Parallels

Resolution

1. Find the grub menu.lst boot loader file: /boot/grub/menu.lst (e.g. using this command: "find / | grep menu.lst")


2. In the grub boot loader configuration file, change the VGA setting:
   
   kernel /boot/vmlinuz root=/dev/hda2 vga=0x0317 selinux=0 resume=/dev/hda1 splash=silent showopts
   


3. Start xmode utility with resolution and frequency parameters to receive parameters for the record in /etc/X11/xorg.conf configuration file:
   
   # xmode -x 1024 -y 768 -r 80
   


4. For instance, you may receive:
   
   Modeline "1024x768" 86.18 1024 1088 1200 1376 768 769 772 803
   


5. Add the record you received from xmode into the file /etc/X11/xorg.conf. For instance, the record will be:
   
   Modeline "1024x768" 86.18 1024 1088 1200 1376 768 769 772 803
   


6. Put comment signs in the beginnings of all the strings for 800x600 screen resolution, for instance:
   
   #Modeline "800x600" 40.0 800 840 968 1056 600 601 605 628 +hsync +vsync
   #Modeline "800x600" 36.88 800 832 912 1024 600 601 604 621 +hsync +vsync


7. Restart the guest OS.
