Jerky scrolling in Chrome, FF, Brave, VimB
by Philip Rhoades 30 Oct '21

30 Oct '21

People, I have had a reasonably powerful PC for the last few Fedora versions: i7-7700K CPU @ 4.20GHz 8 core 32GB RAM 40GB Swap 50% free on 4TB Seagate drive and even though the PC seems unloaded according to Glances eg: < 40% CPU loading < 80 RAM used ~ 1% Swap used - Disk IO minimal I still have problems using the up / down cursor keys, PgUp / PgDn keys, mouse wheel for moving around on web pages - there is usually a second or more delay and then a jump . . Admittedly I do tend to load up the browsers with multiple windows and tabs but if the system still seems unloaded, why is there the jerkiness? Prior versions of Fedora were XFCE4, current F34 is Wayland and Sway but the problem has been there over multiple versions . .

I think I fixed it. Wireplummer was not being started. I did: systemctl --user enable wireplumber.service Now I think it's working.

Update to F35, no audio!
by Neal Becker 29 Oct '21

Just updated F34->F35 and now I have no audio. Tried under kde and then gnome. Seems there are no audio devices. F34 was working with pipewire. How can I troubleshoot? Thanks, Neal

Debugging USB device issues
by Philip Rhoades 28 Oct '21

28 Oct '21

People, I didn't get a response to my previous Q re an apparent problem with getting gphoto2 to work with my GoPro Hero 4 Session camera - I hadn't used the camera for a while and I thought maybe the Fedora upgrades since then were the cause of the problem - but maybe the problem is actually with the USB port on the camera? (gphoto2 used to work). The camera actually charges OK through the port and I can record videos and then move them to Fedora by moving the SC card to a card reader, mounting the dir and copying video files to the HD so the camera itself and device charging seems to be OK. I am getting nothing recorded in /var/log/messages when I plug in the GoPro and push its power button (plugging in any other USB device is working of course) so maybe it is the USB port on the camera that is the problem? - is there any way to debug that from the Fedora workstation?

partially invisible back-up DVD.
by home user 28 Oct '21

28 Oct '21

(fedora-34; gnome) The evening before doing a Fedora upgrade, I do a user data back-up. I do it as a data project in K3b to burn a DVD/Blu-ray (BD-R). I always "test" the back-up immediately after it's done. On April 07, 2021, I did such a back-up. I upgraded from f-32 to f-33 the next day. Today, when I put the disc into the drive, it automatically mounts and asks if I wish to view contents in Caja. In Caja, I successfully viewed an image stored on the disc, launched in Firefox an html file stored on the disc, and opened in LibreOffice a LibreOffice file stored on the disc. The disc was successfully unmounted and ejected when I asked Caja to do so. Also today, if I launch Files and then put the disc into the drive, it automatically mounts the disc. In Files, I successfully viewed an image stored on the disc, launched in Firefox an html file stored on the disc, and opened in LibreOffice a LibreOffice file stored on the disc. The disc was successfully unmounted and ejected when I asked Files to do so. On October 13, I did a user data back-up. Immediately after, I "tested" the back-up. 1. When I put the disc into the drive, nothing showed up on the screen. But I then launched Disks, the disc was there and mounted; it unmounted and ejected the disc when I told it to. 2. When I launched Files and then put the disc into the drive, the "+ Other Locations" flickered once, and that's all. But when I then launched Disks, the disc was there and mounted; it unmounted and ejected the disc when I told it to. 3. When I launched Caja and then put the disc into the drive, a message popped up "Unable to mount .F33_20211013 An operation is already pending". But when I then launched Disks, the disc was there and mounted; it unmounted and ejected the disc when I told it to. 4. When I launched Disks and then put the disc into the drive, the icon for the drive showed a disc. When I clicked that disc icon, it showed it mounted. When I clicked the mount path that showed below the graphic part of Disks, it launched Caja. I then successfully completed the "test" just as I did with the April 07 back-up disc, except that I had to use Disks to unmount and eject the disk. Also, I was able to restore a files from the back-up disc when using the Caja instance launched by Disks. I went ahead and upgraded from f-33 to f-34 the next day. Today, when I repeat steps 1-4 above using the October 13 back-up, I get the same results. Both back-up discs are Verbatum MDISC BD-R Blu-ray Disc, 25GB, 4x speed. Both were written with the same drive. What went wrong, and how do I fix it? Thank-you in advance. Bill.

Growing shared memory leak?
by Jordan Metzmeier 26 Oct '21

26 Oct '21

I am trying to determine if a problem I am experiencing is a bug or if there is something I am missing. Last week I found that 15GB of my 32GB RAM was used by shared memory, causing my system to fill swap. After about 1hr of trying to discover the reason for this, the only thing I could find was that `df` was indicating that space was being used by tmpfs mounted on /tmp, but I could not find files that came anywhere close to this size. Now I am inspecting my system after a few days of uptime and have found that shared memory is slowly growing again. It's currently up to almost 4GB: jmetzmeier@localhost:/tmp $ free -m total used free shared buff/cache available Mem: 32065 9493 2185 3920 20386 18204 Swap: 8191 2114 6077 When I check df, what's reported as used on /tmp is pretty close to my shared memory usage: jmetzmeier@localhost:/tmp $ df -hT /tmp Filesystem Type Size Used Avail Use% Mounted on tmpfs tmpfs 16G 3.5G 13G 22% /tmp However, `du` does not show 3.5GB of files inside: jmetzmeier@localhost:/tmp $ sudo du -sh ./ 32K ./ Does anyone know what could be happening here? Does writing a file to tmpfs and then deleting it cause the tmpfs to retain that allocated memory until reboot? My system is running Fedora 34. I have ensured nothing is mounted over top of /tmp and hiding files. Thanks, Jordan Metzmeier

router silence.
by home user 26 Oct '21

26 Oct '21

(maybe OT) (dual boot: fedora-34 and windows-7; gnome) Usually, I use my home workstation with a direct ethernet connection to my modem. A yellow cable goes from the modem to the yellow receptacle on the back of the tower. Occasionally, I go through a router. The yellow cable goes from the modem to the yellow receptacle on the back of the router, and a blue cable goes from any of 4 black receptacles on the back of the router to the yellow receptacle on the back of the tower. This has worked fine for a few years now: for the tower (both Fedora and windows) and for my ipad. But now it does not work: not for Fedora, not for windows, not for the ipad. Fedora shows no connection; I've found no way of diagnosing the problem. The ipad seems to sense the wifi signal, but there's no hint of data (all attempts to use the internet time out); I don't know of any way of diagnosing the problem. In windows, the indicator shows no internet connection; its diagnostic tool says something about "teredo" being disabled? deactivated? by the sysadmin. Using the router last worked in mid August (fedora-33 on my workstation). I did not attempt to use it between then and this past Wednesday. The upgrade from f-33 to f-34 occurred between the last time I successfully used the router and the first time it didn't work. Is that just a coincidence, or did the upgrade have something to do with it? How do I get my workstation, ipad, and the router working? For the f-33 to f-34 upgrade, the tower was connected directly to the modem; the router wasn't even powered up. But might f-34 have done something to the router when I connected them? The router is a D-Link AC1200; it's between 3 and 4 years old. Thank-you in advance. Bill.

F33 => F34 - gphoto2 not working?
by Philip Rhoades 25 Oct '21

25 Oct '21

People, Upgrading from: F33 / Xorg / XFCE to: F34 / Wayland / Sway seems to have caused gphoto2 to stop working (it does not discover any device plugged into a USB port) when I plug in my GoPro Black 4 now. I can't see why Wayland and Sway would make a difference - what else could it be? I used to be able to plug the camera in, see the red light for charging, wait until it was fully charged and the light went out and then push the button to get the USB connection. I am not 100% sure but the little LCD screen seems to be displaying something different now - a power plug icon plus the USB icon - I seem to remember it was different before but Googling didn't help . . Any suggestions for debugging would be appreciated! Regards, Phil. -- Philip Rhoades PO Box 896 Cowra NSW 2794 Australia E-mail: phil(a)pricom.com.au

Re: Does the program llvm break all the hardware or only some of it ?

What are "c scripts"? What has the number of "c scripts" got to do with Fedora crashing? It sounds like you corrupted your machine or broke some hardware more than anything else. Llvm is a compiler suite, and has nothing to do with VMs. This does not make sense on multiple levels. -- John Mellor

Startup recovery
by Dave Close 23 Oct '21

23 Oct '21

Not sure how to title this issue but I'd appreciate advice. A laptop running F34 crashed last night and won't start properly since. The only errors I can see and find in the logs indicate some unknown issue mounting the /home filesystem. The system has /boot and an LVM partition with / and /home. / and /boot mount successfully but the startup drops to emergency mode. After I enter the root password, I can run "vgchange -a y; mount /home" and /home is immediately mounted successfully, no problem. I can then issue ^D and the boot seems to complete. However, the network is not started and no gettys are running on other PTYs. It seems apparent to me that there is no problem with the LVM partition or the /home filesystem. So I don't understand why startup is failing nor how to discover the true cause. BTW, and not likely related, but if I try to boot from the latest kernel (5.14.11), the screen goes very dim after the mode is changed, making it very hard to see what is going on, and the keys to brighten the display seem inoperative. Booting from kernel 5.13.19 doesn't have that effect though the same startup problem happens. Off to get a COVID booster in the morning so further investigation will continue after I return. -- Dave Close, Compata, Irvine CA +1 714 434 7359 dave(a)compata.com dhclose(a)alumni.caltech.edu "Quantum computing is a marvelous way to show the non- intuitive nature of quantum mechanics." -Gordon Moore
