[SOLVED] i915 - kernel mode setting support for Xorg?

Maniaxx · 2017-06-27 16:22:15

Hallo,
i have an older Compaq nc6120 laptop with i915 chipset. I've set early KMS modules to 'intel_agp i915' with 'xf86-video-intel' driver and everything works properly so far.
As the device is barely able to play HD videos i would like to try 'kernel mode setting driver' instead of the one above so i uninstalled it. The early KMS still works but starting Xorg fails with missing driver. For my Nvidia card i simply uninstalled 'xf86-video-nouveau' and kernel mode setting driver worked for Xorg as well.

Do i miss something here or is it simply not supported for this chipset and 'xf86-video-intel' is mandatory?

Did you remove any intel related configs from /etc/X11/xorg.conf.d/ ?

Maniaxx · 2017-06-27 19:17:36

I still have the section from the wiki with "sna" defined.

Modesetting driver doesn't support older chips

Maniaxx · 2017-06-27 20:06:30

Yep, i expected something like this. Just wanted to make sure i'm not missing something here.

Thanks!

I doubt that there's anything in the modesetting driver that would inherently prevent support on older chips, the issue in this thread clearly is that you still use configuration intended for xf86-video-intel if you want to test how the modesetting driver works, as mentioned remove that file. HOWEVER for older chips xf86-video-intel has a potential to work better, since the SNA support had more time to grow and has potentially less bugs.

Now modesetting/glamour fails with OpenGL 2.1 dependency.
That's unresolvable. The i915 is just GL1.4. GL2 support has been reverted recently.

So no Xorg modesetting/glamour support for the i915 here.

Thanks!

I think you're confuing kernel driver with xorg driver. i915 is a kernel driver, thus responsible for KMS (Kernel Mode Setting). xf86-video-intel is an xorg driver, and has nothing to do with 3D or video acceleration (both are handled by mesa libs, via either vaapi or vdpau). xf86-video-modesetting is also an xorg driver which is nowdays built in, has no separate package anymore. Same applies, it's also an xorg driver, nothing to do with 3D or video acceleration.
Problem you have is that your Pentium might be too old and might not support video acceleration in hardware. Changing the xorg driver (using intel or modesetting) simply won't help because neither is responsible for vieo acceleration to begin with.

What does vainfo and vdpauinfo say? It will list what your gpu supports..
You might also check on using discrete nvidia card for video acceleration if your cou/igp is too old/slow to support modern video formats.

Xorg modesetting/glamour render path usually is faster/better than the legacy one. That's why i wanted to test it. But as stated above its not possible as glamour relies on OpenGL2.1.
Yes, the 'xf86-video-intel' driver does work properly and the laptop is more than 10 years old but i just wanted to know if there's maybe more in the box.
