Switching to Wayland on F27
by 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
SESSION UID 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.

problems to install NetBeans 8 on fedora 27
by Angelo Moreschini
Hi,
I installed many times NetBeans in a linux environment, without problems ...
But now I have problems to do it , after then I installed fedora 27.
When I try the installation, the output that I get is :
--------------------
[root@localhost Downloads]#* ./netbeans-8.2-linux.sh
<http://netbeans-8.2-linux.sh>*
Configuring the installer...
Searching for JVM on the system...
Extracting installation data...
*Running the installer wizard...*
*Can`t initialize UIRunning in headless mode*
*Exception: java.awt.HeadlessException thrown from the
UncaughtExceptionHandler in thread "main"*
--------------------
This is a problem about the java environment ?
it can be also a problem with the graphical environment of fedora ... (?)
I worked around many time without a result...
Can I have some help please ?
Thank you
regards

Thunderbird issue (OT).
by William Mattison
Good morning,
When I try to sign in to a (verizon) yahoo e-mail account via Thunderbird, it takes several seconds to get a response, then I often get this error message:
------
Thunderbird
The current operation on 'Inbox' did not succeed. The mail server for account
[my e-mail account] responded: [CLIENTBUG] SELECT Command is not valid in this
state.
------
I then have to exit Thunderbird, and sign in again to all the accounts I want to connect to. I usually have to do this 2-4 times before it finally downloads the folder structure and message headers successfully (though v-e-r-y slowly). I experience this problem randomly but frequently (almost daily) with all 6 of my (verizon) yahoo accounts. My incoming server is set to "imap.mail.yahoo.com:993"; my outgoing server is set to "smtp.mail.yahoo.com:465"; connection security is set to "SSL/TLS".
Yahoo e-mail does not work properly in my browser, so that's not a good work-around. I've checked both yahoo and Thunderbird on-line help; I get nothing really helpful, though I notice the problem is not unique to me.
What's the real cause of this problem, and what do I fix it?
Thank-you for your help.
Bill.

gthumb crash (after enabling vdpau?)
by 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.)
Trace/breakpoint trap (core dumped)
and /var/log/messages includes a trace:

I see that the gthumb package was updated in 2017, dnf.log says:
Aug 19 18:09:33 DEBUG ---> Package gthumb.x86_64 1:3.4.3-1.fc24 will be upgraded
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

What is target #1?
by Tom Horsley
I see fedora 28 schedule says release is tomorrow, then there is
another release next week for target #1. What on earth does that mean?
(I clicked on the link and the word "target" does not appear in
in the page it takes me to, so the meaning seems well disguised).

28?
by ToddAndMargo
Anyone know the latest rumor as to when 28 general release will hit?
I have two of my four running on 28 beta and I rather like it. Things
just keep getting better and better. Fedora is a beautiful example
of a Kaiser (constant improvement) OS.
I use to be on an RHEL clone. RHEL, by design, is an anti-Kaisen OS
and I almost went INSANE!

Sudo but no su -
by Bob Goodwin
.
I installed Virtual Manager in this Fedora 27 workstation system and
created afedora 28 beta installation and was surprised to find I
haveonly user bobg, no root account. Sometimes it's convenient to keep a
work space for root and I was unable to do that, could not do dnf
upgrade or groupinstall xfce unless I used sudo. Is that a virt-manager
feature or is it going to be normal for Fedora 28?
