Re: [gentoo-user] SSD or MoBo playing up?
You also might try a known good power supply as well. You should definitely try the drive on another system if you can't do that, and/or try another drive with the current mother board. With the errors being different over time it could easily be nearly any component in the system. Symptoms are sometimes misleading, trouble shooting is difficult for most people, sometimes even for people who are usually good at it and experienced. Root causes are often obscured and failures can propagate in unforeseen ways even for the experienced. Testing suspect components in another system and/or substituting known good components into the failing system are the most useful for trouble shooting, but you have to remember what you've tested and what it suggested and recheck when it doesn't make sense. -- “The whole world is watching!

It could be that for some reason only one core is actually running. One way to test that, start compiling gcc or something and run htop. If setup right, it will display a bar graph for each core/thread. If you don't see the number that you should, then yea, the kernel config could be a issue or the mobo settings one. I'm sure someone with a similar setup will share a config soon. Just something you might want to check in the meantime. Dale :-) :-)

I see that currently gentoo-sources only includes 4.x and 5.x sources. Thanks, raffaele I use a 3.18.40 kernel, currently, on one of my AMD systems. It has thousands of source build packages, not only from portage but many others. Occasionally, I have to use another AMD system, with a newer kernel. I have many old codes, centric to a version 3 of the kernel, that would be a massive pita to move to a 5 version of the kernel. There are plans, as many are related to hybrid-optimized cluster that are NOT centric to the popular cluster codes. Home made 'systolic array processing' is just one legacy collective of old codes, I still use. Many embedded (gentoo) devs still use very old linux kernels for a wide variety of reasons. Products often developed do not change much, except to update the firmware for a strong reason. Thousands (millions?) of companies use very old linux codes, including kernels for a plethora or reason. They just do not publish it. The old stuff, if beautiful compared to much of the bloat-ware we have today. From linux kernels to cluster*. I still run codes on 386/486 machines, just for grins and as a seed for codes that are minimized. IoT from the big vendors is so bloated, they cannot even find problems. Old embedded (gentoo) linux codes run so fast, reliable and easy to collect performance data. You go down this path, its a game-changer. An addition, as minimalist coding and small, secure executables are an artform. Most of the semiconductor manufactures, are *ALWAYS* looking for those types of coders. Hello (TI)! So, YES old gentoo is very alive amongst minimalist and corporations. ymmv. I've run into many that keep incredicle trees of old, reliable codes. They are often much easier for an EE to use in verification of functions, Micro-Controllers, FPGA, etc etc etc. hth, James

It will be difficult to mount a big sheet behind me, but I managed to get some transparency (eg. hiding my background) using: first: Luma Key (both max sliders all the way to the right, and both min sliders all the way to the left) second: color key - I chose white as colour (#ff) - then the values as follows (top to bottom): 366 , 50 , 100 , 0.00 , 0.00 , 0.00 third: crop/pad to reduce the image to only show me and a little around it If I then add an image (chose a random one) as 2nd source, my background is really difficult to identify, but I can be identified. I think my face would be better if I would be less pale, but for now, I am happy with the result. -- Joost

I did notice that if the resolution is too large, I get a black screen. The largest I managed to get working is 640x360. Bill, you might be able to get video by sending it through OBS as well? I unmasked "media-video/obs-studio" and "media-video/obs-v4l2sink" (Latest version, except for ) Don't forget to apply the patch Neil mentioned in his email. I added the "v4l" USE-flag to "media-video/obs-studio" When all is installed, load the v4l2loopback driver with: # modprobe v4l2loopback exclusive_caps=1 video_nr=5 card_label="loopback" Then start OBS: # obs In settings, set "output (scaled) resolution" to 640x360 (You can find this under "VIDEO") Add your real webcam as video-source (set resolution to 640x360 if at all possible, OBS will scale on the fly if necessary. Start the V4L2 sink by: Tools -> V4L2 Video Ouput Set " /dev/video5 " as device and format " YUV420 " Then start "teams" and select "loopback" as the video-device. For me, this worked. Now only to find out how to add a different background and do other silly things. -- Joost

Ahh! Yes! I had seen the Virsh command which involves pausing a live image and then taking a snapshot of it. William's pointer makes sense. However, there is also the option to define a memory file as an object '-object memory-backend-file,size=1M,share,mem-path=/dev/shm/blah...' and this can be attached/detached/migrated/snapshoted/etc between hosts as desired. More details here (search for "Generic object creation"): https://qemu.readthedocs.io/en/latest/system/invocation.html > When using snapshots of live systems, I had problems restoring some of > the more active VM's which this avoids. > > > BillK Perhaps the technique with busy systems, other than pausing > snapshot, could involve using a migration of the image to a new location? As I understand it the newly migrated image will take over and start running in place of the old image, the moment the migration is completed. Scratching around I found the way to move an image from a qcow2 file on the host fs, to a raw format on a disk/partition. It is simpler than I thought (even with no libvirt): qemu-img convert -O raw image.qcow2 /dev/sda5 Or, the output can be 'image.raw' then keep a backup copy of it as a file and then dd it to a partition.disk. signature.asc Description: This is a digitally signed message part.

I got it to compile, at least it created a file named ones anyway. What
I'm unclear about, where is the if= for dd in the command? All the
commands I've seen before has a if= and a of=. The if for input and of
for output or target. I'm assuming that if I want to target sdb, I'd
replace null with /dev/sdb.
As I've posted before, even my scripting skills are minimal. Surprised
I got it to compile even. lol Just trying to make sure I don't mess up
something. I placed all this in the /root directory. I'm assuming I
can copy paste the commands above while in /root to make it work? I'm
asking because I haven't tried it yet.
Thanks.

I worked around this is Jitsi (it has background blur but not replacement) by using OBS Studio, which does all this and much, much more. With the plugin from media-video/obs-v4l2sink it creates a new "camera" with its output. That's a standard-looking /dev/videoX device and can be used with any software.
