Dear Linux folks,
On the Dell OptiPlex 7021 with a dedicated Nvidia card, the monitor is
only connect to that, Linux 6.1.39 does not display any messages, and
the GRUB messages stay until the X.Org X Server starts.

[drm] Initialized simpledrm 1.0.0 20200625 for simple-framebuffer.0
on minor 0
I disabled `CONFIG_FB`:
$ grep -e FB -e SIMPLE /boot/config-6.1.39.mx64.450
CONFIG_NET_SCH_SFB=m
CONFIG_SYSFB=y
CONFIG_SYSFB_SIMPLEFB=y
# CONFIG_IFB is not set
CONFIG_DRM_SIMPLEDRM=y
CONFIG_FB_CMDLINE=y
# CONFIG_FB is not set
# CONFIG_USB_SERIAL_SIMPLE is not set
# CONFIG_CRYPTO_CFB is not set
# CONFIG_CRYPTO_OFB is not set
The Linux config works on a Dell Precision Tower 3620 with dedicated AMD
graphics card.
efifb: probing for efifb
efifb: framebuffer at 0xa1000000, using 3072k, total 3072k
efifb: mode is 1024x768x32, linelength=4096, pages=1
efifb: scrolling: redraw
efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
Does Simple DRM FB driver support systems with Nvidia graphics card, or
do I need to build efifb, and I am mistaken that Simple DRM frame buffer
driver should replace it.
Please find the Linux messages and configuration attached.
Kind regards,
Paul
