so I’ve set the video output according to this thread: VGA not working
Now if in LXDE desktop, using resolutions such as 960x600 or 800x600, if I open e.g. a terminal window and drag it around the screen a bit, it will move for a few seconds, then the desktop freezes (nothing moves, mouse cursor disappears) for about 30 seconds, then it wakes up again. This happens every time.
Can this be remedied?
