Participantopenmamba is in fact a single maintainer driven distribution
I had no idea. Damn! You’re doing an incredible job.
The same may be applied to .spec files
This is what I had in mind, I had contributed to OpenMandriva a couple years ago and they accepted .spec files and relative patches. Their build system builds the package by pulling sources and compiling when necessary, then puts it on the repository. No uploading of binaries.
A contributor might want to start learning and creating packages for openmamba in his local environment and if you express that you have this interest the discussion might evolve into discussing the technical details on how to do this.
I would like that. And if necessary, I may host my own user rpm repository, with packages built according to openmamba standards.

ParticipantContributing by making packages which openmamba users might install would require by the way some sort of user identification for legal reasons. If there is interest for this we can go into more detail.
I am surprised by this. Is this a requirement of the openmamba project, or is it an actual european/local issue? I value my online anonymity

ParticipantI’ll try to be as precise as possible regarding what I did then. When you suggested to check the CPU frequency with
cpupower-gui
I did the following:1) fresh boot of openmamba. run
cpupower-gui
and noticed CPU being stuck at 800Mhz on all threads.2) sleep/wake the system.
cpupower-gui
shows CPU clock boosting correctly. Now I did update and a kernel update was included in the update. This doesn’t do good to isolating causes, I agree.3) rebooted. run
cpupower-gui
and noticed CPU boosting correctly.I was not aware that there is a
cpupower-gui-user
service. I do not knowcpupower
at all, I thought it was just a utility to show CPU behavior, I do not know if it actually does act on the CPU behavior.All I can say besides that is that this issue appeared in every installation of openmamba I have done on this system. I hope it’s gone for good on this installation!

ParticipantToday after a system update and a clean boot, the problem was not replicable any longer. Maybe a patch fixed it?
einar.hjortdal
ParticipantActually, I think
cpupower-gui
showed a lot! Thanks for the suggestion.After a boot, cpupower-gui shows each core is stuck at 800Mhz, after a sleep/wake it behaves as expected and boosts up to 4Ghz when needed.

ParticipantIn order to be able to help troubleshooting bad performances in openmamba installation itself it is adviced to report the issue when no custom software is installed and running
I would like to clarify: the issue shows even without user-installed VSCode and/or Microsoft Edge.
The slowdown can be clearly experienced with Dolphin and KSystemLog, for example.
It is however very obvious when VSCode and Edge are running because they’re more complex programs that use more system resources than anything else my openmamba installation has, as far as I know.
openmamba uses the LTS 6.6 kernel, if the hardware is recent it might be better supported by more recent kernel
The hardware is relatively old: intel i7 4790K and nvidia gtx 780, I do not believe kernel support is the issue.
So far I can consistently replicate the disappearance of the issue after one single sleep/wake cycle. Something clearly happens with that, but I don’t know what.
Every time I boot openmamba, I immediately put the system to sleep and wake it up, this resolves the issue until the next reboot.
Given that sleep/wake reliably solves the issue, do you have any guess for what to investigate?
A tool like cpupower-gui might help to check and set the CPU usage for appropriate performances in terms of clock frequency. When I/O is causing slowness, different things might be checked which I’m skipping here. When no system log errors are show, CPU and I/O usage are reported as idle while uncompressing but the user sees slowness it would be the kernel that is not working correctly.
I can verify if
cpupower-gui
shows anything before/after a sleep/wake cycle.-

ParticipantI have noticed that this issue seems to go mostly away after waking up the system from sleep, and logging back in with sddm.

ParticipantYes, I think you’re right. I was mistaken about Calamares, I apologize.
I would like to use openmamba as a server OS, but I need a more minimal install solution due to my current provider’s limitations on ISO size and storage, and lack of graphical acceleration.
einar.hjortdal
ParticipantI don’t think we understand each other here: are you suggesting that there must be a desktop to use a graphical install? It is possible to graphical install with calamares a system without desktop.
Typically, I rent a VPS, connect with VNC and install a minimal system graphically, then ssh only.

ParticipantHi, thank you for your answer. I guess I must wait for the new release of
xorg-drv-video-nvidia_470
to use openmamba, that’s a shame.
I accidentally rebooted and the os wouldn’t boot any more, I had to do a fresh install.I have many questions, I apologize.
Does openmamba have a bug tracker of sorts?
Does openmamba have a community chatroom?I am experiencing awful performance and I am not sure what is causing it. Everything is extremely slow, so I suspected some driver issue. Some people from another community where I asked for help suspected it could be graphics drivers.
To give you an idea: discord is often taking 140% CPU according totop
, the web browser is very laggy, everything looks slow and delayed. The new fresh install also took significantly longer than I would expect a linux distro to take to install.
I was running nouveau fine on AlmaLinux the past year on this same system, to me it seems like nouveau should be ok.
Do you have any suggestion on how to verify whether or not the graphics driver is indeed the source of these performance issues?-

ParticipantI would like to add that my system has both an intel graphics chip and an nvidia card.
glxinfo |grep vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: Mesa glxinfo |grep renderer GLX_MESA_copy_sub_buffer, GLX_MESA_gl_interop, GLX_MESA_query_renderer, GLX_MESA_gl_interop, GLX_MESA_query_renderer, GLX_MESA_swap_control, Extended renderer info (GLX_MESA_query_renderer): OpenGL renderer string: NVF1
It looks like I was suffering for awful performance because everything is being software rendered instead of using any of the available graphics chips.
