(Assuming you have a Dell Latitude D630)
I guess the thing to try would be to try updating your display drivers. Head to http://www.intel.com/p/en_US/support/detect/
and install updates if they are suggested. If nothing is suggested, try getting the latest from Dell at http://www.dell.com/support/drivers/us/ ... 2731103352
After installing those, a system restart wouldn't really be needed, but I suggest you do it regardless just to be sure.
If that doesn't help, try downloading and installing https://love2d.org/builds/love-20120828 ... efault.exe
, then downloading the "Source" package from the Mari0 download page.
