Sculpt 26.04 Release Candidates

Genode and Sculpt OS
1

Hello everybody,

just now, I published the first alpha image of Sculpt 26.04 under the following URLs. It’s also available via the Sculpt “System → Update” dialog in entry https://depot.genode.org/chelmuth from a running Sculpt installation.

Note, the image represents an alpha state and comes with shortcomings we’re actively working on. For example, the selection of a preset currently deactivates networking, which must be enabled again to download missing depot archives. I will post here when updated candidates were published.

Please report any discovered issues and ask questions on the mailing list or our Discourse forum.

Happy sculpting!

Thanks for making these RC images!

I haven’t had much time to play around with them yet, but people should give them a try - there are some interesting changes in there! Beside the switch to HRD, there are immediately visible changes to Leitzentrale, not to mention fun stuff like USB networking, etc.

I haven’t tried the touchscreen stuff yet, but I’ll report back…

Thanks from me too.
The new usb-net seems to work well on my framework using its lan module. I used it yesterday evening. Today I give my Thinkpad a test drive on the new SculptOS (using wifi and firefox at seol) to write this.

One thing I noticed is that enabling the “usb net” option doesn’t add a button to the “Network” panel - I only see “Disconnected” and “Wifi”. The USB network works (i.e. data is transferred), but the indicator / button isn’t visible.

Is the button / indicator supposed to appear?

I’m glad that this now works for you out-of-the-box :smiling_face:.

Is the button / indicator supposed to appear?

No, that is not yet integrated and for the moment you need to remember that usb_net is used (the way the network is handled will probably change in the future).

Good morning!

Yay, a new Sculpt OS! :smiley:

Just gave a try for the latest build provided here to complement this topic

On my machine:

  • 3 SATA HDDs are visible in the system (this works well) :white_check_mark:
  • The Hard reboot works every time without issues :white_check_mark:
  • The ACPI Hard power down works every time without issues :white_check_mark:
  • The ACPI Standby just hangs the system dead :cross_mark:
    Screen goes black, keyboard disconnects, network stop responding to pings, CPU and HDDs running without any stop, no reaction on hardware power button click..

Btw, is it build with HW or with NOVA kernel? :thinking:

The RC images use NOVA.

I just noticed that “Hard reboot” and “Hard Power down” don’t work on the Framework 16. (These did work in 25.10.) They do still work on the ThinkPad Yoga.

Edit:

It seems to be related to the “ACPI Support” option - it reboots fine without this option.

It also looks like it is intermittent, but here are some lines from the log that might be relevant:
