I have purchased a HCL laptop model no. HCL Notebook P28-P2802.
I have installed Windows XP successfully. I tried installing RedHat Enterprise Linux 5. All went smooth.
But after the initial booting, i am not able to view the desktop or login screen. When this stage comes, the laptop screen flickers..horizontal and vertical lines appear simultaneously..I tried restarting the machine and all sorts of things but the flickering occurs in the same stage.
Even we addedd the screen mode 800x600 in x11..still same.
this is problem with misconfiguration. Boot the Laptop into runlevel 3 and reconfigure the Xorg.conf.
# system-config-display --reconfigure
Then Go to runlevel 5 u will get the Display
