Nautilus search bar slow
by D. Hugh Redelmeier 08 Aug '18

08 Aug '18

(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 08 Aug '18

08 Aug '18

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-guest-…) 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: top - 07:13:02 up 12:49, 1 user, load average: 1.10, 1.84, 1.76 Tasks: 272 total, 1 running, 204 sleeping, 0 stopped, 0 zombie %Cpu0 : 4.7 us, 2.7 sy, 0.0 ni, 91.6 id, 0.0 wa, 0.7 hi, 0.3 si, 0.0 st %Cpu1 : 3.0 us, 4.4 sy, 0.0 ni, 92.6 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu2 : 4.3 us, 4.6 sy, 0.0 ni, 90.4 id, 0.0 wa, 0.3 hi, 0.3 si, 0.0 st %Cpu3 : 3.3 us, 5.0 sy, 0.0 ni, 91.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem : 16144924 total, 272940 free, 5217992 used, 10653992 buff/cache KiB Swap: 8224764 total, 8087004 free, 137760 used. 10409752 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 27942 ericp 20 0 3886324 2.130g 26340 S 28.7 13.8 27:26.31 qemu-system-x86 Reading other items online I used perf to see what is going on: $ sudo perf kvm --host stat live Analyze events for all VMs, all VCPUs: VM-EXIT Samples Samples% Time% Min Time Max Time Avg time IO_INSTRUCTION 493 56.93% 67.91% 2.91us 99913.26us 4255.31us ( +- 17.70% ) APIC_ACCESS 237 27.37% 7.71% 0.56us 99775.52us 1004.83us ( +- 51.23% ) HLT 106 12.24% 23.89% 0.59us 99841.70us 6961.72us ( +- 22.82% ) EXTERNAL_INTERRUPT 19 2.19% 0.00% 1.52us 5.56us 2.62us ( +- 9.42% ) EPT_MISCONFIG 6 0.69% 0.49% 28.66us 14837.17us 2506.17us ( +- 98.41% ) PENDING_INTERRUPT 3 0.35% 0.00% 0.74us 4.78us 2.91us ( +- 40.38% ) TPR_BELOW_THRESHOLD 2 0.23% 0.00% 4.21us 4.28us 4.24us ( +- 0.84% ) Total Samples:866, Total events handled time:3089057.95us. 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.

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.

SSH private keys?
by Jeffrey Ross 08 Aug '18

08 Aug '18

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 08 Aug '18

08 Aug '18

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, -T

Kernel 4.17.11 suspend seems to work
by Robert Moskowitz 07 Aug '18

07 Aug '18

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': start running ordered scripts...

I will report back on how things go. But we may be through the worst of this.
