---------- Forwarded Message ---------- Subject: [luv-talk] LUV status (& online meeting possibilities) Date: Monday, 10 August 2020, 2:55:53 PM AEST From: Rick Moen via luv-talk <luv-talk(a)luv.asn.au> To: luv-talk(a)luv.asn.au Robin Stephens asked: > Is luv-main still the primary place for discussion of all things Linux > in Victoria? It kind of is (to my knowledge). As you perhaps observed, it's reasonably active, with over a dozen postings over the course of July. I'm going to return to your point via a seeming digression, so please bear with me: Point 1. My friend Michael Paoli has been doing fine work collecting a list on Bay Area Linux User Group's (San Francisco) wiki of all known recurring virtual LUG meetings, during the pandemic era. It's here: https://www.wiki.balug.org/wiki/doku.php?id=balug:covid-19 You will note there's nothing (yet) from Oz: not Vic, not NSW, nothing. This is perhaps accurate, perhaps not. Truth to tell, I was just now double-checking all of LUV's public mailing lists and Web site to see if there were mention of a LUV online meeting. (There is not - yet.) As I find time, I intend to check other Australian Linux sites to see if any ought to be added to the page. Please, if you (plural) have a chance, kindly do likewise. That was the _initial_ point I wanted to make. Point 2: Hmm, one silver lining of the slow trend of rolling out online meetings (on Zoom, Jitsi Meet, or others) is that suddenly physicality is less important. I have lately been attending a number of organisations' Zoom or Jitsi meetings that are thousands of kilometres away from me. (Yr. humble servant is 60 km south of San Francisco, and his time zone during this season is UTC-7: Locals call it PDT = Pacific Daylight Time.) Recently, for five days at the end of July, I helped run the annual World Science Fiction Convention ('Worldcon'), a volunteer-owned/run literary and fandom event, held this year in Wellington, Enn-Zed. But, of course, 2020 being the dumpster fire that it is, few of the ~2000 attendees could be in Wellington, so this was the first-ever virtual Worldcon, held using a mix of Zoom, Discord, WordPress, Jitsi Meet, and some other technologies. (I did the buildout & administration of Jitsi Meet for the Worldcon.) Starting during staff planning and running through the event, I kept a browser tab open to https://www.worldtimebuddy.com/ , to keep an eye on the two timezones: I came to think of NZ, being on NZST = UTC+12, as five hours behind me plus a day ahead. (It seemed humourously fitting for the Worldcon to be held in the future. ;-> ) LUV / Melbourne / Vic, being on AEST = UTC+10 during these winter months, I would naturally think of as seven hours behind me plus a day ahead. As a mnemonic, you see. (I also switched to 24hr clock notation, as it makes the maths easier.) To sum: The jiggering of time differences is irksome but one quickly finds heuristics & tools to cut the annoyance value, and reduce error. The conclusion: How about other LUV people joining me in showing up at select virtual LUG events with little regard to distance or national borders? (I _am_ a longtime LUV person, even if I am Yet Another Bloody Yank.) Point 3: Also, please consider looking into occasional and perhaps regular LUV meetings on Jitsi Meet (like: meet.jit.si/luv) or on Zoom. Then, you (or I) can add them to Michael Paoli's list, and (for better or worse) gain international attendees with peculiar accents. I would be glad to give a virtual lecture on the construction, care, and feeding of Jitsi Meet for LUV. (I could be LUV's first monthly speaker to ever give a presentation to LUV's audience from 12,600 km away.) (If Russell or another LUV officer considers this posting appropriate for luv-main, great. I didn't want to presume.) _______________________________________________ luv-talk mailing list luv-talk(a)luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-talk ----------------------------------------- -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Additional info, Gnome 3.30.2
by Mark Trickett 19 Jul '20

19 Jul '20

Hello All, I forgot to mention the display manager, which is also where significant issues about the UI arise for me. The old Windows 3.x interface was limited, but functional. Gnome, and others, did add and improve, but the latest iterations have forgotten usability as much as the much reviled Windows 10 "tiles" interface. Some of my query does address issues with Gnome, and I am open to discussion of alternative window/display managers that might be more like what I am used to. Regards, Mark Trickett

32 bit CAPT printer driver under 64 bit Debian Buster
by Mark Trickett 18 Jul '20

18 Jul '20

I have had this Canon LBP5050N printer quite a while, and it saw some use with a visitor running Windows on a laptop. I did try to get it up and running in the past, but the printer driver is something of a nightmare to install even on a 32 bit system. Why persist, because it is a photo quality colour laser printer, it will connect USB, but as the N at the end of the designation indicates, it has a network connection. Any help would be appreciated. Apart from that printer, I will be sorting out a HP LJ4+ with a network card, not genuine HP, and may need to alter the IP address it currently has, along with another obsolete colour laser, but I gather that the support for Brother is much easier.

Scanner success, or so far
by Mark Trickett 18 Jul '20

18 Jul '20

Hello All, I have managed to do a scan with scanimage from the command line, this was what worked for me. <quote> I experience the same problem with 1.0.27-3.2. Inspecting the udev rules, I found that the file 60-libsane.rules is missing a line to apply permissions to the device if it has been recognized. Such a line is present towards the file’s end in older versions: ENV{libsane_matched}=="yes", RUN+="/bin/setfacl -m g:scanner:rw $env{DEVNAME}" Putting this line into a file /etc/udev/rules.d/65-libsane.rules allows scanners to be recognized normally after a reboot. -Juergen <endquote> I copied the line and put it in the correct file, owned by root, and group of root, and it is working. There are no other files in /etc/udev/rules.d/ where I was expecting to find some. I then unplugged the scanner, and plugged it back in. This is the LIDE 210, and tomorrow I will try the LIDE 120 that the earlier backends for sane would not support. Regards, Mark Trickett

Scanner works, and does not
by Mark Trickett 18 Jul '20

18 Jul '20

Hello All, An "interesting" scanner issue. I have been reading up on Debian bug reports, and there is similarities, but also differences. I am using Debian Buster, I think it is up to date, I can scan with Simple Scan, but not with scanimage from the command line. I have found the scanner with lsusb, the permissions look right, and looking at other bits, I cannot see any obvious fault. I have not had to add myself to the scanner group in the past, and it appears that may not fix the issue from reading. I would appreciate comments and suggestions. Regards, Mark Trickett

Resizing the whole screen with Debian 10 and Wayland
by Mark Trickett 18 Jul '20

18 Jul '20

Hello all, I am having a few problems with Debian 10 (Buster) 64 bit, the image, even during the boot sequence, more than fills the screen. I loose some of the text off the left edge of the screen, and more all round once up and running with Wayland, including the top bar. I also am having trouble resizing windows, currently Firefox is running maximised, but I want to reduce it a bit and I am having trouble getting any response. It is running on an AMD Ryzen 5 with 16 Gb of ram, and Gigabyte Nvidia Geforce GT 710 video card (NV106) driving a 24" LED Wintal 12V TV. While I can comprehend what Wayland is trying to do, and why, I am finding the discard of the older metaphors and way of working to be a serious "bug". They do have some excellent ideas, the top left corner hotspot is not intuitive, at least at first, and the new "menu" is not without merit, but such abandonment of prior ways of working is more than just irritating, it gets in the way of doing things. Regards, Mark Trickett

KVM pc-i440fx-5.0 vs pc-q35-5.0
by Russell Coker 14 Jul '20

14 Jul '20

https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-libvirt-config… For KVM, QEMU, and some other AMD64 virtual machine systems that use QEMU code you have a choice of pc-i440fx-5.0 (default) and pc-q35-5.0 for the machine type. The command "kvm -L help" gives you a list of machine types. The above URL is the only one I could find mentioning the difference, it says that "q35 is an Intel* chipset and includes PCIe, supports up to 12 USB ports, and has support for SATA and IOMMU". https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-vir… I have the virtual IO drivers for storage (included in Linux by default and available for Windows at the above URL). I use the curses terminal for Linux VMs and am experimenting with VNC for Windows VMs so don't need USB keyboard and mouse. I don't need passthrough PCIe and the IOMMU only matters if you are running a hypervisor not for a guest. So would there be any benefit in using q35? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

I have some 2 port PCI 100BaseT cards. These are sometimes really useful (and were expensive), but most machines only have PCIe nowadays. Email me off-list if you want some. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
