Fixed the mic
by Ted Pomeroy 06 Jul '20

06 Jul '20

NMGLugers, I had trouble with my mic in Xubuntu 20.04 during our July 2nd meeting. I have resolved this today, but the route was convoluted so I cannot be sure which step was the most likely single solution. My first choice for the solution is the Pulseaudio mixer where I found the "Input Devices" tab and un-checked the "Set as fallback" choice. As this was the last thing I did before a successful use of the mic to record a short test file I am fairly sure this was it. For the test I used 'arecord -t wav -d 10 testFile' as my command. This created a wave file of 10 seconds duration from the input device, ie, my internal mic. Another item I tried was to install the gui for the Alsamixer and to adjust the "Capture" level. It took a few tries in the Alsamixergui to get the Alsamixer to respond, but this is simpler than manually adjusting the /usr/share/alsa/alsa.conf.d files which was one solution suggested on the Internet. The Alsamixer gui only showed me "Master" and "Capture" levels, so not much to worry about. I have also added sox and lame, just to round out my audio capabilities. Now I get a robust response from the mic and will be able to join our meeting on the 16th in full voice with my Xubutu 20.04 install. By the way this is a 32 GB thumb drive so I can carry it around in my pocket. I will keep us posted on any learning I do, but still, I think it is easier for a general user to stick to the LTS version. Thank you, Ted P

Pandemic paces
by Ted Pomeroy 03 Jul '20

03 Jul '20

NMGLUggers, I will try to be bright and on time to the meet up tonight via the web. Our Governor has highlighted Pandemic problems nationwide and local, so I, for one, will not be interested in face to face [mask to mask] meetings for awhile. I am still having fun with updates/upgrades. Can comment tonight. Thank you, Ted P.

Next meeting Thursday
by Ted Pomeroy 28 Jun '20

28 Jun '20

NMGLugers, I have been updating both Debian and Xubuntu. On Debian I did the upgrade from Stretch to Buster. I encountered a program called 'minissdp' as part of the upgrade and had a few issues with it. It is designed to allow network awareness of Upnp, so it requires setting permissions to open a port for gathering data. I left it unconfigured during the upgrade, as this was allowed, but subsequent updating flagged it as partially installed. I finally removed it. With Buster running all other routine things I do seem to work, though I have not been using it long enough to rule out all problems. Updating now brings up warnings that the trusted gpg signatures do not match, so I will re-visit this issue which I had resolved in Stretch. I will be trying to sort out whether minissdp is needed or not and what to do to configure my apt files to correct the error messages about the trusted.gpg. I will have to research this and try to remember what I may have done to the keys involved. With Xubuntu I am using both 18.04 and 20.04 on different hardware. My thoughts on this are that I should try the six month release cycle, but my gut says I prefer the stability of fewer glitches and more gradual changes in the two year release cycle. The six month cycle gives newer kernel updates that bring the newest modules and controls. This has alerted me to learning more about systemd which is the control mechanism for the on the fly kernel adjustment and system administration. It also dawned on me that 'mount' no longer lists just the mounted devices, but lists the several mounted cgroups as well. If one needs to know hardware it is better to use 'lsblk' instead. And 'df -H' to see how much space is available on your drives. Systemd and control groups are new to me, so I will be reading the manual and looking at the tutorials to find out more as I go along. With the Xubuntu I will be trying to learn and catch up to the control group system, but I think I will settle with the LTS two-year cycle for updates as a rule and use a usb-installed system to see what the new, six month, release is doing. Where I tutor newcomers I will definitely favor the LTS version. We have a virtual meeting on July 2, at 5:30 pm, MDT. I will comment more on these issues and attend in Xubuntu 20.04 to see how that works. I do not anticipate any issues with the connection. We are still meeting virtually as noted on our website. Thank you, Ted P.

meeting tomorrow 06/18
by Ted Pomeroy 17 Jun '20

17 Jun '20

NMGLugers, We meet tomorrow evening. I hope all are well. I did do the swap as file on an instance of Xubuntu 18.04. It works pretty well for me. This is a usb install, so highly portable. I may change it to any upgrade after 20.04.1, but for now I am sticking to LTS. I've been helping a few individuals, but mostly with the gui menus, so not too deep. Otherwise I am doing well, but not doing anything too deep. It must be the warm weather. See you tomorrow. Thank you, Ted P

Swap file,
by Ted Pomeroy 15 Jun '20

15 Jun '20

NMGLUgers, I'm having trouble typing so apologies for the empty email just sent. I hope turning off the touchpad will fix that. I have just added a swap file to a usb install that I am using here. I made a few errors, but got through the process. I used the 'dd if=/dev/zero of=swapfile bs=1024 count=1048576' to create the space. Notes say this eliminates holes in the swap which would stymie the kernel. The info I used was from: https://linuxize.com/post/how-to-add-swap-space-on-ubuntu-18-04/ I had to add some steps to place my file in the root directory, rather than my home directory where I started by default. but it seems to be working. I was also on my way to system upgrade to 20.04, but will wait til the Updater allows this, apparently after the 20.04.1 release. Suits me, I'm not a fan of finding errors, though I should be. I prefer to wait till there is consensus and some refinement of a new LTS release. It is fun to add the swapfile, not a partition, as this is a new consensus. I will see how it works out on a usb that I use for portability and my own testing. Thank you, Ted P

Re: [nmglug] Freezing

Thanks again Ted, I looked for /boot/efi and there is a directory with many files. Below is how I got there. In the screenshot you can see Swap is using very little memory when I use my machine normally. The second screenshot shows the directory /etc/boot on the disk /de/sda1 and the linux file system on /dev/sda2. gparted has only two partitions (see below from gparted). So the question begs how swap memory is an issue at all? Here's the output of my digging for swap and not finding it in the directory as shown below, /etc/boot. I also found an ubuntu directory and listed the files. Again other than grub the results are Greek to me! :/boot/efi/EFI# ls BOOT ubuntu root@brian-VivoBook-ASUS-Laptop-X505ZA-F505ZA:/boot/efi/EFI# cd ubuntu root@brian-VivoBook-ASUS-Laptop-X505ZA-F505ZA:/boot/efi/EFI/ubuntu# ls BOOTX64.CSV grub.cfg grubx64.efi mmx64.efi shimx64.efi I am loathe to increase the swap memory when it doesn't appear to be a problem according to System Monitor. Anyway, here are my search results to find /etc/boot. /home/brian# cd /boot root@brian:/boot# ls config-5.3.0-55-generic memtest86+.elf config-5.4.0-33-generic memtest86+_multiboot.bin efi System.map-5.3.0-55-generic grub System.map-5.4.0-33-generic initrd.img vmlinuz initrd.img-5.3.0-55-generic vmlinuz-5.3.0-55-generic initrd.img-5.4.0-33-generic vmlinuz-5.4.0-33-generic initrd.img.old vmlinuz.old memtest86+.bin root@brian:/boot# cd efi root@brian:/boot/efi# ls EFI root@brian:/boot/efi# cd EFI root@brian:/boot/efi/EFI# ls BOOT ubuntu root@brian:/boot/efi/EFI# cd BOOT root@brian:/boot/efi/EFI/BOOT# ls BOOTX64.EFI fbx64.efi mmx64.efi root@brian:/boot/efi/EFI/BOOT# cd /boot/efi/EFI root@brian:/boot/efi/EFI# ls BOOT ubuntu root@brian:/boot/efi/EFI# cd ubuntu root@brian:/boot/efi/EFI/ubuntu# ls BOOTX64.CSV grub.cfg grubx64.efi mmx64.efi shimx64.efi Again, many thanks. Brian PS: this is not a serious issue as I can do a hard shutdown and boot up again. Next time I'm hopefully going to be doing nothing important and I can just walk away and see if the machine un-freezes. I'll let you know if I go that route and the results.
