Blank Screen: KDE?

trashbird1240 · 12-15-2006, 09:25 PM

Howdy Y'all,

I've just installed Slackware 11.0 on my station at work and I'm getting a blank screen when I leave KDE. This has happened in three distinct situations: 1) In Slax (testing things out, trying to probe the monitor settings), I chose "logout" from the regular KDE menu; 2) after getting KDE from "startx" I again chose the regular "End this session" and got a blank screen, then 3) while in runlevel 3, I typed "kdm" and the screen went blank.

From other posts on here, I've figured out that I should just go to the next virtual terminal and log in again, but what causes this and how can I stop it from happening again?

BTW, in SLAX, the HorizSync was set to 85 Hz -- is that way out of range for a standard CRT? It seems high to me. I therefore hesitated to change xorg.conf.

Thanks,
Joel

Now, I've gotten kdm to start by running init 4, changing the default runlevel to 4 and commenting out the sections in rc.4 for the other display managers.

I've also edited the agetty lines in /etc/inittab as follows:

Code:

# These are the standard console login getties in multiuser mode:
c1:12345:respawn:/sbin/agetty 38400 tty1 linux
c2:12345:respawn:/sbin/agetty 38400 tty2 linux
c3:12345:respawn:/sbin/agetty 38400 tty3 linux
c4:12345:respawn:/sbin/agetty 38400 tty4 linux
c5:1235:respawn:/sbin/agetty 38400 tty5 linux
c6:1235:respawn:/sbin/agetty 38400 tty6 linux

Now, I boot into X (xfce to be exact), however when I exit any window manager, I still get a blank screen. I mean no screen output whatsoever.

The other thing is that I can't switch virtual terminals without losing the X server: i.e., if I press CTL-ALT-F2, I get another terminal login, then I hit CTL-ALT-F1 and I get the original login from before KDM started, but no X session. Where did it go?

Thanks,
Joel

The X server is running on tty7.

Before you edited the /etc/inittab file, the only virtual console would have been on tty6 for runlevel 4. Pat placed some comments in the inittab about this.

tty6 appears for runlevel 4:

Code:

c6:12345:respawn:/sbin/agetty 38400 tty6 linux

that makes sense, however should I be able to get back to it by pressing CTL-ALT-F7? (Because I can't

)

What I want is to get back to the display manager when I log out -- then shut down from there...should I just replace the original inittab?

Thanks,
Joel

Please let me know what I'm missing here: on other systems (e.g., my home system PCLinuxOS) in runlevel 4, when I exit KDE or any other window manager, I get KDM back offering me another login. Now I get a blank screen.

Here's the current /etc/inittab:

Code:

# Runlevel 4 used to be for an X window only system, until we discovered

# happens to X.

# End of /etc/inittab

Is the problem referred to in the note about throwing init into a loop the cause of my problem?

xorgconfig was the answer. Most people think love is the answer. However, in this case running a livecd and getting the settings from its xorg.conf was the answer.

Thanks,
