GNOME 3.16 cannot login.

Hello everyone!

Ever since GNOME 3.16 hit the Tumbleweed repos, I’ve been unable to login using gdm as my display manager. I have no idea what is causing this, and after hours of search, I couldn’t find anyone having the same issue. Selecting Gnome Wayland from the gdm screen works, but it is so buggy. Selecting either Gnome or any other WM causes the same error: after I enter my login password, the screen goes black for a second and it returns to the gdm login screen.

The only thing that seems to work is to replace gdm with lightdm, but by doing so some core components stop working ( lock screen, for example).

I’m using the open source radeon drivers, if it’s important in any way.

Any help would be greatly appreciated, it’s driving me insane.

Thank you.

Since the update to 3.16, “gdm” runs under Wayland. And Wayland seems buggy at present. Switching to “lightdm” avoids Wayland. There’s also a configuration change possible to tell “gdm” to run under X instead of under Wayland.

I have problems with gdm/Wayland using Intel graphics, and have posted bug reports.

I tried on an older computer with Nvidia graphics and nvidia drivers, and the gdm login screen never comes up (it seems to start then crash in a loop).

I have not seen any bug reports related to radeon graphics, so maybe you should consider making such a report.

Thank you for your reply!

Have you tried running gdm under X? Does the configuration change consists of uncommenting the line

WaylandEnable=false

in “/etc/gdm/custom.conf” ? If so, have you tried it? Personally, I have and the results are the same.

Yes, this is the configuration change.
According to bug 925946 the problem was in the i915.ko graphics driver for Intel, but since you are using radeon, you should be witnessing something different.

I understand, thank you for your reply. Do you have any suggestions, or should I just wait until it ( hopefully) gets fixed?

Well, using lightdm is not so bad, until they fix things up.
You may also try an earlier kernel (on my box 3.19.1 ran much smoother than 3.19.3…) or try to update to the 3.19.3-3.1 currently on the Kernel:stable repo.
GDM 3.16 makes a different use of the display and VTs, for instance it keeps VT7 to gdm, while placing users all over the others…
maybe the radeon drivers are not happy with that, while lightdm still switches over the graphical desktop to VT7 for the first user.
If that is the case, the only option I see is getting rid of gdm 3.16 until they fix it.
By the way, other strange things happen with Gnome 3.16, see bug 920510 as an example.

Well, up to this point, I had no trouble with the radeon drivers regarding gdm being on VT7, strange. Yes, I also noticed the problem with gparted. Also, I cannot use libreoffice since it crashes X, no idea what’s going on there either.

Looks like I’ll stick with lightdm for the time being. Hopefully these problems get fixed soon.

Anyway, thank you for your help. Cheers!
