xorg-x11-server/n_xserver-optimus-autoconfig-hack.patch
Stefan Dirsch 6ff43929b0 Accepting request 1189636 from home:jamborm:gcc14test-m 
- Added xorg-xserver-e89edec497ba.patch to fix incompatible pointer
  type error with GCC 14.

If the request is OK, please forward it to Factory soon too so that we
can switch the default compiler.  Thanks!

From 3216e0c618cc330f053ed36a749c8d8cfeb87a2f Mon Sep 17 00:00:00 2001

Subject: [PATCH] autobind GPUs to the screen, (v5)
this is racy and really not what we want for hotplug going forward,
but until DE support is in GNOME its probably for the best.
v2: fix if config or slave config is NULL
v3: fix multi useful slaves
v4: do not unbound GPUs before attaching them
compatibility fix for 5c7af02b10
-- Michal Srb <msrb@suse.com>
v5: Do not use xf86CrtcConfig, it is not filled by nvidia proprietary driver,
only use randr structures.
Auto configure outputs of additional GPUs on start, just like the outputs
of the main GPU are configured.
-- Michal Srb <msrb@suse.com>
DO NOT UPSTREAM.
