Neuer Treiber für Grafikchips von Intel in [testing]

Version 2.0 der Intel-Treiber kann nun getestet werden. Der Treiber heißt nun xf86-video-intel und ersetzt xf86-video-i810. Unter /etc/X11/xorg.conf muß daher auch der Treiber von i810 auf intel geändert werden.

Re: Neuer Treiber für Grafikchips von Intel in [testing]

Gibt's irgendwo eine Liste mit Neuerungen? Abgesehen davon, dass jetzt die neueste i965 Grafikkarte unterstützt wird, sehe ich keine Neuerungen auf der Intel-Linux-Website, oder liege ich da falsch?

Re: Neuer Treiber für Grafikchips von Intel in [testing]

Ich habe auch nur folgende Datei gefunden. Hier steht aber nur, was es kann und nicht, was davon neu ist:

Information for Intel graphics driver users
Eric Anholt

This document provides a brief summary of the Intel graphics support provided
by the xf86-video-intel driver.  More information can also be found in the
intel(4) manual page.

Supported Hardware:

- Full support for 8, 15, 16, and 24 bit pixel depths.
- Hardware accelerated 2D drawing engine support for 8, 15, 16 and 24 bit
  pixel depths.
- Hardware accelerated 3D drawing using OpenGL and the DRI.
- Hardware cursor support to reduce sprite flicker.
- Textured video XV implementation on i915 through i965.
- Hardware overlay XV implementation up through i945.
- Screen resize and rotation.

Technical Notes
- Interlace modes cannot be supported.
- This driver  requires kernel support for AGP, which is included in Linux
  kernels 2.3.42 and higher, and FreeBSD 4.1 and higher.
- This driver may be built against xserver 1.2.0 or newer.  If built
  from git source against an older server, a copy of xserver 1.3.0 source is
  needed to complete the build, which is chosen with the --with-xserver-source
  argument to ./configure.  The compatibility mode with xserver 1.2.0 will have
  limited functionality, in particular by not supporting RandR 1.2 or the
  new Damage 1.1 updated needed for 3D applications to work with display


The driver auto-detects all device information necessary to
initialize the card.  The only lines you should need in the "Device"
section of your xorg.conf file are:

       Section "Device"
           Identifier "intel"
           Driver     "intel"

Please refer to the intel(4) manual page for information on configuration

Known Limitations
- Bug #8534: i830 laptop panels not supported.  The driver
  will fail to recognize them, and only function through VGA output.  Two
  partial DVO chip drivers (ivch and ch7017) are included which contain some of
  the code necessary for i830 laptop panel support, but some I2C debugging will
  be necessary to get those drivers to attach.
- No support for "zaphod mode" dualhead.  This is the mode in which two
  Device sections are placed in the config file, and doesn't support DRI or
  many other features.  Instead, only "MergedFB-style" dualhead is supported.
- No support for X Screens larger than 2048 pixels in either direction
  before the 965.  This reflects hardware limitations in the x direction on
  those older chips, and limits dualhead functionality.  It may be possible to
  extend the limit vertically on these older chips.
- i855 XV may cause hangs.  This was present in the previous release, and no
  workaround is known.
- SDVO TV-out cards not supported.  This should be fixed in the next
- Gray output with integrated TV-out and PAL TVs.
- EXA support unstable on i845.

Common issues not caused by the driver
- Font sizes (DPI) are wrong.  Some displays incorrectly report their
  physical size, which is harmless on most OSes that always assume 96dpi
  displays.  This can be fixed through quirks for specific monitors in the X
  Server, and the output of xrandr --prop along with a physical measurement of
  the screen size in a bug report against the server can help get that fixed.
- gnome-panel is located in the middle of the screen.  gnome-panel places
  itself within head #0's boundaries, which doesn't work well with a second
  head covering the same area as head #0 but larger.
- Older resolution-changing applicationss have poor results in
  multihead systems.  Previous extensions such as RandR 1.1 exposed only a
  single output to client programs, and those requests map poorly to multi-head
  systems.  Currently, those requests map to just one of the outputs in the
  RandR 1.2 environment, and those applications need to be updated to RandR 1.2
  API when available for better results.

The X11R6 version of this driver originally came from XFree86 4.4 rc2.

The XFree86 version of this driver was donated to The XFree86 Project by:
    Precision Insight, Inc.
    Cedar Park, TX

The X.Org version of this driver is maintained by Intel Corporation.

Re: Neuer Treiber für Grafikchips von Intel in [testing]

Ah endlich.
Vielleicht kann ich mit meinem 865G nun endlich meinen Monitor nativ mit 1680x1050 ansprechen. Bisher gabs ja ausschließlich Bios-Modes, wo der nicht dabei ist. Mit dem 2.0er Treiber solls jetzt gehen.
Werd ich mir heute abend gleich mal ziehen.

Na klasse. Ratet mal, welche Grafikkarte ich habe ...

Re: Neuer Treiber für Grafikchips von Intel in [testing]

Wollte gerade diesen Treiber testen, funktioniert aber nicht.

Wenn ich den Treiber installiere und xorg.conf umändere und X11 neu starte passiert folgendes:
1.) Die Auflösung wird viel zu groß: normal hab ich 1400x1050, die Auflösung ist dann 1400x>1050.
2.) Die Farben werden etwas komisch, das ganze Bild bekommt einen Rot/Orange Stich.

Ich habe eine Intel 82852/855GM, ist das das Problem das IceHand (Beitrag über mir) angesprochen hat? oder an was liegt das?
