Server denies user access -
by Bob Goodwin
I have a server running fedora that denies access to me as user "bobg."
I can ssh as root and have re-entered the "passwd" for "bobg" and it
reported "passwd: all authentication tokens updated successfully."
I also added an= new user and had the same result.
Am I being prevented from actually changing the password via ssh
perhaps? If so it's strange that it reports tokens updated successfully.
There's no display or keyboard attached,
I can still access view the contents with Samba and the samba password
but need user access for me. I suppose root access would wok but I have
spent all morning at this and don't know what else to do to fix the user
access problem.
Suggestions appreciated.

Cinnamon configuring the samsung ml-1660 printer as duplex printer
by Joachim Backes
Hi all,
i'm trying to configure my samsung laser printer ml-1660
as an (usb) duplex printer, but tis will not succeed anymore.
I'm using the Cinnamon desktop.
Neither the Cinnamon system settings menu entry nor the
system-config-printer (using obviously the splix pckg) command will
achieve this.
All system upgrades are installed.
Each advice would be welcome.

disabling nouveau
by Amadeus WM
My goal is to install nvidia cuda for some machine learning on a new Lenovo Thinkpad P52S laptop
running Fedora 30. The laptop comes with both an integrated intel card and an nvidia quadro P500 card
(I think this is called Optimus). I want to use the intel card for display and the nvidia exclusively
for machine learning.
I've followed various tutorials and blogs on the web, most notably
the rpmfusion howto: https://rpmfusion.org/Howto/NVIDIA
and a recent fedora magazine article: https://fedoramagazine.org/install-nvidia-gpu/
The latter says (in the comments) that there is no need to disable nouveau but I had to do that in
the past every time I installed the nvidia drivers, so I'm trying to do that now as well.
So I did the following:
1. Installed the nvidia rpms:
dnf install xorg-x11-drv-nvidia akmod-nvidia
which installed the following + dependencies:
[root@thinkpad ~]# rpm -qa | grep -i nvidia
xorg-x11-drv-nvidia-430.40-1.fc30.x86_64
nvidia-settings-430.40-1.fc30.x86_64
xorg-x11-drv-nvidia-libs-430.40-1.fc30.x86_64
akmod-nvidia-430.40-1.fc30.x86_64
xorg-x11-drv-nvidia-cuda-libs-430.40-1.fc30.x86_64
xorg-x11-drv-nvidia-kmodsrc-430.40-1.fc30.x86_64
kmod-nvidia-5.2.11-200.fc30.x86_64-430.40-1.fc30.x86_64
2. The dnf install command modified the boot options, to blacklist nouveau:
[root@thinkpad ~]# cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvidia-drm.modeset=1 resume=UUID=d1406222-e963-4043-a6f9-10c784752ed8 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
3. I read that is not enough though, as if nouveau is in the initram disk it will still do modeset = 1,
so I blacklisted it in modprobe.d and created a new initram disk:
[root@thinkpad ~]# cat /etc/modprobe.d/blacklist_nouveau.conf
blacklist nouveau
options nouveau modeset=0
# backup nouveau initram disk
[root@thinkpad boot]# cp initramfs-5.2.11-200.fc30.x86_64.img initramfs-5.2.11-200.fc30.x86_64_nouveau.img
# create new one:
[root@thinkpad boot]# dracut --force
Now
[root@thinkpad boot]# lsinitrd initramfs-5.2.11-200.fc30.x86_64.img | grep -i nouveau
-rw-r--r-- 1 root root 44 Feb 14 2019 etc/modprobe.d/blacklist_nouveau.conf
drwxr-xr-x 2 root root 0 Feb 14 2019 usr/lib/modules/5.2.11-200.fc30.x86_64/kernel/drivers/gpu/drm/nouveau
-rw-r--r-- 1 root root 636252 Feb 14 2019 usr/lib/modules/5.2.11-200.fc30.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko.xz
so it picked up the blacklist_nouveau.conf file.
4. set runlevel 3
systemctl set-default multi-user.target
5. I'm running Xorg, not Wayland:
[root@thinkpad ~]# pidof xinit
1351
[root@thinkpad ~]# pidof Xwayland
[root@thinkpad ~]#
6. Reboot. Even before starting X, I still get nouveau:
[root@thinkpad ~]# lsmod | grep nouveau
nouveau 2265088 0
mxm_wmi 16384 1 nouveau
ttm 118784 1 nouveau
i2c_algo_bit 16384 2 i915,nouveau
drm_kms_helper 225280 2 i915,nouveau
drm 495616 8 drm_kms_helper,i915,ttm,nouveau
wmi 36864 4 intel_wmi_thunderbolt,wmi_bmof,mxm_wmi,nouveau
video 49152 3 thinkpad_acpi,i915,nouveau
I can, however modprobe -r nouveau and things seem OK.
But what do I do to have it not load on boot? When this happened in the past, as a last resort,
I removed the appropriate rpms, but now the nouveau driver seems to be part of the kernel-modules
package:
[root@thinkpad ~]# rpm -qf /usr/lib/modules/5.2.11-200.fc30.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko.xz kernel-modules-5.2.11-200.fc30.x86_64
Any help on this, anyone? Thanks!

Hi All,
I have a flash drive with about four partitions on is.
Lets call it /dev/sdc.
Can I tar sdc or am I stuck with tarring the partitions?
Any drawback to this?

General protection fault involving flash
by Andre Robatino
The Citi.com credit card website allows generating virtual card numbers, but unfortunately they're using flash in that part of the site. When I try to use it in F30, on one particular machine (it's hardware-specific), in GNOME (it doesn't happen in MATE), the Firefox tab crashes and I get a general protection fault, for example
[88812.835817] traps: Web Content[2532] general protection fault ip:7f94ee0d0adb sp:7ffedd6a3140 error:0 in libX11.so.6.3.0[7f94ee0aa000+8e000]
Since flash is involved, it's not clear whether this is the fault of Fedora or flash. This has been happening for around half a year, so flash has been updated several times. It also happened with F29. Anyone know how to narrow down where the issue is?

Adding a UEFI boot disk to Grub
by Patrick O'Callaghan
I have an old-style MBR Grub configuration for F30. Converting the
system to UEFI seems like a hassle and doesn't provide an obvious
benefit for now (maybe next time I do a full install I'll go for it).
However I also run Windows 10 in a KVM/QEMU virtual machine. This has
its own dedicated drive and uses UEFI (OVMF). My BIOS supports UEFI and
I've managed to dual-boot a few times by fiddling with the BIOS
settings, but switching back and forth is clunky and error-prone, and
Windows always wants to "fix" itself before working.
My question is: how can I add this as an option to my Grub
configuration to enable dual-boot directly from the Grub menu (i.e.
running on metal, not a VM)? In other words, BIOS boots using MBR,
invokes Grub, which then (optionally) invokes UEFI to boot Windows. Or
is this not possible?

Has anyone tried Fedora on an RPi 4 (arm 8 architecture)? Does it work? How about RPi3?
