Thanks a lot. I googled that some time ago, but couldn’t find anything (except severe warnings concerning the security which in this case I also find kind of exaggerated).

#311

The only truly secure computer is one that’s never turned on.

Point is its a balance between practical and secure. The great thing about Linux is that I get to make those decisions…

Unless you’re running into some measured problems with your latency, the stock kernel is most likely going to work great. Enabling high resolution timers, preemptible kernel, and enabling JACK to use real-time scheduling is likely all you’ll need!

This is a little bit specific and unrelated to music, but I wondered whether anyone had ever had the error failed to write reg 1a6f4 wait reg 1a706 or similar (and if they managed to fix it)?

#314

When does this happen and where does the text appear? Did you ask google?

#315

It happens at start-up and shutdown, I can post dmesg logs if that may help. The issue is that it greatly slows down start-up and shutdown and also slows down opening programs. I have Duckduckgo’d and even Googled the error and didn’t find anything relevant, but I gleaned that it may be an AMD integrated graphics issue. Thanks for giving me a hand!
Edit: just posted a $10 bounty on elementary OS’ Bountysource page — I’ll see if that helps things along…

thank you, so cool
enjoying the process

I was just exploring Yoshimi, it’s a pretty neat synth for linux.
I recommend giving it a try if you haven’t already.

return of the perennial gripe: why in the world are trackpads in linux so completely terrible? can someone working at apple please please contribute a new linux driver?

wrote a several page rant and erased it, but checking if anyone else is equally enthused and has found a solution.

Same for power management.

My conspiracy brain says the poor performance is because Apple sits on so many patents for track pad tech no one else can come close.

ugh, this is the major reason why i haven’t switched to a think pad + linux for my full time personal laptop. you basically have to use a mouse if you need to do anything at all accurate (for instance audio editing).

to me the problem is more than accuracy. when a tool is clunky it is hugely distracting. ie, i spend time trying to fix the tool instead of using the tool.

which of course is why my career is basically making tools now.

please kill me before i start making trackpads. :slight_smile:

What are you missing/what’s annoying/what doesn’t work?
And which trackpad + which driver are you using?

#323

Because linux is primarily developed for secure data servers and ideal for jobs across cluster nodes in the sciences, not personal computing.

In the past 15 years, these sorts of issues have barely gotten any better, while everything else has improved. I mean the fonts in linux still look like crap.

Bitwig and u-he are a godsend, like an oasis in a desert.

thinkpad x1 carbon. i believe elementary uses synaptics.

main issues:

  • acceleration is off. “sensitivity” is just a one dimensional config option. basically my assumption is that the accel/denoise/sensitivity algo in the driver is simply bad in that it does not produce repeatable results. i consider myself to be very physically capable with tiny movements, and the trackpad straight up makes me feel like an infant because i can’t exactly predict where the pointer will end up.
  • two finger scroll has a perhaps 500ms delay before it starts, and then the scrolling is chunky, but with a sort of easing in/out, giving the illusion that it’s smooth/precise. again this is an issue of not knowing what’s going to happen when you do an action, and so you fight the tool when it fails expectations.
  • this is minor, but the screen refresh of the pointer is simply not as fast, which gives a sense of fragility.

i’ll dig into the driver later… some of this might be remedied. but the fact that these are the defaults speaks to the priorities.

Yoshimi is my most-used Linux synth by a pretty wide margin.

After a couple seconds on Google, I think Elementary uses libinput.


Article claims to make the libinput touchpad behavior ‘more like mac os’. Good luck!

One relatively simple thing you could try is switching to libinput which is the current/new/modern touchpad driver. It’s supposed to give a much better out of the box experience than the old synaptics driver. Tbh I am/would be surprised Elementary doesn’t use libinput by default.

Anyway, I haven’t used libinput recently because it doesn’t support kinetic scrolling (or actually it defers that responsibility to the applications/toolkits) which I didn’t want to live without. But I noticed Firefox, which is the main reason I want it for, now supports kinetic scrolling, so I might give it a try again.

The synaptics driver is pretty much abandoned, but does support kinetic scrolling out of the box. It does kinetically scroll everything though, you might or might not enjoy seeing all your windows wizz by like a slot machine for example :stuck_out_tongue:
The default settings I didn’t really like, this is what I ended up with:

$ cat /etc/X11/xorg.conf.d/75-synaptics.conf 
Section "InputClass"
  Identifier "touchpad border config"
  MatchIsTouchpad "on"
  Driver "synaptics"
  Option "TapButton1" "1"
  Option "TapButton2" "3"
  Option "PalmDetect" "1"
  Option "MinSpeed" "0.5"
  Option "MaxSpeed" "2"
  Option "AccelFactor" "0.01"
  Option "VertScrollDelta" "-300"
  Option "HorizTwoFingerScroll" "1"
  Option "HorizScrollDelta" "-300"
EndSection

All the available options can be found using man synaptics and there’s a rather complete page on the Arch wiki about it as well.

tldr; It might suck a bit out of the box but at least you can tweak it :wink:

If you have the arsenal to fight Apple with their haptic trackpad tech I’m SUPER HYPE for that.

/me types this on a macbook pro with a giant trackpad that doesn’t have any springs in it.

but I feel the springs in my fingers

I’d used ZynAddSubFX on occasion before, but not Yoshimi until now - some of the sequencer presets are rather nice, especially though a whole bunch of canyon echo… time to explore more.
