Can't rename files in Files
by Chris Aitken 07 Mar '21

07 Mar '21

Sorry, I had sent my question to talk-request(a)gtlug.org. I guess that is why you did not receive it. I usually do an hour of research before I reach out to this group, just so you know. Thanks, Howard, for your response. I will check out your how-to. Quote: "Chris, I have posted a UNIX Command Line HOWTO on my website. I explain wildcards on it. http://home.eol.ca/~hgibson/UnixHowto.html -- Howard Gibson" Thanks, Kevin for your reply. I will try your suggestions below (however, renaming the file was not working for me, and that's why I originally reached out. Catch 22: Could not open file because of '?' and could not rename file because of '?' Quote: "Regarding the question, if you are using the command line you can use \ to escape the ? when entering the copy command. You could also use "cp -i start_of_filename* some_destination" then say yes or no as to which file(s) you want to copy. If you want to copy the file from a graphical desktop you can open the file browser program (e.g. caja in Linux Mint) and use it to select and copy the file. You may want to rename the file to remove the ? from the filename to make it easier to work with the file. -- Cheers! Kevin." Below I cut n pasted my orginal post and follow-up. I'm trying to play catch-up here while making the post make sense, chronologically: I'm getting input/output error at command line, as well as in the GUI. mv /media/owner/Storage/Pictures/HelenAlbum/1953?0000.helengr13grad17craigcres.jpg 19530000.helengr13grad17craigcres.jpg mv: cannot stat '/media/owner/Storage/Pictures/HelenAlbum/1953?0000.helengr13grad17craigcres.jpg': Input/output error On 2021-02-19 7:24 a.m., Chris Aitken wrote: > Now I can't access the folder contents.

Systemd dbus issues with cgroups V2 and USB-PS
by Russell Reiter 26 Feb '21

26 Feb '21

I recently installed Fedora 33 after in place system upgrades from 31 to 32 presented a host of issues with dbus-launch and now on F33, the danged mouse keeps losing power, not sleeping but turning off. uname -a Linux SOLON.ht.home 5.10.16-200.fc33.x86_64 #1 SMP Sun Feb 14 03:02:32 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux I had to install the Nvidia firmware on my Ti 1050 in order to access the kaffeine GUI which is a great wraparound for VLC. In the first system upgrade the GUI wouldn't launch from the desktop widget and from a terminal it said try export $(dbus-launch) so I did that and the GUI worked except that the video stream played outside the bounding box and rendered the point and click menu useless, I installed F33 and the Nvidia drivers and the dbus issues seem to have been abated, except for the mouse shutting off completely For a current session. if I do sudo echo -1> /sys/module/usbcore/parameters/autosuspend it apparently solves the problem for the current session however I'd like that condition to survive reboot. Ideally this would be in a systemd unit file. However I'm not sure where to make the change. I did try Lennart Poettering suggestion of adding a 61-autosuspend-manual.rules when he was rejecting certain bug reports and he mentioned that the issue is better solved in udev. I put this in a rule file but still, after a reboot and a certain amount of inactivity, the power to the mouse still shuts off. # Logitech Corp. Wheel Mouse Optical ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="046d", ATTR{idProduct}=="c077", TEST=="power/control", ATTR{power/control}="on" I want to avoid using a RUN feature from a udev rule because I'm not sure that a spontaneous disconnect could be used effectively to trigger a rule event, although that is what I'm considering. At this point ps xawf -eo pid,user,cgroup,args lists the following.

question re: bug filing
by o1bigtenor 18 Feb '21

18 Feb '21

Greetings I'm running a computer on Debian testing trying to stay somewhat current for updates. Setup using nouveau for my graphics running 2 graphics cards. LXQT is my desktop 'environment' (if that's the right word??). I'm also running Opera, Firefox LTS and Vivaldi for browsers. Tend to have lots of windows and a plethora of tabs open. Trying to always leave a window with the blank 'home' page to minimize JS issues. Running both uBlock and privacy badger trying to reduce my use information harvesting. Kernel 5.4.0-4 was the last kernel where I didn't find my second graphics card not able to move out of sleep. I did a system upgrade (using apt) more than once and then one did a 'apt autoremove' where the 5.4.0-4 was removed. This behaviour of my second card not coming out of sleep has become quite annoying - - it takes some 20 minutes to set most everything back up to like it was before the forced reboot. So where do I complain (bug report)? To me there is a confluence between the kernel, nvidia, nouveau, lxqt, the browsers and likely JS (although the multitudinous nefarious techniques used by various entities to try and control my computer from this last section would likely be disavowed by any and all involved). IMO this is not the kind of behavior that should be allowed for and by anything called stable (ie Debian is moving to a freeze looking toward a release of a new version of 'stable'). Suggestions? TIA

micro controllers
by o1bigtenor 16 Feb '21

16 Feb '21

Greetings I'm wanting to use micro controllers in more of an industrial setting. Don't want to spend the $$$$$$$$$$$ to get the officially hardened etc etc etc models. Looking for information - - - - - there's piles on using Arduino, Raspberry Pi but they're not really developed for serious use (one point - - - - almost always have to add a cape or a shield to get real connectivity - - - - don't need the the hp waste that's RPi so I"d rather not use that . . . .) Trying to find other ucontroller boards - - - - can find plenty of SoB - - - - but not boards. Hoping to use open source tools for the programming and control. Any suggestions as to where to look for this kind of stuff? Am I wasting my time? (I hope not!!) TIA Regards

grub2 on Fedora war story
by D. Hugh Redelmeier 16 Feb '21

16 Feb '21

Anything that can get more complicated will get more complicated. Boot loaders seem to be an example. It used to be straightforward to read /boot/efi/EFI/fedora/grub.cfg. Now, building the list of kernels for the menu is farmed out to blscfg (a grub module). I needed to have a Fedora box default to booting a kernel that isn't the latest (because the latest cannot bring up the display on my computer). 1. I needed to make updates not delete the working kernel. Normally updates keep only the last three kernels. As of today, two are duds. Fix: change /etc/dnf/dnf.conf's installonly_limit from 3 to 0 2. Find the list of kernels known to grub: sudo ls /boot/loader/entries/*.conf 3. set the default to one of those. Use the filename, without the directory and without the .conf sudo grub2-set-default 2733f1c892a5422c98bdb188c4f62737-5.10.9-201.fc33.x86_64 I don't know how long this sticks.

Weird Bluetooth settings in Network settings
by Joseph Rocklin 13 Feb '21

13 Feb '21

Hi, I just finished experimenting with windows 10. Before I switched to linux, I disabled my wifi network card. I have no complaints. The problem is, now I have a new type of bluetooth connection that activates every time I boot. Even when I've disabled the bluetooth features in the command line (the service also), it comes up every reboot. I think it may have to do with my vpn connection I've implemented. I just don't know and would like to find out. Can anyone fill me in on the reason for these connections popping up every reboot? They are: Bluetooth: Dummy (ipv6leakintrf0) Dummy (pvpnksintrf0) Dummy (pvpnroutintrf0). Thanks for any replies. Joseph

Somebody (Trevor?) in today's meeting said that Alyssa is currently living in Toronto. She's done some impressive reverse engineerng of graphics drivers. For example: <https://www.phoronix.com/scan.php?page=news_item&px=Apple-M1-GPU-Triangle-A…> It would be great to invite her to attend or talk at our meetings.
