[opensuse] Can't startx without root priviliges.
Hello all, my first mail so hope i'm doing this right. My problem is that I like to boot into rl3 by default, then start Xorg with startx. It doesn't work though, i get errors saying "no xauthority. xxx", "can't find screen.." etc, and that I should set the setuid bit. I can't find log files anywhere to give detail on the errors sorry. xinit gives a slightly different error, but still something about authority/permissions. The only way I can start X from console is either via logging in as the root user, by using sudo, or by switching on the setuid bit on the Xorg binary (which is suggested in the startx error message). So the only sensible way I can get X as a normal user is to set default boot to rl5 in inittab. I'm new to SUSE but not new to gnu/linux, and this doesn't seem like 'normal' gnu/linux bahaviour to me. So is this a problem with my installation (11.4 RC1) or is this the intended behaviour? Guys on IRC seemed to think it was a bug, but if so why the 'informative' error message suggesting I set the setuid bit?

No, this is intended. The setuid root bit from X was removed, so startx as user no longer works by default. If you need it back, uncomment this line in your /etc/permissions.local: /usr/bin/Xorg root:root 4711 and run SuSEconfig --module permissions Ciao, Marcus -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
If your running rc1 your better forwarding this to opensuse-factory@opensuse.org mailing list I have done it for you this time.

Oh, ok thanks. But isn't this creating a n unneccesary security hole, running X as root? Debian, Red Hat etc don't use setuid bit on Xorg, i've checked. Thanks Chris -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The setuid bit has been replaced by posix file capabilities http://www.ibm.com/developerworks/library/l-posixcap.html -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Just not for Xorg. Ciao, Marcus -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Sorry, what? I'm sure you are trying to help but be reasonable; four-word answers are not going to explain anything. Are you saying that Debian/RH have replaced the suid bit on Xorg with POSIX file capabilities, but SUSE hasn't, and that's why the suid bit needs to be set in SUSE? ? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Well, it is rather difficult to read. I'll try to break it down for you.

ah, there were two words of three letters :^)

No, he said nothing about Debina/RH.
and that's why the suid bit needs to be set in SUSE? ?
I read that it needs to be set as described earlier, that the "file_caps=1" will not affect the access settings for display/Xorg. -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://counter.li.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
