Well, I use the nVidia drivers packaged by rpmfusion. The nVidia drivers don't use
the /dev/fb0 device.
Have a look in /var/log/Xorg.0.log for error (EE) messages.

With these high resolution panels, there is a problem with the size of
tools: for instance, I have a resolution of 1280x1024 and it is
sometimes difficult to catch the sliders of darktable tools, I fear that
it will be almost impossible to catch them with a higher resolution.
Once the devellopers will separate the display of the photos from the
tools to manipulate them (like in gimp), I would like to have the tools
on a screen with a reasonable resolution and the photos on another
screen with a higher resolution. But I am wondering if this possible
because, in that case, I need to be able to move the mouse from a screen
to another....

Re: Data backup- (udev problem)
by Angelo Moreschini
I understand what you say Francis, perhaps you are right, and I'll try your
suggestion.
But first of all I would like fix the basic problem (that the service
doesn't correctly).
All the tray that I can do before to solve this, could be affected from
this "original sin"...
It is not so much material finding for :
*"automount[1214]: setautomntent: lookup(sss): setautomntent: No such file
or directory"*
and I, also, am not able to understand exactly the meaning of this message.

Fedora vs. Meltdown & Spectre
by Jonathan Ryshpan
What do people know about Fedora vs. the Meltdown and Spectre bugs?
And should I enable "site isolation" in my browsers?

Feature Request for long links
by Beartooth
Firefox, along with few other browsers, has one valuable feature
that should spread. If you copy a *long* link (like, say, three to five
lines long in an email) into its address bar, it will eliminate the
spaces that come from line ends, and go to the site.
With most other browsers, you have to proofread the pasted URL,
finding and removing the gaps. Irritating, and a waste of time.
No doubt the code to fix those links is internal to Firefox, and
one would have to beg umpteen developers each to adopt it. But need it be?
Could Fedora maybe go into the code, say between any browser and
the networking code that tells the computer to send a link, and insert
something to clean the link before acting on it?
This would be a great boon, especially those of us who surf with
arthritic eyeballs and trifocal fingers.

Data backup- (udev problem)
by Angelo Moreschini
hi,
in order to backing up of the data , I wrote a script that uses the rsync
command.
This script have to be launched manually, and the data are saved on a USB
Hard Disk, which (obviously) must be mounted.
The mounting of the partitions for the back up on the USB HD is made
permantly at boot of the computer (the name of the backup-partitions is
wrote in the file / etc / fstab) :
UUID=376214F24CC07CE0 /media/BKx_data-personal ntfs defaults 0 0
UUID=479F99A324FF4D1D /media/BKx_programming ntfs defaults 0 0
UUID=EA8266EA8266BB29 /media/BKx_data-common ntfs defaults 0 0
This script works fine.
However, this solution for backing up the data is problematic, because *I
always receive messages with the request of access to the partitions ** of
the “backup-partitions”** by "nautilus"* - every time that I use the "find"
command.
I can consider that this problem is connected with the *permanent *
*mounting* of the partitions on the HD-USB (on the file /etc/fstab).
To avoid these problems I actually removed the permanent mounting of the
partitions by registering them on the file fstab and now I'm looking for an
alternative solution for the back up the data.
I think this solution can go in the following directions:
-
mounting the partitions (commanded by the script) before executing the
rsync command and unmounting them immediately afterwards.
-
alternatively, giving appropriate orders to the “udev feature” about the
backup partitions (I think this is possible to do, but I do not know how to
do it).
I would like to have some suggestions and advice about it.
Regards

How to get rid of VGACON error
by Dave B(Y)
Good afternoon!
I managed by various means to get my Fedora 26 to run KDE, but it
appears that all is not well...
i) during login, I get
[drm] VGACON disable radeon kernel modesetting (2 times) &
[drm] cannot get speed from usb address (approx)
ii) the system then comes up with the drawing of a river bank & asks for
my password
iii) system then comes up with a KDE Plasma screen, which it then
changes to a different size & then
iv) comes up with a more-or-less KDE start page.
I've had an amount of Trouble to get KDE running (the only live DVD I
have is running Gnome which I prefer not to use) & I'm no longer sure of
what real system I'm running.
I've tried taking the "nomodeset" out of /etc/grub, but that doesn't
appear to do the trick & I haven't been able to find anything else...
Updates are done OK, but it appears that a number of applications are
not listed in the launcher.
Can anyone help me????
Thanks all
Dave

how to recover from a failed system-upgrade
by Eyal Lebedinsky
First: this is an upgrade of a USB system and I have an image of f26 before the
upgrade to f27 and I will redo it in full. So no disaster, yet I want to understand
how the upgrade process recovers from such a failure (if at all).
I followed the usual process
# dnf update (and such)
# dnf system-upgrade download --releasever=27
# dnf system-upgrade reboot
but due to an oversight I turned off the power to the laptop (where the USB was
installed) so overnight it shut down.
This morning I tried to restart it. A reboot brought up a f26 kernel (though the
desktop background looked like f27). dnf thinks this is still a f26 system.
I tried
# dnf system-upgrade reboot
which started an upgrade, though with less packages listed. However, when the main
Upgrade/Install phase ended the post scripts were ran only for the recently listed
packages.
On a reboot I still was on f26, sort of, but some packages claimed to be installed
twice (e.g. dnf lists both f26 and f27).
Trying
# dnf system-upgrade download --releasever=27
failed saying some critical packages (e.g. 'dnf') will be removed.
What is the correct way to complete the upgrade? (I kept an image of the failure).
TIA

mounting a USB HD with autofs
by Angelo Moreschini
Hi,
only a simple (and maybe stupid) question ...
To use autofs for the automatic mounting of partitions existing on USB HD
(that is permanently connected to the computer), it is also mandatory to
install NFS ?
Thank you
