[gentoo-user] Question about new USE flags for xf86-video-intel

[Walter Dnes]

  I'm updating a system that's probably gone 2 or 3 months since its
last update.

====================================================================
!!! The ebuild selected to satisfy "x11-drivers/xf86-video-intel" has unmet requirements.
- x11-drivers/xf86-video-intel-2.20.13::gentoo USE="dri -glamor -sna -udev -uxa -xvmc"

  The following REQUIRED_USE flag constraints are unsatisfied:
    any-of ( glamor sna uxa )
====================================================================

  This is the first time I've run into these options.  A bit of Google
detective work turned up some articles...

http://www.phoronix.com/scan.php?page=article&item=intel_glamor_first&num=1
http://ickle.wordpress.com/2012/06/05/an-evening-with-glamor/

...which give the impression that SNA is the fastest option overall.
The phoronix article also mentioned some instability issues with glamor.
I'll probably be going with SNA.  Does anybody else have any experience
and/or opinions?

I have no idea about performance but I've got udev and sna enabled at this time.

gandalf ~ # emerge -pv xf86-video-intel

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] x11-drivers/xf86-video-intel-2.20.13  USE="dri sna
udev -glamor -uxa -xvmc" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB
gandalf ~ #

Be forewarned, or please report back if you can, but in my case on the
two Intel machines I have (one local, one my 84 year old dad uses) X11
stopped displaying anything after this update. As a quick fix I
removed the xorg.conf file completely to get a desktop back. This was
a couple of weeks ago. Removing xorg.conf worked on both machines and
I haven't gone back to figure out what happened and how to best
address it.

Good luck,
Mark

If you don't miss features I say good riddance to xorg.conf.

Yeah, I agree in general, but in this case how does one determine that
on a remote machine? I run KDE, my dad runs Gnome. How would I know if
things are OK, other than making the change and waiting for complaints
I guess.

Cheers,
Mark

  I was running without an xorg.conf.  This is my HTPC machine, hooked
up to a 50" Panasonic Plasma TV.  It's native 1366x768, but it kept on
coming up 1280x720.  I needed an xorg.conf "Modes" line to bring up
1920x1080 or 1366x768.  As root, I ran "Xorg -configure" and copied
xorg.conf.new to /etc/X11/xorg.conf.  X works now, if I do not specify
the resolution.  It also works with resolution 1920x1080, as well as the
original 1280x720.

  SubSection "Display"
    Viewport   0 0
    Depth     24
    Modes     "1920x1080"
  EndSubSection

  However, X hangs at various other resolutions, notwithstanding that
they're listed in both the TV's EDID and in the xrandr output.  Plus I
have other issues so I'll be starting a separate thread.
