The display was wrong already at graphical installation from CD, but after to choose "without modprobe" option the display was ok again (in the FC3 there was not any problem with the display) and the upgrade was completed. After the first boot the display become to wrong again similar way (double contours and mismatching around the cursor). When I coming to the KDE and go out and after reboot with hard return (instead of normal/soft reboot) the display working properly. So probably some stupid automatism make the problems while the system shutting down. (At the normal shutdown the the screen is black with green frame instead of the text mode shutdown screen.) Graphic card is a Matrox G550 (the display setting is the same) and the monitor is an Acer 1711 17" TFT the monitor setting is +Generic LCD display 1280x1024" (because that monitor type there is no in the KDE display menu) What can I do? Thanks in advance: FB
