[CentOS] Strange behavior in X, esp. VMWare Windows
Last Thursday, for some reason (possibly a power failure), my work desktop had a different video configuration than when I left Wednesday evening. I have two 17" flat panels configured as a two-head wide (side-by-side) single display. When I arrived on Thu, I had two individual desktops instead, the resolution was down to 800x600, and so on. The monitor type had been reset to generic 800x600, and the vido card was unknown. (This was not true before.) After a lot of fooling around with the xorg.conf file, I finally got it back to where it should be, for the most part. My current xorg.conf is included below. The problem is that I typically run certain apps on the right screen, including seamonkey and Windows under VMWare workstation, and since the new configuration came in, the mouse cursor is not where it should be. Items light up when I run the mouse over them, but a little below and to the right of the tip of the pointer. It is only a slight dislocation, but significantly worse in the Windows on VMWare, and it is really annoying when I have to mis-aim the cursor to hit certain selections (check boxes, bullets, etc.). Can anyone explain this? Here's my xorg.conf: # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "Default Layout" Screen 0 "aticonfig-Screen[0]" 0 0 Screen "aticonfig-Screen[1]" RightOf "aticonfig-Screen[0]" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" Option "Xinerama" "on" Option "Clone" "off" EndSection Section "Files" # RgbPath is the location of the RGB database.
