ATI RADEON 7500 PCI Graphics Controller Installation Guide
Messages
Xserver messages are typically logged to /var/X11/Xserver/logs. The two files that contain the messages are:
/var/X11/Xserver/logs/Xf86.*.log /var/X11/Xserver/logs/Xstartup.*.log
Where * is the display instance of the Xserver, which is usually 0. The Xstartup.*.log file contains messages from the X loader. The Xf86.*.log file contains messages from the Xf86 Xserver. The Xf86.*.log file is the file that should be checked first, should problems arise.
