I upgraded from F25 to F26 yesterday and ever since have been seeing the
system frequently become totally unresponsive.
It seems to be quite random and can only be resolved by hitting the reset
button to reboot.
On other occasions it doesn't quite die but starting anything takes several
minutes rather than seconds.
Thunderbird and dnf are examples but sometimes there is just no response to
key strokes or clicks.
The only clue that I have seen is that top often shows very high wait I/O
levels and swap space is sometimes (but not always) low.
Nothing has changed in the system workload or configuration.
This is a production machine so any help will be very welcome.
Cheers and thanks,

I have a (maybe stupid) question : I have installed BackupPC , but I can
not launche the application.
I also can not find the app listed in Applications.
So where can I find the app and start the program BackupPC ?

I'm pushing a change to the Fedora Rawhide kernel to enable the new
med_power_with_dipm sata link powermanagement policy by default on
mobile Intel chipsets (Laptops, NuCs, etc.).
The good news about this change is that on laptops using a sata disk
it will typically save about 1W - 1.5W of power when the laptop is idle.
The bad news is that the min_power policy is known to cause data corruption
with some disks (has been reported with older sandisk ssds and some crucial
ssds). The new med_power_with_dipm sata lpm policy mirrors the default
Windows IRST lpm settings, so it should be safe to use, but the proof is
in the pudding.
I've done a blog post a while back asking users to test
this: https://hansdegoede.livejournal.com/18412.html and here is a list
of successfully tested systens + disks:
So far no problems have been reported but if you're running rawhide now
would be a good time to make sure your backups are in order before
upgrading to the next rawhide kernel.
TL;DR: The next rawhide kernel build contains SATA changes which _may_
cause disk corruption, they shouldn't, but please check your backups
Anyone ever run into this? And how to fix it?
This is a fresh install of F27. I tried to build a program called MakeMKV.

I completed my installation of solid-state drives and, of course, a new
installation of F27.
And now: what happened to my system configuration tools? How do I start
and stop services?
My biggest problem is Samba. I can't see any Windows computers on my
network, and they can't see me. (I can, however, see a network printer.
That, I configured in the System Settings app.)
This relates also to another thread I started, namely "where are my
system configuration tools." This problem comes after a "clean install"
of F27. My old system-config-samba applet is gone--dnf can't find it to
install. And I don't see any launcher for NetworkManager or whatever I'm
supposed to use.
Right now, the Fedora system can't see any Windows computer on my
network--can't find it even with a direct address input (and I wouldn't
know how to send one.) And the Windows boxes can't see the Fedora
system, either--I type "\\[hostname]" and get a message saying "Windows
can't access [that host]."
I've already edited the files /etc/hostname and /etc/hosts to reflect my
choice of hostname. I replaced "localdomain" with "home," in keeping
with the Windows domain.
How can I check that the services smb, nmb, and winbind are even running?
If you have followed my threads about:
SMB failing with F27
system hanging and requring repeated restarts,
then you've seen people suggest replacing my 1 TB HDD with an SSD. I
acquired a 1 TB SSD and then tried to clone the HDD to the SSD. The
clone /failed/. Reason: the disk is already showing some bad sectors.
The outputs of satactl and fsck make that undeniably clear.
On the advice of a professional installer, I have since acquired an
additional SSD (capacity 120 GB) and am now acquiring a mounting bracket
and some power and SATA data cables. I also downloaded the F27 KDE
Plasma 5 Spin as an ".iso" image.
My plan is to install F27 "clean" on the two SSD's, mounting the 120 GB
SSD at root ("/") and the 1 TB SSD at /home. I must then migrate my
data, browser cookies (Google Chrome, Firefox), e-mail
accounts/saved/messages/other settings (Thunderbird), and documents,
pictures, music, videos, and various downloads from the HDD to the SSD.
This machine has 8 GB of memory on board.
I now ask the community for some suggestions.
First, for partitioning:
1. Should I even try to accept /automatic/ partitioning when the
installer gets to that point?
2. Is 120 GB large enough for the information on the other directories
3. Should I create a separate /boot partition on the smaller SSD, and if
so, how large should I make it?
4. How large should the swap partition be, and where should I put it?
(That is, on the 120 GB or the 1 TB drive)?
5. In general, should I place a partition for anything other than /home
on the 1 TB SSD?
Now, as regards data migration: I have three user accounts to migrate,
plus another directory on /home called "lost and found."
1. Should I even try to migrate "lost and found," and if so, how?
2. I have at least two choices for migrating data and settings from the
various user accounts--three for some of them.
a. Connect the HDD to the SATA bus /after/ installing F27, and then
force-copying everything out of each /home directory to its
corresponding directory on the new configuration. (What command(s) would
you recommend using, and with what options/switches/etc.?)
b. Connect a large external HDD through a USB interface, transfer
all the data to it before modifying the hardware, then re-transfer it to
the system after installing the SSD's and F27.
c. Migrate the data to its "temporary refuge" over a Samba network
(possibly do-able for at least one account, and that's the biggest
account) and then re-migrate to the new system?
Which choice would you recommend?
3. Is it worth migrating every single hidden file or folder? Or should I
select only those folders that I know contain customization, account, or
similar settings, plus my saved documents/pictures/music/videos, and
Thanks in advance.
I have Fedora 26 on laptop. I have configured dhcp (client) on both
ethernet and wifi (for work and home).
Later in different environment I've configured second ethernet profile
manually. I want let it configured for future use in that environment but
now when I connect at work to ethernet I have to switch profile on ethernet
connection from manual profile to dhcp profile.
Is it way how to set priority on network profiles or set one profile
default? I couldn't find it in documentation.

I have existing systems with un-encrypted disks.
I have tried unsuccessfully to encrypt them using LUKS.
Has anyone out there been able to encrypt an existing system (after the
fact, so to speak)?

I have just upgraded my system to Fedora-27, which has caused Evolution
to upgrade to 3.26.3 (3.26.3-1.fc27). Evolution now has a "To Do"
pane, which I don't want, since I use another program for calendar and
How can I remove the "To Do" pane?
Thanks - jon
