[SOLVED] nvidia-340xx: ignoreABI server flag is not applied

Wild Penguin · 2021-11-26 12:04:54

Hi,

I'm probably missing something very obvious.

I'm using MBP5,5 and hence stuck on the nvidia-340xx branch (or Nouveau, which has it's own problems). Currently the driver requries ignoreABI since the driver is not being updated anymore. I have this in /etc/X11/xorg.conf.d/20-nvidia.conf:

Section "Files"
  ModulePath   "/usr/lib64/nvidia/xorg"
  ModulePath   "/usr/lib64/xorg/modules"
EndSection

Section "Device"
  Identifier "nvDevice0"
  Driver "nvidia"
  VendorName "NVIDIA Corporation"
  # BusID "PCI:2:0:0"
EndSection

Section "ServerFlags"
  Option "IgnoreABI" "1"
EndSection

However, Xorg does not seem to parse that option (after starting lightdm):

I can:

manually run Xorg -ignoreABI, and the server now starts!
Remove the section part from 20-nvidia.conf. Now I can start a display manager, but it is not using nvidia (obviously).

Any ideas? Is there something wrong with the 20-nvidia.conf syntax? It is entirely similar to the example file provided by the AUR packages (which I tried first - I only made some edits to see if Xorg is parsing the file at all!).

Cheers!

We don't know the specifics of how Antergos configures their distribution. You will need to ask on their forums.

Closed. Dust binned.

It has been asserted that the only thing Antergos about this system is the host name -- along with Antergos being a dead project.
I have accepted this assertion and restored this post to Kernel and Hardware.

Hi,

Yhank You @ewaller. Indeed this is running Arch, I believe I should probably change the hostname to remove confusion! It's just been more convenient this way / left this way because of lazyness. At some point some device in my LAN cared about that hostname, but doesn't anymore...

As for the issue: I've solved it, just now as I was typing a reply . I was about to comment I don't have many ServerFlags sections, and as I checked this, I found out the problem!

More details: I was about to ask here if one can dump the configuration Xorg has parsed and found (I think there isn't, but it would be a good feature). So I manually started to re-look at the configuration files in /etc/X11 and /usr/share/X11. I was about to write here I don't have many ServerFlags sections ... and found out a configuration file I had made previously. Since this is an MBP, and I've had various problems with it's GPU and buggy drivers (an old NVidia card 9400M). As such I've deemed it necessary to enable the good old CTRL+ALT+Backspace. So, I've made a configuration file with another ServerFlags section in /etc/X11/xorg.conf.d. And, it seems that X.org does not combine (despite containing different flags) multiple ServerFlags sections but only uses the last ServerFlags section. The configuration file in question has a priority number of 99-. Moving the IgnoreABI into the latter file is one workaround.

As a general recommendation, it would suggest to put all ServerFlags into one file only. But many examples have ServerFlags in a single file (named to reflect to the configuration piece they are configuring, and usually contain a lot of other stuff than just the ServerFlags section - one such example in this thread), and this kind of issue might arise easily arise if the user doesn't realise there can be only one ServerFlags section. One might assume that ServerFlags sections are combined! (They are not, and the documentation doesn't reflect on this).

Marking as [SOLVED]. Thanks all! I believe this is an example of the usefulness of describing the problem and troubleshooting steps being taken properly. By doing that, the solution will often just appear! .

TL;DR: There were two ServerFlags sections hidden in the configuration files in /etc//X11/xorg.conf.d after all!
