Once you are through with the installation of PCQLinux 2007, you can apply the following tweaks to get the distro to work smoothly on your machine.

• First the graphical login is disabled. To fix this issue, after logging in as root, edit the file /etc/inittab using vi. Locate the line that starts with 'id' and change it to look like 'id:5:initdefault:'
• Save the file and reboot. But before making this change, run startx command and see if your x-server is working. If not configure xserver first by typing system-config-display command.
• Now reboot your computer and you will be greeted with a graphical login screen. Login as root as this is the only user created at installation time.

Now create another normal user.

• Disconnect your PC from any broadband Internet connection, if present. First disable all the unwanted services including yum-updates. This is a service that can make your system hang and crawl on performance as soon as you start up, as FC starts the autoupdate process without confirming with the user. Subsequently, you can turn off the graphical tool pup (package updater) that pops up. You can now connect the broadband modem and enjoy surfing.
• Now edit the /etc/grub.conf file and increase the timeout value to 20 secs. Also remove unwanted entries (for example, home users can remove the xen kernel entry).

Problem: I have installed PCQLinux 2007, but during start up when processes are starting continuously a message saying 'timer went backwards...' is shown. The notebook I have installed PCQLinux has a core duo processor. Now when I enter the startx command, by default, it enters the gnome desktop. How should I login to the KDE desktop?

Also I found the clock moves very fast, for each second the clock seems to count 2 secs. I changed the time in BIOS but still after logging in Linux, it shows wrong time that changes at a faster speed. I would also want to know how I can login to the different desktops type-Home, Media Center, Scientific or Development? All I found was one icon in the gnome desktop, which when double clicked installed something related to Java. Both the Xen written and non-written boot options at booting time, after giving startx command, lead you to the gnome desktop.

Solution: For the issue of fast moving clock, open the file named grub.conf, found in /boot/grub, in a text editor. There will be one or more lines which say:

kernel

To the end of this line, add clock=pit, after a space. For example, currently I am running FC6 on my notebook and have the following line:

kernel /boot/vmlinuz-2.6.18-1.2868.fc6 ro root=LABEL=/ rhgb quiet

So this line will be changed to:

kernel /boot/vmlinuz-2.6.18-1.2868.fc6 ro root=LABEL=/ rhgb
quiet clock=pit

Now reboot the machine to see it working.
