Hi, Apologies for the long post - but I'm being driven crazy by this problem. A while ago I built a new server that is intended to serve as a Xen server running multiple DomU systems used a test environments for systems that I am working on. The host Xen system will be CentOS 5 as will some of the DomU systems. The systems will all be hardware virtualized. The motherboard uses the nVidia C15G chipset and the onboard graphix controller is recognised as a GeForce 6100. I am having problems getting the Video and mouse to work properly with CentOS 5 - both with as set of CD's downloaded when CentOS 5 was first released and with a DVD obtained from one of the local distro shops. The symptoms are that the Video is run in 800X600 mode and the mouse pointer works while the system is booting and while I am logging in to a GUI session. Once the login process has completed the mouse pointer disappears (is not visible at all). The mouse does however work as you can see changes to the Icons and menus on screen when moving the mouse around (blindly). The same situation obtains when running the system with FC7 installed. However when I boot the system using a Knoppix 5.1.1 live disk the Video resolution is 1024X768 and the mouse works properly. I attach the output of lspci and lsmod from both CentOS and Knoppix as well as the X86 Config file from Knoppix. Could someone please advise me on how to get CentOs to give the same results with the video and mouse as Knoppix.
