Black screen after updating xorg-server

and X did not start. I had to roll back to older versions of the packages.

Question: what if you block for updating, like:

# pkg lock xorg-server и xf86-video-sis,
can this somehow affect the operation of the operating system in the future and programs in general?​

I saw the PR but thought better to vet here first

I have a laptop with nvidia graphics that require nvidia-driver-340

Having same issues with blank screen

I did change pkg repo from latest to quarterly to fix this issue

Main problem seems to be xorg-server-1.20.14,1 (quarterly) works but xorg-server-21.1.4,1 (latest) does not

Looking at support for nvidia-driver-340 I discovered the below

"The Linux 340.* legacy driver series is the last to support the G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Support for X.Org xserver version 1.20 was added to the 340.* legacy driver series with version 340.107, and support for Linux kernels up to Linux 5.4 was added with version 340.108. No further releases from the 340.* series are planned."

So it seems legacy graphics are no longer supported and suspect this is the issue others are having, does that sound right?

If so, many thanks for the support over the years but nothing lasts forever :cool:
