[SOLVED]Arch gets stuck during boot for about 45 sec before xfce login

jdenoy · 2019-08-12 08:14:09

Hello,

since upgrading from 5.1.15.arch1-1 to either 5.2.5.arch1-1 or 5.2.8-arch1-1 I get the boot stuck on a black screen for about 45 secondes before getting xfce loging screen, also getting complete system freeze from time to time.
Reverting back to kernel 5.1.15.arch1-1 fixes the problem directly, but not sure why.

System is updated at least weekly, and has been done before posting.

I'm not sure what is needed for the troubleshooting, so please fire away your questions.

Read your journal for a slow login.

Moving to NC...

The boot issue might happen due to lack of entropy, if lscpu | grep rdrand gives you output add

random.trust_cpu=on

to your kernel params. Otherwise install and enable haveged.

The system freeze "could" be due to some issues in the i915 kernel module, though as far as I know the issue I'm thinking of should be fixed by 5.2.8.

In any case, post a

sudo journalctl -b

during a faulty boot

does not solve the problem, got at least twice the regular wait...

There's like a gazillion nouveau timeouts.
a) How did you configure the optimus system (if the answer is "huh, what?", read up https://wiki.archlinux.org/index.php/NVIDIA_Optimus )
b) try the nvidia blob

shouldn't the optimus system be used when you actually use the official nvidia drivers?
I've been using the nvidia-nouveau since the beginning without any problems up to theses kernel upgrades. as for the nvidia blob, what's that?

BTW here's my graphics card hw info :

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake)
	DeviceName: Onboard - Video
	Subsystem: Micro-Star International Co., Ltd. [MSI] UHD Graphics 620 (Whiskey Lake)
--
02:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev a1)
	Subsystem: Micro-Star International Co., Ltd. [MSI] GP107M [GeForce GTX 1050 Mobile]
	Kernel driver in use: nouveau

I had a similar issue with gdm and gnome. For me, the solution was to install and enable haveged.

pacman -Sy haveged
systemctl enable haveged

So you didn't read the wiki?

The proprietary driver.

Ok, then after reading the doc, optimus doc is to be followed and applied for nvidia drivers users.
For the nouveau driver users, got to follow the PRIME doc which I did.

drivers loaded fine :

Providers: number : 2
Provider 0: id: 0x67 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 4 associated providers: 1 name:Intel
Provider 1: id: 0x3f cap: 0x5, Source Output, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:nouveau

But still boot delay (no freeze yet, but haven't had time to use gpu intensive apps)

V1del · 2019-08-12 13:15:07

Does blacklisting nouveau prevent these issues? Is it currentliy configured to offload to the nvidia GPU or do you utilise DRI_PRIME=1 on an as needed basis?

No.

optimus is the trademark for the HW config
w/ nouveau you can use prime (though the article seems to suggest it also works w/ the blob, but I'm not sure about that at all)
bumblebee supports either driver
nvidia-xrun only works w/ the blob.

yes blacklisting all nvidia drivers solves the problem, but then no nvidia GPU...

I have the same problem with msi ps63 modern RD. way to use only nvidia card is described here https://wiki.archlinux.org/index.php/NV … phics_only
but in this case laptop has short battery life. Another way is using only intel graphics. You should delete other drivers for this. Disabling nvidia card with bbswitch leads to normal battery life.
So i think that there is problem with nouveau.
Also i have problems with touchpad. It doesn't work after suspend.

upgrade to latest nvidia-dkms solved the problem.
Thanks for everyone's help.
