Hello, Eric! I have solved the problem! It was a stupid error, however only partially from my side I was told that the graphical card had 32 MB Video memory. In fact, it has only 16 MB.
So the switch in XF86Config VideoRam 16384 / VideoRam 32768 shows/hides the cursor Thank you for the help! > Well, this is a new one for me. One thing you might try: > Copy /etc/X11/XF86Config to /etc/X11/XF86Config.bak > Run XF86Setup, when it asks to use your old configuration, say no. > Then if you still don't get a cursor their must be something broken in > the X files you have. > Otherwise, try to reconfigure X and, if it works, try to find out what > might be different between the new XF86Config and the backup copy you > made.
