[solved] Gnome not starting automatically (Skylake, nVidia GTX 980M)

stueja · 2015-10-18 22:03:41

Hi,

Edit:
Solution: remove gdm, install sddm, or lightdm.

pacman -R gdm
pacman -S sddm
systemctl enable sddm

/Edit

on my system (Skylake laptop with nVidia GTX 980M), gnome does not start after reboot with systemctl enable gdm.
The only message I can see in the console then are pictured here:

If I switch to console 2, login and systemctl start gdm, gnome shows up.

If I disable gdm, reboot, and start gdm in console 1, the screen blanks out. Only in console 2 I can systemctl start gdm, and gnome will show up. However, after I entered username, Enter, password, Enter, the screen stays gray. I have to switch consoles to make the desktop show.

How can I make gnome start automatically with the nvidia driver?

Intel microcode update is in grub as per

menuentry 'Arch Linux' --class arch --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-be50560c-1b72-4040-8a24-3676a533164b' {

	insmod gzio
	insmod part_gpt 
	insmod fat

	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd4,gpt1 --hint-efi=hd4,gpt1 --hint-baremetal=ahci4,gpt1  9249-C799
	else
	  search --no-floppy --fs-uuid --set=root 9249-C799
	fi
	echo	'Loading Linux linux ...'
	linux	/vmlinuz-linux root=UUID=be50560c-1b72-4040-8a24-3676a533164b rw  quiet

	initrd	/intel-ucode.img /initramfs-linux.img
}

nvidia drivers are installed

pacman -Rdds --noconfirm nouveau-dri xf86-video-nouveau mesa-libgl 
pacman -S --noconfirm nvidia lib32-nvidia-libgl nvidia-libgl nvidia-utils xorg-server-devel

I had the same issue, you have two options either downgrade gnome to 3.16 or disable gdm and install lightdm. The lightdm option would be the easiest.

Amanda S · 2015-10-19 03:24:18

Sddm is great too. Slim as well. There are so many options!

stueja · 2015-10-19 07:02:14

bkuma75, Amarildo,
thank you very much. This points me into a direction which I have not tried so far. I'll try that and report back.

stueja · 2015-10-19 07:27:14

Amarildo,
I tried SDDM first.

pacman -R gdm
pacman -S sddm

(I had to reinstall nvidia drivers, because I reverted back to nouveau for a test

pacman -Rdds nouveau-dri mesa-libgl
pacman -S nvidia nvidia-libgl
reboot

)
I forgot to systemctl enable sddm before boot, so I ran systemctl start sddm and... it came up in a second! I could login
a) without, in nouveau/gdm: an extremely slow mouse on "username" screen and double first character in "password" screen
b) without, in nvidia/gdm: switching between consoles to have the desktop show up

The desktop looks a little different now (a bottom bar is there now, the top bar looks different), but I will play around with that. Hey, it's only a month with Arch now, so enough to play around with.

Thank you very much, bkuma75 and Amarildo, for your help!

Amanda S · 2015-10-19 09:13:22

Glad it worked! And welcome to Arch.

Could you show us what bottom bar is that? I remember using sddm with MATE and XFCE and it didn't interfere with them.

stueja · 2015-10-19 18:28:55

Thank you very much, I feel welcome
It's just like here (https://mkslack.github.io/pkgBuildBot/c … g-nc10.png), the status bar or task bar at the bottom, however without the "Show Desktop" icon on the far left.
Gnome with GDM did not show that, lightdm also not.

Could you perhaps be seeing this? https://wiki.gnome.org/Projects/GnomeFlashback
If so, then you are probably just starting the wrong session. Don't remember exactly how SDDM looks like by default, but you should have the option there somewhere to change session.

Oh, yes, this looks very similar. I need to do a reinstall this afternoon/evening (or tomorrow, depending on today's womens' acceptance factor ) and will check for the flashback or session settings.

So, SDDM is starting again.
I have, unfortunately, no possibility to change session types. The dropdown reads "Gnome Classic" and is not really a dropdown, because it does not drop down on a single entry, I think.

Edit:
I am seeing my desktop as in this screenshot, taken directly from my desktop.

Edit 2:
Reinstalled gnome and -- voilà -- Gnome Classic, Gnome, Failsafe and Gnome on Wayland in the dropdown.
Thank you very much for the hint! )
