#175742 — Black screen after exiting X

Hi all Debian user.

After logging out X (I have Openbox as window manager) with Ctrl-alt-Backspace
(or also mouse right-clicking), tty1 is completely obscured and then I have to
do Alt-F2 (so going to tty2) and Alt-F1 and then I see tty1.  In Google I found
many similar problems but of no help to me.  Any suggestions?

Thanks,

Rodolfo

Please show the output of the following commands to document the issue better.

inxi -rG
dpkg -l openbox\* | grep -E "^ii|^ri"
uname -a

Are there any errors in the Xorg log file? The errors can be
identified by lines starting with EE. The log file can be in either
~/.local/share/xorg/Xorg.0.log or /var/log/Xorg.0.log.

Thanks. From https://nouveau.freedesktop.org/wiki/CodeNames/ , I see
that your codename is supported by the nouveau driver.

There is a new version of openbox 3.6.1-4 which addressed a dependency
issue between openbox-kde-session and plasma-workspace
(http://metadata.ftp-master.debian.org/changelogs/main/o/openbox/openbox_3.6.1-4_changelog).
If you are using KDE as your desktop environment you can try upgrading
to it and see if it helps. Otherwise, that may not help much.

It is not readily obvious (to me) if these errors are related to your
particular issue.

My guess is that there is some sort of incompatibility between the
kernel, graphics driver and window manager? Try to reproduce the
problem by using a different window manager such as metacity. If it
works then report a bug against openbox. If it does not, report the
bug against xserver-xorg-video-nouveau ?

thanks

I wonder if this problem's root could be related to this?:
https://bugs.freedesktop.org/show_bug.cgi?id=90572
startx exits to black screen

Cannot replicate here on Stretch running TDE on somewhat newer yet old GeForce:
Graphics:  Card: NVIDIA NV11 [GeForce2 MX/MX 400]
            Display Server: X.org 1.19.0 drivers: modesetting (unloaded: vesa)

Note use of modesetting rather than nouveau. Maybe purging
xserver-xorg-video-nouveau is worth a try?

The problem remains also with another window manager: icewm, as suggested by
Kamaraju, and also after `aptitude purge xserver-xorg-video-nouveau' as
suggested by Felix.  Thanks to both.  I have no idea of how to fix it.

Might well be the case.

As a troubleshooting attempt yes, but I would not recommend the
modesetting driver on such ancient hardware.  Using glamor[1] is not
going to work well, if at all.

Cheers,
       Sven
