Display manager doesn't show up on fresh install

jwrona · 2014-10-28 22:23:16

Hello,

recently I betrayed gentoo and installed arch. But I'm having this problem: everything boots just fine, all services are running, but my display manager doesn't show up. There remains systemd log on the screen. I tried gdm and lightdm but no difference. When I switch to another TTY and log in, I can see the gdm process running, also systemctl status gdm.service shows "active (running)". When I restart gdm (systemctl restart gdm.service), it suddenly shows up and works fine.

I'm using laptop with no other screen attached. It has two GPUs, intel and nvidia (Optimus), and I installed drivers for both of them, Nouveau for nvidia. I can only disable intel GPU in BIOS, which I tried and it didn't help. Also there are some ACPI warning in my dmesg, I don't know if it could be somehow related:

Any ideas? Will you help me please?

First off, welcome to a fellow Gentoo expatriate I still love Gentoo -- the penultimate distribution.

I think you are having problems getting X to run. For now, disable the display manager and start X by hand. Log in from the console and run startx and see what happens.
From there, we may want to see your Xorg log. On Arch with systemd and no display manager, Xorg runs as a user. so the logs are in ~/.local/share/xorg. Note that when you use a display manager, the logs will be in /var/log as xorg will run as root (like on Gentoo)

With startx gdm started fine. Here is my Xorg.0.log: http://pastebin.com/wpG3Npn9. I'm not very familiar with Xorg logs, but there seems to be some ACPI problem, like in dmesg.

I took a look through the Xorg log, and it picking up the Intel card, but not the Nvidia. The rather simple twm and startx may not deal with video card switching. Perhaps the more complex display managers are trying to switch to the Nvidia. I don't think the ACPI error is anything to worry about -- at least not in this context.

Unfortunately, I know nothing about Hybrid graphics. I've never had to deal with them. If you've not seen it, you might look at the hybrid graphics wiki page. Also, I am not sure why the Nvidia driver is not getting picked up, especially if you disable the Intel card. I also have not used Nvidia, so I can't help much there either.

did you enable gdm? systemctl enable gdm? :-p

brittyazel: yes I did

I disabled intel GPU in BIOS and X wasn't able to start. Here is log: http://pastebin.com/jJqksmyS. I think there may be something wrong with my nvidia card. Before arch I used bbswitch to turn it off during startup so I don't even know if it was working earlier or not.

I'm going to try bbswitch and see what happens.

[Edit]
So I tried two ways to turn off dedicated card: acpi_call as it is described in https://wiki.archlinux.org/index.php/hy … screte_GPU and bumblebee with bbswitch https://wiki.archlinux.org/index.php/bumblebee. There was some problems with acpi_call but bumblebee seems to work well and my nvidia GPU is turned of by bbswitch module during startup, but display manager still doesn't show up. Now I'm absolutely clueless.
