Switching to Wayland on F27

[Digimer]

Hi all,

  I've updated my OS a few times now and it would appear that I am still
on Xorg of Fedora 27 workstation;

From:
https://docs.fedoraproject.org/f27/system-administrators-guide/Wayland.html


  0 digimer@pulsar:~$ loginctl
   SESSIONUID USER SEAT TTY
c2 42 gdm  seat0/dev/tty1
 3   1000 digimer  seat0/dev/tty2

2 sessions listed.
  0 digimer@pulsar:~$ loginctl show-session 3 -p Type
Type=x11


  That link doesn't say how to switch to Wayland, though. When I click
on the gear icon at the login screen, I only have "Gnome" and "Gnome
Classic" as options.

  Any hint on how to enable Wayland?

Thanks.

[Jeremy Tourville]

Thank you both for your replies.  I am new to learning directory server in the 
Linux world.  I have always used AD before and while I have a fair bit of Linux 
experience using DS has been a new experience for me.  I'll check through the 
logs and see what I can figure out.  Thanks for pointing me in the right 
direction!  :-)  More to follow.

If you are using NFSv4, remember that the first export is the *root*. 
That is, clients refer to filesystems relative to that export.  If your 
/etc/exports looks like this:


/home/export 192.168.1.0/255.255.255.0(ro)
/home/export/home  192.168.1.0/255.255.255.0(rw)

...then clients would mount "server:/home" not "server:/home/export/home".

I have a whacking great big huge Wacom drawing tablet (A3) sized, but
it is an older one.  I just plug it into the USB socket and the system
recognises it like some kind of track pad, and programs like GIMP let
me draw with it.  Didn't have to do anything more than plug it in.

You might want to google the particular model you're interested in
along with keywords like linux compatibility.  You may find that it
simply "just works."  This [1] suggests that support was on the way, a
while ago, albeit for a different flavour of Linux, maybe by now
someone's built a working package.  I haven't gone searching in depth
to see if there's any further development.  The developer [2] has a
blog.

Your other avenue is to look into how to make use of github projects,
in general, then see if you can try the one for this drawing tablet.

Glad it worked. Possibly a different DM might be easier to use for you.
You can change the DM quite easily, e.g.:

I should have also said that you could do something like:

# mkdir -p /home/nfsshares/whateverdir
# cp -a /home/whateverdir /home/nfsshares/whateverdir

OR

# mkdir -p /home/nfsshares
# mv /home/whateverdir /home/nfsshares

Then export /home/nfsshares/whateverdir by:

1. Edit /etc/exports and insert a line:

/home/nfsshares/whateverdir 192.168.1.0/24(rw,no_root_squash)

2. Re-export the modified /etc/exports via:

# exportfs -ra

3. Mount the export on a client:

# mount server:/home/nfsshares/whateverdir /local-mountpoint

Note that by doing this, you're exporting a subdirectory of /home and
thus have the entire 2.7TB available to the NFS client.

Make sense?

Server end:

# df -h /home/exports/home
Filesystem   Size  Used Avail Use% Mounted on

/dev/mapper/fedora-home  2.7T  4.8G  2.5T   1% /home

So that's where I want to put ,y nfs data.

I have a directory /home/exports/home/ where I put an empty file "xxxtest."

# ll /home/exports/home/
total 0
-rw-r--r--. 1 root root 0 Apr 18 11:05 xxxtest

Did:  # exportfs -r

Then:

# showmount -e box86
clnt_create: RPC: Unknown host

Uhm, that looks like "box86" either isn't in DNS or /etc/hosts so it
can't be resolved. If this is on the server, try "showmount -e" or
"showmount -e localhost".


Client end:

No access from the client -

bobg]# mount 192.168.1.86:/home/exports/home  /mnt/test
mount.nfs: access denied by server while mounting
192.168.1.86:/home/exports/home

What am I missing and/or doing wrong?

We don't know what your server's /etc/exports line that exports the
directory looks like, so there's no way to tell. The line should be
something like:

/home/exports/home 192.168.1.0/24(rw,no_root_squash)


From a subsequent mail in this thread it seems to me that Bob has the 
following in /etc/exports (using Rick's syntax above):


                /exports/home 192.168.1.0/24(rw,no_root_squash)

which seems to me to be providing network access to the exports/home 
directory on whatever device in the server is the "/" mount point.


If this is the case it seems to me that /etc/exports should have a 
specification like Rick's, assuming directory /home/exports/home exists 
on the server, and then the client should have the follow in /etc/fstab:


                192.168.1.86:/home/exports/home/ /mnt/test/        
nfs4    defaults    0 0


or am I missing something?


regards,

Steve




meaning that /home/exports/home is exported with read/write privileges
to all hosts on the 192.168.1.* network, and that if a client mounts it
as the root user, the root user ID is NOT squashed to the "anonymous"
user on the server. You could run

showmount -e 192.168.1.86

on the client to see what the server is exporting.

No, /etc/exports tells the NFS server which directories to export via
NFS. If you want to export /dev/fedora00/home, first find out where it's
mounted on your NFS server. You can do that by running "df -h" as root
on your NFS server. Example (again from my laptop):

[root@golem4 ~]# df -h
Filesystem Size  Used Avail Use% Mounted on
...
/dev/mapper/vg_golem4-lv_home  252G   49G  191G  21% /home

So /dev/mapper/vg_golem4-lv_home is mounted on /home. So, if I were
going to make my laptop an NFS server, I would add a line such as:

/home   192.168.1.0/24(rw,no_root_squash)

in my laptop's /etc/exports file. IMPORTANT: You export where the
filesystem is _mounted_--NOT the raw device (in this case, you export
"/home" and NOT "/dev/mapper/vg_golem4-lv_home").

Once that's done, I'd have to tell the NFS server daemon on my laptop
that I had made changes to the /etc/exports file by running the command:

[root@golem4 ~]# exportfs -ar

The NFS server daemon on my laptop would then refresh its list of what
it's supposed to export. To verify it, you could run a

showmount -e localhost

on the server to see what it thinks it's exporting, or

showmount -e 

on one of the NFS clients to show what the server is exporting. Note
that the showmount command only shows the export name and not what
the raw device is on the NFS server. In fact, the NFS server daemon on
the server (which is what's responding to the showmount queries) doesn't
even know what device holds the directory being exported. It only
understands directories.

Then you'd mount the export on the client. Using the above stuff, an NFS
client that wanted to use my exported "/home" directory and mount it at
"/nfs/home" would do something like:

[root@nfs-client]# mkdir -p /nfs/home
[root@nfs-client]# mount -t nfs :/home /nfs/home

where "" is either the hostname of the NFS server or its
IP address. The first command creates the mountpoint on the client if it
doesn't already exist, the second mounts the filesystem via NFS. If you
wanted to put that in your /etc/fstab ON THE CLIENT so it'd mount at
boot, you'd add a line such as:

:/home  /nfs/home nfs   defaults0 0

Again, where "" is either the hostname of the NFS server
or its IP address. Note that with that line in your /etc/fstab on the
client, you could mount the filesystem via a simple

[root@nfs-client]# mount /nfs/home

and the mount command would look for a line in /etc/fstab that matched
the filesystem specified, see that it's an NFS mount (via the "nfs"
filesystem type part of the entry or the fact that the device string
contained a ":/" sequence of characters which are unique to NFS volumes)
and invoke the proper command.

Remember, entries in /etc/exports ON THE SERVER tell the SERVER what
_directories_ to export to the clients--NOT the raw device containing
the filesystem.

I should have mentioned that I have tried unplugging the HDMI cable -
the only effect is that the A/V receiver recognizes the disconnect.
I.e., it goes from a black screen to the screen the receiver provides
when there is no connection.  So far the only thing I have found that
will "reset" the connection is to power-cycle the NUC.

Wacom Bamboo Slate and Fedora 27+

[Jeremy Eder]

I'm constantly drawing workflows/diagrams on a notepad...I like the freedom
of ink and paper.  I then manually convert the useful ones to google
draw/lucidcharts.  I stumbled on this
https://www.wacom.com/en-us/products/smartpads/bamboo-slate … and am
intrigued.

It looks like the way to get it running is:
https://github.com/tuhiproject/tuhi … but I wondered if anyone else has any
experience with them or similar (perhaps more stable) products like the
Wacom Intuos Pro?

By default, Fedora uses the LVM (logical volume manager) system to
partition the disks. It actually creates regular partitions as a raw
volumes (PVs or "physical volumes"). It then typically creates a VG
(volume group) that has that PVs in it. From there, it carves out
LVs (logical volumes). On my laptop, for example, I have these (among
others) from the "df -h" command:

/dev/mapper/vg_golem4-lv_root  426G  214G  208G  51% /
/dev/sda1  477M  206M  242M  46% /boot
/dev/mapper/vg_golem4-lv_home  252G   49G  191G  21% /home

You can see I have a /dev/sda1 partition that is used as my boot volume
(/boot). Note also that my / and /home filesystems are on LVM. To see
how that's set up:

When you look at that, you can see there's a VG (volume group) called
"vg_golem4". That volume group is split up into three logical volumes,
"lv_root", "lv_swap" and "lv_home" and you can see the /dev names
they're known by. You can also see at the bottom that the VG has a
single PV, /dev/sda2.

Now as far as your /etc/exports file goes, you can have as many lines in
it as you want. To wit (from an NFS server in our datacenter whose DNS
name is "nfssrv598-r1"):

[root@nfssrv598-r1 ~]# cat /etc/exports
# /etc/exports

Uhm, that looks like "box86" either isn't in DNS or /etc/hosts so it
can't be resolved. If this is on the server, try "showmount -e" or
"showmount -e localhost".

We don't know what your server's /etc/exports line that exports the
directory looks like, so there's no way to tell. The line should be
something like:

/home/exports/home 192.168.1.0/24(rw,no_root_squash)

meaning that /home/exports/home is exported with read/write privileges
to all hosts on the 192.168.1.* network, and that if a client mounts it
as the root user, the root user ID is NOT squashed to the "anonymous"
user on the server. You could run

showmount -e 192.168.1.86

on the client to see what the server is exporting.

Which display manager are you running? GDM, SDDM, LightDM? Each has
a different way of specifying which desktop to launch.

HOORAY! That last word did it. I clicked in the uttermost corners 
of the monitor (not just the box, which I had taken to be the login 
screen), and the third one (upper right) had a tiny icon which proved to 
be for exactly that. With my arthritic eyeballs and trifocal fingers, I 
might never've found it without help. Many, many thanks!

Re: troubles with lyluatex package in Fedora

[Federico Bruni]

I installed native TeX Live 2017 and now everything works fine.

As it works also in Debian 9 with TeX Live 2016, it looks like a 
problem in some texlive Fedora package. I saw a tiny difference in the 
version of some packages between Debian and Fedora, for example 
luaotfload module. See my comment here:

https://github.com/jperon/lyluatex/issues/180
https://lists.gnu.org/archive/html/lilypond-user/2018-03/msg00707.html

I tried lyluatex using TexLive 2016 in a Debian container and it 
works fine.
But for some reason it doesn't work on Fedora 27, which has also 
TexLive 2016. This was confirmed by another Fedora user (see above 
link to lilypond-user mailing list).


I also tried upgrading TexLive to 2017¹ (in a container I use for 
testing), but then found another problem:

https://lists.gnu.org/archive/html/lilypond-user/2018-03/msg00741.html

It looks like I need a more recent version of TexLive 2017, 
containing these critical luatex fixes committed in June:

http://git.preining.info/texlive/log/?h=branch2017

I'm Cc-ing spot, author of below copr repository.
I was about to try to update his .spec file, but I see that the 
latest release of TexLive 2017 is dated 24th of May, while it seems I 
need a later version.
Before investigating more, I'd like to know if someone is already 
working on it.


Thanks in advance!
