Problems with Xorg

[Joshua Branson]

Ok. I think that I am not suscribed to this list.
Do you can send link from the archive?

If you google it, you can probably find it. Also please not that
running the Hurd in virtual box is probably not the best way to do it.
All of the Hurd developers actually run the Hurd in qemu. :) It's much
better that way.

Now I will send the suscription

Thanks by your response
Where is the another thread?

On the bug-hurd mailing list.

Hello,

FI, I have uploaded a fixed package on debian-ports, so Xorg works
again.

Thanks!! Now Xorg runs correctly.
But It feels that there is a problem with "logout" option from Desktop
Environment or Window Manager.
When I press "logout" option, Xorg don't finish correctly, and mantains the
DE running, and don't allow to return to tty or open any program.

That's a known issue, see the kill_setuid wiki page.

Thanks by the info.

I set a dirty patch adding support for ctrl_alt_backspace in xorg.conf.
When DE crash after logout, I simply press this keycomb to kill Xorg
process.

There is a documented way on

Yes, I used this document to add ctrl_alt_bksp support in xorg.conf, but I
didn't found any solution to logout problem in this.

I've just installed xdm. If I start the DE session from this, the logout
returns correctly to the login screen

Yes, because the X server does not need to be killed in that case :)

Samuel

[Almudena Garcia]

It's correct :)

But my solution cause another problem: If I want to return to tty, I have
to stop the xdm service from the same DE, which It's a bit bizarre ;)

I tried a simple experiment, adding setuid to xinit file, with

chmod u+s /usr/bin/xinit

After do this, I stopped xdm and execute startx to run the DE directly.

And now Xorg finish correctly when I logout!! :-)

I've just check this, executing whoami in the terminal emulator, and It
returns my username, not root

Err, but is the session really running as normal user instead of root?

Oh, interesting, xinit indeed does setuid(getuid()).

Congrats!!! Haha. Are you running the Hurd in a vm? I think I've read
online somewhere that the Hurd can run X fairly reliably, if the Linux
host OS runs the X server, and the Hurd connects to the server as the
client.

If you decide to give this unsolicited advice a try, would you mind
reporting back how it works?
