Current state of AMD/Radeon support
by Richard Shaw
With the AMD graphics card drivers being open sourced I'm considering
moving away from NVidia on my next graphics card purchase but I'm concerned
because of all the driver issues I've heard about on Windows.
Are the linux drivers experiencing the same problems or are they pretty
stable?
As much as I don't like depending on the NVidia binary drivers, I have had
VERY few issues.
Thanks,
Richard

rkhunter warning: real or false alarm?

This morning, I got the following warning from rkhunter:
-----

The output from "netstat -an" is too long to put here. I don't know
what to look for in all that.
1. What specifically should I be looking for?
2. Is rkhunter's warning a false alarm or a real problem?
thanks,
Bill.

Transfer my current Linux install to a new dual boot drive with
Windows ?
by linux guy
Hi people.
I'm about to purchase a new workstation computer because my current
workstation is too slow. The new computer comes with Windows 10 installed
on it. I rarely use Windows, but occasionally it comes in handy to
troubleshoot something, so I'd like to leave it on the hard drive.
Question: how do I transfer my current workstation installation to the
new hard drive and retain Windows ? I don't want to start over building
my workstation installation from a fresh install.
Thanks

Authentification error in kdm, gdm after rsync cloning an OS...
console fine.
by linux guy
Hello wonderful Fedora people. ;)
I cloned an operating system using rsync using the following, basically:
sudo rsync -aHxv --numeric-ids --progress root@brix:/* /mnt/drive
--exclude=/dev --exclude=/proc --exclude=/sys --exclude=/tmp --exclude=/boot
It worked fantastically well. I'll post the nity gritty details in another
thread once I confirm a few things.
Everything works perfectly, except that I can't log into a session with kdm
or gdm because of an authentication error. I can log into a console
session without any issues.
I have never been able to log into a session using gdm. The session
displays the user names, it allows me to input a password and then the
screen flashes and it returns me to the gdm screen.
I am able to log into a kdm session. When I first do I received several
SELinux errors and I am asked for the root password anytime I tried to do
anything. Other than that everything worked well.
The message is "Authentification is required to access the PC/SC daemon"
One of the SELinux erros was something about unix_chkpwd map
/etc/ld.so.cache and it gave me an option to fix it. I ran that command
and the SELinux errors seemed to have stopped.
Furthermore when I run passwd <username> and try to reset a password, I
get: Authentication Token Manipulation error.
What is going wrong and how do I fix it ?
Thanks

i915 bug in kernel 5.4.x, GUI complete freezes up
by Chris Murphy
Affects Skylake and Kabylake so far, I'm not sure how extensive it is
within each series, but as F31 has rebased to 5.4 I thought I'd give a
heads up. It's actually somewhat rare, I have an npm+electron chat app
that seems to hit this way more often than say Firefox (and I'm not
chatting near as much as I'm webbing).
[drm:gen8_reset_engines [i915]] *ERROR* rcs0 reset request timed out
https://bugzilla.redhat.com/show_bug.cgi?id=1780800
If you hit it, revert to 5.3.18 and if you want cc to the bug report
with CPU model. Another idea is to use a current 5.5.0rc, it's fixed
there but the backport is giving upstream devs some grief so I'm not
sure when it's going to get fixed in 5.4. I think part of the delay is
also the two holidays falling on Wednesdays :D

Dual Monitor - second monitor not working
by Simon Colston
Fedora 31
When installing, I had a Dell monitor attached to an nvidia graphics card via HDMI and that was working fine. I
installed the nvidia drivers for this.
I now want to use an old ViewSonic monitor as a second monitor so I plugged it into the on-board VGA port and booted.
The ViewSonic monitor is now the only monitor working. I adjusted the settings to make the display useable (Settings ->
Devices -> Displays) but only the ViewSonic monitor is listed here.
Google has led me to try this:
simon@hedgehog ~]$ lspci | grep -i VGA
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 630 (Desktop 9 Series) (rev 02)
01:00.0 VGA compatible controller: NVIDIA Corporation GP108 [GeForce GT 1030] (rev a1)
[simon@hedgehog ~]$ xrandr -q
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 16384 x 16384
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-1 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis) 432mm x 324mm
1600x1200 60.00*+
1400x1050 74.87 59.98
1280x1024 75.02 60.02
1280x960 60.00
1152x864 75.00
1024x768 75.03 70.07 60.00
832x624 74.55
800x600 72.19 75.00 60.32 56.25
640x480 75.00 72.81 66.67 59.94
720x400 70.08
** Note that there is an HDMI connector on the motherboard as well so I am not sure if HDMI-1 here refers to that.
I tried this:
[simon@hedgehog ~]$ xrandr --output HDMI-1 --auto --right-of DP-1
[simon@hedgehog ~]$
... but there was no output and nothing changed.
I would like to end up with a separate desktop on each monitor.
Any help gratefully received.

external hdmi, sleep on lid close buggy intel graphics
by Neal Becker
I have a lenovo x1 carbon (2014 I believe).
graphics is
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev
09)
This is F31
Using X, KDE.
(Also newer kde builds from name=Copr repo for kde owned by zawertun)
Detecting plug/unplug hdmi is unreliable. The only reliable way to get it
to work is switch to VT, then switch back to X.
Same for sleep on lid close. Only seems to work reliably if I switch to VT.
Over the years it seems to have gone from being somewhat unreliable, to
about 100% reliable, to now being quite unreliable.
Any ideas?
