Review and Usage of Qt5WebEngine
by hamed_khandagh＠yahoo.com 16 May '24

16 May '24

Hi there Genodians. I have thoroughly tested the sample programs provided for testing in the Gems section. Specifically, I have reviewed the "mixer_gui_qt_test" program as a practical example of Qt5. Afterwards, I decided to add a webview to this program for further practice. To achieve this, I needed to use webengine. I manually added the lib.so files to the build directory and also included the resource.tar files in this directory. To extract these files, I used the following command: <config> <vfs> <dir name="dev"> <log/> <inline name="rtc">2018-01-01 00:01</inline> </dir> <dir name="pipe"> <pipe/> </dir> <tar name="qt5_dejavusans.tar"/> <tar name="qt5_libqgenode.tar"/> <tar name="qt5_webengine_qml.tar"/> <tar name="qt5_webengine_resources.tar"/> <tar name="qt5_webengine_translations.tar"/> </vfs> <libc stdout="/dev/log" stderr="/dev/log" pipe="/pipe" rtc="/dev/rtc"/> </config> However, after building the program and executing it, I encountered the following error when using the QWebEngineView class functions: [init -> webview_test] Error: no plugin found for read(-1) Your assistance in resolving this issue would be greatly appreciated. Thank you for your attention to this matter. Warm regards, Hamed

It is good to be back. I'm experimenting with building and running Sculpt OS, but I cannot get networking to function when running it on my Linux machine. I would love some help!

Hi there Genodians. It has been many years since I've built and experimented with Genode, and now seems like a perfect time to get back into the picture. Right now, I want to prototype and experiment with running Sculpt OS directly on my current Debian 12 installation, in an Ubuntu 22.04 LTS podman/distrobox container. I'm using the current master branch of Genode from GitHub. It took me a bit of time to reread the documentation and a handful of very helpful Genodians.org articles, and I was able to build and run the sculpt_test run script after some configuration and switching my Linux environment from Wayland to Xorg (fb_sdl fails to initialize on Wayland). It all works perfectly with the exception of networking! I'm very happy with this progress and it was more than I expected to accomplish with my first revisit of Genode. I am building and running Sculpt OS using the following command in my Ubuntu container: "make -C build/x86_64 run/sculpt_test KERNEL=linux BOARD=linux LOG=core" When I click the Network button at the top-right of the leitzentrale, it only displays two buttons - "Off" and "Disconnected". Clicking on Disconnected initializes nic_router, but I still have no internet access. Feel free to throw me any ideas or troubleshooting tips. I'm having a lot of fun but having working internet will be amazing. Joel

Edit ram allocation to processes in Sculpt OS?
by Jack Curran 07 May '24

07 May '24

Hello, I've started using Sculpt OS and the integrated Falkon web browser. It frequently crashes when I have several tabs open, I believe this is because the ram it has been assigned is too small. I couldn't seem to find any mention of how to edit the ram allocated to processes in the Sculpt OS documentation? How do I dynamically edit the allocated ram to processes such as the Falkon web browser? When I am using the Leitzentrale and I click on the Falkon web browser, I can see it shows 1.95 GiB / 2.00 GiB, I am guessing this is the allocated ram? However I am only assuming this is the allocated Ram size as it does not specify what type of storage this is, i.e Hard Drive Storage or Ram Memory. The audio works in the browser too, I was able to play music in youtube music. However, the first couple times I tried playing any audio through Falkon, it didn’t work. I rebooted and started fresh RAM FS in an attempt to get audio working. For the first 2 or 3 times it didn’t work. I am not sure what I did differently, but on the 3rd time I tried and downloaded the Falkon browser, the audio suddenly worked. I was able to control the volume by editing the config audio XML file and saving it. I will need to do more tests to see if the audio not working was a fluke or I was doing something incorrectly before. Thank you, Jack Curran

Sculpt OS stuck on boot logo - 13th Gen Intel Core i7-13700HX - HP ZBook Fury 16 G10
by genode＠axioms.info 07 May '24

Hello, I'm using a HP ZBook Fury 16 G10 Mobile Workstation PC with 13th Gen Intel Core i7-13700HX, however Sculpt OS won't boot on it. It gets stuck at the boot logo screen. I can boot it using the same USB on my Sony Vaio Intel Laptop - Intel Core i7 Q 740. Therefore the USB image is valid. I'm not sure what else to try as I have followed the guide for running Sculpt OS on hardware and I changed all the Bios settings I could. The only one I can't find access to is the Data Execution Protection option in the bios, it doesn't seem to exist as an option to enable or disable in my bios. But the rest of the options I was able to enable such as virtualisation VTX, VTD, Disabling secure boot etc. I can UEFI boot Windows and several Linux distributions on the computer with and without TPM or Secure boot enabled. Any help is appreciated. Thanks.

Seoul vs. VirtualBox
by John J. Karcher 01 May '24

01 May '24

Hello Genodians, During the Roadmap discussion, Alexander expressed some relief about switching from VirtualBox to Seoul for his main VM. I can't find much information about Seoul online, though. Is there any handy info about: 1. Advantages / disadvantages of Seoul vs. VirtualBox 2. What's involved in migrating from VirtualBox to Seoul? 3. Maintaining a Seoul system (tools, etc.) Thanks! -- John J. Karcher devuser(a)alternateapproach.com
