Fan/sleep/hibernation issues on Dell Optiplex 780 usff fedora 22
by Matt Morgan
I have F22 on my son's Optiplex 780 ultra-small form factor. We seem to
have a variety of (maybe related) power management issues.
First, the fan often goes full-speed and starts making lots of noise.
Usually this is when the computer is actually doing more work, like running
Minecraft. Sometimes it happens when watching Youtube videos. Since these
are the two main things he does with the computer, it pretty much always
happens eventually.
Second, when this happens, and he then suspends the computer, the fan stays
on during suspend. It never quiets down. So I don't think the computer is
suspending properly.
Third, if I hibernate the computer, the fan shuts off, but the computer
actually shuts down--when he returns from hibernation, he has to log in to
a new session, his apps have all shut down, etc.
I used to use this computer (several years ago--it was probably F16, maybe
18) and I don't recall these issues, so I believe they must be fixable.
I tried installing TLP, not expecting much from it on a desktop, but
figuring it wouldn't hurt, and it didn't appear to change anything.
Any advice about where to start with this?
Thanks,
Matt

intel graphics driver fails to detect resolution
by Neal Becker
It seems if I plug in an external projector, using displayport with a vga
adapter, I can only get the resolution choice detected if I reboot.
Using kde/settings/display+monitor, the resolution is unavailable, unless I
reboot.
Any suggestion?

Fedora 23 log out automatically when login session left idle
by Jon Ingason
I newly upgraded one of my machine from F22 to F23 (Gnome) and got
following problem:
I start the machine and login. Open a terminal and do what I need to do
( update, ... etc). Then I left it idle for awhile. The screen locks.
Later after couple of minutes I tray to unlock it and if the idle time
is short nearly always I succeed to log in. Otherwise I get the login
menu and can select user to login. The problem it that when I have typed
in the password I come again to the login menu. I can switch to one of
the VT (virtual terminal) and login there, but if I try to switch back
either nothing happens or I get login menu but can't login.
I have search for this but has not found exact same problem. There is a
reported bug which describe similar problem:
https://bugzilla.redhat.com/show_bug.cgi?id=1266587
But any workaround given there didn't help.
My questions are:
- Have someone else seen this?
- How to troubleshoot?
- Do I open new bug report?

dnf install hangs waiting for process to finish
by David Aldrich
Hi
I am running Fedora 23 and am trying to install a package:
$ sudo -E dnf install moserial
Waiting for process with pid 1862 to finish.
This message never clears. ps does not list pid 1862. A reboot does not clear the problem.
How can I fix this please?
Best regards

IPv6 and NetworkManager
by Gordon Messmer
On most of the networks where I have hosts, the Ethernet interface has
an inet6 address with a 64 bit netmask and flags "scope global
noprefixroute dynamic."
On a Comcast Business network, though, my hosts have one inet6 address
with a 64 bit netmask and the same flags, plus another inet6 address
with a 128 bit netmask and flags "scope global dynamic."
Testing shows that these hosts use the address with the 128 bit netmask
by default as the source address for outbound connections.
I'm a little confused about the details here. Why are my hosts getting
multiple addresses with different prefixes?

Screen Blacking out Reliably After 15 Seconds Inactivity
by Tim Evans
F23: Linux harrier 4.4.7-300.fc23.x86_64 running on a Lenovo T530 with
Intel graphics:
lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core
processor Graphics Controller (rev 09)
xorg-x11-server-Xwayland-1.18.3-1.fc23.x86_64
Screen is blacking out reliably after 15 second of inactivity. Touching
the mousepad lights it back up, but often with a different app on screen.
Does not occur in Windows 10, so would not seem to be hardware-related.
Presumably, this is an X thing.
Anyone else seeing anything like this?

F23 dracut can't find disk
by CLOSE Dave
I have five machines which were fresh-installed with F23 back in
February and all have been booted successfully a few times since. Today,
booting of all of them fails in exactly the same way: dracut says it
can't find the disk filesystems. The kernel boots as it should, and of
course that comes from the disk, but then dracut comes along and says it
can't find any of the filesystems. Not the root or home filesystems
which are on LVM or the boot filesystem on a primary disk partition.
Everything on the disk is ok. I've checked by booting Anaconda from a
thumb drive and mounting manually. Anaconda troubleshooting mode says it
can't find the filesystems either ("you have no Linux partitions"), but
running vgchange -ay and a few mounts gets a proper chroot image.
There must be something that is causing both dracut and Anaconda to fail
to find the filesystems. I've tried following the instructions on
<https://fedoraproject.org/wiki/How_to_debug_Dracut_problems>, but that
isn't helping:
dracut:/# parted /dev/sda -s p
sh: parted: command not found
dracut:/# lvm vgscan
File descriptor 98 (/dev/console) leaked on lvm invocation. Parent PID
2679: sh
File descriptor 99 (/dev/console) leaked on lvm invocation. Parent PID
2679: sh
Reading all physical volumes. This may take a while...
dracut:/# lvm vgchange -ay
File descriptor 98 (/dev/console) leaked on lvm invocation. Parent PID
2679: sh
File descriptor 99 (/dev/console) leaked on lvm invocation. Parent PID
2679: sh
dracut:/# blkid
dracut:/#
Note that when booted from the thumb drive, vgchange finds the LVM
volumes just fine.
