If you're asking how to use xscreensaver specifically (e.g., instead of

you want; take a look at the /usr/bin/xflock4 script for reference.)


Yes, that was indeed my question, thanks for the pointer!



Weird.  I have no idea what's going on there.  I have a VirtualBox VM
with Testing installed (VBoxVGA graphics controller), and the display
looks just fine for me.


The desktop has a Ryzen G processor, G meaning it comes with its own 
embedded GPU. It ran fine until before my holidays (and a bunch of 
updates), so far I've ruled out HW (other OS works fine), kernel version 
(happens with last known working version and also current kernel in 
testing) and desktop environment (happens with KDE and xfce4, lxqt has 
even worse graphic corruption issues), still have to rollback xserver 
and related stuff to check that.



Andrea.

Yeah, in 4.14 it's back in the Power Manager settings (System tab).  Or
at least, that's where the control is to enable locking.

If you're asking how to use xscreensaver specifically (e.g., instead of
Xfce's own locker (new in 4.14)), you can specify a particular locker
using the Xfce settings editor.  (Set /general/LockCommand to whatever
you want; take a look at the /usr/bin/xflock4 script for reference.)

For Xfce4 4.12, it's on the Advanced tab of the Session and Startup
settings.


Sorry for the delay, Mike: I had a busy schedule and opted for using a 
"safe" kernel on the laptop until I had more time to experiment.


I have xfce4 4.14 but I don't see anything interesting in that menu, see 
screenshot. This and the fact xfce is giving me crap [1] also on the 
desktop makes me feel like trying to switch environment altogether :D


Thanks for the assistance, though.

Andrea.

[1] image is fine until the login screen in X, after login it is an odd 
shade of green, mostly after resume but right now it happened on a fresh 
boot as well. System responds fine via ssh but chvt 1 does not fix it, I 
need to reboot. So far, I noticed that clearing ~/.config/xfce4 right 
after reboot and before logging in will give me a working display.

Hello, Christopher.



If this is the same problem I had (and discussed prior on this list),
there is a bug in light-locker that seems to cause this behavior
randomly even without hibernation.  Consider switching from light-locker
to xscreensaver; this resolved the problem for me.


Thing is, I never ever have any problem if I lock the screen but do not 
suspend, though. Anyhow, how do I get xfce to use xscreensaver as locking when 
suspending?

Killing light-locker gets me absolutely nowhere when it happens, I had 
already tried it :(



Andrea.

If it resolves the problem for you as well then I would hesitate to say
immediately that it's a kernel bug, even if the kernel version is
somehow related to the problem.
