Navigating in the mini timeline is very CPU intense

Installation & Configuration Linux
#1

When navigating in the mini timeline in Ardour 9, my CPU usage goes to round 12 % and the CPU temperature rises from 40°C to 74°C. This is not the case when using the scroll wheel, so it doesn’ t seem to be a problem with the navigation in general. Maybe a wayland issue?

Quite possibly. The official statement is that Ardour on [X]Wayland is not supported.

oh, ok. Wasn’t aware of this. Then I have to wait another 5 years :smiley:

#4

Always the optimist :slight_smile:

I can’t fathom why people would depend on a new, incomplete and relatively unproven windowing and compositing system on their Studio workstation, it’s kind of an essential base-level thing to be able to rely on… :thinking: Red Hat seems to like making all of Linuxdom their beta-testers (if early PipeWire and Wayland are any indication) :roll_eyes:

My good vibes are all aimed at XLibre, hoping they can achieve the impossible and make X11 so good that it’s a viable alternative for Wayland for many years to come… :crossed_fingers:

I have a new PC Ryzen 9700X with iGPU and had a lot of graphic issues with X. Wayland works flawlessly instead :wink: .

Maybe Studio One is for you!

Wiki says that “Initial release 30 September 2008; 17 years ago”, so it’s not like Wayland was released as a Christmas gift last year.
Lots and lots of programs work just fine under Wayland.

The fact that Ardour depends on the ancient Xorg is a bit sad, though quite understandable given the number of developers.

XLibre appears to have some quite severe moral and technical quality issues so it’s unclear if one really wants to rely on them going forward.

I’m surprised it managed to live that long :slight_smile:

Also keep in mind that there are currently no plugin standards that support Wayland.

I expect those are mostly single Window based ones. While Ardour is in the same boat as e.g. KiCad and Wayland Support | KiCad

I don’t see X11 going away anytime soon, ideally XWayland would get some attention, other than that XNest is perhaps the option that sucks least.

Wayland’s design omits basic functionality that desktop applications for X11, Windows and macOS have relied on for decades…

Sure, it has it’s work cut out for it and ‘corporate Linux’ wants it to fail for sure… As far as morality give me a break, Canonical and Red Hat are beacons of morality!?.. if you read the XLibre development statement in it’s entirety they welcome all comers to contribute, their contributions are going to evaluated on their coding skills above all else, if that’s immoral then I guess we’ll have to agree to disagree…
