i have the same problem
i install 4363 in turbolinux8wks , my graphic card is MSI GF4MX440 , with PHILIPS 107P4 . when i startx , it works well , glxgear reports up . but when i quit to virtual consonle, the characters become a mess--each like a small snake. someone suggested use nvtv to push the button 'tv-off' and so on, but for me ,it doesn't work , and i toggle the FB on or off when the machine boot(vesafb option in grub.conf and setup the grub again), but it still fail. how can i do.
