Intel DDX driver should probably be dropped

[NanoSector]

On systems that support KMS (which pretty much means every system after 2007 or something), the Intel DDX doesn't add any value:

• https://packages.debian.org/sid/x11/xserver-xorg-video-intel

In fact it causes more trouble than it's worth, plus it's a messy codebase maintained by AFAIK one person, compared to a whole team for the modesetting driver.

It's mostly a YMMV scenario though as some users are experiencing tearing issues and the like but overall it should cause less issues than the Intel DDX driver.

Does this mean that on systems prior 2007 Xorg won't work if we do not include this? I'm not sure if this is a good idea. Maybe I'm a bit old, but I don't see that 2007 is that far in the past 😬

I also dont think there is any need to rush into doing this right now. There is no real benefit because there are just as many reports of issues with the modesetting driver as there are with the intel driver.

@karasu0: KMS goes back much further afaik.

@lots0logs: There's no rush in this but I'm just bringing it up as an idea.

hi devs , on a similar note, I noticed video tearing in browsers(chromium/firefox/opera) with intel ddr/i915 driver on Sandybridge mobile core i3-2330m.

This fix fixed it for me. https://wiki.archlinux.org/index.php/intel_graphics#Tear-free_video

Also where do i file bugs for such usecases ? If you guys rely solely on arch packages for this stuff, I think that would be the right place then.

@sarfarazahmad89 modesetting should eliminate tearing. No bug has to be reported as this behavior can be worked around and is documented.

Fedora also switched to modesetting now:
