Nautilus search bar slow
by D. Hugh Redelmeier
(I understand that Nautilus has been renamed "Gnome Files". But ps(1)
calls it nautilus, and so does the manpage, so I will too.)
I (on Fedora 28) use Nautilus once in a while. There is a handy feature
that if you start typing a filename, it will do some kind of search for
that filename. Very, very slowly.
What I have wanted and expected is a filter of the filenames in the
directory being shown. That should be fast. I don't know what I'm
getting, but in the end it seems to be such a filter.
The trouble is that the search takes several minutes. How could that
be?
Impatiently, I poked at it with strace and gdb. But only a little.
It seems to be in a poll command, waiting for something. I would
guess that that something is tracker. Who knows what tracker is
doing?
Gnome is so stripped-down that there doesn't seem to be a way of
configuring Nautilus from Nautilus. Gnome Tweaks doesn't offer
Nautilus customization. Nautilus Help offers nothing. Is there a way
of configuring Nautilus to just do a simple directory filter?
(I have found no "help" in any Nautilus menu. This seems like a
design mistake. In desperation, I tried the manpage. The manpage is
almost useless but it tells me to press F1 for help. I'm NOT a fan of
function keys and go years without intentionally striking one.)
Is there a good way to figure out why tracker is so slow?
Is there a good way to speed up tracker? There is no manpage for
tracker so I don't know much about it. Gnome Help has nothing about
Tracker.

gnome-boxes, high cpu when guest is idle
by Eric Phetteplace
Hello,
Using Boxes, I installed a Windows 10 guest. I installed the spice drivers from spice-space.org/download (https://www.spice-space.org/download/windows/spice-guest-tools/spice-gues...)
and things look good.
However, when the guest is idle, cpu is 0-4% the host process is significantly higher (28.7% for example below). I'm looking for advice on how to figure out what the problem is. The only thing I did so far is switch the disk bus from ide to virtio, and that didn't help.
I have an XPS 13 with plenty of ram and SSD disk space - i5 processor, running Fedora 28, 4.17.7-200.fc28.x86_64
Here's some output from top:

Reading other items online I used perf to see what is going on:
$ sudo perf kvm --host stat live

Lots of IO and APIC.
I was hoping the virtio bus change would take care of the high IO_INSTRUCTIONs, but it didn't.
I changed the windows powercfg to be "high performance," but that didn't reduce the APIC calls.
Here's another perf:
$ sudo perf stat -e 'kvm:*' -a -- sleep 1

Lots of fpu ?!?!? Lots of userspace exit. Lots of userspace, and looking at the top, the processors are doing an equal amount of usr and sys. I figure something is constantly doing system calls, causing lots of context switching.
I did "ps -Alf" to get the command line it creates. Hopefully this helps. I can provide the boxes config file if that's easier.

SSH private keys?
by Jeffrey Ross
At one point Fedora had something (keyring?) that would allow me to
unlock my SSH private keys and it would keep the unlocked key available
so I could ssh without having to unlock my key every time. I typically
run a simple "terminal" window and then "ssh <hostname>" since my key is
not retained unlocked I'm prompted for a password.
Fast forward to today, the system had been reinstalled (new hardware,
new disks, etc) and I no longer have that ability. I'm currently runn
Fedora 28 and the desktop is "Gnome", I'm sure it is just a matter of
installing/configuring/running the correct application.... but which one?
Thanks, Jeff

Gimp Panorama: What control points?
by ToddAndMargo
Hi All,
I am following:
https://listoffreeware.com/best-free-panorama-software-windows/
I get to the point:
Click on Set/Edit/View Control Points. Another window opens
up. Here you have to add Control points. To add Control
points, go to the images and select control points using
selection tool. Control points are common points that
are overlapping in both the images to be stitched.
I do get the pop up. But how do I add selection points? If
I click on something in one of the images, it is just whatever
doodle tool Gimp is set on and nothing ever appears in
the pop up box. Clicking a similar point in the next drawing
also does nothing. I have tried the square box selection
tool rom the list of doodle tools, but does nothing exept draw
a box around things.
The pop up box does not activate any special tool! AAAAA HHH !!!!!
What am I missing?
Many thanks,

Kernel 4.17.11 suspend seems to work
by Robert Moskowitz
I just upgraded to the new kernel. I will say that I believe that even
kernel 4.17.7 was good.
I have everything running and suspend works. The first suspend resulted
in that double suspend, but since then I have been good. The messages at
the time of the 'failed' suspend were:
Aug 7 11:41:02 lx121e nm-dispatcher[1976]: req:5 'connectivity-change':

After logging back in before the 2nd suspend there is the message:

msg='unit=fprintd comm="systemd" exe="/usr/lib/systemd/systemd"
hostname=? addr=? terminal=? res=success'
I do not anticipate another suspend until Friday afternoon. I will
report back on how things go.
But we may be through the worst of this.

gawk/getline
by Patrick Dupre
Hello,
This is a bit on the side, but the behavior of getline in gawk is a bit
strange.
getline $0
returns 0 when EOF.
but
getline "myfile.txt"
never returns 0
like if there in no EOF
What am I missing?
