everything was working fine under knoppix 7.2

Why is that happening? What can I do to troubleshoot that problem?

Thank you,

knoppix 7.2 and 7.4.2 seem to have the same version of vlc

and I am using the same machine anyway. Could that possibly be a problem with the new kernel used? lbrtchx

OK, I think I have an idea why this is happening. It happens when you go "Suspend" (using the GUI) without going "# init 2" first on the command promt.

I have noticed also, after you re-awake your box, the text on the bottom of the "Logout LXDE 7.6 session?" gets mangled

Any ideas about what I should do to troubleshoot those seemingly Graphic-subsystem issues further?

[Albretch]

actually without using "init 2"

1) logout

2) suspend

seems to do it, but then you will have to recreact your working context anew.

I still think you should be able to just "suspend"

Let me know if you want for me to try something to debug that issue
