I don't know what you mean by that.  I thought the nVidia drivers had VDPAU 
enabled
by default.

What do you get as the output of vpauinfo?  You may have to install it.

gthumb crash (after enabling vdpau?)

[Eyal Lebedinsky]

I recently replaced my graphics card (with NVIDIA GT 710).
A newer nvidia module was installed
kmod-nvidia-340xx-4.15.7-200 -> kmod-nvidia-390.42-1
I also enabled VDPAU which was incorrectly installed until now.

I now have a failure of 'gthumb':

$ gthumb -v

(gthumb:7097): Gdk-ERROR **: The program 'gthumb' received an X Window System 
error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 159 error_code 16 request_code 152 (DRI2) minor_code 1)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I see that the gthumb package was updated in 2017, dnf.log says:

Aug 19 18:09:33 DEBUG ---> Package gthumb.x86_64 1:3.4.5-1.fc26 will be 
an upgrade
The update was part of a f24->f26 upgrade. There is no later version of gthumb 
but I do see
version 3.6.0 in f27.

I also see that this gthumb version is one year old:
$ ls -l /usr/bin/gthumb
-rwxr-xr-x 1 root root 988384 Apr 20  2017 /usr/bin/gthumb

The gthumb package depends on the libvdpau package so I suspect some 
incompatibility.
Reinstalling both packages does not improve the situation.

Is gthumb still maintained? https://github.com/GNOME/gthumb suggests perusing
https://wiki.gnome.org/Apps/gthumb which is not present.

Still, too many packages are involved, not the least X/nvidia ones.

Is anyone else seeing this problem? I do not want to log a bug if this is the 
result
of my system long update history, but I do want to resolve this.

I have another f26 machine that has no problems but does not use vdpau (or 
nvidia card).

TIA

These processes are generally part of the evolution-data-server package
and despite the name are not limited to Evolution. They provide various
services such as calendars and alarms via d-bus to Gnome sessions. For
example evolution-alarm-notify is configured in /etc/xdg/autostart.

Whatever you currently have as the imap server for the mail account. 
Probably that address.



Then create an account in Evolution that connects to imap (not imaps) at 
"localhost".

You could just replace the hostname listed above with "localhost" and 
change it from imaps (or imap with ssl) to just imap with no ssl.

Dnfdragora Issues

[Stephen Morris]

Hi,

    I have encountered some issues with dnfdragora, one of which is 
fairly serious for me.


    If I use the search function to get a list of specific packages, it 
displays the details for the first package which is fine. If I then 
click on another package it does not show the details for the clicked 
package, I have to uncheck/recheck if it is installed or check/uncheck 
if it is not installed, to see the details. Having done this once 
clicking on packages in the search results displays the details 
correctly for the rest of the display of the search results. If I issue 
another search query the issue repeats itself. This issue occurs every 
time I use dnfdragora.


    The second issue which for me is a bit more serious, is that when I 
look at the steam related packages from the negativo17 repository, and 
attempt to look at the changelog to get the contact details for the 
maintainer, dnfdragora tells me the change details are missing, but if I 
do the same thing with yumex it shows the changelog details, so the 
changelog is actually there.


    Has anyone else encountered this issues and have a solution?

regards,

Steve

Try this:

This will tell you what the name of any service involved is, with -i

OT:Question on NVME disk direct access?

[Michael D. Setzer II]

I'm the maintainer of the G4L disk imaging project since 2004, and I use 
Fedora as the build platform. Currently using Fedora 27.

Have an issue from a user that has me baffled, so am hoping someone here 
might provide some guidance. 

The program boots a linux kernel, and basically uses dd to copy the 
disk/partitions thru a compression program and creates an image file on ftp 
server or local device.

I don't have any physical nvme disks, but using virtualbox I created a 4M 
disk, and 2 - 2M partitions within it. In testing that, the 4M disk compresses 
to 
a 30K file, and the 2M partitions compress to about 15K each. That is what is 
expected with cleared partitions.

The user though, with a real 256G disk doesn't seem to get any compression 
of the disk or partitions. Them resulting images are close to the same size as 
the disks or partitions??

He can mount the partitions and see the files, so there must be something 
going on that I don't see? 

Would think that accessing the /dev/nvme0n1 or partitions /dev/nvme0n1p1 
thru p5 would act the same as accessing /dev/sda or /dev/sdax partitions.

The images that are created pass the compression program test, so it is 
reading data, but in some form that doesn't compress much, and user has 
used a program to clear the unused space?

Thanks for your time, and any ideals.

What is the universal (world wide) understanding behind degaussing harddisks?

[Turritopsis Dohrnii Teo En Ming]

Good evening from Singapore!

The foremost question which I want to ask is, what is the universal
(world wide) understanding behind degaussing hard drives?

I work for No Secrets Agency (NSA) Pte Ltd (fictitious company name
used). My sales manager Edward Joseph Snowden (fictitious individual
name used) had *promised* our customer Leave Me in the Lurch (S) Pte
Ltd (fictitious company name used) that we would "DEGAUSS" their hard
disks after the PC replacement and data migration exercise for 15
trillion PCs (fictitious number used).

PC = Personal Computer, which includes desktops and laptops

Last Friday, I had already reflected to my sales manager Edward
Snowden that since we are definitely NOT going to wipe our customer's
data by using strong and powerful magnets (physical means), should I
send an email to the IT Administrator of our customer Lady Gaga
(fictitious individual name used) asking her which data sanitization
method (by software means) I should use? My sales manager Edward
Snowden had quickly deflected my concerns (that is, wanting to send an
email to our customer Lady Gaga asking her which data sanitization
method I should use).

I had brought up to the sales manager Edward Snowden a number of data
wiping methods by software means last Friday.

(1) Very very simple 1-pass data wiping, quickest

a. Using "sudo dd if=/dev/zero of=/dev/sda", overwriting harddisks
from beginning to end with zeroes, where /dev/sda refers to the 500 GB
harddisk, not /dev/loop0 and not /dev/sdb which refers to the bootable
live operating system on thumb drive

b. Using "sudo dd if=/dev/urandom of=/dev/sda", overwriting harddisks
from beginning to end with random data, where /dev/sda refers to the
500 GB harddisk, not /dev/loop0 and not /dev/sdb which refers to the
bootable live operating system on thumb drive

Any bootable Live CD/DVD/flash media could do it.

(2) 3-pass U.S. Government/Department of Defense (DoD) standard (DoD 5220.22-M)

Certified commercial software required

(3) 7-pass U.S. Government/Department of Defense (DoD) standard (DoD 5220.22-M)

Certified commercial software required

(4) 35-pass Gutmann method, slowest

Certified commercial software required

All these was last Friday. In the midst of our argument over the
cellular network "just now", my sales manager Edward Snowden tried to
cover up himself by suddenly and unexpectedly making an excuse that he
had told me last Friday I was supposed to wipe user data only, not the
operating system!

If he had wanted me to wipe user data and retain/keep the Windows
operating system, he should simply have told me to Reset the PC (for
Windows 10 only) or use a =secure File Shredder=! For Windows 7, you
can still wipe user data and preserve the operating system by using
the Recovery Partition. On Lenovo desktops, press and hold F11 when
Windows 7 is starting and reset to factory defaults.

I had advised my sales manager Edward Snowden not to use BIG WORDS
like "degaussing the harddisk" and market to the customer using these
big words. Any person who sees the word "degauss" would have
understood it to mean sanitize *ALL* data on the harddisk straight
away and without question.

Please refer to Figure 1. Exhibit A below for the "degaussing"
instructions communicated to me by my sales manager Edward Snowden.
Please click the link below.

Thank you very much.

ldapmodify is best because it enforces schema syntax and value
validation.  But if you edit dse.ldif the server must be stopped first. 
As the dse.ldif is rewritten by what's in memory at server shutdown.

You can try installing the gcc package from rawhide (or probably better 
the F28 repository, currently at beta), but the usual problem with doing 
this sort of thing is that you find you have to update a lot of dependent 
packages as well, and it ends up simpler and probably safer just to update 
the whole system to the later version.


In the case of gcc you might be okay to do it, as I don't think there are 
many dependent packages and they look fairly self-contained but it may 
depend on what else is installed.


There are also alternatives you could try, for example if it is a package 
you could use mock to try building it under F28, or you could build your 
software an F28 docker container.

Well, Pod is a mark-up format. So no.

But with tools like Pod::Html (https://metacpan.org/pod/Pod::Html) and

Never edit that file directly. Always use ldapmodify.

Have you looked at Pandoc (http://pandoc.org/)? It will definitely
read HTML and write groff (the format that man pages use).

I'd recommend using Pandoc to convert your HTML to Markdown and using
that as your source - generating other formats from that.

You might need to do quite a lot of manual clean-up of the Markdown
files though. But you'd only need to do it once.

Not specificly recommending POD, it was just a good syntax for the 
time. Quite low in features, but in many cases that is a good thing.


I need to revisit this sometime myself, as I've got a project that 
will need man pages and fuller documentation as well.


Can POD generate an entire web site, with an automatically-generated 
table of contents?


Not really. Like I said, low in features.

The Python people seem to like restructuredtext a lot; there's a tool called 
sphinx for making whole sites from it, which seems liked.


https://www.libcxx.org is just one big Docbook document, with navigation 
footers. Doxygen generates the reference pages. Doxygen produces an XML file 
with an index of all the reference pages. I run a custom XSLT stylesheet to 
translate the index to URLs and entity references, which then gets included 
into the main, paginated tutorial, generates links directly to the reference 
pages.


I'm a big fan of good cross linking.

But my basic point is that authoring syntax for humans needs to be 
light weight so that the source looks a fair bit like ordinary 
prose. Tools can always be written to generate specific outputs.


The more it looks like ordinary prose, the less metadata exists that 
makes it possible to intelligently format it.


Sure, but a lot of prose doesn't need a great deal of special formatting.

I'm not sure we disagree very much here, except for my dislike of syntaxes with 
heaps of punctuation everywhere, and XML falls into that slot for me.
