The (bad) state of Qt on GNOME / Wayland
by mario futire 07 Nov '20

07 Nov '20

I am developing a Qt app in Fedora 31 using the default GNOME wayland session and I am very sorry to see the state of Qt in this configuration. 1) qt creator crashes often (https://bugzilla.redhat.com/show_bug.cgi?id=1773356) the crash report tool does not seem to help 2) drag & drop does not work in Qt creator (and in no other Qt app) (https://bugzilla.redhat.com/show_bug.cgi?id=1774762 and https://bugreports.qt.io/browse/QTBUG-80303) 3) main window geometry cannot be restored when the application restarts (https://bugreports.qt.io/browse/QTBUG-80612) I think GNOME / Wayland / Qt it is just not ready and should not be offered as the default desktop session for Fedora. If I force Qt to use X11 emulations, things are much better. Probably Qt is responsible (but in the bug reports someone says that KDE / Wayland works well), and GNOME is not Qt, but there are so many Qt apps, that sending new users to a non working environment re-enforces the fact that "just works" is not true in Linux.

how to install zoom client.
by home user 04 Nov '20

04 Nov '20

Good morning, (f-29) (background) Last week, I was to participate in a "Zoom" meeting for a charity that I'm involved in. I have the needed software on my rarely-used windows-7 box. But I could not complete the windows-7 login (some problem with a windows-7 service). I've since found there is a "Zoom" client for Fedora. "dnfdragora" does not find anything for it. But I found a web page that I hope has what I need. I've downloaded the package ("zoom_x86_64.rpm"), and I've downloaded a "Public Key" ("package-signing-key.pub"). The web site from which I've downloaded these also has a line: Key fingerprint: [some 40 hex digit number] (4 questions) 1. Do the 2 files need to be in a specific place to do the install? If yes, where? 2. Do I need to be "root" to do the install? 3. What do I do with the "Key fingerprint"? 4. How do I do the install (preferably using "dnf")? thanks, Bill.

Firefox stability?
by Max Pyziur 07 Oct '20

07 Oct '20

Greetings, Lately, I've noticed that different tabs that I have open in Firefox are crashing. This seems to have started recently. They can be restored easily, but there's a nuisance factor here.

resume from suspend to RAM not working properly with / on btrfs
by Lukas Middendorf 28 Aug '20

28 Aug '20

Hi, TL,DR: I have problems with resuming from suspend to RAM on my new Ryzen computer. I have only seen this happen if I put root onto a btrfs subvolume, not on ext4. The proprietary nvidia driver seems to be one additional factor, but I have also seen this with the nvidia driver removed. Experienced something similar? I have upgraded my PC with a Ryzen 7 3700X, Asus ROG STRIX x570-E Gaming and a Samsung 970 EVO PLUS NVMe SSD. The existing Fedora 32 system from my old SATA SSD worked flawlessly (with suspend to RAM). For the last years I have always used ext4 (previously ext3) on monolithic root partitions (no separate /boot or /home, but separate data partitions) on mbr partitioned SATA disks, booting in legacy BIOS mode. With the new drive I wanted to make the switch to GPT, UEFI boot and btrfs (ext4 /boot). I didn't want to install a new system (with those months of finding programs you have not yet installed) but opted to just copy over my old F32 system. So I used gparted to set up the GPT and a 200MiB EFI System partition, three 500MiB boot partitions (for different distributions or Fedora versions), a 16GiB swap partition and the rest of the drive as btrfs. In the btrfs volume I created a fedora32 subvolume with a nested home subvolume. I then mounted everything (/, /boot, /boot/efi) on my old f30 system and copied over everything from my f32 partition. After bind mounting /sys, /proc and /dev I chrooted into the new copy, adjusted the fstab, installed all efi related packages, ran grub2-mkconfig and made sure the kernel paths in /boot/loader/entries were correct. I then switched to the system rescue mode of a f32 netinstall USB drive booted in UEFI mode (to get access to the efivars) to install grub with target x86_64-efi and regenerate the initrds. After that everything booted up and seemed to work until I tried suspend to RAM. It went to sleep properly, but resuming did not complete. After waking up it just continued to display the last four kernel messages of the suspend action (suspending processes, ..., suspending terminal). It reacted to emergency sync sysrq (HDD LED blinking) but the other sysrq keys did not seem to work ("u" also provoked a blinking LED sometimes). This happened from within KDE as well as from text terminal with systemctl suspend. Log files after reboot just had entries until shortly before suspend (processes suspended, all except the last CPU core disabled, unneeded drives stopped) but not from the attempt to resume. I assumed this to be caused by the NVMe-SSD and unsuccessfully tried some suggested solutions that have worked for others with suspend problems with NVMe-SSDs (disabling acpiphp, disabling d3cold_allowed). Since I had too many variables I trashed the content of the new SSD and started anew with a mbr partition table to boot in legacy BIOS mode. I just plain cloned the original f32 partition to the NVMe SSD, adjusted the fstab, updated grub.cfg, recreated the initrds installed grub to the mbr and everything worked, including suspend. I then again did another copy with btrfs root (and ext4 /boot), this time on MBR with BIOS boot and it again showed the previous suspend problem. No swap space this time. I also did a new install of F32 (from Everything Netinstall with Plasma Workspace profile) with btrfs root and ext4 /boot, which suspended correctly at the beginning but failed to resume after I installed the proprietary nvidia driver for my graphics card. Removing the nvidia driver (and updating grub.cfg and the initrds) returned that install to a working state. I then removed the nvidia driver also on the second non-working copy of my old system (checked that "lsmod | grep nvidia" does not show anything), but suspend still did not work. It did not show the kernel messages but just a black screen with frozen mouse pointer. So the nvidia driver seems to be one way to trigger it but there apparently are other ways to reach the non-working state. I have now trashed everything again and settled for GPT, UEFI and root on ext4 (no separate /boot) with /home on a btrfs subvolume as a compromise. This seems to be working fine. As I now have a btrfs /home my problem is also likely not caused by having files open on a btrfs partition. The problems were with kernels 5.7.9-200.fc32 and 5.7.10-201.fc32 . I should likely also have tried an older kernel, but have not yet done so (might try to get a new non-working test setup tomorrow). Nvidia driver packages were version 440.100 from rpmfusion on the new install and a rebuild of the f33 packages of 450.57 for the existing install. My hardware: - AMD Ryzen 7 3700X - Asus ROG STRIX x570-E Gaming (latest BIOS version 2407) - Samsung 970 EVO PLUS NVMe SSD - Geforce GTX960 Tested setups: Old Ext4 on MBR, SATA: working copy of old Ext4 on MBR, NVMe: working copy to BTRFS (Ext4 /boot, with nvidia) on GPT, UEFI, NVMe: not working copy to BTRFS (Ext4 /boot, with nvidia) on MBR, BIOS, NVMe: not working copy BTRFS (Ext4 /boot; nvidia removed) on MBR, BIOS, NVMe: not working new on BTRFS (Ext4 /boot, w/o nvidia) on MBR, BIOS, NVMe: working new on BTRFS (Ext4 /boot, with nvidia) on MBR, BIOS, NVMe: not working copy on Ext4 (btrfs /home, with nvidia) on MBR, BIOS, NVMe: working copy on Ext4 (btrfs /home, with nvidia) on GPT, UEFI, NVMe: working So this seems to be unrelated to the partition table type and the boot mode. If it is related to NVMe this is just one factor. I have just observed it with / on BTRFS. On a new install the proprietary nvidia driver is also needed to trigger this, but on my old install it also occurred with the nvidia driver removed. Things I have not tried yet (might try when I find the time again): - older kernel version - ext4 root but with separate boot partition (unlikely cause) - non-nvidia graphics card (don't have one) - logging kernel messages on different device using some serial output (there is a way, right?) to see what really is failing Has anybody else experienced something similar? Is there something I might have missed in the btrfs conversion process? This might become interesting with F33 with lots of new btrfs systems. Best regards, Lukas

VideoConference Package?
by John Mellor 27 Aug '20

27 Aug '20

In this extended period of Covid-19 isolation, is there a videoconference package available? Hosted systems like Zoom are not opensource, do not use a browser as a client, feed connection data to Facebook, only allow 2 participants for free, and not available for a local install. I thought of Webex, but its Cisco. Maybe its just me :-) I took a quick look at Jitsi, but users say it has a fatal extreme processor utilization bug, the rpm packages are 3 years out-of-date, and does not seem to be present in the normal rpm repos. I also took a quick look at BigBlueButtion, which looks pretty good. However, it only runs on an ancient version of Ubuntu, and uses a shell installer for some unknown reason. This seems like a major application type that appears to be completely missing from the repos. Is anyone building one, and just hasn't announced it yet?

Accidentally I hit ctrl-; in gedit and it brings up a window pane allowing the selection of emojis. I can't find this as a documented feature. What else am I missing? Also, can something like this be done in vim? Thanks, Max Pyziur pyz(a)brama.com

SPDIF sound in F32
by Greg Woods 02 Aug '20

02 Aug '20

After wrestling all day with an ASUS Xonar SE card (with accompanying Googling), I now believe that this card cannot be made to work in Linux. Stereo output through the green line out port works fine, but SPDIF does not. "lspci" actually claims this thing is a USB controller, although as I mentioned stereo sound does work. Does anybody have a PCIe sound card that is known to work with SPDIF 5.1 surround sound output? It has to be optical as those are the only digital ports on my receiver. One frustrating thing about trying to search for information online is that I come up with a lot of stuff that is way too old to be useful. For instance, a lot of the advice articles I found on getting sound working mention 4Front and OSS sound drivers, which is probably 15-20 year old information. I'm looking for first hand "yes I know this card works", or at least a pointer to something that isn't Ubuntu specific and is recent enough to be useful. Thanks, --Greg

dnf-automatic command_email failing to send email?
by Gunnar Niels 01 Aug '20

01 Aug '20

Hello, I'm trying to configure dnf-automatic to automatically upgrade my system on a daily basis and send me a summary via mailx using my mailgun account. I have mailx configured and functioning as expected; I can use the 'mail' cmd to send mail, and have other services using it to send mail. The following gist[1] has my /etc/dnf/automatic.conf; all I've really changed about it is to specify to use 'command_email' and uncommented the default 'command_format' and 'stdin_format', along with setting the from/to emails. I've dropped some debug logs into the python it runs, and I can see it gets to the emitter fine. I was even able to send an example email with the emmitter that was constructed by manually setting the subject and body and running `emitters[0].commit()`[2]! The error I'm seeing in the dnf-automatic.service logs is: Jul 29 06:45:16 <host>dnf-automatic[6226]: . . . message not sent. Is this is a bug or do I have something misconfigured? Would be much appreciated if someone could point me in the right direction.
