F25 Wayland on Optimus-enabled laptops
by Link Dupont
Two headline features of Fedora 25 are:
- Wayland by default
- Initial support for PRIME offload rendering for NVIDIA Optimus
laptops
My laptop has a dual GPU setup (Skylake + GTX 970), but I can't seem to
start a Wayland session at all. GDM even runs using Xorg, and the
"GNOME" session logs in using Xorg.
I checked my initramfs, but it includes the drm module, as well as both
kernel modules: nouveau.ko and i915.ko. From a console session, I can
start weston (weston-launch), but I can't start gnome-shell (dbus-run-
session -- gnome-shell --display-server --wayland). It errors with:
mutter-WARNING **: Can't initialize KMS backend: could not find drm kms
device.
The Wayland session worked in F24, so I'm guessing this is because of
the dual-GPU support enabled in F25. Should these two features be
mutually exclusive? Should I expect wayland *or* GPU render offloading?

process not disappearing from proc tbl..
by bruce
Hey guys..
Maybe too much food over the weekend.. Maybe brain cells are fried!
Created a basic/simple 5 line php test, It runs so chown/chmod are ok.
However, when I then run it as a background process, and check the
procTBL, the PID is there.. the process never leaves, unless I
manually kill it.. so... what have I forgotten.. I know.. the homer
simpson (doh!!) is going to be painful on this one..
my test php
------------------------------
#!/usr/bin/php
<?php
sleep(5);
print "running child_test \n";
exit();
?>
-----------------------------
running from the cmd line..
/cloud_nfs/child_test.php << runs fine, and not in procTBL after running..
trying to background from the cmd line..
/cloud_nfs/child_test.php & << never goes from procTBL unless
manually killed
/cloud_nfs/child_test.php 2>&1 & << never goes from procTBL unless
manually killed
So.. what did I screw up to run in background, and be removed from procTBL..
Thanks...
(be nice!!)

Continuing dnf weirdness
by Ian Pilcher
Can anyone explain this output?
http://pastebin.com/1xtjpB5s
I.e. why is dnf complaining about broken dependencies in
libreoffice-gtk2 and libreoffice-x11 when neither package is installed
or required by any of the updates being installed?

Is ldconfig doing this to me?
by Tom Horsley
For testing my hack to fix this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1395366
I renamed libepoxy.so.0.0.0 to libepoxy.so.0.0.0.orig
and put my own hacked version of libepoxy.so.0.0.0 in
the /lib64 directory in place of the orig.
Things worked for a while, then started failing again,
and now I notice that I have these symlinks:
tomh> ls -l /lib64/libepoxy*
lrwxrwxrwx 1 root root 17 Feb 4 2016 /lib64/libepoxy.so -> libepoxy.so.0.0.0*
lrwxrwxrwx 1 root root 22 Nov 21 10:03 /lib64/libepoxy.so.0 -> libepoxy.so.0.0.0.orig*
-rwxr-xr-x 1 root root 4588616 Nov 16 09:05 /lib64/libepoxy.so.0.0.0*
-rwxr-xr-x. 1 root root 1031200 Feb 4 2016 /lib64/libepoxy.so.0.0.0.orig*
So somehow the renamed file got linked back in to libepoxy.so.0.
My current theory is that maybe updating something completely different
ran ldconfig, and ldconfig rewrote the symlink. Does that sound
believable?
Maybe I need to move the orig file to some place other than
the /lib64 directory...

SELinux forces Fedora 25 upgrade into a reboot loop
by Sam Varshavchik
With selinux set to enforcing, my system-upgrade to 25 failed to start,
resulting in a reboot loop. I fished the following out of journalctl:
Nov 25 09:51:55 thinkpenguin.email-scan.com audit[1]: AVC avc: denied
{ open } for pid=1 comm="systemd" path="/var/lib/dnf/system-upgrade/.dnf-
system-upgrade" dev="dm-1" ino=1181602 scontext=system_u:system_r:init_t:s0
I had to drop to an emergency shell, and set selinux to permissive, in order
for the upgrade to do its thing.
Wondering if all upgrades with selinux enabled are broken, or just something
with this particular laptop. This doesn't look like a system-specific
failure to me, but if all upgrades with enforcing selinux blow up like this,
I would've expected a lot of noise in here, by now… More details in bug
1398696.

1TB disk, Nvidia GT 730/2GB.
Any reason F25 won't run on it? Other comments? Thanks.

Fedora 25 upgrade woes
by Denis Leroy
Hi List,
So I updated both my Fedora laptops from 24 to 25, resulting in both
booting into black screens with no login dialogs and no way of going
into a console or looking at logs.
Both systems are very different. One is a Lenovo, built-in Intel
graphics support and XFCE, the other is a Dell with a AMD Firepro M5100
graphics card running Cinnamon. Yet the result is the same. I assumed
Wayland is at fault here, however I noticed both systems work fine if I
boot with an older kernel:
kernel-4.8.6-300.fc25.x86_64 : works
kernel-4.8.8-300.fc25.x86_64 : nope
I had some trouble finding further info on this looking at various
forums and mailing lists, hence my message here. Any insight appreciated.

Middle Button Emulation -
by Bob Goodwin
I'm having troubled setting middle
button emulation in a new Fedora25
Workstation/XFCE installation. first I
added:
Section "InputClass"
Identifier "middle button
emulation class"
MatchIsPointer "on"
Option "Emulate3Buttons" "on"
Driver "evdev"
EndSection
to
/usr/share/X11/xorg.conf.d/10-evdev.conf
as I have done in the past. then my
notes led me to "xinput" but I can't
make that work, dunno the right command ...
I find it hard to work without this
feature, especially when configuring a
new install so it is one of the first
things I fix!
What am I doing wrong?
Bob
