Advanced apology here at first -- even before I start -- for my
I installed a Password Manager and was using it for some days.
Now, can it be deinstalled? I have even forgot the name. I have set
Password for the account and all. But, every time I go to login, it
pushes up a window with two buttons 'OK' and 'Cancel'. I have to
cancel it every time.
I know nothing about the Manager, except only this that I got the name
from the Net and installed it on Fedora 30.
Can I be saved?
I've got a new machine with an nVidia card and an external 4K display.
For whatever reason selecting 4K in the graphical display resolution
tool causes the Nouveau driver to crash. After this I can no longer
log in because even after a reboot it tries to select 4K again.
How can I (from ssh) change the display resolution back to something

virt-builder quickly builds VMs from scratch
I've used CentOS 7 as a host for KVM guests for several years now. I'm using the CentOS Virtualization SIG's version of qemu specifically because I was anxious/curious to try making VMs with UEFI (OVMF). I also transitioned to using Virtio-SCSI a few years ago, so when I started experimenting with OVMF, I used Virtio-SCSI for the block devices, as usual. In that environment (more details below), everything Just Worked.
I'm now experimenting with using Fedora 30 to host guests using KVM. I have successfully create a guest using Q35/OVMF. I used a VirtIO-SCSI block device, as I've done on CentOS in the past. The guest (Fedora 30 Server) PXE network booted in UEFI mode, and correctly installed F30 Server to the block device, creating a UEFI System Partition and a GPT disk.
However, it wouldn't boot. I poked around, comparing the guest made on the F30 host to the guest made on the C7 host, pressing "F2" when the guest booted to get into OVMF's UI. It was there that I realized that OVMF didn't "see" the VirtIO-SCSI block device at all. It didn't list the entire drive it as a boot option, and it (obviously) didn't show the UEFI boot entry stored on its UEFI System Partition.
I switched the device to a VirtIO device, and it booted right up.
So, now I'm wondering if I've missed something. Should OVMF be able to recognize a VirtIO-SCSI block device on a Fedora 30 KVM host? Did something change between what I've been using on CentOS 7 and here to remove that? Or was I maybe just getting lucky on C7 all along, successfully doing something that shouldn't be working?
Below are some of the packages I have installed on my two VM hosts. The Fedora 30 host is very standard. The C7 host has packages from C7's virt SIG, so they're newer than the KVM offered in C7's base install. The base packages don't support Q35/OVMF at all. (Always made me wonder why RHEL 7 included OVMF, but no way to use it.)
I noticed that the guest created on CentOS is using this as the UEFI: /usr/share/OVMF/OVMF_CODE.secboot.fd but the one created on F30 used /usr/share/OVMF/OVMF_CODE.fd instead. I edited the VM to use OVMF_CODE.secboot.fd on the F30's VM, but it still didn't work (the disk was still not recognized when I used F2 to enter OVMF's interface).

Since I have >7 Fedora installations I setup a squid proxy server
specifically for the purpose of reducing my download data since many of the
same packages are going to get downloaded over and over again.
I seem to be getting some hits (still looking for a GOOD squid analyzer!)
but not as much as I would expect. I'm no regex expert but I tried to
update the regex to pick up delta RPMS as well and may have made a
Here's my modifications to the default squid conf file...

I have a DELL Precision Mobile 5530 with an NVidia card and the
proprietary drivers (if only I could use the non-proprietary ones)...
Since I switched to Fedora 30, it seems that USB-C power supply does not
work (the battery is not charging)... I was afraid of a harware problem,
when I noticed that when I resume after a suspend or a hibernate, the
standard power-plug also does not work either (it re-works after a full
restart of the computer).
So I now tend to believe, it is a software problem...
Has anyone encoutered this situation ?
Has anyone has clues on how to diagnose or correct the trouble ?
I know my kernel is tainted, but would be very grateful of any help tyo
solve the issue...
Thank's in advance for any help...
I have a small F29 Server VM (KVM/QEMU) which has not changed recently
and has worked consistently for several months. Now when I try to boot
it I get:
Requested operation is not valid: Setting different SELinux label on /home/poc/VM/vm-f29b.qcow2 which is already in use
I haven't touched any SElinux settings, though I do update my host F30
system on a daily basis so something may have changed.
The current context for that file is:
$ ls -lZ vm-f29b.qcow2
-rw-------. 1 qemu qemu system_u:object_r:svirt_image_t:s0:c467,c977 21478375424 Aug 11 11:14 vm-f29b.qcow2
Any thoughts on what I should look at?

Can someone point me to a good instruction for entering it? I simply
want to add two columns, E and G, and subtract F. I've done this before

My NFS problems continue. The hard drive was replaced, Fedora 30
installed and NFS is configured. I think the configuration is good, I
followed the instructions anyway.
Firewlld appears to be a new stumbling block and I don't know how to fix
it. I looked at the Firewalld GUI and there is nothing intuitive about
it. If I stop Firewlld, showmount displays the exports.
