Description Bill Nottingham 2009-02-16 21:13:35 UTC
Description of problem:

After loading the intel KMS support with 'modprobe i915 modeset=1', Xv no longer works.

[notting@nostromo: ~]$ xvinfo 
X-Video Extension version 2.2
screen #0
 no adaptors present

The relevant portion of the log appears to be:

(II) intel(0): [DRI2] Setup complete
(**) intel(0): Kernel mode setting active, disabling FBC.
(**) intel(0): Framebuffer compression disabled
(**) intel(0): Tiling enabled
(==) intel(0): VideoRam: -1 KB
(II) intel(0): Attempting memory allocation with tiled buffers.
(II) intel(0): Tiled allocation successful.
(WW) intel(0): Disabling Xv because the overlay register buffer allocation failed.

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Version-Release number of selected component (if applicable):


How reproducible:

Well, only booted once so far, but there's no reason to think it isn't repeatable.

Steps to Reproduce:
1. Load modesetting driver
2. Start X
3. Attempt to use Xv
Actual results:


Expected results:

I still believe that /var/log/Xorg.0.log would be useful.

No, it's ok, I'll take it from here - thanks.

Remove needinfo.

Comment 4 Kristian Høgsberg 2009-02-18 23:08:33 UTC
xorg-x11-drv-i810-2_6_0-6_fc11 should bring back the textured xv adaptor.

It still fails.

X-Video Extension version 2.2

 no adaptors present

Comment 6 Michael Monreal 2009-02-20 15:30:30 UTC
What is the "correct" way to enable KMS for Intel?

I tries "options i915 modeset=1" in one of the modprobe.d/ files but with that, X never really draws anything after boot and I cannot switch to a VT either...

Comment 7 Bill Nottingham 2009-02-20 15:37:40 UTC
With kernel >= 0.122, it should be enabled by default. Otherwise, you have to load i915 with modeset=1 before starting X.

Comment 8 Bill Nottingham 2009-02-27 20:32:16 UTC


it works now again.
