Re: GDM behaves strangely after gnome 3.6 update

Thanks for the reply, but I can login to gnome, it just takes too long. I do not have the issue mentioned in that thread. Or am I misreading something?

Re: GDM behaves strangely after gnome 3.6 update

GDM 3.6 is very slow. Before installing gdm and a couple of services boot was like, under 5 seconds.

Re: GDM behaves strangely after gnome 3.6 update

Basically what I am trying to figure out is, whether it is problem with GDM or with my migration to systemd.

Re: GDM behaves strangely after gnome 3.6 update

I am quite sure this is GDM- or gnome-related, since I had it all running fine with systemd. The issue first occured when I upgraded GDM from 3.4.1-3 to 3.6.1-2 (full pacman -Syu, so other gnome stuff was updated, too).

Re: GDM behaves strangely after gnome 3.6 update

But when I do systemd-analyze blame I can see that polkit and NetworkManager take too long to start. Have look at my thread:
https://bbs.archlinux.org/viewtopic.php?id=152363

That is why I thought it might be systemd, not Gnome.

This has to be a different issue, although there may be similar cause for the problem. My systemd-analyze blame gives

Re: GDM behaves strangely after gnome 3.6 update

Ok, thank you for the info, I will then look around for other display managers.

Re: GDM behaves strangely after gnome 3.6 update

Same here: gdm 3.6 extremely slow to show. There are few posts about this, making me think that it is not so common.
Initially I was even inclined to think that it is the normal behaviour, then I saw this.

I am on an SSD and updating to 3.6 have also made the boot (more specifically GDM) way slower.

Re: GDM behaves strangely after gnome 3.6 update

I have experimented yesterday and replaced gdm with lxdm, but nothing really changed, Gnome/Cinnamon was still very slow to show.

We must made a distinction between GDM (or other display manager) load time and Gnome load time. Aside from the slowness of Gnome, isn't lxdm faster to load than gdm? If the answer is no, should the problem be related to X?

Indeed. I posted it only as a reference: anyway I don't think that the problems we have after upgrading to 3.6 are normal.
In my case, as in the case of the author of the thread, the difference between GDM 3.4 and GDM 3.6 are so critical in terms of load time that, if everyone is experiencing this, we would have tons of discussion in the forum.

As a further note, I switched to systemd BEFORE upgrading to Gnome 3.6. Using Gnome 3.4, the boot time of systemd was more or less equal to that of initscripts.

Yes, lxdm started a bit faster, but that was never a problem in my case. The real slowness comest after I log it. I have to wait about 15 seconds while my hdd shows minimal activity. It was about 2 seconds before. I returned back to GDM, btw.

Re: GDM behaves strangely after gnome 3.6 update

I've got the same problem here, It probably is not GDM-related, since console login followed by gnome-session (completely without GDM) also takes up to 10 seconds to start, even from SSD. I am totally out of ideas here. I always liked gnome sad

Re: GDM behaves strangely after gnome 3.6 update

Things are much smoother on my fresh arch PC. I have a laptop with relatively slow GDM and gnome startup and login times (after being much faster with gnome 3.4), on my PC everything seems a lot quicker.

Same amount of RAM in both computers (2 gigs).
Similar CPU (2 cores, 2.2ghz on the laptop, 3.0 on the PC)
WD 1TB in PC (7200RPM), WD caviar blue 160GB(5400RPM) in laptop
nouveau on the laptop, ati on the PC (I have a feeling this could be the main reason for the difference)

Considering people are having slow speeds all round even with SSD's....what g-card have you got and what driver are you using?

I was pleasantly surprised by the speed of things on my PC, and my laptop is not very bloated at all. Too bad I never had gnome 3.4 on this PC before so I could do a direct comparison.

Re: GDM behaves strangely after gnome 3.6 update

I have ati / intel switchable on my laptop, and nvidia on my pc. using radeon / nouveau open drivers, all cards with the same issue. So I think that can not be the problem.

Re: GDM behaves strangely after gnome 3.6 update

I found out that when I remove all entries from my monitor configutation in /etc/X11/xorg.conf.d/ GDM starts significally faster. It the needs about 4 secs compared to 11 secs.

Re: GDM behaves strangely after gnome 3.6 update

I don't have monitor entries there, only 10-evdev and 10-quirks. I don't know where this problem comes from, but it has to be somewhere deep in the gnome stuff since it does not matter if I start gdm or gnome-session, both takes ages.
