Book I Chapter 3 Troubleshooting and Configuring Linux Resolving Other Installation Problems 75 4. Press Ctrl+Alt+Backspace to kill the X server. 5. Copy the new configuration file to the /etc/X11 directory with the following command (on Fedora Core systems, change the filename to xorg.conf.new): cp //XF86Config.new /etc/X11/XF86Config You now have a working X configuration file. 6. Reboot the PC by pressing Ctrl+Alt+Del or typing reboot. If all goes well, you go through the normal Fedora Core initial setup screens and (finally) get the graphical login screen. The X configuration file created by using the -configure option of the X server does not display at the best resolution possible. To fine-tune the configuration file, you have to run a utility to adjust the display settings after you reboot the system. The exact utility depends on your Linux distribution, but most distributions include a utility that enables you to configure the video card, monitor, and display settings through a graphical user interface. Resolving Other Installation Problems I m sure I haven t exhausted all the installation problems that are lurking out there. Nobody can. There are so many different combinations of components in Intel x86 PCs that Murphy s Law practically requires some combination of hardware to exist that the installation program can t handle. This section lists a few known problems. For others, I advise you to go to Google Groups (groups.google.com) and type in some of the symptoms of the trouble. Assuming that others are running into similar problems, you can get some indication of how to troubleshoot your way out of your particular predicament. Using Knoppix boot commands The Knoppix Live CD can be a great troubleshooting tool because Knoppix is good at detecting hardware and you can run it directly from the CD. Of course, sometimes you may have trouble getting Knoppix itself started. If that happens, you can try entering Knoppix boot commands at the boot: prompt that appears after you boot your PC from the Knoppix Live CD. For example, if Knoppix seems to hang when trying to detect a SCSI card, you can disable SCSI probing by typing knoppix noscsi at the boot: prompt. Or, if you want the X server to load the nv module (for graphics cards based on the NVIDIA chipset), you can type knoppix xmodule=nv at the boot: prompt. Table 3-2 lists some common Knoppix boot commands.
