[opensuse-factory] gdm launch failure
Hi all, I just dup'ed my machine today as well and ran into an issue I believe a bunch of users ran into already. GDM fails to show the greeter with the all famous 'oh no! something has gone wrong' error message. I could track it down to /dev/nvidiactl: the gdm greeter seems not to have sufficient permissions to access this device, causing the error. /dev/nvidiactl is created as crw-rw---- root:video; which obviously is not matching the gdm user's permission. As a quick workaround I just added user 'gdm' to the group 'video', which helped over the problem, but I'm wondering why this would have started to happen now?

Hi But this still doesn't account for the change. I had 11.4 with 3.0.2 and all was fine logging in/out.

Hello, Just to add a personal feedback on the issue. I'm using 12.1 RC1 64 bits, derived by various Milestones upgrades, obtained by "zypper dup" which I installed as virtual machine (VirtualBox 4.1.4). Previously all the attempts to boot always failed due the fact 12.1 boot default was systemd so I switched to sysv and finally system booted ok, but only to console login, no graphical. Then I edited /etc/permission.local and uncomment the line "/usr/bin/Xorg" obtaining X finally starting but only if I login as root or by using "sudo startx". Currently I edited /etc/sysconfig/windowmanager to use "kde" and /etc/sysconfig/displaymanager to use "gdm" Now I can login both into GNOME or KDE, without problems.

Apparently more users start seeing this now as well, see https://bugzilla.novell.com/show_bug.cgi?id=728259 How was the permission on that device handled in the past? What changed and why did we loose it? I'm very tempted of flagging that issue as a blocker, as a big part of nvidia users will be affected by this.

Looks like ACL aren't set to nvidia devices, unlike drm "classic" device : 70-uaccess.rules:SUBSYSTEM=="drm", KERNEL=="card*", TAG+="uaccess" 70-udev-acl.rules:SUBSYSTEM=="drm", KERNEL=="card*", TAG+="udev-acl" there is no similar rule for nvidia. -- Frederic Crozat <fcrozat@suse.com> SUSE -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No idea, what would be required. And if it's possible with NVIDIA at all. But NVIDIA/fglrx RPMs won't work anyway with RC2 becoming the final release due to bnc #619218 ...

Still? We even got X no longer running as root... that would sound rather strange to have kdm suid in this case then (but it would explain why this is no issue).

It would be a workaround forever I guess. AFAIK /dev/nvidia* is not created via udev, therefore not known to udev, therefore no ACLs so no access for the desktop. That's the only reason why we still add users to the video group. So you need to do that for gdm too then.

Ok, thanks.

There is a fallback mode, but the "GL doesn't work" detection code apparently detects things are fine in that case -- no idea why. It'd be weird to have gnome-shell for users and fallback in gdm, though.
