Q: Disable haptic feedback on Apple trackpad

I have just installed Ubuntu on my 2015 MacBook Pro. The haptic feedback (the noise made by vibration when clicking) was optional in MacOS, but I don't see a way to disable it in Linux. How can I do this?

Terrance

I just got serial downvoted. Thing is, I know who it was by. askubuntu.com/users/565196/kong

Q: for Linux in the enterprise, what percentage of the market is RHEL/CentOS/Oracle?

I worked at Hortonworks in a previous life. The vast majority of our customers ran RHEL or some Linux variant that's similar to RHEL (e.g. CentOS, Oracle linux, etc...). I don't have an exact number, but it felt like 80% to 90% of the companies I interacted with had settled on RHEL/CentOS/Oracle ...

debian ubuntu centos rhel

Videonauth

@Terrance well next midnight UTC it gets reversed anyways

Terrance

@Videonauth Ah, thank you!

Videonauth

already 3 DV/UV in succesion from the same user trigger the script

Terrance

That is good to know.

Videonauth

3:33 AM

even two if it is in short succesion

Terrance

Had a little discussion with the person and they got mad at me because I asked them not to cross post.

Next thing I know, lots of downvotes.

Videonauth

hehehe sounds familiar, well monitor it and keep it in mind, if they not got reversed you should let one of our mods know

Terrance

Sounds good to me! Thank you! =)

Videonauth

this script is in place since the eklat in 2016 where many people got rep removed

Terrance

I remember that happening to me.

I think I lost about 1,000 on that one

Videonauth

3:36 AM

yeah i lost some points too on that day

since then there is a script running every midnight

dunno how fast you got those dvs but if they are fast enough they should trigger

how much did he dv you, if i may ask?

Terrance

WOW, that OP opened another new question instead of editing the original, again. askubuntu.com/questions/1076472/… and askubuntu.com/questions/1076481/… and askubuntu.com/questions/1076395/…

Just 16 points today or 8 of my answers all right in a row

Videonauth

ah ok thats far enough to trigger the script for sure lol

Terrance

Is that script instant?

Videonauth

@Terrance that script goes over the DB once a day

Terrance

Ah, OK

Videonauth

3:41 AM

always 0:00 UTC

midnight

i never will remember if this is am or pm lol

Terrance

Well, we are past that, since it is 3:41 UTC, if my watch is correct. =)

LOL

Videonauth

and on top of that im using 24 hr format

as im used to it

Terrance

Ah

I am now too used to it. I prefer it. Less confusing. =)

Videonauth

so theres only one 0:00 per day

indeed

Terrance

Indeed! =)

Videonauth

3:44 AM

well don't worry if this was in a short timeframe, but i dont get why he has three questions, from their title they look different

ah ok now i get it its all about cuda

Terrance

Yep!

But he denied that.

Videonauth

well if he needs to ask about installing cuda hes probably not firm enough to use it anyways ;)

Terrance

I think so

=)

Videonauth

this is a buzz word like kali

Terrance

LOL! I can see that.

Videonauth

3:46 AM

if youre in the league which can properly use kali you not need to ask questions

Terrance

Exactly!

Videonauth

or really if, you have enough knowledge to fill your question with valuable information beforehand

Terrance

I so agree with that! =)

Videonauth

so he has a local repo for cuda?

and he has it double on his system

and i only looked on that apt update output of him

and he seems to have missed to register the keys for some of the repos and on top of it one repo is so often in that list that it hurts

Terrance

Well, those instructions on those sites are horrible. In the original question I pointed to an answer I wrote that does one repo / PPA and installs everything needed. I come back this evening and he has gone off on his own and his system is having PPA issues

Videonauth

3:51 AM

well thats his lesson to learn :)

Terrance

Probably missed the keys as well, but installing CUDA from the developers site like that can mess your system up. I learned the hard way before. =)

I am feeling that way now.

Videonauth

true, well i install twice a year fechly

by hand using debootstrap

Terrance

Ah, I haven't used that yet.

Videonauth

and doing this way even an uefi installation

if you know how this is as quick as using the installer, but you only get what you really want this way

Terrance

I see. I only have an Apple MacBook that is remotely close to UEFI, but I don't use it for anything else. So, UEFI questions here I am no good at. =)

Videonauth

3:54 AM

the process is much like setting up arch

Terrance

Ah, that makes sense.

Videonauth

even described it on my blog but its actually a bit outdated, didn't have the passion yet to rewrite it

Terrance

It's all good! =)

Videonauth

videonauth.ddns.net

only one thing left for me to figure out, how to create a bootable device which can support both legacy and uefi

Terrance

Cool! And that is a good question to cover about dual legacy and UEFI. I say go for it. =)

Videonauth

4:03 AM

he's probably sticking with cuda 8 because most tuorials are made for 8

Terrance

Probably, I could see that

Videonauth

im searching like mad for a tutorial for pycuda

Terrance

Of course, it is those old tutorials that messed up my system

Videonauth

lol

as always :)

i really have to rewrite my debootstrap tutorial

Terrance

I am going to look into that. But not tonight for me. I am starting to get tired. I had to switch over to my reader glasses to work on the computer since the screen is starting to get blurry. =)

Look into debootstrap that is.

Videonauth

4:13 AM

ah no rush, its a sience for itself

took me almost 2 years to master it

the autodidactic way that is

and lots of killed VM's

Terrance

Well, that is definitely one way to learn. =)

Videonauth

gnah python-pycuda and python3-pycuda does not like the 396 nvidia driver -.-

Terrance

That's no good!

Videonauth

well easy fix on the hand lol

i hack the deb files dependency

Terrance

That's good.

I need to install and check it out.

Videonauth

4:15 AM

libnvidia-compute-396 :D veersion 9.1.85

Terrance

Yep

Videonauth

thats in the package archives for 18.04

Terrance

I bet in 16.04 it is probably fine

But I am not going to reinstall on this system again

Well, right now that is..

Videonauth

ah no the 390 driver is what the pycuda package wants

Terrance

Ah

I am running the 396 driver

I could roll back for now.

Videonauth

4:17 AM

but im on the brant sparking new 396 driver

its simple apt download the deb files, unpack them, edit the dependecys and then install with gdebi :P

and if there comes an update, you get it from the archives and then its probably fixed

Terrance

I need to mess around more. I always forget things like that, especially when it has been a long time since the last time I did something like that.

Videonauth

if not roll back to the deb files you hacked and then apt-mark hold it

you no want to know how many ubuntu installations i killed in the past three years :D

i know it meanwhile inside out

still suck at bash tho :D

Terrance

But then again, I have noticed that NVIDIA has not updated to support 18.04 yet. developer.download.nvidia.com/compute/cuda/repos

You have probably killed way more than I have. =)

Videonauth

its in the low 3 digit numbers

Terrance

WOW

Videonauth

4:22 AM

150 - 200 or so

Terrance

More than me

Videonauth

mostly VM installs

Terrance

But then again, I have probably setup more Ubuntu servers and stuff, considering my job deals with that. =)

Videonauth

testing things before applying them on my main machine

Terrance

Always a good rule to follow. =)

Videonauth

4:23 AM

server side i still learning

true if you screw up a VM you set it up new or roll back to a snapshot

if you screw up your main machine you not even can chet the internetz for solutions

Terrance

True!

Videonauth

good morning you tasty treat :P

Terrance

I am lucky since at my job, most of it right now is dealing more with cloud servers, so messing up one during install and stuff normally doesn't affect things. After it is added to the pool, then that is where it gets dicey.

Videonauth

yeah cloud is another thing i have not dabbled with

setting up an apache ok, this i can, using vhosts and multiple domains on one ip, nope never did that either

Terrance

It gets quite fun!

Videonauth

4:27 AM

well im eyeing at nextcloud 14 right now

but i guess my small raspi 3b+ is not well suited for that endeavor

Terrance

I actually have not dived into my own cloud yet.

Only ones with my job.

Videonauth

ah ok

well i do not trust coulds and storage if i not host it myself ;)

Terrance

That is a good mistrust to have.

:)

Videonauth

in regards to private data I'm a bit paranoid

Terrance

Nothing wrong with that. =)

Videonauth

4:31 AM

my offsite backup which i do once a month is made of HDD's laying in a bank-locker :P

Terrance

That's good! When I worked at the game studio, that is how we did ours. They were taken offsite in locked safes and then stored in several locations so we didn't have one point of failure. It was effective, but too bad that company didn't last. :(

Videonauth

wel the market is a shark tank sadly

either you have one or two really good IP's or your going down thanks to EA and co.

Terrance

Yeah, that company folded back in 2008, but the owner of it ripped off all us employees to the tune of over $2 million and owed over $2 million in taxes as well. And now we won't get a thing.

The guy that sits behind me at work now used to work at EA.

Videonauth

thats sick shit

Terrance

I know several people from there and they hated it.

Videonauth

4:35 AM

well Ea killed more game studios than any other on the market right now

Terrance

Sounds about right

Videonauth

and good studios tho

bioware is half dismantled at the moment

Terrance

Yeah there were good ones out there. The one I worked at was actually really good until they folded.

Videonauth

EA pulled the plug on their best IP

mass effect

Terrance

Sucks!

Made me sad when that happened!

Videonauth

4:36 AM

and the game failed the last amrket release only dur to the time pressure EA has put on the studio

makes me sad too, im a gamer at heart

Terrance

Of course, working at a game studio is not what it is cracked up to be.

Here are a lot of games that I helped with: google.com/…

Videonauth

well the timeframes are too hard to really create new stuff or you need teams in the hundredts

Terrance

UGH! That list is missing the Tale of Desperaux

Videonauth

NFS most wanted rings a bell

an IP now owned by EA ...

Terrance

Yep

Videonauth

4:40 AM

i hope feral soon transfers shadow of the tomb raider to linux

this will be the next game i cash out money for if

Terrance

Oh no, that game is there, I see it. That was a failure due to Brash Entertainment that folded around the crash of 2008 and the game went to Sony without a dime being sent back to the developers. So, Sony sold it, and we made absolutely nothing on it. Grrrr :(

Videonauth

sony is another bloodsucker in the media biz

Terrance

Tomb Raider would be cool!

Videonauth

one of many companys i really dislike

well the last two tomb raider are available on linux

the third part of this trilogy is just been released on windows, xbox, and playstation

Terrance

Sony indeed is! But due to the folding of Brash, that is who they had the contract with, so once it was folded, we had nothing to stand on. The company I worked for folded soon after.

Videonauth

4:42 AM

but i'll wait for feral making a port which will surely happen

Terrance

Cool! I don't mind waiting for ports for Linux.

=)

One of my favorite games in Linux right now is Cities: Skylines.

Videonauth

facebook.com/profile.php?id=1560834074008271&ref=br_rs

@Terrance yep but checking the workshop on cities skylines is addictive lol

Terrance

Indeed! =)

Videonauth

when i now load my cities installation it takes 24 GB ram and about 60 GB swap

chuckles

Terrance

WOW!

That is insane!

Videonauth

4:45 AM

btw. fun fact, if you try this on windows the game simply crashes :D

not on linux

Terrance

I bet!

Videonauth

you won already, i know because i had it before running on windows

before my switch to linux

Terrance

=)

Videonauth

there are only two games i really mis from my windows time

witcher III and space engineers

Terrance

Ah, never played them.

Mine are SimCity 2000 and Flight Sim 95

OK, I need to head to bed! My eyes are not focusing any more. Have a great time! =)

what a lot of images :P

vtc'd

David Foerster

@Rinzwind Thanks. I already asked OP to use text instead of images but they say "pc gets mad" when they try and ultimately the images don't hold much relevant content beyond the fact that Ubuntu detects the storage devices.

If the text content was more important I would have pressed the issue already but I decided against it.

@Rinzwind More like she gives him the boot if he doesn’t. ;-D Choleric outbreaks are rarely confined to specific environments.

More reasonably I believe friends, co-workers or other trustees convinced him that there’s a problem years ago and to now seek counselling since he can’t hold his temper even after he was made aware of it.
