HI

I was just assigned a laptop with a pre install windows 7 in it. I decide to dual boot this server with cent os 5.5 , i did a "linux text " at the boot prompt as anaconda was not able to display the graphis screen ( it was barely viable ) . The installation happened perfect , but when i start x windows " startx" or init3 , i can barely see the display. I dont know where the issue lies , what module do i need to load .The display is barely visible .

Thanks for all the help !!

Are you running on the mains charger?

Is there some sort of key configuration on your laptop to adjust the brightness of the display?

Kind Regards,

Keith

Have you installed, and run "system-config-display"? Unless the hardware was successfully configured at install time, which it obviously was not due to the difficulties you had with the graphical installation, your /etc/X11/xorg.conf or similar configuration files are not well configured.

Find out the resolution of your laptop display screen, be sure to select an LCD screeen of the matching size, and see how it goes. If you have an NVidia chipset, you may need to install NVidia's drivers for best performance, but this should get you started.
