Strange mouse issue in VirtualBox
by andrea
Hi
I occasionally have this strange mouse issue in VirtualBox.
Running an update version of Fedora 25 with GNOME and wayland. (64 bit)
Most recent VirtualBox 5.1.22
Guest Windows 10 with Guest Additions Installed.
Sometimes the mouse partially stops working and the only way to reset it I've found is to power off
the guest.
When I say partially I mean
1) mouse pointer still moves
3) it can be used to trigger the GNOME task switcher (top left corner)
4) no other control responds to clicks
As soon as the Guest stops, everything starts working again.
Keyboard still works and this is what I use to gracefully shut down the guest.
Somehow the mouse click event is trapped by Virtual Box and cannot be used.
I know it makes little sense, but this is my best description at the moment.

post-mortem: f24 boot fails; need help.
by William
Good morning,
The "f24 boot fails; need help" problem set me back a week. I'm still
catching up. I seriously believe it would be foolish for me to just
forget it. I should for the benefit of others try to get at the real
cause and possible prevention.
A few hours before the failure, I received and looked at an e-mail that
I'm almost certain was at least a spoof, and possibly malicious. I know
it contained html and links. I did *** not ***
click any of the links. I looked at it, and deleted it. It was viewed
in Thunderbird only. The message's "From" ended with "yahoo.com". My
question: It is highly improbable that that message had anything to do
with the boot failure. Am I correct?
Also a few hours before the failure, I did some web browsing using
Firefox with NoScript and uBlock Origin. As best as I recall, the
"riskiest" sites that I visited were finance.yahoo.com (and a few of its
sub-pages, I clicked no ads, no ad links) and indeed.com (possibly and a
posting or two). My question: It is highly improbable that my web
browsing had anything to do with the boot failure. Am I correct?
thanks,
Bill.

Fw: Systemd keeps trying to re-open an already active LUKS volume
by stan
Begin forwarded message:
I forwarded this to test since F26 is still not released, and they are
deciding whether to release this week. You are much more likely to get
an answer to your question there.

Subject: Systemd keeps trying to re-open an already active LUKS volume
Hi,
I need a piece of advice concerning an encrypted root partition on
Fedora 26. I'm running a custom manual setup created using dnf.
Further context:
* The installation procedure is outlined in this tread -- and quite
likely irrelevant to this question anyway:
https://lists.fedorahosted.org/archives/list/users@lists.fedoraproject.or...
* The disk layout is described in this comment:
https://bugzilla.redhat.com/show_bug.cgi?id=1297188#c2
Unlike Fedora 23 and 24, both of which booted just fine, Fedora 26 has
two glitches related to my encrypted LUKS root partition:
1. Dracut fails to automatically add the crypt module. It doesn't seem
to care about LUKS-related settings in /etc/default/grub and/or about
the fact that the system runs off an encrypted volume. I had to
manually add add_dracutmodules+="crypt" into /etc/dracut.conf, or else
I wouldn't get a password prompt on boot and the early systemd would
freeze waiting for the root partition to appear. It works normally with
add_dracutmodules+="crypt".
2. Possibly as a consequence of (1), systemd doesn't realize that the
root partition has been already activated and luksOpen'ed at boot time
and keeps trying to unlock it over and over. The consoles are spammed
by messages like this one, basically on every sudo invocation: Password
entry required for 'Please enter passphrase for disk cryptprdell-luks
(plainprdell)!' (PID 5492). Please enter password with the
systemd-tty-ask-password-agent tool!
Of course I tried to run the systemd-tty-ask-password-agent tool and
type in the password. But then systemctl --failed showed a failure in
systemd-cryptsetup(a)plainprdell.service, the auto-generated unit for the
LUKS volume. Presumably, journalctl revealed that the error message had
been "Failed to activate: Device or resource busy". Well, that's indeed
what happens when you try to open a LUKS volume that's already opened.
If I don't use systemd-tty-ask-password-agent at all, systemctl status
permanently shows "starting" and never reaches "running", because of
the LUKS volume it thinks it needs to activate. (I tried systemctl
disable, but nope, that had no effect.)
This appears to have something in common with an ancient bug from 2013:
https://bugzilla.redhat.com/show_bug.cgi?id=924581
Has anything changed (1) in the way Dracut finds out whether the crypt
module is needed (which worked at least up to Fedora 24) or (2) in the
way systemd generates its automatic units for encrypted volumes?
Something must have changed, but I have no idea what it is and how to
get the old behavior back. :-/
My /etc/default/grub and /etc/crypttab are attached. The current kernel
version is 4.11.0-2.fc26.x86_64.
Cheers,
Andrej

nfs problem
by Eyal Lebedinsky
I asked on AskFedora and got no response. Hoping this list is more active.
https://ask.fedoraproject.org/en/question/104010/nfs-showing-bad-data-f24/
I have a f24 workstation (nfs client). It is updated regularly.
The server is f19, so no updates there.
A problem started in the last few weeks. When I examine a file on the server it
looks OK. The file is updated every minute (collecting some stats) and 'tail' shows
the added lines as they arrive.
Examining the same file from the workstation is initially OK, but then, as the file
grows, I get binary zeroes at the end of the file. The same with tail, less, vi, etc.
The amount of zeroes seems to be the size of the extra data appended to the file.
'ls' shows the actual (full) size of the file. It looks like the utilities see the
correct size but bad data is delivered at the tail.
After a few minutes the full data is showing but then, as the file grows, again I get
zeroes for a few minutes.
Where do I look next?
TIA

hdmi monitor blanks when starting some apps
by DJ Delorie
I have multiple monitors on my system, one of which is HDMI (the rest
are DP or DVI). It's not the main monitor. When I start some apps
(esp games), the HDMI monitor blanks for a few seconds until the app's
window comes up (not full screen).
Is this a normal thing? Can it be prevented?

dependencies for kdm and gdm
by Rick Leir
Hi all
It seems that Fedora 26 allowed me to have KDM and LightDM installed
without gdm, gnome-shell, and mutter.
I had a crash while attempting to login using LightDM:
# journalctl -e
#2
0x00007feb273ed783 gtk_css_static_style_compute_value (libgtk-3.so.0)
#3
0x00007feb273d900c _gtk_css_lookup_resolve (libgtk-3.so.0)

#8
0x00007feb25bbf4b8 g_object_new_internal (libgobject-2.0.so.0)
Many neurons were lost trying to track the cause down, but then the fix was:
# yum install gdm

sudo su
by Peter Gueckel
I opened a second tab in konsole and immediately ran sudo su to
obtain a prompt as root. I ran a program and then I forgot to
exit and just closed the tab. Am I still root somewhere? Or did
closing the tab do the same thing as a proper exit?

Moderator approval?
by wwp
Hello there,
sorry to disturb w/ list management issues.. I've been tried to post
here but my message is waiting for moderator approval (since
2017-05-19). Nothing scary, but I wonder if it's because of its
contents.. There was a text attachment, I tried to sent it w/ the text
inserted in body instead, no luck. Is there really a moderator or am I
blacklisted in some way for an obscure reason? (I could post a reply to
another thread)
Regards,

Fedora command for motherboard clock condition (from: f24 boot fails;
need help).
by William
Good afternoon,
In the "f24 boot fails; need help" topic, a log file extract had these 2
lines:
1533 [ 4.022605] coyote systemd-fsck[428]: /dev/sda6: Superblock last
mount time is in the future.
1534 [ 4.022745] coyote systemd-fsck[428]: (by less than a day, probably
due to the hardware clock being incorrectly set)
One person noted
"The time problem suggests that the little pancake battery on the MB
that maintains the clock might be out of juice. I think these are 2032
style for PCs. It would be a good idea to replace it."
I responded
"I didn't know workstations nowadays had batteries. When the system is
back on its feet, I'll try to check that. It was bought in 2013."
I knew that the older motherboards had batteries. But I thought the
newer ones used something like flash (or other persistent) memory. It
did not occur to me that booting might want the date/time before the
boot process reached the point of being able to access the internet.
Two people corrected me. Someone else in the discussion said it well:
I sit corrected!
Fedora seems to have a huge number of commands. Does Fedora have a
command to report the condition of a full-sized tower motherboard
battery? If yes, what is that command?
thanks,
Bill.
