This message can safely be ignored.

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).

9.4. PowerPC Architectures

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

Badness in smp_call_function at arch/powerpc/kernel/smp.c:223

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

cause the system to hang.

• 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.
