9.3. 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.
• On an
IBM T61
laptop, Red Hat recommends that you refrain from clicking the
glxgears
window
(when
glxgears
is run). Doing so can lock the system.
To prevent this from occurring, disable the tiling feature. To do so, add the following line in the
Device
section of
/etc/X11/xorg.conf
:
Option "Tiling" "0"
• Recording needs to be manually enabled on
Dell M4300
and
M6300
. To do this, perform the
following steps:
1. Open
alsamixer
.
2. Press
Tab
to toggle
[Capture]
in the
View
field (located at the upper left part of the menu).
3. Press the
Space
bar.
4. To verify that recording is enabled, the text above the
ADCMux
field should display
L R
CAPTUR
.
• If your system uses an
Intel 945GM
graphics card, do not use the
i810
driver. You should use the
default
intel
driver instead.
• 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).

• When using
Alt
-
SysRq
-
W
to debug, the following warning message will appear:

Afterwards, the system will also warn that it will hang. This message should be ignored as it will not
cause the system to hang.

Dell M4300
and

. To do this, perform the
following steps:
1. Open
alsamixer
.
2. Press
