I have intel graphics card on my system (Scientific Linux 6.0), but the graphics is so poor as no drivers are installed.So I have installed :xorg-x11-drv-intel-2.21.2-1.el6.elrepo.x86_64  xorg-x11-drv-intel-devel-2.21.2-1.el6.elrepo.x86_64And Updated for dependencies:xorg-x11-drv-synaptics-1.6.2-13.el6.x86_64  xorg-x11-server-common-1.13.0-23.sl6.x86_64  xorg-x11-server-Xorg-1.13.0-23.sl6.x86_64  pixman-0.26.2-5.1.el6_5.x86_64  mtdev-1.1.2-5.el6.x86_64But now my system graphics is not starting. It is perfectly working in init 3.I have also changed the kernel parameters while booting:Added nomodeset and i915.modeset=0, but the problem remains same.  Update 1: As per suggestion of @slm, the output of lshw is as below:   [root@localhost ~]# lshw -c video  *-display UNCLAIMED            description: VGA compatible controller       product: Sandy Bridge Integrated Graphics Controller       vendor: Intel Corporation       physical id: 2       bus info: pci@0000:00:02.0       version: 09       width: 64 bits       clock: 33MHz       capabilities: msi pm vga_controller bus_master cap_list       configuration: latency=0       resources: memory:fe000000-fe3fffff memory:d0000000-dfffffff(prefetchable) ioport:f000(size=64)[root@localhost ~]#    The configuration part only contains configuration: latency=0, that means the driver part is missing, what I need to do?
