[SOLVED] ThinkPad T540P and onboard NVidia problems

Hello,

I recently installed Arch on my T540P, and for some reason I can't disablde the nvidia GPU. The "nvidia" driver is still being loaded during boot, even though I blacklisted it. I would like to do it the BumbleBee way.

In other words, if I try to turn the card off with the BBSwitch, the output is

sudo tee /proc/acpi/bbswitch  <<<OFF
dmesg |tail -1
[  415.585860] bbswitch: device 0000:01:00.0 is in use by driver 'nvidia', refusing OFF

I have removed all nvidia modules from /etc/mkinitcpio.conf (and yes regenerated the initramfs!)

I also have blacklisted the "nvidia" and "nouveau" in /etc/modprobe.d/****_blacklist.conf files.

I'm running GNOME on Xorg, and the only xorg config files are

ls /usr/share/X11/xorg.conf.d/
10-nvidia-drm-outputclass.conf  40-libinput.conf
10-quirks.conf                  70-synaptics.conf

ls /etc/X11/
xinit  xorg.conf.bak  xorg.conf.d  xorg.conf.nvidia-xconfig-original

ls /etc/X11/xorg.conf.d/
00-keyboard.conf

EDIT:

another display issue I have is that after shutting down or hibernating/sleeping the laptop, I only get black screen when turning back on / resuming. I have to hard power off the laptop with the power button to get around this. I guess this is a problem with the graphics drivers as well, could anyone help me debug it?

The blacklist config files are blacklisting both nvidia and nouveau drivers. Also the bumblebee config file already has blacklisted different nvidia drivers. Still I can't kill the nvidia card with

sudo tee /proc/acpi/bbswitch  <<<OFF
dmesg |tail -1
[  662.662778] bbswitch: device 0000:01:00.0 is in use by driver 'nvidia', refusing OFF

Can anybody help me here?

Re: [SOLVED] ThinkPad T540P and onboard NVidia problems

Please use [ code ] not [ quote ] tags for pasting command output.  This is likely GNOME trying to be intelligent. Have you enabled the  bumblebee service? That should run before GNOME does and prevent it from loading. What are the contents of your blacklist files? There was a similar issue in this thread https://bbs.archlinux.org/viewtopic.php?id=229001 maybe you get some pointers from that.

And a bump is still a bump, although it's better with the added information, that info could have been appended to the OP, please don't make a habit of bumping.

Thank you very much for your reply. I promise I won't bump anymore, I was just getting a bit desperate as I wasn't getting anywhere

The bumblebee is running

systemctl status bumblebeed
● bumblebeed.service - Bumblebee C Daemon
   Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2017-10-25 16:10:16 EEST; 9min ago
 Main PID: 407 (bumblebeed)
    Tasks: 1 (limit: 4915)
   CGroup: /system.slice/bumblebeed.service
           └─407 /usr/bin/bumblebeed

However, how can I make sure it is being run before the gdm/GNOME service? I think this is the issue, as my blacklist files contain these lines:

blacklist nvidia
blacklist nvidia-drm
blacklist nvidia-modeset
blacklist nvidia-uvm
blacklist nouveau

I also added "After" flag for the gdm service at  /etc/systemd/system/display-manager.service and it looks like:

[Unit]
Description=GNOME Display Manager

# replaces the getty
Conflicts=getty@tty1.service
After=getty@tty1.service bumblebeed.service

# replaces plymouth-quit since it quits plymouth on its own
Conflicts=
After=

# Needs all the dependencies of the services it's replacing
# pulled from getty@.service and
# (except for plymouth-quit-wait.service since it waits until
# plymouth is quit, which we do)
After=rc-local.service plymouth-start.service systemd-user-sessions.service

# GDM takes responsibility for stopping plymouth, so if it fails
# for any reason, make sure plymouth still stops
OnFailure=plymouth-quit.service

[Service]
ExecStart=/usr/bin/gdm
KillMode=mixed
Restart=always
IgnoreSIGPIPE=no
BusName=org.gnome.DisplayManager
StandardOutput=syslog
StandardError=inherit
EnvironmentFile=-/etc/locale.conf
ExecReload=/bin/kill -SIGHUP $MAINPID

[Install]
Alias=display-manager.service

so the gdm service should be run after the bumblebee service has started? However I can see the nvidia module being loaded.. Is there any way to see what is loading the nvidia driver?

Re: [SOLVED] ThinkPad T540P and onboard NVidia problems

I got a bit further again, I added nomodeset to the kernel boot options, now however the bootup hangs, I tried the fix (adding acpi_osi params to kernel boot options) but still the machine seems to hang.

I'm not sure if it is the NVidia GTX730M, the user in the thread you linked had a newer version of the nvidia graphics card. I tried different acpi_osi flags but for now I haven't got any success.

EDIT: Got a success by removing the nomodeset flags from boot options but adding "acpi_osi=Linux" there instead! I'm now having 5 watts less power drain Hope this helps someone else too.
