Restoring a QEMU snapshot
by Patrick O'Callaghan
I have a QEMU image snapshot:
$ sudo qemu-img info /var/lib/libvirt/images/Windows10.qcow2
file format: qcow2
virtual size: 20G (21474836480 bytes)
disk size: 196K
backing file: /home/poc/Win10/win10.qcow2
backing file format: qcow2
Format specific information:
lazy refcounts: true
refcount bits: 16
However when I try to restore the virtual disk I get:
$ sudo qemu-img snapshot -a /var/lib/libvirt/images/Windows10.qcow2 /home/poc/Win10/win10.qcow2
qemu-img: Could not apply snapshot '/var/lib/libvirt/images/Windows10.qcow2': -2 (No such file or directory)
I must be doing something obviously wrong, but can't see what it is.
Hints would be appreciated.

the latest of both.
dnf list installed | grep -e firefox -e flash-plugin
vmware-tray received an X Window System error
by Dominik Kucher
Is that a bug? i have installed today the update to 12.5.5
The program 'vmware-tray' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
(Details: serial 2374408 error_code 141 request_code 138 minor_code 7)
(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 --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
monitor restarting (from sleep) issue on F25, HP Envy
by Matt Morgan
I just bought an HP Envy and installed F25 over the weekend. I have a few
problems I did not have on the Dell XPS 13 it replaced. First, upon
resuming from sleep, my external monitor doesn't wake up. The monitor says
it's getting no input from the PC, and the Displays settings app doesn't
show a second monitor.
The only differences from before are
a) the XPS 13 had a mini-displayport, and this one is HDMI
b) this is a fresh install of F25, where the old computer was upgraded
probably from F22.
What can I do, any suggestions? Right now only rebooting seems to work.
F25: Desktop PC not booting without a screen
by Eigeldinger Simon
I am Simon and I am blind.
I tried to boot a Fedora Workstation 25 live USB without a screen attached to a desktop machine.
It seems the machine doesn't boot completely at least hanging while the desktop should come up.
On the arch wiki i read something about x server and its autoconfig mode where it detects the screen and if no screen is present it stops starting the desktop which makes the PC hang.
According to the wayland mailing list this also happens with wayland though wayland supports screenless booting. which needs to be specified in the wayland adapter for gnome.
Anyone maybe knows more about that?
I thought of using Fedora on a project i have in my mind. Having a small PC without a screen in the kitchen would be pretty interesting. navigation is done using a keyboard and knowing where we are is done using the orca screen reader and speakers.
Attaching a screen would be the last thing i want to do.

Weird crashes and slowdowns
by Susi Lehtola
I'm wondering if anyone else has noticed weird things happening on their
My Lenovo U31-70 has been misbehaving for a long long time under Fedora.
Firefox and/or X often slow to a crawl, and sometimes X even crashes.
I'm wondering if this is due to a buggy video driver.

arrow in the file/explorer window
Just noticed, in looking through the dialog for some dirs, I see a
curved arrow in some of the folder icons. This appears to indicate
previous versions of things like jre/jdk. Is this correct? Can't seem
to find anything in SO on this..
F25 - outragous memory consumption
by Fulko Hew
Running F25 I'm seeing (IMHO) some outrageous memory consumption
Here's what top showed (just before the system hung up completely).
ksmserver taking 13Gig of memory !
pulseaudio taking almost 4Gig !
No wonder my system hung.

f25 and ATI graphic cards
by François Patte
Does anyone know how to get rid of this:
[drm:atom_op_jump [radeon]] *ERROR* atombios stuck ......
[drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck....
and some other messages
Sometimes it takes ages before shutdown
I could see that many people have this problem since several years (not
only with fedora: debian, ubuntu.... also)
Is there a kernel option to add at boot time?
