DRI3 not working on i5-3570

Hello everybody,

Xorg on my pc using an i5-3570 without a graphics card is crashing, unless I add
> Option      "AccelMethod"  "uxa" # fallback
to /etc/X11/xorg.conf.d/20-intel.conf.

I've heard that there are some issues with Intel's graphics drivers.

1. Should I just stick with uxa? Test the other drivers? Use modesetting?
2. Should I report this somewhere? It kind of has already been reported in 2013 but nothing ever happened since then.

thanks

Re: DRI3 not working on i5-3570

use modesetting should pretty much be "the fix" for all sorts of intel weirdness, but what's the xorg/journal crash log? the bug report you linked reads like fglrx which is amd and irrelevant today anyway

How is graphics acceleration on modesetting? Last time I tried it, it was really bad (compositor already took my pc down to ~ 5 fps)

Re: DRI3 not working on i5-3570

Works fine for my usecases but if you think it's slow then sticking to UXA will probably be best for the time being, if you really want to try a bug report you can do so here: https://gitlab.freedesktop.org/xorg/dri … l/-/issues but the driver is pretty much in development limbo and it's unsure on if or how this will get fixed.

If it's indeed tooslow™ w/ modesetting please post an xorg log for that as well.

I've been using modesetting for a day now and haven't had any major issues. Thanks @V1del
