Hi All,

   We are having nearly 30 machines DELL optiplex 745 machines running with Ubuntu Linux 14.04 LTS .

   The screen display font is garbled due to which screens are not displayed properly.

  I have tried to change the /boot/grub/grub.cfg, VGA parameter and nomodeset parameters, but still the issue is seen.

Orginal grub.cfg:

linux   /boot/vmlinuz-3.13.0-83-generic root=/dev/sda2 ro  consoleblank=0 vga=768 nomodeset net.ifnames=0 biosdevname=0 usbcore.autosuspend=-1

Modified the Xorg.conf to load as an intel  and Vesa driver, but no success.

Could someone provide ideas to fix this issue.
