What types or graphic card are you using?

But, all i could say is that, it was working absolutely fine and all-of-a-sudden displaying a blank screen. If this was the problem right from when i installed the software, that is understandable. Not sure, why it worked before and not after. By googling, i found out that it could be a problem with configuration of some files in /etc/X11/ location ?? Below are the messages from /var/log/Xorg.0.log file, does these mean anything ? 753 [ 27.979] (II) No input driver specified, ignoring this device. 754 [ 27.979] (II) This device may have been added with another device file. 755 [ 27.979] (II) config/udev: Adding input device HDA Intel PCH Line Out CLFE (/dev/input/event16) 756 [ 27.979] (II) No input driver specified, ignoring this device. 757 [ 27.979] (II) This device may have been added with another device file. 758 [ 27.979] (II) config/udev: Adding input device HDA Intel PCH Line Out Side (/dev/input/event17) 759 [ 27.979] (II) No input driver specified, ignoring this device. 760 [ 27.979] (II) This device may have been added with another device file. 761 [ 27.979] (II) config/udev: Adding input device PC Speaker (/dev/input/event6) 762 [ 27.979] (II) No input driver specified, ignoring this device. 763 [ 27.979] (II) This device may have been added with another device file. 764 [ 27.983] reporting 6 9 18 141 765 [ 28.132] reporting 6 9 18 141 766 [ 28.183] reporting 6 9 18 141 Regards, Venkata B N
Hello, I have the same problem again today with CentOS-7. I re-installed with GNOME Desktop and also configured two VMs in it, all was working fine and i left the system locked overnight. When i tried to unlock the next day morning, screen only shows up black. Again, i cannot see the GUI. I can login to the system though. Any help would be appreciated here.
