The following notes apply to x86_64 Architectures:
• If your system uses an
Intel 945GM
graphics card, do not use the
i810
driver. You should use the
default
intel
driver instead.
(BZ#468218)

• On dual-GPU laptops, if one of the graphics chips is Intel-based, the Intel graphics mode cannot
drive any external digital connections (including HDMI, DVI, and DisplayPort). This is a hardware
limitation of the Intel GPU. If you require external digital connections, configure the system to use
the discrete graphics chip (in the BIOS).

5.30. xorg-x11-drv-nv
xorg-x11-drv-nv provides a driver for NVIDIA cards for the X.org implementation of the X Window
System.
• Improvements have been made to the 'nv' driver, enhancing suspend and resume support on some
systems equipped with nVidia GeForce 8000 and 9000 series devices. Due to technical limitations,
this will not enable suspend/resume on all hardware.
(BZ#414971)
128
• The nv driver for NVIDIA graphics devices does not fully support the DisplayPort digital display
interface. Connections from DisplayPort video devices to DisplayPort monitors are unsupported
by the nv driver. Internal laptop and notebook displays that use Embedded DisplayPort (eDP) are
also unsupported. Other connections, such as VGA, DVI, HDMI and the use of DisplayPort to DVI
adapters are supported by the nv driver. To work around this limitation, it is recommended that the
"vesa" driver be used. (

The following note applies to x86_64 Architectures:
• Some machines that use
NVIDIA
graphics cards may display corrupted graphics or fonts when
using the graphical installer or during a graphical login. To work around this, switch to a virtual
console and back to the original X host.

5.31. xorg-x11-drv-vesa
xorg-x11-drv-vesa is a video driver for the X.Org implementation of the X Window System. It is used as
a fallback driver for cards with no native driver, or when the native driver does not work.
The following note applies to x86 Architectures:
• When running the bare-metal (non-Virtualized) kernel, the X server may not be able to retrieve
EDID
information from the monitor. When this occurs, the graphics driver will be unable to display
resolutions highers than 800x600.
To work around this, add the following line to the
ServerLayout
section of
/etc/X11/
xorg.conf
:
Option -"Int10Backend" -"x86emu"
