Re: Backing up system
by gmspro
Hi,
http://www.sysresccd.org/Download
With the SystemRescueCd I backed up the /dev/sda6 partition in /mnt/backup/ naming "diskimage"
After backing up operation the file has the automatic extension like "diskimage.000".
Is this file ok to restore?
If I name it "diskimage.gz" then it is automatically renamed with this extension "diskimage.gz.000"
But here below
http://www.sysresccd.org/Screenshots
the file is name like this:
"diskimage.pimg"
Do I have to name with the .pimg extension during backup to restore correctly?
And how can I restore it?

Many thanks,

vncserver program disappered on FC32??
by Michael D. Setzer II
Have two machines running Fedora 32, and just noticed with the latest
update of tigervnc-server the vncserver is GONE?
Did a downgrade on both machines, and it is back and running just fine.
The one machine had rebooted, and therefor wasn't able to load the
server. The other machine still had the server running from before the
upgrade, so was able to vnc into it.
The file from the /usr/bin director was just no longer there. Tried a
reinstall, and still no file. Only the downgrade option restored it??
Not sure on how to report this. Didn't notice it until trying to vnc into
machine that had rebooted? The dnf whatprovides shows that the
program is included, so not sure what kind of error is in the latest
update??
Thanks and be Safe...

Dragora bollixed?
by Beartooth
I'm running F33 Mate, but I think I was also seeing the problem I'm
asking about under at least F32, and maybe also earlier.
Dragora has two icons that I can put on a panel. One of them is
supposed to be an updater. It works, afaict.
The other seems intended to do what it used to: permit me to
slice and dice lists of apps, and to install or remove them. On any new
install I used to use it heavily, eliminating apps I knew I'd never use,
and adding ones not present by default that I do use.
Both icons do only the check for updates. Have I damaged
something? Or is the exhaustive form deprecated?? If so, is there a
replacement?

Odd screen rotation misbehavior
by Matthew Saltzman
I have a Lenovo Yoga X1 (2nd gen) with Intel graphics, running GNOME
(fully up to date). Recently, the screen rotation lock control in the
system menu (drop-down in the upper right corner) disappeared and the
screen stopped auto-rotating. I had been running in Xorg mode because
certain Zoom features don't work under Wayland. At some point, I
switched to Wayland mode and the control reappeared and auto-rotation
started working. That worked for a while, but then the control
disappeared again. I switched back to Xorg mode and the control is
back.
Anyone have any idea what's going on and/or how I can get consistent
behavior?
Thanks for any hints.

mysterious/suspicious internet activity.
by home user
Fedora-32 home workstation; gnome.
In ksysguard, I've been noticing internet activity that I can't explain. This has been going on for weeks, and it's making me uncomfortable.
What I do:
1. After the system has been powered down overnight, I boot it up.
2. I sign in to a user account.
3. My .bash_profile sources my .bashrc, sets PATH, and launches xeyes. My .bashrc sources /etc/bashrc, sets PS1 and PATH, and defines aliases.
4. I launch ksysguard, then Spectacle.
5. I wait several seconds, then take a screen-capture of ksysguard's display.
To get a good sample, I did five screen-captures. Here are the google drive links to them:
"https://drive.google.com/file/d/1EdlSgKY0fJpU7r3nbstWA7G_2C93gOgO/view?us..."
"https://drive.google.com/file/d/1jfocTMRnwguRdDIchoBtsNYYwQZr647i/view?us..."
"https://drive.google.com/file/d/1Tx3kDEMbL_TCZZ-F0YOVOXSy2D9G3MAM/view?us..."
"https://drive.google.com/file/d/157KU27QtsJTZghyRgeuafYSnvxR85im4/view?us..."
"https://drive.google.com/file/d/1AyZDRvcKYHYypNSU6AF9Fh34rh_l3q2J/view?us..."
Notes:
* neither Thunderbird nor any other e-mail client nor Firefox nor any other browser had been launched since powering up.
* as far as I know, nothing else that uses the internet had been launched since powering up. actually, the only things I had running were xeyes, ksysguard, Spectacle, and (in the last screen-shot only) gnome terminal (which was idle).
* as far as I know, nothing is set to auto-update.
* as far as I know, nothing has telemetry permission enabled.
Yet there is persistent, continual (not continuous) internet activity in both directions. What is it? What on my system is communicating with what externally, and what is being communicated? Unauthorized updating? Unauthorized telemetry? Unauthorized distributed computing? Spyware? Crypto-currency mining?
This is way outside my knowledge and experience. I need good step-by-step instructions on this.
Thank-you in advance.
Bill.

Hibernate resume failed on kernel 5.9

systemd[1]: Finished Resume from hibernation using device
/dev/disk/by-uuid/03aef3ba-dca1-4cba-a3f5-36c5c0fe948e.
I don't even know how to reproduce this error.
It happens at spurious times, mostly when my system is shut down for a long
period of time, like two hours.
Should I file a bug? Or is this a problem with my system ?

Lost the UEFI boot info that my BIOS shows
by Fulko Hew
Something went wonkers with my system, and although I could try to reboot
it would get so far and then fall back into some kind of maintenance mode.
Rather than fight it at the time, I thought it was a good time
to ensure I have a good backup of my home filesystem.
So I booted a Live USB stick and performed my backup.
Now I wanted to go back and try to diagnose/fix my root filesystem issue.
Sadly, my BIOS no longer knows about the bootable entity on the HD,
and only shows me the Flash drive (even if it's not plugged in).
Any idea what happened to my HD boot info in my BIOS, or how to restore it?
PS. It is a Dell laptop.
TIA
