Hi Sandie, On 17/02/2023 16:07, Sandie via dorset wrote: The install has not found the web cam! I tested the camera in the shop before I bought the computer. On the Windows system it worked well. Application Cheese came installed on Ubuntu 22 but it couldn't see a camera so I uninstalled it. I have reinstalled, uninstalled quite a few times. There are 2 versions of Cheese on offer in the Ubuntu software menu. I tried both several times. Then I tried & installed an application called Cameratrls? It found a camera named 0 & worked not too well on one zoom call. Now it too has failed. I tried a little bit of commanding on terminal, from tips I found searching for help. However some permission/s were denied. I can't really offer much advice other than my own experience with Kubuntu 22.10, which I related earlier on this list with regard to another issue. I've been in the habit of upgrading to the latest version as soon as it is available and I duly upgrade 22.04 to 22.10 at the end of last year. I didn't notice it at first, but I lost the klipper icon in the task bar and after some experimenting I did a clean install of 22.10 (retaining my home partition, which didn't actually fix the problem, but that's another story). Anyway I too was unable to access my webcam. However, this came back after I had installed cheese. I see that you have tried cheese, so this is clearly not too much help, but I suspect that 22.10 had a bug (amongst others) relating to the camera driver, so maybe you need to visit the Launchpad site to see if there is anything relevant to your particular problem. A quick search using the term 'webcam' came up with a confirmed bug: https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/1788725 Best of luck. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2023-03-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

No, I think they're all to do with the single video camera. It's good that v4l2-ctl lists it. Running ‘v4l2-ctl -d /dev/video0 --all’ will show lots of information, for your interest, including ‘Format Video Capture’ giving the resolution. > now putting in lsusb command. > > Got this: > > Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub > Bus 001 Device 006: ID 05e3:0503 Genesys Logic, Inc.

Webcam’ which gives us the manufacturer's USB ID for your particular model, ‘05e3:0503’, which is something to throw into Google when looking for other people having problems. What is it that goes wrong? On Zoom calls, for instance. You could try running ‘dstat’ in a terminal before starting the call. You'll probably have to install the package. It ticks away printing a line showing how the machine is spending its time every second. Of particular interest is the amount of idle CPU time, ‘idl’. If that gets too low for too long during the call then it could be Zoom, or whatever, is trying to do too much compared to the machine's power and the resolution of the video. So if cameractrls lets you lower the camera's resolution then that's something to try. Halving the width and height quarters the amount of pixels to process. > I've been out to the mercado & turned off all things except for > thunderbird & computer woke up from hibernate??

All the programs which want to use the camera's picture or change the camera settings use the V4L2 layer of software, Video for Linux version 2, so it doesn't matter whether you have Cheese installed, Cameractls, or whatever. They're all different ways of accessing the camera through V4L2. > When you have time let me know what your diagnosis is.

VLC works most of the time. After adding ffmpeg,then ffplay /dev/video0 works use this to determine ident: v4l2-ctl --list-devices that is double hyphen before list. Fixing sound output. Renamed /usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf, and on next startup it created a new file and was good. -- Next meeting: Online, Jitsi, Tuesday, 2023-03-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

Hi Sandie, > I attended 1 of your pub meetings in August '17 I recall; you chatted to Tim quite a bit about recovering some photos from a password-guarded USB stick. > installed via a disro created on a usb Ubuntu 22. For the record, Was that 22.04 or 22.10? Running lsb_release -a should say. > Then I tried & installed an application called Cameratrls?

Based on https://wiki.archlinux.org/title/Webcam_setup, which I know is for Arch Linux, not Ubuntu, but lots is similar, can you give us the output of v4l2-ctl --list-devices If you don't have that command then try installing the v4l-utils package. Also, a list of the USB devices, including the internal ones which should include the camera, would be useful. Running lsusb will give that. Others will hopefully have advice on the others problems like hibernate. I thought I'd just pick one ‘simple’ thing to start with. :-) -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2023-03-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
