No Konsole in X with kernel 2.6.7

zorolowski · 08-05-2004, 10:29 AM

Hello,

I installed kernel 2.6.7 on my Slackware10. Since this time I have no working konsole in X-windows. It doesn't matter, which window-manager I choose. A window opens, but I don't get a command-line. In gnome I got the message 'There was an error creating the child process for this terminal'.
All other programs are working fine. I had no problems with kernel 2.4.26.
Any ideas?

Greetings
Zorolowski

try reinstalling the latest video drivers for your card....hope that works

Did you compile the kernel yourself or install it as a package ? In both case did you try edit lilo config and put vga=normal in it (if it is a framebuffer console problem, but I doubt, it seems not)

It doesn't matter, what video driver is installed. I have a ati radeon 9600 and tried to resolve the problem with the generic X driver and the 3.9.0 from ati. It's always the same.
I compiled the kernel by myself. vga=normal is enabled.

Have you these feature enabled in /usr/src/linux/.config ?

CONFIG_UNIX98_PTYS=y
CONFIG_LEGACY_PTYS=y
CONFIG_LEGACY_PTY_COUNT=256

Thank you, Cedrik! Now it works!

I have the same problem (but on a debian system) with the kernel 2.6.12.2

I have
CONFIG_LEGACY_PTYS=y
CONFIG_LEGACY_PTY_COUNT=256

but I cant find the option
CONFIG_UNIX98_PTYS=y

with menuconfig.

I think it is automatically enabled now.

What is your output with `grep UNIX98 .config` ?

mehlkelm · 07-25-2005, 03:20 PM

Yes UNIX98 is indeed already in the kernel.

So, anyone knows another possible solution?

The thing is, I can log in just fine when I boot the 2.4.30 kernel on the same system. I can also log in with the 2.6.12 kernel as root.
The only thing that gives me no gui just the "error creating child process" is logging in with 2.6.12 as non-root.

Do you run udev in your Debian system ? Also hotplug is enabled ?
Have you a /sys directory ?

Yes. I am able to log in as root and gnome auto mounts my firewire HD when I turn it on, for example.

I have to check that when I get home. I remember having a bit a mess in my fstab. I dont really know which of the sys, proc and devfs I really need and how to integrate them in fstab.

Edit:
Here at work on my laptop (also debian & 2.6.12.2), where everything works perfectly, I have a /sys system but no /sys entry in fstab

Open a terminal as your user in your laptop, then type :

Code:

ls -l `tty`

Note the output, then compare it with your desktop

mehlkelm · 07-26-2005, 02:45 PM

I can't see a difference.
On both the good and the bad system, the command gives me something like

Code:

crw-------  1 stefan tty 4, 0 2005-07-26 21:26 /dev/tty1

on a text only VT.

on graphical x terminal I can only check the ouput of the good system, obviously

Code:

crw--w----  1 stefan tty 136, 0 2005-07-26 21:26 /dev/pts/0

Does this tell you something?

mehlkelm · 07-26-2005, 03:49 PM

I deinstalled udev, cleaned /etc/udev and reinstalled again.
Now I can login again.

Thanks for the hints!
