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.

What do you open .mobi files with??
by Beartooth 31 Mar '20

Something on sourceforge has been recommended to me, but I try to stick to things that dnf can install. Surely there must be some Fedora- native ebook reader! -- Beartooth Staffwright, Not Quite Clueless Power User Remember I know little (precious little!) of where up is.

Upgrade of F30 to F31 Appears to Have not Worked Correctly
by Stephen Morris 12 Feb '20

12 Feb '20

Hi, I have just upgraded to F31 from F30 using dnf system-upgrade download --releasever=31. Before I did the upgrade I updated F30 to the latest maintenance level. When I booted into Gnome on F31 there was no activities menu to be able to launch any application, the only way I could launch applications (if I knew the application command) was to use alt-f2. In F30 I was using dash-to-dock but in the F31 upgrade that failed to start. I did find an entry on the net saying that V66 of dash-to-dock had an issue in F31 with kde (plasma) but no reference to issues with Gnome. I was able to run Gnome-tweaks, see that it was flagging that it couldn't start dash-to-dock, the dash-to-dock settings were saying that it was V66, so I used gnome tweaks to uninstall it. I then used dnfdragora to install V67 of dash-to-dock when confirmed the V67 was installed and V66 wasn't, but when I went back into gnome-tweeks it was still saying that it was trying to start V66 of dash-to-dock. I eventually found that I had to remove all the gnome-shell extension settings in my home path, use dnf to uninstall dash-to-dock V67 and reinstall it for Gnome-tweaks to show that it was successfully able to start dash-to-dock V67. Also after doing this when I launched firefox it immediately asked me asked me if I wanted to update all my extensions from upstream except for dash-to-dock, which I did and that then activated all the extensions even though at update they weren't active. When I launch firefox V73.0a1 it displays with two windows overlapping each other displaying the same contents, forms being displayed on the screen are not displaying correctly in terms of when input is entered into text boxes the input is actually being displayed below the text boxes. Also the address bar keeps flashing on and off because the display of the web page being accessed is intermittently overlaying the address bar, consequently I can't actually select any menus displayed on the web page. Just for interest Thunderbird V73.0a1 doesn't seem to exhibit these issues. If I run the version of firefox from the repositories it exhibits the same overlay issues as well. When I run Gnome-terminal it exhibits the dual window overlay issue when maximised. If I run Gnome-terminal unmaximised it doesn't exhibit the issue, but if I manually expand the size of the gnome-terminal window it exhibits the overlay issue as soon as I type anything into the window. I tried reinstalling Gnome by re-installing the 'Gnome Desktop Environment' group from dnf but that did not make any difference. Does anyone have any ideas what the issue might be? If I run dnf system-upgrade download --releasever=30 will that downgrade me to a fully working version of F30 as it was before I did the F31 upgrade? regards, Steve

Some things that would make Linux/KDE better for me...
by linux guy 07 Feb '20

07 Feb '20

I'm running Fedora 31/KDE and it is great. Fantastic, actually. Kudos to the team that delivers and supports Fedora, release after release. Things just keep getting better and better and the update process is so smooth and easy. Especially compared to those other operating systems... However, F31/KDE isn't perfect. Here are a few things that could be better... 1) There is a bug that creates distortion in playing audio via HDMI monitors. I frequently have to do a pulseaudio -k to reset things. 2) There is a bug when running dual monitors and the left monitor is rotated and not the primary monitor. I have to start SystemSettings and force a reinitialization every time I reboot. 3) There is a bug wherein the HDMI monitor I want my audio played on isn't saved. It always wants to play on the first (left most) monitor. I have to start pauvolume and select my primary monitor every time I reboot. 4) It would be really, really nice if KDE remembered which desktop an application was on when you rebooted after doing a forced shutdown. For example, sometimes I have 30 Firefox browsers open on various topics, spread across 3 or 4 desktops, plus some PDFs in viewers and a few Konsole sessions and a few Kwrite documents... and a large update comes along that I need to apply that requires a reboot. Generally I do a #dnf update followed by a #shutdown -r now. When I reboot and login to a new session, Firefox allows me to restore all my open browsers, but it doesn't remember which Desktop they were on... so I have to manually sort them. Likewise Konsole sessions don't remember what Desktop they were in, nor the path they were open to. Would be nice if they did. 5) There is an unintended behavior whereby if I open a document fullsize on one screen, it goes fullsize on any screen I move it to. For example, I run a 22" monitor in portrait mode to the left of my primary 43" 4K monitor. I often fullscreen a document in the side monitor to refer to while I am working on something on the primary monitor. If I then drag the document from the side monitor to the primary 4K monitor, it goes fullscreen there. And then I have to resize it. It would be nice if it stayed the same size, pixel wise, when it moves from screen to screen. 6) My mouse doesn't move enough... My desktop is very wide. A side 1920x1080 monitor running in portrait beside a 4K monitor. I have my mouse speed/acceleration turned right up, but I often run out of space on my mouse pad before I can move across or even up and down my desktop. It would be nice if there was more speed/acceleration so less hand movement was required. Enough of the negative... how about some things I absolutely love about Linux/Fedora/KDE Plasma... 1) Putting a panel anywhere I want ! When you've got this much screen real estate, you need several of them. 2) Multiple desktops. OMG, I could never live without multiple desktops. So nice to be able to sort tasks into desktops and then jump from desktop to desktop to handle things. 3) The way task manager groups and displays apps in the panel. So nice... but... I wish there was a way to sort and search instances within a task list... like if I have 7 Firefox browsers open on a desktop, be able to arrange them in a certain order (gmail at the bottom, for example) or find all the browsers that have YouTube open in them. That sort of thing. 4) dnf update. Dnf in general. Has there ever been such a great package manager ? I can remember complaining going from Yum to DNF, but I was wrong ! I love how I'll get a desktop notification for updates, I can run dnf update (when I want), view what is available, stop the update, update select packages, etc. Updates work around me, I don't have to work around updates. And the update process is unobtrusive, it can generally run in the background without interrupting my work. (On a faster multicore machine, anyway.) 5) Konsole. I love me some Konsole sessions. Especially the way you can right click and open Dolphin in the directory you are working in from Dolphin. And especially how you can open Konsole from Dolphin. 6) The stability. I can start work on Monday and run all week without rebooting or even logging out. My computer never freezes or stumbles or loses data. It's fantastic. I never have to reboot and get organized again. I work. I go away. I come back. And everything is just the way I left it. 7) The ability to mount just about any file system ever. 'nuff said. I'll leave it at that. To say I am enjoying and appreciating Linux/Fedora/KDE these days is an understatement. LG

Tracking down SSH access
by Michael Eager 02 Feb '20

02 Feb '20

When I look at /var/log/secure or run journalctl on my workstation, I see failed SSH login attempts from a variety of IP addresses. The attempts are every 3-12 minutes. /etc/ssh/sshd_config contains: PasswordAuthentication no The workstation is on a LAN behind an EdgeRouter firewall. No Internet- accessible ports are forwarded to the workstation. The LAN has a variety of servers, NAS boxes, WiFi access points, WiFi-connected laptops, etc. A typical /var/log/secure entry looks like this: Jan 30 12:43:50 redwood sshd[21228]: Invalid user jackiehulu from 124.204.36.138 port 37394 Jan 30 12:43:51 redwood sshd[21228]: Received disconnect from 124.204.36.138 port 37394:11: Bye Bye [preauth] Jan 30 12:43:51 redwood sshd[21228]: Disconnected from invalid user jackiehulu 124.204.36.138 port 37394 [preauth] The corresponding journalctl is: Jan 30 12:43:51 redwood.eagercon.com audit[21228]: USER_ERR pid=21228 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=PAM:bad_ident grantors=? acct="?" exe="/usr/sbin/sshd" hostname=124.204.36.138 addr=124.204.36.138 terminal=ssh res=failed' I'm assuming that something on the network has been compromised, allowing SSH login attempts on the LAN. Other than turning off each server/AP/laptop/etc, one at a time, to find when the accesses stop, is there any way to find out where the SSH attempt is coming from? -- Mike Eager

Dear All, My new computer has got 2 disks: a SSD and a HDD one. The SSD disk is large enough to have Fedora and my entire home directory on that. Now, I am intending to use the HDD disk for backuping. And my question is: How should I format the HDD disk? Thanks in advance, Paul

Hey group! This might be way off topic, but I figured this is a kind of slow day! Putting together a "list" of what I think a reasonable set of functions/areas might be useful for a sys-admin to help setup/manage a web project for a distributed team. If you have a few mins, feel free to add/comment/delete regarding the list. thanks user admin functions system remote acces port issues ddos issues dns issues system update issues selinux/security dir/file user permission/security issues handle system services log file issues virus issues security/firewall remote monitoring package inspection/update/management network management/lockdown webservice apache/webservice setup cloudflare thanks for any/all inputs!

Ryzen CPU + ECC memory
by Germano Massullo 31 Jan '20

31 Jan '20

Can anybody with a Ryzen CPU + ECC memory show me the output of following command? # dmesg | grep ECC I am buying a Gigabyte X470 AORUS GAMING 7 WIFI in order to be able to use ECC capabilities, by the way Gigabyte documentation states: " ECC is only supported with AMD Ryzen and Athlon of PRO-series CPU." The problem is that PRO versions are OEM only, so I am wondering if I can use ECC capabilities with a regular Ryzen CPU... Thank you
