I have an IBM Aptiva 2174-590.  The video card is Number 9 model SR9 with
a Savage4 processor and 8 MB of video memory SDRAM.  The RAMDAC is
Internal DAC.

When I tried to install Red Hat 6.1, I could not use the graphical
installation method.  The system would hang.  So I used the text
installation method.  That worked just fine so I thought.  I can boot
Linux and shut the system down just fine if I never issue "startx".  When
I issue "startx" GNOME gets started (whether I installed it or not) and it
seems to work just fine until I go to Logout or shutdown the system.  When
the Graphics interface ends, my system hangs.  The power button won't even
work.  I have to unplug the machine to turn it off.  Can you help me?

Thanks,
