Slackware64-current 1st April, 2010: Black screen on leaving KDE session
 

With the updates of today I hoped an annoying problem would be solved, but unfortunately, this is not the case.

The problem: I use runlevel 4 and KDM. Leaving a KDE session should throw me back to the KDM logon dialog. But instead I see a black screen, with a cursor prompt blinking in the top left corner. But no input is accepted, apparently, from keyboard or mouse. I cannot even switch to a terminal.

All I *can* do, is shutdown the machine, either remotely from another computer via an SSL login, or by pressing the power button of the computer.

Maybe this is still related with the recent NVIDIA incompatibilities with Xorg (Nouveau?). I have an NVIDIA 8600 GT graphics adapter, and I am using the 64-bit driver version 173.14.25. Within a session, everything is fine. But quitting a session causes the above problem. I hoped that this would be solved with the Xorg updates, but unfortunately they didn't help.

BTW, Nouveau is blacklisted in my /etc/modprobe.d/blacklist.conf.

Questions:
1. How do I fix this?
2. Does anybody else have the same problem, or am I the only one?

THANKS!

Hello :)

According to the nvidia website, your 8600 GT should be supported
by the newest drivers, which are 195.36.15. Maybe try this latest
version.

I'm running a 9500 GT and never had a black screen at logout,
but my local slackware mirror is still rsyncing, so I don't
have the latest update installed yet.

Greetings

Thanks, 195.36.15 did the trick. Actually, the reason for 'downgrading' were problems with the Xorg updates one month ago. 195.x just wouldn't work, here. Also, there was a problem with overheating, and NVIDIA decided to withdraw a version. Now it's an official release and it works just fine, again!
