freezing afer switching from graphical to console

freezing afer switching from graphical to console

[Michael Gruner]

Hi,

since 2.4.17 I have got a problem: trying to switch from graphical
screen to console or to stop my X-session my box freezes. The screen
gets black and nothing more happens. Pressing any keys or trying to
switch to another console the box does not do anything. Only o cold
restart brings the box up again.

Hardware is a MSI6126 with a 440bx chipset. The processor is a 400 MHZ
Celeron on a MS6905 ppga 370 to slot 1 cpu converter. In former times
there were 256MB RAM in there but I got a lot of segfaults during
compiling the kernel. So i removed 128MB and now compiling runs fine.
So I don't think it might be a hardware failure?!

Problems had be seen very often with kernel 2.4.18, now with 2.4.19-rc1
not as often as before. That means: it happens maybe 1 or 2 times a
week. The box is shutted down every day.

Are there any hints for solving this problem?

best regards,
 Michael

I don't have this problem on 2.4.18, but I did on 2.5 kernels.  On my 
box, it had something to do with the display manager (kdmh).  When I 
boot to runlevel 3 and run startx manually (without kdm) I have no 
virtual console problems.  That's my workaround for now.

I don't know what causes the problem.  If anyone else has an idea to 
share, that'd be great.

viel glueck,

Sorry, yes, that was a typo.  I meant kdm.

This only happens to me if I load the NVidia drivers if you are using
them that could be you
problem.

Hi, 

we have seen it, too. Seems to be graphics card dependend (ati ones are not 
effected, but nvidia cards are ) and what powersaving mode is enabled in the 
BIOS (Suspend for the Monitor causes a lock up when switching from X to the 
console, but when using VSync/empty screen (or something like this) all works 
fine).

I am also having this problem with an ATI r128 card and KDM. I found that by
setting:

TerminateServer=true

in the kdmrc file helped a lot.

Hi,

ok, did it as you say: in the BIOS I switched to Vsync/blank screen.
Let's see what happens.

BTW: My graphics card isn't a nvidia as many of you suggested but an ATI
Rage pro (what did you wrote Bernd? ;-) ).

Another interesting thing I got back in mind today was: one day my XMMS
played a mp3 song and I switched to console (oooops...you know what
happend) but the song kept on playing in a loop that was some
milliseconds until I powered the box off. I don't know what to think
about that.

best regards,
 michael

How bizzarre - I've never seen that
with the nvidia drivers - I gave away
an ATI card to a windoze user since
the ATI DRI would hard lock the box.

(I know, help is on the way, but I had
an immediate need!)

Since switching to a GeForce 2, there
have been no problems whatsoever.

When you say "that only happens" if
you "load the nvidia drivers", do you
mean to say that you only see that
freeze if you run X windows? Or, that
you see it only if you enable DRI?

Lots of things beside nvidia to blame,
if we are on a witchhunt....

I've seen the same thing on my ATI XPert@Play (Rage Pro chipset).  At 
  2.4.17, it was a risky proposition to switch between X and a text VC.
  It's better in 2.4.18, although not much (I believe.  I may be wrong).
  I have happend upon a situation a number of times where, when switching
  from X to a text VC, the machine "locks up", but CTRL-F7 (the X VC) will
  get me back to a working X login screen (KDM), at least for a while.  If
  I keep trying to switch to a text VC (which never works), it eventually
  fully locks up, to the point where I have to pull the plug, since the on
  switch is non-responsive.  If I tell it to shut down, it gets *most* of
  the way through before carping out and locking up fully.
I don't *believe* I've seen this in 2.5.x, although I may be wrong.

I am also using GeForce 2 currently I am using the nvidia drivers
that comes with X window. NOTE: they do _not_ support DRI. The only
drivers that support DRI are those that I supplied by NVidia (as far as
I know)

The freeze when switching from graphic mode to console has been around
for a while now look at:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0111.2/0237.html
and yes not everyone who complained had the nvidia drivers loaded.

Yes the could be other things that causes the hangs, but _I_ only
experience those hangs when _I_ use the nvidia drivers.I'm not on a
witch hunt, but when I can't reproduce the problem without the nvidia
drivers. I think it is logical to start suspecting that the problem is
caused by those drivers.
