Operating Systems and Porting / Re: [NEWS] Fedora 42 Beta

However it is not fair to say its UX is the most pleasant to use.

It depends on habits. For me, at one time it was very convenient. I am not a proponent of implementing by force a UI that is good for a phone on a desktop computer, which the Gnome team is persistently pushing on us.

A consistent UI is what had BeOS 30 years ago, now Haiku.  All written in C++ and completely unrelated to X11. Strangely, no one came up with the idea of porting that ready-made UI to Linux, they just messed around with Gnome and KDE. On Wayland the most suitable for me is Hyprland, unfortunately it is still far from full functionality.

At my place Wayland works strangely, and in fact a whole bunch of applications have problems with it, and I don't have the strength to inquire whether it's just the protocol or not. To me, it's just an incomplete product, which instead of bridging the divide between different DEs only exacerbates it by blaming the lack of support for a certain element on some DE or library. The result is that applications written for one DE will not work well on another. Applications with the latest Gtk are already a complete departure, they operate according to the principle of if you're with us it's ok if you're with us and if you're not it's off.

I, unfortunately, said goodbye to the Fedora distribution... I still need X11 and that will not change for a long time. Gnome is getting more and more frustrating from version to version. I went back to simplicity, FreeBSD 14.2 + X11 + Enlightenment 0.27 ;-)

I am using 15.0 in qemu. Works fine.

I have the same problem on Fedora 39 on Talos. Restarting doesn't work. You have to turn the machine off and on. I got used to it

My Talos II, Fedora 39:

Code: [Select]

Architecture:             ppc64le
  Byte Order:             Little Endian
CPU(s):                   72
...
  Socket(s):              1


Could it be a Talos II Lite?

No, it's a full Talos II but with one CPU. When I feel that the hardware is already inefficient I will buy a second CPU

So far the only program that is too slow on Talos is Firefox

Is fast reboot on or off?

I have "Auto boot -> Disabled" in the Petitboot configuration, but I haven't changed that since I started using Talos.
I guess it shouldn't make a difference since rebooting worked fine on older kernels?

What worries me most is the very large variance in SSD performance from version to version. Once it is 4.5 GB/s and the next time it can be even less than 1 GB/s. The best was in versions 6.2.x, there the SSD reading speed often exceeded 6 GB/s.

BTW.Does a machine reboot work properly in Fedora 40? With me on Fedora 39 since kernel 6.6.x, the system crashes after reboot, turns the fans on to the max and I have no video signal on the HDMI of the embedded card. I have to turn off Talos II from the Power button and turn it on again.

Great news, unfortunately the 6.8.x series kernels perform poorly with SSD, below average from the last two years

Operating Systems and Porting / Unexpected suspend of Fedora 39 on Talos II

« on: January 15, 2024, 01:42:26 am »

After switching to the 6.6.9-200 kernel, I started getting unexpected system transitions to the SUSPEND state and then I could not restore the system to normal operation other than by shutting it down and turning it back on.

I found the solution quite easily, this affliction happens on Fedora on different platforms. The problem is solved by executing the following commands:

Code: [Select]

$ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
