategies are there for minimising the disruption caused by players that turn up late to sessions, and what can I do to prevent this from happening in the first place?
