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
|
|
|
|
|
rotation.
|
|
|
|
|
|
|
|
|
|
Configuration
|
|
|
|
|
|
|
|
|
|
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"
|
|
|
|
|
EndSection
|
|
|
|
|
|
|
|
|
|
Please refer to the intel(4) manual page for information on configuration
|
|
|
|
|
options.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Known Limitations
|
|
|
|
|
- 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
|
|
|
|
|
release.
|
|
|
|
|
- Gray output with integrated TV-out and PAL TVs.
|
|
|
|
|
- EXA support unstable on i845.
|
|
|
|
|
- Some GM965 systems, such as the Thinkpad T61, probe the TV as being connected
|
|
|
|
|
even when no output connector is available. This results in the gnome-panel
|
|
|
|
|
issue noted below.
|
|
|
|
|
|
|
|
|
|
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 applications 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.
