I now know how to get to XFCE working again on F28 following attempts to test 
F29.

cp -au .../dot_config_2018_11_02_ja_backup_GTX2/dconf /home/ja/.config
cp -au .../dot_config_2018_11_02_ja_backup_GTX2/autostart/ /home/ja/.config
sometimes a reboot is required (still using very old syntax!)
shutdown -r now

diff -qr did the trick when finding these files/directories

However I have still not been able to use my account on F29 without freezing
and core dumps.

I think it is to do with "autostart" but I have no idea what.
After 15 to 20 years of using XFCE my current solution is

dnf groupinstall LXDE
which has caused no problems with my account - yet.

Aside/In addition
I have been getting core dumps associated with xfce on F28 for several weeks
but they have never made the machine unusable.
This was definitely not a hardware problem as they occurred on at least two 
machines.
dnf downgrade to xorg-x11-server-Xorg-1.19.5-1.fc28.x86_64
did not appear to solve this problem.
It was not possible to downgrade on F29 because of dependency problems.
I'm pretty convinced xfce has some significant bugs.

You could probably identify what files have changed using diff, by 
comparing the changed directory tree with the original one. For example


diff -q ~/.config ~/.config.original

It'll output which files are missing (from src and rest) and which files 
are different. It could still be a lot, but it might narrow things down. 
Afterwards you can remove the -q and see what those differences are.

Hmmm - Interesting

I have spent the whole day on this - being very concerned that
my F28 machine and/or Centos server account may become corrupt.

Tomorrow is another day!
Thanks

I've been having serious issues debugging programs built
on NFS filesystems. I can't point to a specific thing yet, but
I'm really suspicious of NFS at this point. (Same sort of debugging
same sort of programs, no problems under fedora 28).

Serious F29 Problem - For me!

2018-11-06 Thread ja
I have a fully working (Clean Installed) F29 test machine which
seems OK for some users (fred) who has a very small home directory.

User home directories are NFS mounted from a
Centos 7.5.1804 server

I am using lightdm & XFCE on both F28 & F29

I login to F29 as me (ja) and the display locks up continually,
the display can become smeared, applications freeze, ...,
it is totally unusable - core dumping maybe.

I login to XFCE as another user (fred) and su - ja and run applications
with no problems - evolution, google-chrome, pcmanfm, ...

I conclude that there is something in my ~/.config or ~/.cache
that F29 cannot handle during the login phase or shortly after.
There are 11323 files in ~/.config
and 5431 in ~/.cache

Worse still when I return to my F28 machine as ja then
problems are now present on that machine as well.
Presumably ~/.config (maybe ~/.cache) has been corrupted by F29.

I have to restore ~/.config (394MB) and once ~/.cache(532MB)
from a backup before I have a usable F28 machine again.
(and hence can send this email)

I have tried things such as "find ~/.config -amin -3" to find
changed files but nothing I have deleted/moved has helped.

I have used journalctl -f and top

I have seen xfce4-panel, xfsettingsd, xfdesktop seg fault
(libgdk-3)

At one stage I thought "setenforce 0" helped but now not convinced.

Has anyone else seen this problem or has some suggestion for
better ways of trouble shooting?

I am loathe to have to re-create all those settings in ~/.config

Struggling!
