Xfce Lock Screen Flashes Erratically {SOLVED}

[Alexzee]

After a little reading I'm not the only one complaining about XFCE flashing erratically.
It's a problem in Arch Linux and it's a problem on my Slackware 15 system.

Xfce lock screen flashes erratically

Did my weekly update on Sunday, with about 85 packages. I use xfce4-screensaver and lock my screen via xfce4-power-manager inactivity timeouts. After my system update and a reboot, the lock screen flashes and is very hard if not impossible to recover from. In several instances I’ve had to...

It's a problem on Arco Linux too-

I can't log in once the system shuts the monitor down. Moving the mouse wakes the system up however; the screen and XFCE DE flashes consistantly.
Trying CTRL + ALT + F1 does give me a tty but that flashes as well and attempting to log in to try to shut down can't be achieved.
So far all that works is to hold down CTRL + ALT + DEL to reboot:-

One of the suggestions in the first link is to remove xfce4-screensaver all together and use light-locker instead.
Light-locker is not in the Slackware.

Any suggestions on how to fix this issue would be greatly appreciated.

XFCE 4.18 has been released.

Download – Xfce

www.xfce.org

Compiling isn't my favorite thing and I'm not that good at it.

XFCE 4.18 is only available for Slackware current. I'm running stable so I will have to wait.

If I find another way I'll post it:-

The newest version of XFCE 4.18 was released and the build instructions are here:

xfce:building [Xfce Docs]

docs.xfce.org

Never had the chance to run Arch Linux or have time to learn the package management system.
Having said that, if your a Arch Linux user reading this and you have found a way to fix the lock screen from flashing erratically: do tell!-

After much thinking, I remembered that a Slackware 15 Current pkg can be rebuilt to be able to be installed on a Slackware 15 Stable installation. When time permits I'll look for the instructions and if I can fix it I'll share the experience.

Notice I said "if"--

The good news is Patrick Volkerding and his Slackware Team fixed the issue.
Performing the update/upgrade a few days ago fixed the XFCE log in from flashing.

I found the instructions on how to rebuild a Slackware pkg:

What I'd like to know is how to fix, rebuild, install newer version of pkg's and DE's and etc. broken pkgs on a Debian system too.

Did anyone with the XFCE log in flashing erratically fix it on their Arch Linux system?

Debian has a few "fix it" options in the package manager tools it uses such as apt, apt-get, dpkg, synaptic, aptitude. In apt for example, there are options "--fix-missing" and "--fix-broken". The dpkg command can reconfigure things if it's a configuration issue.

Debian package management is really a wonderland of tools to help the user use their systems as well as extract themselves from troubles. The apt tools include:

apt                           aptitude-changelog-parser
apt-cache                     aptitude-create-state-bundle
apt-cdrom                     aptitude-curses
apt-config                    aptitude-run-state-bundle
apt-extracttemplates          apt-key
apt-file                      apt-listbugs
apt-forktracer                apt-listchanges
apt-ftparchive                apt-mark
apt-get                       apt-show-versions
aptitude                      apt-sortpkgs

and the dpkg tools include:

dpkg                     dpkg-mergechangelogs
dpkg-architecture        dpkg-name
dpkg-buildflags          dpkg-parsechangelog
dpkg-buildpackage        dpkg-preconfigure
dpkg-checkbuilddeps      dpkg-query
dpkg-checkdeps           dpkg-realpath
dpkg-deb                 dpkg-reconfigure
dpkg-depcheck            dpkg-ruby
dpkg-distaddfile         dpkg-scanpackages
dpkg-divert              dpkg-scansources
dpkg-fsys-usrunmess      dpkg-shlibdeps
dpkg-genbuilddeps        dpkg-source
dpkg-genbuildinfo        dpkg-split
dpkg-genchanges          dpkg-statoverride
dpkg-gencontrol          dpkg-trigger
dpkg-gensymbols          dpkg-vendor
dpkg-maintscript-helper

The aptitude package manager has an ncurses display if one prefers that, and there's synaptic too. Both have their additional means of assistance.

One would not say that debian is undersupplied with package managment assistance.

On the building of deb packages, debian docs are pretty extensive on that one, but it's not something I've done recently enough to comment.

Whither slackware?

Thanks, osprey!
I'll cp that list tomorrow and put it in vi and save it in my home directory. I'd do it now but I've learned not to do things when I'm tired.

With Slackware the command's and the package management system is different and a little more in depth.
Ton's of documentation at slackware.com to help me:-
